Note: Every care has been taken to ensure accuracy in preparation of this publication.

No liability can be accepted for any consequences, which may arise as a result of its application.

WARNING: Plumber – Be Aware

The solar hot and solar cold pipe work between the solar Premier Hiline storage tank and the solar

collectors are supplied in the pipe kit. The supplied copper solar hot and solar cold pipes MUST BE used.

If the solar water heater is installed either on a metal roof or in a trafficable area, such as on an

accessible roof, then the solar hot and solar cold pipes must be insulated. The solar hot and solar cold pipes may be required to be insulated to comply with local regulations.

If insulation is required, the full length of the solar hot and solar cold pipes MUST BE insulated.

The insulation must:

 be of a closed cell type or equivalent, suitable for a solar water heating application and capable

of withstanding the temperature of the closed circuit fluid generated by the solar collectors under stagnation conditions

The specification of the chosen insulation material should be checked with the insulation manufacturer prior to installation as different materials may vary in temperature tolerance.

 be at least 13 mm thick, however thicker insulation may be required to comply with the

requirements of AS/NZS 3500.4

 be weatherproof and UV resistant

 be fitted up to and cover the connections on both the solar storage tank and the solar collectors.

The insulation will offer corrosion protection to a metal roof against water runoff over the copper pipe, assist in avoiding accidental contact with the solar pipe work as high temperature closed circuit fluid can flow from the solar collectors to the solar storage tank and also reduce pipe heat losses.

Plastic pipe MUST NOT be used, as it will not withstand the temperature of the closed circuit fluid

generated by the solar collectors under stagnation conditions. The solar collectors can generate extremely high closed circuit fluid temperatures up to 150°C. Plastic pipe cannot withstand these temperatures and MUST NOT be used. Failure of plastic pipe can lead to the release of high temperature closed circuit fluid and cause damage.

There must be a continuous fall of a minimum 10° in the pipe work from the solar Premier Hiline

storage tank to the solar collectors. The highest point of the solar cold pipe and solar hot pipe must be where they connect to the solar Premier Hiline storage tank, otherwise thermosiphoning will not occur.

The solar water heater is to be isolated during the testing and commissioning of the heated water

reticulation system in a building, in accordance with Clause 11.1 and 11.3 (a) of AS/NZS 3500.4.

ABOUT YOUR WATER HEATER

WATER HEATER APPLICATION

This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable water. Its use in an application other than this may shorten its life.

MODEL TYPE

Your Rheem® solar Premier™ Hiline™ water heater is designed for both the solar collectors and the solar storage tank to be roof mounted. The solar storage tank has a Colorbond jacket and is suitable for installation with Rheem S200 solar collectors.

The system is suitable for installation in areas subject to frost or freeze conditions. Freeze conditions occur below 6°C.

This water heater is designed to be installed as an electric boosted solar water heater with its booster heating unit connected to a power supply, however it may be installed with an in-series continuous flow or storage booster.

If this water heater is installed with an in-series booster, then the electric booster heating unit will not be connected to a power supply and the references to the electric booster heating unit, thermostat and boosting controls in this Guide will not be applicable to the installation. For information relating to the function and operation of the in-series booster, refer to the Owners Guide and Installation Instructions supplied with the booster water heater.

SOLAR OPERATION

The Rheem solar Premier Hiline system has its stainless steel solar storage tank installed on the roof directly coupled to the solar collectors. This water heater is an indirect closed circuit solar hot water system with a heat exchanger in the solar storage tank.

The heat exchanger and solar collectors are connected by copper pipe work and form a closed circuit which is filled with closed circuit fluid. The closed circuit fluid is a solution of a blue, nontoxic food grade propylene glycol concentrate mixed with water. The closed circuit concentrate is used to lower the freezing temperature of the closed circuit fluid and provides protection against freezing. The closed circuit also provides protection to the solar collectors and solar pipe work against harsh water chemistry.

It works on the simple scientific fact that hot fluid rises. As the sun heats the closed circuit fluid in the solar collectors, the increase in temperature causes the fluid to rise through a copper pipe into the heat exchanger where it transfers its heat into the water in the solar storage tank. This allows cooler fluid from the heat exchanger to flow into the solar collectors to be heated by the

sun‟s energy. This process continues while solar energy is

available.

Automatic safety controls are fitted to the water heater to provide safe and efficient operation.

ELECTRIC BOOSTING

Water stored in the solar storage tank can be heated by an electric booster heating unit. The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy or rainy weather, or during the colder months. The solar Premier Hiline water heater is suitable for the heating unit to be connected to either a continuous, or a time of use, or an extended Off-Peak (overnight and day) or an OffPeak (overnight) electricity supply.

The booster heating unit is controlled by an electric thermostat. The thermostat and its over temperature energy cut out are mounted on the solar storage tank behind the side cover. The water temperature is automatically controlled to the thermostat setting when the booster heating unit is energised.

Page 5

ABOUT YOUR WATER HEATER

MAINS PRESSURE

The water heater is designed to operate at mains pressure by connecting directly to the mains water supply. If the mains supply pressure in your area exceeds that shown on page 20, a pressure limiting valve must be fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.

HOW HOT SHOULD THE WATER BE?

The temperature the system will operate at under solar radiation will depend upon the level of solar radiation available, orientation and inclination of the solar collectors, incoming cold water temperature and volume of hot water used.

Under normal household use, the system may achieve a water temperature of approximately twice the maximum daily outside air temperature. During periods high solar radiation conditions and low hot water consumption, the water temperature could exceed 85°C.

During periods of low solar energy gain, the water temperature can be boosted by the thermostatically controlled electric booster heating unit. Refer to “Booster Control” on page 7.

Rheem recommends the thermostat is set at 60°C to maximise solar contribution.

Note: AS 3498 requires that a water heater provides the means to inhibit the growth of Legionella bacteria in potable water. This water heater can satisfy this AS 3498 requirement provided the electric booster is energised for a sufficient period each day and the electric booster thermostat setting is 60°C or higher.

If this water heater is installed with an in-series continuous flow gas booster, then this requirement of AS 3498 can be satisfied provided the booster is energised, its preset outlet temperature setting is 70°C or higher and a remote temperature controller is not used.

If this water heater is installed with an in-series storage booster, then this requirement of AS 3498 can be satisfied provided the storage booster is energised and its thermostat setting is 60°C or higher.

HOTTER WATER INCREASES THE RISK OF SCALD INJURY

This water heater can deliver water at temperatures which can cause scalding. Check the water temperature before use, such as when entering a shower or filling a bath or basin, to ensure it is suitable for the application and will not cause scald injury.

We recommend and it may also be required by regulations that an approved temperature limiting device be fitted into the hot water pipe work to the bathroom and ensuite when this water heater is installed. This will keep the water temperature below 50°C at the bathroom and ensuite. The risk of scald injury will be reduced and still allow hotter water to the kitchen and laundry.

TEMPERATURE ADJUSTMENT

The water heater features a tradesperson adjustable thermostat. This requires a licensed tradesperson to make any temperature adjustments. The thermostat has a maximum temperature setting of 70°C and a minimum temperature setting of 60°C.

We advise you have your electrician adjust the thermostat to the lowest setting which meets your needs, especially if there are young children or elderly people in the home. Refer to “Hotter Water Increases the

Risk of Scald Injury” on page 5.

ABOUT YOUR WATER HEATER

WARNING

This water heater is only intended to be operated by persons who have the experience or the knowledge and the capabilities to do so. This water heater is not intended to be operated by persons with reduced physical, sensory or mental capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do not interfere with the water heater.

This water heater uses 240 V AC power for the electrically operated components. The removal of the side cover will expose 240 V wiring. It must only be removed by a qualified person.

Care should be taken not to touch the pipe work connecting the solar storage tank and the solar collectors. Very high temperature closed circuit fluid can be generated by the solar collectors and flow through the pipe work from the solar collectors to the solar storage tank.

Should the water from the water heater appear blue or if blue closed circuit fluid is noticed around the base of the water heater or solar collectors, this indicates a leak of the closed circuit fluid from the heat exchanger or the solar collectors. The closed circuit fluid is non-toxic and not hazardous to health. Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.

SAFETY

This water heater is supplied with a thermostat, an over-temperature cut-out, and a combination temperature pressure relief valve. These devices must not be tampered with or removed. The water heater must not be operated unless each of these devices is fitted and is in working order.

The operation of the over-temperature cut-out on the thermostat indicates a possibly dangerous situation. If the over-temperature cut-out operates, it must not be reset and the water heater must be serviced by a qualified person.

If the electrical conduit to the solar storage tank is damaged, it must be replaced by a qualified person in order to avoid a hazard. Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.

Warning: For continued safety of this water heater it must be installed, operated and maintained in

accordance with the Owner‟s Guide and Installation Instructions.

The Rheem warranty may not cover faults if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.

TEMPERATURE RUN DOWN

Temperature run down is the reduction in water temperature as the hotter water at the top of the storage cylinder transfers some of its heat to the cooler water in the lower section of the cylinder.

This effect is often perceived as heat loss, but is actually the redistribution of stored heat more evenly over the entire contents of the storage tank. This heat is not lost to the system.

