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 pipes between the solar storage tank and the solar collectors MUST BE

of copper. All compression fittings must use brass or copper olives.

 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

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 if exposed

 extend through any penetrations in the eaves, ceiling and roof

 cover valves and fittings in the solar hot and solar cold pipe work

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

Note: Failure to observe these requirements increases the risk of freeze damage.

Uninsulated pipe work, including concealed in cavities and roof spaces or where it may be in contact with a metal roof, may lead to freeze damage. The system has NO WARRANTY for freeze damage if the solar hot and solar cold pipes are not insulated in accordance with the installation instructions.

The insulation is essential to assist in providing freeze protection, 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 water 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 and pressure of the water

generated by the solar collectors under stagnation conditions. The solar collectors can generate extremely high water temperatures up to 150°C and high water pressure of 1000 kPa. Plastic pipe cannot withstand these temperatures and pressures and MUST NOT be used. Failure of plastic pipe can lead to the release of high temperature water and cause severe water damage and flooding.

 The highest point of the solar cold pipe and solar hot pipe must be where they connect to the solar

collectors, to avoid the possibility of air locks occurring in the system. There must be a continuous fall in the pipe work between the solar collectors and solar storage tank. Horizontal runs of pipe work are acceptable and may be installed.

 A non return valve MUST BE installed on the cold water line to the solar storage tank AFTER the

cold water branch to a temperature limiting device. Due to the higher water temperatures generated under certain conditions in the solar collectors of this solar water heater, an additional effective backflow prevention device also should be used as an extra safeguard. Valve manufacturer RMC recommends Dual Check Valve model N7150, as being suitable for this application.

 The pressure applied to the solar circuit and solar collectors during a pressure test of a direct open

circuit system MUST NOT exceed 1000 kPa, otherwise damage may result to the solar collectors. Refer to “Pressure Testing” on page 34.

ABOUT YOUR WATER HEATER

MODEL TYPE

Your Rheem® Loline® open circuit solar water heater is designed for the solar collectors to be roof mounted and the solar storage tank to be installed at ground level. The solar storage tank is suitable for either outdoor or indoor installation and can be installed with Rheem NPT 200 or HBT 200 solar collectors. The system is not suitable for installation above 400 metres altitude.

The system has a level of freeze protection designed to guard the system against damage from freeze conditions (refer to “Freeze Protection” on page 8). The system must be installed with the full length of the solar hot and solar cold pipes insulated to offer protection against freeze damage (refer to “Pipe Work and

Insulation” on page 8). Freeze conditions occur below 6°C.

The system has NO WARRANTY for freeze damage when installed above 400 metres altitude or if the solar hot and solar cold pipes are not insulated in accordance with the installation instructions (refer to “Warranty

Exclusions” on page 47). Note: Warranty against freeze damage applies only to systems installed in

Australia.

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 Loline open circuit system has its vitreous enamel lined solar storage tank installed at ground or floor level, remotely from the solar collectors.

As the sun heats the water in the solar collectors the increase in temperature activates the circulator. The circulator then moves the water from the solar collectors through an insulated copper pipe to the solar storage tank. The circulator switches on whenever the water in the solar collectors is hotter than the water in the tank. Cooler water from the solar

storage tank is circulated to the solar collectors to be heated by the sun‟s

energy.

This process continues while solar energy is available and until the water in the solar storage tank reaches a temperature of 70°C to 75°C.

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 Loline 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 Off-Peak (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 front 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 22, a pressure limiting valve must be fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved. A minimum water supply pressure of 200 kPa is required to enable the solar circulator and solar circuit system to operate effectively.

HOW HOT SHOULD THE WATER BE?

The solar control unit will circulate water through the solar collectors until a temperature of 70°C to 75°C is reached.

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 6.

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 electrical power for operation of the control systems and the electrically operated components. The removal of the front cover will expose 240 V wiring. It must only be removed by an authorised or qualified person.

The power lead from the solar controller must be plugged into a weatherproof electrical outlet if installed outdoors. Take care not to touch the power plug with wet hands.

Care should be taken not to touch the pipe work connecting the solar storage tank and the solar collectors. Very high temperature hot water can be generated by the solar collectors under certain conditions and flow through the pipe work from the solar collectors to the solar storage tank.

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 an authorised or qualified person.

If the power supply cord or plug to the solar control unit or the electrical conduit to the solar storage tank is damaged, it must be replaced by an authorised person in order to avoid a hazard. The power supply cord and plug must be replaced with a genuine replacement part available from Rheem. 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 warranty can become void if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.

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 your Loline storage tank will be 285 litres (430 model), 200 litres (340 model) or 160 litres (270 model).

ABOUT YOUR WATER HEATER

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.

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

The timer control switch 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,

 for a period when power will be available to the timer.

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 continuous length of time for boosting is:

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.