Temperature run down is more noticeable the more hot water is used the night before and particularly if the booster heating unit and / or timer has been left off overnight. If higher temperature water is required, particularly in the morning, then use of the booster heating unit is necessary to raise the temperature of the water in the top section of the cylinder. Refer to “Booster Control” on page 7.

Page 7

ABOUT YOUR WATER HEATER

BOOSTER CONTROL

An isolating switch is installed in the electrical meter box for the solar storage tank. This should be left switched on to allow the booster heating unit to operate if required. The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy or rainy weather, or during the colder months.

The booster heating unit will only activate if heating is required and power is available from the switchboard. When the water is below the thermostat setting, the booster heating unit will turn on and heat the water. The booster heating unit will automatically turn off when the temperature of the water reaches the thermostat setting.

Leaving the isolating switch switched on will also provide a sufficient period of time each day for the booster heating unit to operate, if required, to satisfy the requirements of AS 3498.

The amount of water heated by the raised booster heating unit of the solar Premier Hiline storage tank will be 150 litres (300 litre model), or 90 litres (180 litre model).

Timer Control Switch

A suitably rated timer control switch can be installed and will help maximise energy savings with an electrically boosted solar water heater connected to a continuous, time of use or extended Off-Peak (overnight and day) electricity supply.

If used with an extended Off-Peak (overnight and day) electricity supply, the timer switch should:

be operated by a continuous power supply on its own circuit from the switchboard with the booster

heating unit operated by the Off-Peak power supply.

A double pole isolating switch is required to be installed at the switchboard to simultaneously isolate both circuits.

be of a type which has an internal rechargeable battery to keep time when the power supply is not

available to the timer.

Programming the Timer

Power must be available to the timer control switch before the booster heating unit can be activated.

The timer should be programmed:

to suit the hot water consumption pattern of the household,

with the end of the period to coincide with the commencement of the evening hot water usage,

to enable a boosting period of not less than the recommended continuous length of time for boosting,

and

for a period when power will be available for the booster heating unit to operate.

It may be necessary to program a second period into the timer, such as prior to the morning hot water usage.

Note: When daylight saving time applies, you may consider resetting the timer accordingly.

The recommended boosting periods are sufficient to allow the booster heating unit to heat up the boost volume of the solar storage tank to 60°C where the winter cold water temperatures do not fall below those shown. This may be necessary during periods of very low solar energy gain through the solar collectors, such as during constant rain or extremely cloudy weather, particularly in winter when the incoming cold water temperature is lower. The period will also provide a sufficient heat up time for the electric booster to operate, if required, to satisfy the requirements of AS 3498.

The booster heating unit will only activate if heating is required and power is available from the timer. When the water is below the thermostat setting, the booster heating unit will turn on and heat the water. The booster heating unit will automatically turn off either when the temperature of the water reaches the thermostat setting or at the end of the timer period, whichever comes first.

PIPE WORK AND INSULATION

The solar hot and solar cold pipe work between the solar Premier Hiline storage tank and the solar collectors are supplied in the pipe kit. The supplied copper solar hot and solar cold pipes MUST BE used.

If the solar water heater is installed either on a metal roof or in a trafficable area, such as on an accessible roof, then the solar hot and solar cold pipes must be insulated. The solar hot and solar cold pipes may be required to be insulated to comply with local regulations.

If insulation is required, the full length of the solar hot and solar cold pipes MUST BE insulated.

The insulation must:

be of a closed cell type or equivalent, suitable for a solar water heating application and capable of

withstanding the temperature of the water generated by the solar collectors under stagnation conditions

ABOUT YOUR WATER HEATER

FREEZE PROTECTION

This water heater is an indirect closed circuit solar hot water system with a heat exchanger in the solar storage tank. The heat exchanger and solar collectors form a closed circuit and are filled with closed circuit fluid. The closed circuit fluid is a solution of a blue, non-toxic food grade propylene glycol concentrate mixed with water. The closed circuit concentrate is used to lower the freezing temperature of the closed circuit fluid and provides protection against freezing.

During installation, the closed circuit concentrate is blended with water. The amount of closed circuit concentrate supplied with this water heater provides protection in frost prone areas to a temperature of -8°C. If lower temperatures are anticipated, a greater concentration of closed circuit fluid will be required.

The system has NO WARRANTY for freeze damage if non Rheem approved closed circuit fluid has been used or if the closed circuit fluid has been incorrectly mixed (refer to “Terms of the Rheem Warranty” on page 51).

RAIN WATER TANK

If the solar water heater is installed on a section of roof which is part of a rain water runoff collection system, then it is recommended this section of roof and its gutter be isolated from the rain water collection system. The gutter should be isolated to a width greater than the solar water heater and pipe work and must have suitable drainage. This is to ensure in the event of a leak from the closed circuit, a rainwater tank cannot be contaminated with closed circuit fluid.

The closed circuit fluid contains food grade additives (rust inhibitor and anti-freeze agent), is non-toxic and is harmless to the environment. However, if it enters a rain water tank it can cause an unpleasant odour to develop and result in the rain water tank having to be drained and cleaned.

PRECAUTIONS

Where damage to property can occur in the event of the water heater leaking, the water heater must be installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4 and all local codes and regulatory authority requirements.

The water heater must be maintained in accordance with the Owner‟s Guide and Installation Instructions.

Refer to “Regular Care” on page 11.

If this water heater is to be used where an uninterrupted hot water supply is necessary for your application or business you should ensure that you have back up redundancy within the hot water system design. This should ensure the continuity of hot water supply in the event that this water heater were to become inoperable for any reason. We recommend you seek advice from your plumber or specifier about your needs and building back up redundancy into your hot water supply system.

TO TURN OFF THE WATER HEATER

If you plan to be away from home for a few nights, we suggest you leave the water heater switched on.

If it is necessary to turn off the water heater:

Switch off the electrical supply at the isolating switch to the solar storage tank.

Close the cold water isolation valve at the inlet to the water heater.

TO TURN ON THE WATER HEATER

Open the cold water isolation valve fully at the inlet to the water heater.

Switch on the electrical supply at the isolating switch to the solar storage tank.

Check and if required reset the timer, if one is installed.

GOING ON HOLIDAYS

If you plan to be away from home, conserve energy by switching the booster switch “OFF”. Refer to “To Turn

Off The Water Heater” on page 9. Also if the system is not used for a period in excess of 4 weeks it is

recommended the solar collectors be covered.

The water heater is suitable for most public water supplies, however some water chemistries may have detrimental effects on the water heater, its components and fittings. Refer to “Water Supplies” on page 13.

If you are in a known harsh water area or you are not sure of your water chemistry, have your water checked against the conditions described on pages 13 to 14.

HOW LONG WILL THE WATER HEATER LAST?

The water heater is supported by a manufacturer‟s warranty (refer to page 51). There are a number of

factors that will affect the length of service the water heater will provide. These include but are not limited to the water chemistry, the water pressure, the water temperature (inlet and outlet) and the water usage pattern. Refer to “Precautions” on page 9.

Page 11

REGULAR CARE

MINOR SIX MONTH MAINTENANCE

It is recommended minor maintenance be performed every six months by the dwelling occupant.

The minor maintenance includes:

Operate the easing lever on the temperature pressure relief valve (if accessible). It is very important you

raise and lower the lever gently. Refer to “Temperature Pressure Relief Valve” on page 12.

If the relief valve lever is not readily and safely accessible, contact Rheem Service or their nearest Accredited Service Agent. Do not attempt to climb onto a non trafficable roof to operate the relief valve lever.

Warning: Exercise care to avoid any splashing of water, as water discharged from the drain line will

be hot. Stand clear of the drain line‟s point of discharge when operating the valve‟s lever.

Operate the easing lever on the expansion control valve (if fitted). It is very important you raise and

lower the lever gently. Refer to “Expansion Control Valve” on page 12.

Check the drain line from the safe tray (if one is installed) is not blocked.

MAJOR FIVE YEAR SERVICE

It is recommended a major five year service be conducted on the water heater.

Warning: Servicing of a water heater must only be carried out by a qualified person. Phone Rheem

Service or their nearest Accredited Service Agent.

Note: The five year service and routine replacement of any components, such as the anode and relief valves, are not included in the Rheem warranty. A charge will be made for this work. Only genuine replacement parts should be used on this water heater.

The major service includes the following actions:

Replace the temperature pressure relief valve.

Inspect and flush the expansion control valve (if fitted). If required, replace the valve.

Check the booster heating unit for excessive calcium build up or corrosion and replace if necessary.

Check the closed circuit fluid level.

Clean the collector glass.

Visually check the unit for any potential problems.

Inspect all connections.

Check the drain line from the safe tray (if one is installed) is not blocked.

Note: The solar storage tank may need to be drained during this service. After the completion of the service, the solar storage tank will take some time to reheat the water by solar gain. Depending upon the power supply connection to the booster heating unit, hot water may not be available until the next day.

Page 12

REGULAR CARE

TEMPERATURE PRESSURE RELIEF VALVE

This valve is near the top of the water heater and is essential for its safe operation. It is possible for the valve to release a little water through the drain line during each heating period. This occurs as the water is heated and expands by approximately 1/50 of its volume.

Continuous leakage of water from the valve and its drain line may indicate a problem with the water heater (refer to

“Temperature Pressure Relief Valve Running” on page 16).

Warning: Never block the outlet of this valve or its drain line

for any reason.

Operate the easing lever on the temperature pressure relief valve once every six months. It is very important you raise

and lower the lever gently.

DANGER: Failure to do this may result in the water heater

cylinder failing, or under certain circumstances, exploding.

Warning: Exercise care to avoid any splashing of water, as

water discharged from the drain line will be hot. Stand clear of

the drain line‟s point of discharge when operating the valve‟s

lever.

If water does not flow freely from the drain line when the lever is lifted, then the water heater must be checked. Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.

The temperature pressure relief valve should be replaced at intervals not exceeding 5 years, or more frequently in areas where there is a high incidence of water deposits (refer to “Water Supplies” on page 13).

EXPANSION CONTROL VALVE

In many areas, including South Australia, Western Australia and scaling water areas, an expansion control valve is fitted to the cold water line to the water heater. The expansion control valve may discharge a small quantity of water from its drain line during the heating period instead of the temperature pressure relief valve on the water heater.

Operate the easing lever on the expansion control valve once every six months. It is very important you raise and lower the lever gently. The expansion control valve should be checked for performance or replaced at intervals not exceeding 5 years, or more frequently in areas where there is a high incidence of water deposits.

COLLECTOR GLASS

Ensure the glass on your solar collectors is free of dust, salt spray or any other matter, which may reduce the effectiveness of the solar collectors. If the collector glass becomes dirty, hose down or if the solar collectors are accessible, wash the collector glass with water and a soft brush when the solar collectors are cool.

Have any trees trimmed which may shade the solar collectors.

Rheem solar collectors have passed the AS/NZS 2712 requirements for resistance to hailstone damage, so it is not normally necessary to fit a guard to a collector. Stone Guards are available to provide a level of protection to the collectors against vandalism or accidental damage. Refer to your local Solar Distributor for details.

WATER SUPPLIES

This water heater must be installed in accordance with this advice to be covered by the Rheem warranty.

This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chemistries which can have detrimental effects on the water heater and its operation and/or life expectancy. If you are unsure of your water chemistry, you may be able to obtain information from your local water supply authority. This water heater should only be connected to a water supply which complies with these guidelines for the Rheem warranty to apply.

CHANGE OF WATER SUPPLY

The changing or alternating from one water supply to another can have a detrimental effect on the operation and / or life expectation of a water heater cylinder and its heat exchanger, a temperature pressure relief valve and a heating unit.

Where there is a changeover from one water supply to another, e.g. a rainwater tank supply, bore water supply, desalinated water supply, public reticulated water supply or water brought in from another supply, then water chemistry information should be sought from the supplier or it should be tested to ensure the water supply meets the requirements given in these guidelines for the Rheem warranty to apply.

CHLORIDE AND PH

In a high chloride water supply, the water can corrode stainless steel parts and cause them to fail.

Where the chloride level exceeds 250 mg/L the Rheem warranty does not apply to a stainless steel cylinder and its heat exchanger in a Premier Hiline water heater.

pH is a measure of whether the water is alkaline or acid. In an acidic water supply, the water can attack stainless steel parts and cause them to fail.

Where the pH is less than 6.0 the Rheem warranty does not apply to a stainless steel cylinder and its heat exchanger in a Premier Hiline water heater. Water with a pH less than 6.0 may be treated to raise the pH.

The water supply from a rainwater tank in a metropolitan area is likely to be corrosive due to the dissolution of atmospheric contaminants. This may result in pH of less than 6.0. It is recommended an analysis on the water from a rainwater tank be conducted prior to connecting this type of water supply to a water heater with a stainless steel cylinder.

Refer to the pH and Chloride chart on page 13.

SATURATION INDEX

The saturation index is used as a measure of the water‟s corrosive or scaling properties.

In a corrosive water supply, the water can attack copper parts and cause them to fail. Where the saturation index is less than –1.0, the water is very corrosive and the Rheem warranty does not apply to a copper sheathed heating unit. A corrosion resistant heating unit must be used for the Rheem warranty to apply to the heating unit. This water heater is supplied fitted with a corrosion resistant heating unit.

In a scaling water supply calcium carbonate is deposited out of the water onto any hot metallic surface.

Where the saturation index exceeds +0.40, the water is very scaling. An expansion control valve must be fitted on the cold water line after the non-return valve to protect and for the Rheem warranty to apply to the temperature pressure relief valve and water heater cylinder.

Where the saturation index exceeds +0.80, the Rheem warranty does not apply to a standard watts density heating unit. A low watts density heating unit must be used for the Rheem warranty to apply to the heating unit.

Water which is scaling may be treated with a water softening device to reduce the saturation index of the water.

Refer to the Saturation Index chart on page 14. Refer to the cold water connection detail on page 37 for the position of the expansion control valve.

Contact Rheem Service or their nearest Accredited Service Agent if a replacement heating unit is required.

Check the items below before making a service call. You will be charged for attending to any condition or fault that is not related to manufacture or failure of a part.

NOT ENOUGH HOT WATER (OR NO HOT WATER)

This can occur with new installations and is normally related to some misunderstandings as to the use of the booster heating unit.

Insufficient sunlight

Insufficient sunlight due to cloudy weather during hotter months or low solar energy contribution in colder months may mean the booster heating unit is required to boost more often.

Ensure the booster heating unit is being used as advised. Refer to

“Booster Control” on page 7.

Booster heating unit not operating

Inspect the isolating switch marked “HOT WATER” or “WATER HEATER” at the switchboard and ensure it is turned “ON”.

Check the timer (if one is installed) and its settings to ensure power is available to the booster heating unit.

Note: Check the electricity supply to which the unit is connected. If on an Off-Peak or time controlled electricity supply remember heating hours are restricted.

Check the fuse marked “HOT WATER” or “WATER HEATER” at the switchboard.

Collectors shaded

If trees or other objects shade the solar collectors or if the glass is dirty, the effectiveness of the solar collectors will be greatly reduced. Have the trees trimmed or the solar collectors relocated if the obstruction is permanent or clean the collector glass (refer to “Collector Glass” on page 12).

Are you using more hot water than you think?

Is one outlet (especially the shower) using more hot water than you think?

Very often it is not realised the amount of hot water used, particularly when showering. Carefully review the family‟s hot water usage. As you have installed an energy saving appliance, energy saving should also be practised in the home. Adjust your water usage pattern to take advantage of maximum solar gains.

Have your plumber install a flow control valve to each shower outlet to reduce water usage.

Temperature pressure relief valve running

Is the relief valve discharging too much water?

Refer to “Temperature Pressure Relief Valve Running” on page 16.

Thermostat setting

Ensure the thermostat setting is appropriate. You may choose to have your electrician adjust the thermostat upwards to gain additional hot water capacity when boosting.

Refer to “Temperature Adjustment” on page 5.

Warning: Hotter water increases the risk of scald injury.

Water heater size

Do you have the correct size water heater for your requirements?

The sizing guides in the sales literature and on the Rheem website (www.rheem.com.au) suggest average sizes that may be needed.

Page 16

WATER NOT HOT ENOUGH

You may find that due to heavy hot water usage or low solar energy gain the water temperature may be lower than normally expected. Ensure the booster is being used as advised. If a timer is installed, you will need to carefully plan your use of the booster heating unit to boost the water temperature on such occasions. Refer to “Booster Control” on page 7.

A lower water temperature may also be noticed in the morning when the booster heating unit has not been energised overnight. This in particular may be experienced during periods of low solar energy gain and can be caused by the transfer of heat energy overnight to the cold water in the lower portion of the solar storage tank, or if there has been heavy hot water usage the previous night. Refer to “Temperature Run Down” on page 6.

TEMPERATURE PRESSURE RELIEF VALVE RUNNING

Normal Operation

It is normal and desirable this valve allows a small quantity of water to escape during the heating cycle. However, if it discharges more than a bucket full of water in 24 hours, there may be another problem.

Continuous dribble

Try gently raising the easing lever on the relief valve for a few seconds (refer to “Temperature Pressure Relief Valve” on page 12). This may dislodge a small particle of foreign matter and clear the fault. Release the lever gently.

Steady flows for long period (often at night)

This may indicate the mains water pressure sometimes rises above the designed pressure of the water heater. Ask your installing plumber to fit a pressure limiting valve.

Warning: Never replace the relief valve with one of a higher pressure rating.

Heavy flows of hot water until the water heater is cold - then stops until water reheats

If this occurs when the water heater is being boosted by the electric booster heating unit, then the water heater must be switched off at the isolating switch or switchboard. Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.

This may also occur during periods of increased solar gain in the hotter months and particularly if there is a reduced level of hot water consumption. It is most likely to happen during the daytime.

One of the functions of the temperature pressure relief valve is to relieve the tank of excess energy, i.e. when water temperature increases to a high level. This higher temperature water is replaced with incoming cold water to reduce the energy level inside of the tank. The valve will close when cooler water surrounds the temperature probe of the valve. As this is a function of the temperature pressure relief valve under these conditions, it is not necessary to make a service call.