ABOUT YOUR WATER HEATER

FREEZE PROTECTION

The system has a level of freeze protection designed to guard the system against damage from freeze conditions. The system must be installed with the full length of the solar hot and solar cold pipes insulated to offer protection against freeze damage (refer to “Pipe Work and Insulation” on page 8). Freeze conditions occur below 6°C.

Exclusions” on page 47). Note: Warranty against freeze damage applies only to systems installed in

Australia.

The anti freeze control is designed to recirculate a small amount of water from the solar storage tank through the solar pipe work during periods of low temperatures. This is to prevent the water inside the pipe work from freezing. It is essential that the electrical circuit to the solar control unit is continually turned on if there is a risk of freezing. The solar warranty does not cover damage caused by freeze conditions when the electrical circuit to the solar control unit is turned off or interrupted.

Notes:

 If it is necessary to switch the power off to the solar control unit and there is a risk of freezing, then it is

necessary to have your plumber drain the solar collectors and solar flow and return pipe work.

 The freeze protection system will be rendered inoperable if electrical power is not available at the solar

control unit. Damage caused by freezing due to no power at the solar control unit, is not covered by warranty.

 The system is not covered for freeze damage above 400 metres altitude.

 Refer to “Warranty Exclusions” on page 47.

PIPE WORK AND INSULATION

The solar hot and solar cold pipe work between the solar storage tank and the solar collectors and between the solar storage tank and in-series booster (if one is installed) MUST BE of copper.

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

 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 if exposed

 extend through any penetrations in the eaves, ceiling and roof

 cover valves and fittings in the solar hot and solar cold pipe work

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

Note: Failure of these requirements to be observed increases the risk of freeze damage.

Uninsulated pipe work, including concealed in cavities and roof spaces or where it may be in contact with a metal roof, may lead to freeze damage. There is NO WARRANTY for freeze damage if the solar hot and solar cold pipes are not insulated in accordance with the installation instructions.

Plastic pipe MUST NOT be used, as it will not withstand the temperature and pressure of the water generated by the solar collectors under certain conditions (refer to Warning on page 33).

ABOUT YOUR WATER HEATER

SOLAR MONITOR

A solar monitor is located on the side of the solar control unit and houses a green and a red LED.

The green LED, marked “Solar”, indicates the current operational mode of the solar water heater and the red LED, marked “Attention”, indicates a fault mode.

The green LED will emit either a constant glow or a series of flashes, with a 2 second interval between each series.

The red LED will emit a series of flashes, with a 2 second interval between each series, only if there is a particular fault condition with the system.

The operational modes are:

Flashes

If the power supply to the solar control unit is on and the green LED is off or the red LED is flashing, this indicates there may be a fault with the water heater. The red LED may emit up to six flashes in each series of flashes.

Notes:

 If the system is in standby mode with the green LED emitting either a constant glow or slow pulsing

flashes (circulator is off) and the solar storage tank is full of hot water, the red LED may simultaneously emit a constant glow if solar radiation is still being received by the solar collectors. This does not indicate a fault. The red LED will go out when the temperature in the solar collectors decreases.

 During periods of high solar radiation and the circulator activates after having been off (the green LED

will emit either a rapid pulse or a series of three flashes), it is possible the red LED may simultaneously emit a rapid pulse for a period of up to ten (10) minutes. This does not indicate a fault.

If the red LED continues to emit a rapid pulse for longer than ten (10) minutes, or emits a series of flashes, then count the number of flashes and phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.

ABOUT YOUR WATER HEATER

BLEEDING THE SOLAR COLLECTORS

It is necessary to purge air from the collector circuit:

 When the water heater is to be turned on and the solar collectors and solar hot and solar cold pipes

have been drained.

 After maintenance has been conducted on the pipe work and air has entered the system.

 If the circulator appears not to be circulating water around the system.

Warning: Bleeding the solar collectors should be conducted in the morning, within three hours of

sunrise, when the water temperature inside the solar collectors is lower.

To purge air from the collector circuit:

 Ensure the water heater is full of water and all of the hot

taps are turned off.

 Using a flat blade screwdriver, open the bleed valve (if it is

not already open) fitted adjacent to the solar hot water (from collector) inlet of the solar storage tank (see diagram).

 The mains pressure will force water to flow from the tank

and through the pipe work, expelling air from the collector circuit through the bleed valve. This is evidenced by spurting of water from the drain line connected to the bleed valve.

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

 Close the bleed valve when water runs freely from the

drain line.

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.

 Switch off the electrical supply at the power outlet to the solar control unit (refer to note below).

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

Note: If there is a risk of freezing conditions, the electrical supply to the solar control unit should not be switched off unless the solar collectors are drained, otherwise damage could result (refer to “Freeze

Protection” on page 8).

Page 11

ABOUT YOUR WATER HEATER

TO TURN ON THE WATER HEATER

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

 If the solar collectors and solar hot and solar cold pipes have been drained, it will be necessary to bleed

the collector circuit (refer to “Bleeding the Solar Collectors” on page 10).