EXPANSION CONTROL VALVE RUNNING

An expansion control valve fitted in the cold water line to the water heater (refer to page 37) may discharge a small quantity of water instead of the temperature pressure relief valve on the water heater. The benefit is that energy is conserved as the discharged water is cooler.

COLLECTOR GLASS

The Rheem warranty DOES NOT cover breakage of solar collector glass. Check your household insurance policy covers collector glass breakage.

Warning: No attempt should be made to remove or replace broken collector glass.

The collector glass is not offered as a replacement part. Should the solar collector require replacement, contact Rheem Service or their nearest Accredited Service Agent.

HIGHER THAN EXPECTED ELECTRICITY BILLS

With the installation of your new solar hot water system, maximum electrical energy savings can be achieved with careful planning of hot water usage. Should you at any time feel your electricity account is higher than expected, we suggest you check the following points:

Is the relief valve running excessively?

Refer to “Temperature Pressure Relief Valve Running” on page 16.

Is one outlet (especially the shower) using more hot water than

you think?

Refer to “Not Enough Hot Water” on page 15.

Is there a leaking hot water pipe, dripping hot water tap, etc?

Even a small leak will waste a surprising quantity of hot water and energy. Replace faulty tap washers, and have your plumber rectify any leaking pipe work.

Are you using the booster heating unit properly?

Refer to “Booster Control” on page 7.

Has there been an increase in hot water usage?

An increase in hot water usage may result in an increase in booster operation.

Has your water heating tariff rate been increased by your electricity retailer since your previous account?

ELECTRICITY TARIFFS

The electricity tariff to which your solar water heater is connected will play an important role in the overall effectiveness of the system. It is important you are aware of this tariff to enable you to take full advantage of the boosting period, i.e. Domestic / Continuous or Time of Use, Extended Off-Peak (overnight and day) or extended time controlled, or Off-Peak (overnight) or time controlled.

IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU NEED ASSISTANCE, PHONE RHEEM SERVICE OR THEIR NEAREST ACCREDITED SERVICE AGENT.

INSTALLATION

THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING.

The system is suitable for installation with Rheem S200 solar collectors.

IMPORTANT NOTES

Working on roofs is and should always be considered a hazardous activity, particularly early in the

morning, late in the evening, when the roof is wet or during and after periods of rain.

All work must be carried out in accordance with Local, State and Federal Occupational Safety, Health

and Welfare Regulations. In particular, the requirements for safety whilst manual lifting, working at heights and on roofs.

Installers must be competently trained in:

 Height Hazard Assessment

 Working at Height Procedures

 Assessment / Use / Wearing of correct height safety equipment (harnesses etc.)

 All other relevant safety factors specific to the installation and maintenance work to be compliant

with suitable Occupational, Health and Safety Regulations / Codes.

All relevant permits shall be obtained from the regulatory authorities before commencing work to install

the solar hot water system.

All work carried out must be performed by appropriately qualified tradespeople or be suitably supervised

for trades assistant duties.

Every care must be taken to protect and warn occupants of the building and the public from personal

injury which may occur from falling tools, roof materials, fittings or any other hazards of a general nature.

Advise the occupants of any inconvenience which may occur due to disconnection of existing water and

electrical supplies.

The connection, attachment, integration or general association of other equipment or parts which either

directly or indirectly affect the operation or performance of this equipment could void the Rheem warranty.

All packaging materials must be removed from the solar storage tank prior to its installation. Refer to the

warning on page 29 in relation to the removal of the solar collector packaging.

FREEZE PROTECTION

The system is suitable for installation in areas subject to frost or freeze conditions. Freeze conditions occur below 6°C. The system has NO WARRANTY for freeze damage if non Rheem approved closed circuit fluid has been used or if the closed circuit fluid has been incorrectly mixed (refer to “Terms of the Rheem

Warranty” on page 51).

The system is supplied with closed circuit concentrate. During installation and commissioning the closed circuit concentrate is blended with water in the appropriate proportion to achieve the required frost protection. The amount of closed circuit concentrate supplied with this water heater provides protection in frost prone areas to a temperature of -8°C. If a lower temperature protection is required, a larger amount of closed circuit concentrate will be needed. The storage cylinder must be filled with water before charging the closed circuit with closed circuit fluid. Refer to “Closed Circuit Fluid” on page 45.

Page 19

INSTALLATION

INSTALLATION STANDARDS

The water heater must be installed:

by a qualified person, and

in accordance with the installation instructions, and

in compliance with Standards AS/NZS 3500.4, AS/NZS 3000 and all local codes and regulatory authority

requirements.

In New Zealand, the installation must also conform with Clause G12 of the New Zealand Building Code.

Victorian Installers

Notice to Victorian Installers from the Victorian Plumbing Industry Commission if this solar water heater is installed in a new Class 1 dwelling in the State of Victoria. The system model number is to be recorded on the Certificate of Compliance. It is also a requirement to provide the householder with permanent

documentation recording the system model number exactly as it is shown in the „List of systems capable of

complying with the regulations‟ published by Sustainability Victoria (see www.sustainability.vic.gov.au). This documentation may be in the form of an indelible label adhered to the solar storage tank, or other suitable form placed in an accessible location, such as the meter box, for later inspection.

WATER HEATER APPLICATION

This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable water. Its use in an application other than this may shorten its life.

If this water heater is to be used where an uninterrupted hot water supply is necessary for the application or business, then there should be redundancy within the hot water system design. This should ensure the continuity of hot water supply in the event that this water heater was to become inoperable for any reason. We recommend you provide advice to the system owner about their needs and building backup redundancy into the hot water supply system.

Page 20

INSTALLATION

SOLAR WATER HEATER STORAGE TANK LOCATION

The solar storage tank is designed to be installed on the roof directly coupled to the solar collectors. The solar water heater should be installed close to the most frequently used outlet and its position chosen with safety and service in mind. The solar water heater should be installed with a north facing aspect (refer to

“Solar Collector Location” on page 28).

The solar water heater must not be installed with an inclination of less than 10° or greater than 45°. The water heater may not thermosiphon or will not perform efficiently.

Clearance must be allowed for servicing of the solar storage tank. Make sure the temperature pressure relief valve lever is accessible and the side cover, thermostat and booster heating unit can be removed for service. You must be able to read the information on the rating plate.

Remember you may have to remove the entire solar storage tank later for servicing. The solar storage tank must be capable of being removed without structural alteration to the building or major alteration to the piping.

For a single water heater installation, follow the diagrams on pages 26 to 27. For multiple water heater installations, follow the instructions on pages 43 and 44.

SAFE TRAY

MAINS WATER SUPPLY

Where the mains water supply pressure exceeds that shown in the table below, an approved pressure limiting valve is required and should be fitted as shown in the installation diagram (refer to diagram on

page 37).

TANK WATER SUPPLY

If the water heater is supplied with water from a tank supply and a pressure pump system is not installed, then the bottom of the supply tank must be at least 1 m above the highest point of the hot water plumbing system, including the water heater. Care must be taken to avoid air locks. The cold water line to the water heater should be adequately sized and fitted with a full flow gate valve or ball valve.

Page 21

INSTALLATION

RAIN WATER TANK

If the solar collectors and solar pipe work are to be installed on a section of roof which is part of a rain water runoff collection system, then it is recommended this section of roof and its gutter be isolated from the rain water collection system. The gutter should be isolated to a width greater than the solar collectors and pipe work and must have suitable drainage. The installer should ensure in the event of a leak from the solar collectors or pipe work, a rainwater tank cannot be contaminated with closed circuit fluid.

While the closed circuit fluid is non toxic to humans, it does have an adverse effect on water stored in rainwater tanks. It can cause an unpleasant odour to develop, render the rainwater foul and unfit for human consumption and result in the rain water tank having to be drained and cleaned.

The section of roof and gutter should be isolated from the rainwater collection system before the commissioning of the solar water heater, so that any leak or spillage during commissioning does not make its way into the rainwater tank.

This section of roof and guttering can be isolated by either:

blocking this section of gutter from the remaining gutter and fitting two separate down pipes, one to take

any run-off water from that section of roof away to drain and the other to the rainwater collection side of the gutter to take the rain water runoff to the rain water tank.

blocking this section of gutter from the remaining gutter and fitting a tube or pipe of a material

compatible with the gutter material in this section of the gutter and penetrating the separation pieces at either end to allow rainwater runoff to pass from one part of the rainwater collection system to the other. It may be necessary to fit a down pipe to the section of blocked gutter to take any run-off water from that section of roof away to drain.

installing a false gutter inside of the existing gutter, with a down pipe penetrating the existing gutter to

take any run-off water from that section of roof away to drain. The false gutter should be no deeper than half of the depth of the existing gutter, so as to enable rain water runoff to flow under the false gutter.

installing a flashing from the underside of the roofing material, with a continuous fall, to over the outside

lip of the gutter. The flashing should extend wider than the collectors and pipe work and turned up at the ends so if there is leakage of closed circuit fluid, it cannot enter the gutter.

If any of these solutions are not practical, then the installer should discuss alternative options to suit the installation with the house holder. Any alterations to the roof drainage system must comply with the relevant building regulations, codes and Standards.

INSTALLATION

HOT WATER DELIVERY

This water heater can deliver water at temperatures which can cause scalding.

It is necessary and we recommend that a temperature limiting device be fitted between the water heater and the hot water outlets in any ablution area such as a bathroom or ensuite, to reduce the risk of scalding. The installing plumber may have a legal obligation to ensure the installation of this water heater meets the delivery water temperature requirements of AS/NZS 3500.4 so that scalding water temperatures are not delivered to a bathroom, ensuite or other ablution area.

The temperature limiting device used with a solar water heater should have a specified „minimum temperature differential‟ between the hot water inlet and the tempered water outlet of no greater than 10°C. In addition, a temperature limiting device capable of receiving a hot water supply temperature of up to 99°C should be used in conjunction with a Rheem Premier Hiline thermosiphon closed circuit system. Refer to the specifications of the temperature limiting device.

Where a temperature limiting device is installed adjacent to the solar water heater, the cold water line to the temperature limiting device can be branched off the cold water line either before or after the isolation valve, pressure limiting valve and non return valve to the indirect closed circuit solar storage tank. If an expansion control valve is required, it must always be installed after the non return valve and be the last valve prior to the solar storage tank.

If a pressure limiting valve is installed on the cold water line to the solar water heater and the cold water line to a temperature limiting device branches off before this valve or from another cold water line in the premises, then a pressure limiting valve of an equal pressure setting may be required prior to the temperature limiting device.

Two Temperature Zones Using a Temperature Limiting Device

Page 23

INSTALLATION

CIRCULATED HOT WATER FLOW AND RETURN SYSTEM

A solar water heater should not be installed as part of a circulated hot water flow and return system in a building. The benefits of solar gain will be significantly reduced and energy gained from the sun lost through the pipe work.

If a circulated flow and return system is required, it is necessary to bypass the solar water heater and install a secondary water heater connected to the hot water flow and return line and supplied from the solar water heater. The secondary water heater must be a storage water heater able to provide a hot water outlet temperature of at least 60°C. Note: The thermostat must always be set to at least 60°C. Refer to the

diagram on page 23.

Temperature Limiting Device

A temperature limiting device cannot be installed in circulated hot water flow and return pipe work. The tempered water from a temperature limiting device cannot be circulated. Where a circulated hot water flow and return system is required in a building, a temperature limiting device can only be installed on a dead leg, branching off the circulated hot water flow and return pipe.

If circulated tempered water were to be returned back to the water heater, depending on the location of the return line connection on the water supply line to the water heater, then either:

water will be supplied to the cold water inlet of the temperature limiting device at a temperature

exceeding the maximum recommended water supply temperature, or

when the hot taps are closed no water will be supplied to the cold water inlet of the temperature limiting

device whilst hot water will continue to be supplied to the hot water inlet of the temperature limiting device.

These conditions may result in either water at a temperature exceeding the requirements of AS/NZS 3500.4 being delivered to the hot water outlets in the ablution areas, or the device closing completely and not delivering water at all, or the device failing. Under either condition, the operation and performance of the device cannot be guaranteed.

Circulated Hot Water Flow and Return System – Solar Water Heater

Page 24

INSTALLATION

REDUCING HEAT LOSSES

The cold water line to and the hot water line from the water heater must be insulated in accordance with the requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed.

The pipe work between the solar storage tank and the solar collectors may be required to be insulated. Refer to “Warning: Plumber Be Aware” on page 30.

SADDLING - PIPE WORK

To prevent damage to the cylinder when attaching pipe clips or saddles to the water heater jacket, we recommend the use of self-drilling screws with a maximum length of 13 mm. Should pre drilling be required, extreme caution must be observed when penetrating the jacket of the water heater.

Note: If the cylinder is damaged as a result of attaching pipe clips or saddles to the jacket, any resultant faults will not be covered by the Rheem warranty.

BOOSTER HEATING UNIT

The booster heating unit provides hot water during periods of low solar gain. This can be connected to either a continuous, or a time of use, or an extended Off-Peak (overnight and day) or an Off-Peak (overnight) electricity supply. Boosting can be controlled via a timer. Refer to “Booster Control” on page 40.

If this water heater is installed with an in-series booster, then the electric booster heating unit in the solar storage tank will not need to be connected to a power supply.

INSTALLATION – SOLAR COLLECTORS

SOLAR COLLECTOR LOCATION

The solar collectors must be installed in a shade free position.

The surrounding vicinity should be checked for higher buildings or trees which may cause shade at other

times of the year and for small trees which may grow and shade the solar collectors in the future.

For optimum performance, solar collectors should be

installed facing towards the equator (i.e. north facing in the southern hemisphere and south facing in the northern hemisphere). ALWAYS CHECK ORIENTATION WITH A COMPASS. Where this orientation is not practical, solar collectors facing up to 45° from the equator will receive about 4% less total solar radiation.

Inclination of the solar collectors should be

approximately equal to 90% of the local latitude angle, but never more than 45°. The latitudes of some

Australian cities are listed on page 29. The thermosiphon

solar water heater may be installed at the roof angle for simplicity of installation and appearance, but must never be less than 10° from the horizontal. If the roof angle varies by 15° from the optimum angle, the solar collectors will receive about 10% less total solar radiation.

The water heater is suitable for installations with an inclination of up to 30°. Where the solar water

heater is installed at inclinations greater than 30°, a With Pitch frame and tank frame mounting kit are necessary. Refer to your local Solar Distributor for details.

For a solar Premier Hiline installation on a roof with a pitch less than 10°, a Fixed Pitch frame and a tank

frame mounting kit are required. Refer to your local Solar Distributor for details.

For an installation of a thermosiphon solar water heater in a cyclonic or high wind area, a suitable With

Pitch frame and a tank frame mounting kit are required. Refer to your local Solar Distributor for details.

The installation of this solar water heater with a tank frame mounting kit on a suitable frame, subject to

the frame‟s design criteria not being exceeded:

 is suitable for installation in geographic locations up to and within Wind Region D (With Pitch frame)

or up to and within Wind Region C (Fixed Pitch frame), as defined in the Building Code of Australia, Australian / New Zealand Standard AS/NZS 1170.2:2002 and the Australian Standard AS 40552006, and

 also provides an acceptable method of installation where it is necessary to satisfy the requirements

of the Building Code of Australia and AS/NZS 3500.4 Clause 6.5.3.4 for high wind areas.

The installer must ensure the structural integrity of the building is not compromised by the installation of

the solar water heater and the roof structure is suitable to carry the full weight of the solar storage tank and the solar collectors. If in doubt the roof structure should be suitably strengthened. Consult a structural engineer.

The solar storage tanks, when full of water, weigh approximately 495 kg (300 litre) and 292 kg

(180 litre). Each solar collector and its fittings weighs up to approximately 60 kg when full of closed circuit fluid.

The installation must comply with the requirements of AS/NZS 3500.4 and all local codes and regulatory

authority requirements.

Notes:

All plumbing work must be carried out by a qualified person and in accordance with the requirements of

the Standard AS/NZS 3500.4, and all local codes and regulatory authority requirements. In New Zealand, the installation must conform with Clause G12 of the New Zealand Building Code.

Pipe work, including that within the roof space, is to be securely fixed to prevent vibration.

These solar collectors have passed the AS/NZS 2712 requirements for resistance to hailstone damage,

so it is not normally necessary to fit a guard to a collector. Stone Guards are available to provide a level of protection to the collectors against vandalism or accidental damage. Refer to your local Solar Distributor for details.

The Rheem warranty DOES NOT cover breakage of solar collector glass. Check your insurance policy

covers collector glass breakage.

Warning: No attempt should be made to remove or replace broken collector glass.

The collector glass is not offered as a replacement part. Should the solar collector require replacement, contact your local Solar Distributor for details.

Warning: Do not remove the solar collector packaging completely, prior to the installation as the

solar collector surface can become very hot. Remove only sufficient packaging material to enable the installation of the solar collectors.

Upon completion of the installation of the solar water heater the packaging material may be removed from the S200 solar collectors, whether or not the solar water heater is commissioned.

The solar collector packaging must be removed completely prior to the permanent operation of the water heater.

All connectors, end plugs, „washers, brass fittings, collector straps, collector angle and temperature

pressure relief valve required for the installation are included with the pipe kit.

Suitable screws or anchors will be required to fix the collector straps to the rafters for a pitched roof installation.

Warning: Where straps, frames, etc. are secured to roof members, all fixings must be of an appropriate type to suit the type of member. Inadequate or inappropriate fixings may result in straps becoming unsecured and the installation of the solar hot water system becoming unsafe.

Use thread sealing tape or an approved thread sealant on all but the conetite fittings.

If the solar storage tank is being installed with existing solar collectors, then utilise the existing

temperature pressure relief valve, fittings and pipes used on the installation.

INSTALLATION – SOLAR COLLECTORS

WARNING: Plumber – Be Aware

The solar hot and solar cold pipe work between the solar Premier Hiline storage tank and the solar

collectors are supplied in the pipe kit. The supplied copper solar hot and solar cold pipes MUST BE used.

If the solar water heater is installed either on a metal roof or in a trafficable area, such as on an

accessible roof, then the solar hot and solar cold pipes must be insulated. The solar hot and solar cold pipes may be required to be insulated to comply with local regulations.

If insulation is required, the full length of the solar hot and solar cold pipes MUST BE insulated.

The insulation must:

 be of a closed cell type or equivalent, suitable for a solar water heating application and capable

of withstanding the temperature of the closed circuit fluid generated by the solar collectors under stagnation conditions

The specification of the chosen insulation material should be checked with the insulation manufacturer prior to installation as different materials may vary in temperature tolerance.

 be at least 13 mm thick, however thicker insulation may be required to comply with the

requirements of AS/NZS 3500.4

 be weatherproof and UV resistant

 be fitted up to and cover the connections on both the solar storage tank and the solar collectors.

Plastic pipe MUST NOT be used, as it will not withstand the temperature of the closed circuit fluid

There must be a continuous fall of a minimum 10° in the pipe work from the solar Premier Hiline

The solar water heater is to be isolated during the testing and commissioning of the heated water

reticulation system in a building, in accordance with Clause 11.1 and 11.3 (a) of AS/NZS 3500.4.

DO NOT MODIFY THESE PARTS IN ANY WAY.

Note: Use thread sealing tape or an approved thread sealant on all fittings.

1. Water Heater Location: Select a suitable position for the solar water heater.

Refer to “Solar Water Heater Storage Tank Location” on page 20 and “Solar Collector Location” on page 28.

2. Position of Tank: Select the position of the solar storage tank so the front of the foot is toward the nose

of an even row of tiles or even metal roof sheet above a roof batten. The rear of the foot may be seated over the nose of the tiles on the next row behind. Where possible, the tank should be positioned at least three tiles from the ridge capping to prevent disturbance of the ridge.

3. Pitched Roof Installation: Determine the location of the collector rail (13). Measure down the roof

2070 mm from the position of the foot of the solar storage tank to determine the location of the collector rail (13).

Hook the two collector straps (14) to the collector rail (13).

Note: The solar collectors must be installed at an angle from the horizontal. Use a spirit level to determine the horizontal. Ensure the end of the collector rail at the right hand outlet side of the solar collectors is between:

 12 – 15 mm (for one solar collector), or

 24 – 30 mm (for two solar collectors)

higher up the roof from the horizontal than the left hand end of the collector angle(s) at the inlet side of the solar collectors.

This is to ensure there is sufficient angle rise from left to right to achieve thermosiphon operation. Failure to adhere to this requirement may result in reduced solar performance from the solar water heater.

If the roof material is not even where the collectors are to be installed, then it may be necessary to add 10 mm for each collector in the array to the above distances. It is important that the solar hot outlet is the highest point in the collector waterway so the system functions efficiently.

Tile Roof: Remove the tiles on the next row above the position of the collector rail (13) to expose the rafters. Ensure the collector rail (13) is at the correct angle from the horizontal. Once in position, fix the collector straps (12) to the rafters, using suitable screws or anchors. Replace the tiles.

Metal Roof: Ensure the collector rail (13) is at the correct angle from the horizontal. Once in position, fix the collector straps (12) to the rafters, through the metal roofing material, using suitable screws or anchors. Care should be taken not to mark Colorbond® or other metal roof sheet with a marking pen and to remove all swarf from the metal roof as these can cause deterioration of the metal roofing material.

Note: Fixings must penetrate only through the high point in the roof material profile.

Solar Stand – Across Pitch or Against Pitch: Determine the location of the Flat Roof stand and the Across Pitch or Against Pitch stand. Assemble and fix the stands to the roof, following the instructions provided with the stands. Ensure the collector rail is at the correct angle from the horizontal to achieve the required rise across the solar collectors.

Solar Stand – Flat Roof Installation: Determine the location of the Flat Roof stand. Assemble and fix the stand to the roof, following the installation instructions provided with the stand. Ensure the collector rail is at the correct angle from the horizontal to achieve the required rise across the solar collectors.

4. Solar Collectors: Position the solar collectors in the correct configuration with the lower ends seated in

the collector rail (13).

5. Collector Unions: For a 300 litre model with two solar collectors, couple the solar collectors together

using the collector unions (5) supplied in the pipe kit. Refer to Detail C on page 36 for details.

6. Clamps and Fixing Collector (Bottom): Ensure the solar collectors are well seated in the collector rail.

Clamp the solar collectors (two clamps per collector) to the collector rail, using the clamps (11) and hex screws, washers and nuts (26) provided.

7. Solar storage tank:

Tile Roof: If used, fit the tank flashing sheet (not shown) under the top of the solar collectors and extend up the roof to the top of the solar storage tank location. Lift the roof tiles immediately above the solar storage tank location and secure the flashing sheet to the roofing members. Ensure the flashing sheet makes the section of roof under the tank waterproof. Locate the Tank to Collector spacers (24) against the top end of the solar collectors (one per collector).

Metal Roof: Locate the Tank to Collector spacers (24) against the top end of the solar collectors (one per collector).

Position the solar storage tank in place above the Tank to Collector spacers.

8. Collector Connections of Pipe Work: Install the solar cold pipe (long pipe) (15) supplied to the bottom

left connection of the solar collectors and the solar hot pipe (short pipe) (1) supplied to the top right connection of the solar collectors.

9. Tank Connections of Pipe Work: Connect the solar cold pipe (15) to the heat exchanger connection

on the left hand end of the solar storage tank. Connect the solar hot pipe (1) to the heat exchanger connection on the right hand end of the solar storage tank.

10. Fill Plug: Fit the fill plug (21) to the bottom right connection of the solar collectors using the collector

gland nut (4) provided. Refer to Detail A on page 36 for details.

11. Fill / Drain Label: Attach the Fill / Drain label adjacent to the Fill Plug (21).

12. Collector Bung: Fit the collector bung (6) to the top left connection of the solar collector using the

collector gland nut (4) provided.

13. Tank Straps: On a pitched roof installation, position and hook the tank straps (17) into the louvres at the

back and underneath of the tank support foot.

Tile Roof: Remove the tiles on the next row above the position of the solar storage tank to expose the rafters. Once in position, fix the tank straps to the rafters using suitable screws or anchors. Replace the tiles.

Metal Roof: once in position, fix the tank straps to the rafters, through the metal roofing material, using suitable screws or anchors. The tank straps may be cut to a length of approximately 400 mm to retain the aesthetics of the installation.

Note: Fixings must penetrate only through the high point in the roof material profile.

SYSTEM ASSEMBLY

14. Pressure Relief Valve: Fit the 200 kPa pressure relief valve (16) to the top connection on the right hand

side of the solar storage tank using the retaining clip (20) provided. Refer to Detail B on page 36 for details.

The pressure relief valve and retaining clip are transported behind the electrical cover at the left hand end of the tank.

15. Protective Film: Peel the protective plastic film from the solar storage tank and the solar collectors. The

protective plastic will bake on and deteriorate if exposed to sunlight, reducing the aesthetics of the installation and become difficult to remove.

16. Plumbing and Electrical Connections: Refer to “Connections – Plumbing” on page 37 for details on

the cold water and hot water plumbing and “Connections – Electrical” on page 40 for details on the electrical connection.

Notes:

 Penetrations through the roofing material must be:

 at the high point of the roof tile or metal sheet;

 made neatly and kept as small as practicable;

 waterproofed upon installation of the hot and cold pipes.

 Exposed pipe work between the solar storage tank and the penetrations through the roofing

material should be kept to a minimum to maintain the aesthetics of the installation.

17. Closed Circuit Filling: Refer to “Closed Circuit Fluid” on page 45 for details on filling the closed circuit

with the closed circuit fluid.

Asbestos Roofs

All Occupational Health and Safety matters / procedures must be adhered to in relation to asbestos material. If safety procedures are not adhered to then terminal illness may result from the handling of asbestos.

Care needs to be taken when fixing straps to asbestos roofs. It is suggested that longer Tek screws are used to fit securely into purlins.

Pitch roofs - Greater than 30°

The solar water heater must not be installed on a roof with a pitch greater than 45°.

For installations on a roof with a pitch between 30° and 45°, the water heater is to be installed on a With Pitch frame.

INSTALLATION CHECK LIST

Once the installation is completed and the system is full of water, it is IMPORTANT to check the following:

The right hand side of the collector array is between

 12 – 15 mm (for one solar collector), or

 24 - 30 mm (for two solar collectors)

higher up the roof from the horizontal than the left hand side of the collector array. If in doubt use a spirit level.

The solar hot and solar cold pipes grade downwards with a continuous fall of not less than 10° from the

solar storage tank to the solar collectors. If in doubt use a spirit level.

CONNECTIONS – PLUMBING

All plumbing work must be carried out by a qualified person and in accordance with the requirements of the Standard AS/NZS 3500.4, and all local codes and regulatory authority requirements. In New Zealand, the installation must conform with Clause G12 of the New Zealand Building Code.

Warning: Certain types of plastic pipe, such as Poly-butylene pipe, are not suitable to be used as a hot

water pipe between:

this water heater and a temperature limiting device, and

this water heater and a hot water outlet if a temperature limiting device is not installed.

This water heater can produce water at a temperature and pressure which can exceed the performance limits of these types of pipe. This may result in pipe failure leading to severe water damage to the property. If one of these types of plastic pipe is used as a hot water pipe in the property, then a temperature limiting device must be installed between the water heater and this pipe work.

Note: The solar storage tank of a solar water heater should not be installed as part of a circulated hot water flow and return system in a building. The benefits of solar gain will be significantly reduced and energy gained from the sun lost through the pipe work. If a circulated flow and return system is required, it is necessary to connect the return line after the solar storage tank and prior to the in-series water heater supplied from the solar water heater. Refer to “Circulated Hot Water Flow and Return System” on page 23.

CONNECTION SIZES

Hot water connection: G¾B / G½.

Cold water connection: DN20 copper tube.

(connection to tank: G¾B).

Relief valve connection: RP½/15.

WATER INLET AND OUTLET

All pipe work must be cleared of foreign matter before connection and purged before attempting to operate the water heater. All olive compression fittings must use brass or copper olives. Use thread sealing tape or approved thread sealant on all fittings.

An isolation valve and non return valve must be installed on the cold water line to the water heater. An acceptable arrangement is shown in the diagram

and on page 44 for multiple installations. Refer also

to “Hot Water Delivery” on page 22 and to “Mains

Water Supply” on page 20.

The cold water isolation valve and expansion control valve, if one is installed, must be accessible from ground or floor level. A position of up to 1800 mm above ground or floor level is recommended. They must not be installed either on the roof or in the ceiling space, unless it is an accessible trafficable area. Extend the cold water line to the cold water inlet fitting on the solar storage tank.

A disconnection union must always be provided at the cold water inlet and hot water outlet of the water heater to allow for disconnection of the water heater.

The pipe work from the hot water outlet must not be installed in front of or prevent access to the electrical cover of the water heater.

Page 38

CONNECTIONS – PLUMBING

Pipes must not be installed in direct contact with metal roofs. Where it is necessary to run piping across a metal roof, it must be fixed above the roof and surrounded with a weatherproof insulation of a minimum thickness in accordance with Clause 4.12.3 of AS/NZS 3500.4. The insulation must be UV resistant if exposed. The insulation is to assist in freeze protection and to protect the metal roof against corrosion by water runoff over the copper pipe. Consideration should be made for thermal expansion and contraction of the roof material.

Exposed pipe work between the solar storage tank and the penetrations through the roofing material should be kept to a minimum to maintain the aesthetics of the installation.

Notes:

Penetrations through the roofing material must be:

 at the high point of the roof tile or metal sheet;

 made neatly and kept as small as practicable;

 waterproofed upon installation of the hot and cold pipes.

PIPE SIZES

To achieve true mains pressure operation, the cold water line to the water heater should be the same size or bigger than the hot water line from the water heater.

The pipe sizing for hot water supply systems should be carried out by persons competent to do so, choosing the most suitable pipe size for each individual application. Reference to the technical specifications of the water heater and local regulatory authority requirements must be made.

IN-SERIES BOOSTER (IF INSTALLED)

The pipe work between the solar storage tank and an in-series booster has a minimum recommended pipe size of DN20, MUST BE of copper and be fully insulated with a closed cell type insulation or equivalent and in accordance with the requirements of AS/NZS 3500.4.

The insulation must be weatherproof and UV resistant if exposed. The insulation must be fitted up to the connections on both the solar storage tank and the in-series booster.

An isolation valve must be installed on the water line to the in-series booster. The isolation valve must be of a full flow type if the in-series booster is a continuous flow water heater.

TEMPERATURE PRESSURE RELIEF VALVE

The temperature pressure relief valve is supplied in the pipe kit. The temperature pressure relief valve must be fitted to the end of the hot water outlet Tee before the water heater is operated. Before fitting the relief valve, make sure the probe has not been bent. Seal the thread with Teflon tape - never hemp. Make sure the tape does not hang over the end of the thread.

Screw the valve into the correct opening (refer to the installation diagrams on pages 26 to 27) leaving the valve drain pointing downwards. Do not use a wrench on the valve body - use the spanner flats provided. A copper drain line must be fitted to the temperature pressure relief valve (refer to "Relief Valve Drain" on page 39).

The valve must be insulated with closed cell polymer insulation or similar (minimum thickness 9 mm) and the insulation installed so as not to impede the operation of the valve. The insulation must be weatherproof and UV resistant if exposed.

Page 39

CONNECTIONS – PLUMBING

EXPANSION CONTROL VALVE

An expansion control valve is supplied in the pipe kit and must be installed. Install the expansion control valve using the brass Tee, brass union and brass nipple supplied in the pipe kit on the cold water line to the water heater.

Local regulations may make it mandatory to install an expansion control valve (ECV) in the cold water line to the water heater. In other areas, an ECV is required if the saturation index is greater than +0.4 (refer to

“Water Supplies” on page 13).

The expansion control valve must always be installed after the non return valve and be the last valve installed prior to the water heater (refer to diagrams on page 37). A copper drain line must be fitted to the expansion control valve (refer to "Relief Valve Drain" on page 39).

The expansion control valve and it‟s easing gear must be accessible from ground or floor level. A position of up to 1800 mm above ground or floor level is recommended. It must not be installed either on the roof or in the ceiling space, unless it is an accessible trafficable area. Extend the cold water line from the expansion control valve to the cold water inlet fitting on the water heater.

RELIEF VALVE DRAIN

DN15 copper drain lines must be fitted to the temperature pressure relief valve and expansion control valve to carry the discharge clear of the water heater. Connect the drain lines to the valves using disconnection unions. The drain line from the valve to the point of discharge should be as short as possible, have a continuous fall all the way from the water heater to the discharge outlet and have no tap, valves or other restrictions in the pipe work.

The drain line from the temperature pressure relief valve also must not be installed in front of or prevent access to the electrical cover of the water heater.

A drain line from a relief valve must comply with the requirements of AS/NZS 3500.4.

A drain line must be no longer than 9 metres with no more than three bends greater than 45° before discharging at an outlet or air break. The maximum length of 9 metres for a drain line is reduced by 1 metre for each additional bend required of greater than 45°, up to a maximum of three additional bends. Where the distance to the point of final discharge exceeds this length, the drain line can discharge into a tundish.

Subject to local regulatory authority approval, the drain lines from the temperature pressure relief valve and expansion control valve from an individual water heater may be interconnected.

The outlet of a drain line must be in such a position that flow out of the pipe can be easily seen, but arranged so discharge will not cause injury, damage or nuisance. The termination point of a drain line must comply with the requirements of AS/NZS 3500.4. Drain lines must not discharge into a safe tray.

In locations where water pipes are prone to freezing, drain lines must be insulated, must not exceed 300 mm in length and are to discharge into a tundish through an air gap of between 75 mm and 150 mm.

If a drain line discharges into a tundish, the drain line from the tundish must be not less than DN20. The drain line from a tundish must meet the same requirements as for a drain line from a relief valve.

Where a drain line crosses over a metal roof, the pipe work must be fully insulated with weatherproof lagging to offer corrosion protection to the metal roof against water runoff over the copper pipe. The insulation must be UV resistant if exposed.

For multiple installations the drain lines from several water heaters can discharge into a common tundish (refer to “Multiple Installations” on pages 43 and 44).

Warning: As the function of the temperature pressure relief valve on this water heater is to discharge high temperature water under certain conditions, it is strongly recommended the pipe work downstream of the relief valve be capable of carrying water exceeding 93°C. Failure to observe this precaution may result in damage to pipe work and property.

Page 40

CONNECTIONS – ELECTRICAL

The power supply to the water heater must not be switched on until the water heater is filled with water and a satisfactory megger reading is obtained.

All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the Wiring Rules AS/NZS 3000 and all local codes and regulatory authority requirements.

If this water heater is installed with an in-series booster, then the electric booster heating unit will not need to be connected to a power supply and the references to the electric booster heating unit, thermostat and boosting controls in these installation instructions will not be applicable to the installation.

SOLAR STORAGE TANK

The solar storage tank with an electric booster heating unit must be directly connected to a 240 V AC 50 Hz mains power supply with an isolating switch installed at the switchboard.

The power supply can be either a continuous, or a time of use, or an extended Off-Peak (overnight and day) or an Off-Peak (overnight) electricity supply. Discuss the power supply requirements with the householder.

A flexible 20 mm conduit is required for the electrical cable to the solar storage tank. The conduit is to be connected to the unit with a 20 mm terminator. Connect the power supply wires directly to the terminal block and earth tab connection, ensuring there are no excess wire loops inside the front cover.

THERMOSTAT SETTING

The thermostat is adjustable from 60°C to 70°C. The thermostat is adjusted by turning the adjuster anticlockwise to decrease the temperature setting and clockwise to increase the temperature setting. Only adjust the temperature setting when the isolating switch is switched off at the switchboard.

For reasons of safety and economy, we advise the thermostat be set at the lowest temperature that will provide sufficient hot water during periods when boosting is required. Rheem recommends the thermostat is set at 60°C to maximise solar contribution. Discuss the thermostat setting requirements with the householder.

BOOSTER CONTROL

The isolating switch installed in the electrical meter box for the solar storage tank should be left switched on.

Leaving the isolating switch switched on will also provide a sufficient period of time each day for the booster heating unit to operate, if required, to satisfy the requirements of AS 3498.

Timer Control Switch

If used with an extended Off-Peak (overnight and day) electricity supply, the timer switch should:

be operated by a continuous power supply on its own circuit from the switchboard with the booster

heating unit operated by the Off-Peak power supply.

A double pole isolating switch is required to be installed at the switchboard to simultaneously isolate both circuits.

be of a type which has an internal rechargeable battery to keep time when the power supply is not

available to the timer.

Page 41

CONNECTIONS – ELECTRICAL

Programming the Timer

Power must be available to the timer control switch before the booster heating unit can be activated.

The timer should be programmed:

to suit the hot water consumption pattern of the household,

with the end of the period to coincide with the commencement of the evening hot water usage,

to enable a boosting period of not less than the recommended continuous length of time for boosting,

and

for a period when power will be available for the booster heating unit to operate.

It may be necessary to program a second period into the timer, such as prior to the morning hot water usage. Check with the householder.

The recommended continuous length of time for boosting is:

MULTIPLE INSTALLATIONS

A multiple installation of Rheem solar Premier Hiline water heaters on a single manifold or multiple manifolds is possible, using the Rheem Equa-Flow® manifold system, where large volumes of hot water are required. It is recommended the electrical heating units of Rheem solar Premier Hiline water heaters installed in a multiple installation, not be connected to a power supply. Rheem heavy duty water heaters should be installed in series with the solar water heaters to boost the water temperature during periods of poor or no solar gain.

The cold water and hot water manifolds must be designed to balance the flow from each solar storage tank. To achieve this, there are basic installation requirements and principles which must be followed:

1. The maximum number of solar storage tanks in a bank should be 8, however several banks of solar

storage tanks can be installed.

2. The hot water line from the manifold must leave from the opposite end to which the cold water line

enters the manifold.

3. The solar storage tanks must be of the same model.

4. The cold water line, cold and hot water headers and hot water line must be sized to meet the

requirements of both AS/NZS 3500.4 and the application.

5. A non return valve, isolation valve and if required a pressure limiting valve and expansion control valve,

must be installed on the cold water line to the system.

6. A full flow gate valve or ball valve (not stop taps, as used on a single solar storage tank installation)

must be installed on both the cold water branch and hot water branch of each solar storage tank.

7. Non return valves or pressure limiting valves must not be installed on the branch lines to the solar

storage tanks.

8. All fittings, valves and branch lines must be matched sets all the way along the manifold.

9. Sufficient space must be left to enable access, servicing or removal of each solar storage tank.

10. The temperature pressure relief valve drain line from each solar storage tank can terminate at a

common tundish (funnel) with a visible air break at each drain discharge point (refer to the diagram on

page 44 and to “Relief Drain Line” on page 39).

Refer to the diagram on page 44 for installation and plant layout details.

COMMISSIONING

TO FILL AND TURN ON THE WATER HEATER

The power supply to the solar storage tank must not be switched on until the water heater is filled with water and a satisfactory megger reading is obtained.

Open all of the hot water taps in the house (don‟t forget the shower).

Open the isolation valves fully on the cold and hot water branches to the water heater(s) in a bank.

Open the cold water isolation valve fully on the cold water line to the water heater(s).

Air will be forced out of the taps.

Close each tap as water flows freely from it.

Check the pipe work for leaks.

Fill the closed circuit heat exchanger and solar collectors with the closed circuit fluid. Refer to “Closed

Circuit Fluid” on page 45.

Switch on the electrical supply at the isolating switch to the solar storage tank(s).

Set the timer if one is installed (refer to “Booster Control” on page 40).

Explain to the householder or a responsible officer the functions and operation of the water heater and the timer if one is installed. Upon completion of the installation and commissioning of the water heater, leave this guide with the householder or responsible officer.

CLOSED CIRCUIT FLUID

Important: It is recommended the solar storage tank be filled with water before charging the solar heat

exchanger with the closed circuit fluid.

The closed circuit concentrate is supplied in 1.5 litre bottles. Mix the required quantity of closed circuit concentrate with the correct quantity of water to achieve the correct closed circuit fluid for the system. Failure to mix the closed circuit fluid correctly may void the Rheem warranty.

Caution: Although the closed circuit fluid is of food grade and non toxic, care must be taken not to accidentally consume or spill any of the closed circuit fluid when handling. Refer to “Material Safety Data” on page 47 . Only use approved closed circuit fluid.

Warning: Although non-toxic, the following first aid advice and procedures should be followed if the

closed circuit concentrate comes into human contact or is spilt:

Swallowed - give milk or water and seek medical attention.

Eyes - wash with running water.

Skin - remove contaminated clothing and wash skin with water and soap.

Inhaled - seek fresh air, rest and keep warm.

Spilt - immediately remove contaminated clothing, stop leak source, absorb with a dry agent and

eliminate any ignition sources nearby.

Page 46

COMMISSIONING

To Fill The Closed Circuit

It is necessary to fill the heat exchanger and solar collectors with closed circuit fluid before the water heater can be operated. Refer to diagram on page 46.

Note: Care must be taken to ensure there is no spillage of the closed circuit fluid onto the roof surface, particularly if the roof is part of a rain water collection system. Any spilled closed circuit fluid must be cleaned up immediately and the roof surface cleaned of any fluid residue.

To fill the heat exchanger:

Remove the retaining clip and 200 kPa pressure relief valve from the tank vent socket located on the

right hand end of the solar storage tank.

This will allow air to escape during filling.

Connect a hose to the service valve located at the bottom right hand corner of the right hand solar

collector.

Using a funnel placed in the end of the hose, pour the required contents of the closed circuit fluid into

the system through the funnel. Top up with water until the level of fluid reaches the bottom of the vent socket.

Insert the 200 kPa pressure relief valve into the vent socket and secure with the retaining clip.

Remove the hose and close the service valve.

Clean up any spilt closed circuit fluid.

Check the system for leaks.

It is recommended the closed circuit fluid level is checked three (3) months after commissioning of the

system to ensure the fluid level has not dropped due to incorrect filling or fluid has not been lost due to leaks in the system.

The closed circuit fluid level should be checked every five (5) years and if required the closed circuit fluid

replaced.

The closed circuit fluid contains food grade additives (rust inhibitor, anti-freeze agent, colour) and is harmless to the environment. However, it is good practice to recover any excess closed circuit fluid and remove from site.

DRAINING THE SOLAR STORAGE TANK

To drain the solar storage tank:

Cover the solar collectors to prevent solar radiation gain and the transfer of heat to the solar storage

tank.

Failure to do so may cause a safety issue.

Open a hot water tap and allow the water to run for five minutes immediately prior to draining the solar

storage tank.

This will assist in the transfer of any heat from high temperature closed circuit fluid in the solar collectors to the water in the solar storage tank.

Close the hot water tap.

Warning: Exercise care to avoid splashing of water, as water discharged from the solar storage tank may be of a very high temperature.

Note: The water discharged from the solar storage tank may contain sediments and should be diverted away from any rainwater tank connected to the roof.

Turn off the water heater (refer to “To Turn Off the Water Heater” on page 47).

Close all hot water taps.

Operate the closed circuit pressure relief valve on the right side of the solar storage tank to relieve the

pressure from the closed circuit.

Warning: Relieved air or closed circuit fluid may be hot.

Operate the temperature pressure relief valve release lever on the left hand side of the solar storage

tank - do not let the lever snap back or you will damage the valve seat.

Operating the lever will release the pressure in the solar storage tank.

Undo the union at the cold water inlet to the solar storage tank and attach a hose.

Let the other end of the hose go to a drain.

Operate the relief valve again.

This will let air into the solar storage tank and allow the water to drain through the hose.

DRAINING THE CLOSED CIRCUIT

It is recommended to drain the solar collectors and heat exchanger every five years. The closed circuit fluid should be checked and if necessary replaced. Draining the solar collectors and closed circuit should be conducted within three hours of sunrise, when the closed circuit fluid temperature inside the solar collectors is lower.

To drain the solar collectors and closed circuit:

Cover the solar collectors to prevent solar radiation gain.

Failure to do so may cause a safety issue.

Open a hot water tap and allow the water to run for five minutes immediately prior to draining the solar

storage tank.

This will assist in the transfer of any heat from high temperature closed circuit fluid in the solar collectors to the water in the solar storage tank.

Close the hot water tap.

Warning: Exercise care to avoid splashing of closed circuit fluid, as fluid discharged from the solar collectors may be of a very high temperature.

Note: The closed circuit fluid discharged from the solar collectors can render the water in a rain water tank unusable and should be diverted away from any rainwater tank connected to the roof.

Operate the closed circuit pressure relief valve on the right side of the solar storage tank to relieve the

pressure from the closed circuit.

Warning: Relieved air or closed circuit fluid may be hot.

Open the service valve at the bottom right corner of the solar collectors and attach a hose.

Place the end of the hose into a container.

Remove the retaining clip and the closed circuit pressure relief valve from the tank vent socket.

Allow the closed circuit fluid to drain into a container and dispose of in accordance with the relevant local

authority.

Warning: Closed circuit fluid may be hot.

To fill the solar collectors, refer to “To Fill The Closed Circuit” on page 46.