If the electrical supply to the water heater has been switched off:

 Switch on the electrical supply at the power outlet to the solar control unit. The power outlet must be

switched on for the solar control unit to operate and solar gain to be achieved.

 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.

HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?

Installation requirements are shown on pages 27 and 30. The water heater must be installed by an authorised person and the installation must comply with Standards AS/NZS 3500.4, AS/NZS 3000 and all local codes and regulatory authority requirements. In New Zealand, the installation must conform with Clause G12 of the New Zealand Building Code.

Refer also to “Pipe Work and Insulation” on page 8.

VICTORIAN CUSTOMERS

Notice to Victorian Customers from the Victorian Plumbing Industry Commission. This water heater must be installed by a licensed person as required by the Victorian Building Act 1993.

Only a licensed person will give you a Compliance Certificate, showing that the work complies with all the relevant Standards. Only a licensed person will have insurance protecting their workmanship for 6 years. Make sure you use a licensed person to install this water heater and ask for your Compliance Certificate.

DOES THE WATER CHEMISTRY AFFECT THE WATER HEATER?

The water heater is suitable for most public water supplies, however some water chemistries may have detrimental effects on the cylinder, solar collectors and fittings. If you are in a known harsh water area you

must read page 14. If you are not sure, have your water chemistry checked against the conditions described on page 14.

HOW LONG WILL THE WATER HEATER LAST?

There are a number of factors that will affect the length of service the water heater will provide. These include the water chemistry, the water pressure, temperature (inlet and outlet) and the water usage pattern. However, your water heater is supported by a comprehensive warranty (refer to page 48).

GOING ON HOLIDAYS

If you plan to be away from home, conserve energy by switching the booster switch “OFF”. It is not necessary to switch off the electrical supply at the power outlet to the solar control unit. Refer to “To Turn Off

The Water Heater” on page 10. Also if the system is not used for a period in excess of two (2) weeks it is

recommended the solar collectors be covered.

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 18).

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.

If water does not flow freely from the drain line when the lever is lifted, then the water heater should be checked by Rheem Service or their nearest Accredited Service Agent.

The temperature pressure relief 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 (refer to “Water Supplies” on page 14).

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.

REGULAR CARE

FLUSHING THE SOLAR COLLECTORS

It may be necessary to flush the solar collectors if there is sediment in the water supply. This should be conducted in the morning, within three hours of sunrise.

To flush the solar collectors:

 Open a hot water tap and allow the water to run for five (5) minutes prior to flushing the solar

collector(s).

 Close the hot tap.

 Wait a further five (5) minutes before attempting to flush the solar collectors.

This will assist in the transfer of any high temperature water in the solar collector(s) to the solar storage tank.

Warning: Exercise care, as water discharged from the solar collectors may be of a very high temperature.

 To flush the solar collectors, follow the procedure “Bleeding the Solar Collectors” on page 10, allowing

the water to flow from the bleed valve drain line for five minutes before closing the bleed valve.

It is recommended to flush the solar collectors every five years. This will assist in keeping the solar collectors, solar cold pipe and solar hot pipe clear of sediment.

Page 14

WATER SUPPLIES

This water heater must be installed in accordance with this advice to be covered by the 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 water heater 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, a temperature pressure relief valve, a heating unit and a solar collector in a direct solar water heater system.

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 warranty to apply.

ANODE

The vitreous enamel lined cylinder of the water heater is only covered by warranty when the total dissolved solids (TDS) content in the water is less than 2500 mg/L and when the correct colour coded anode is installed. The use of an incorrect colour coded anode will void the cylinder warranty and may shorten the life of the water heater cylinder.

The correct colour coded anode must be selected and fitted to the water heater in accordance with the following advice and the Anode Selection chart on page 14 for warranty to apply to the water heater cylinder.

The anode installed in your water heater will slowly dissipate whilst protecting the cylinder. The life of the water heater cylinder may be extended by arranging for an authorised person to inspect the anode and replace if required.

The suggested time after installation when the anode should be inspected is 8 years.

For water supplies which are either softened, desalinated or where the water supply may alternate between a water tank and a reticulated public supply or another supply, it is recommended the anode be inspected 3 years earlier than shown (refer to “Anode” on page 14).

CAUTION

If, under these conditions, the water heater has not been used for two or more weeks the following procedure should be carried out before using any electrical appliances (automatic washing machines and dishwashers) which are connected to the hot water supply.

The hydrogen, which is highly flammable, should be vented safely by opening a hot tap and allowing the water to flow. There should be no smoking or naked flame near the tap whilst it is turned on. Any hydrogen gas will be dissipated. This is indicated by an unusual spurting of the water from the tap. Once the water runs freely, any hydrogen in the system will have been released.

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 warranty does not apply to a copper sheathed heating unit or a solar collector in a direct solar water heater system. A corrosion resistant heating unit must be used for warranty to apply to the 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 warranty to apply to the temperature pressure relief valve and water heater cylinder. Solar collectors in a direct solar water heater system should be covered when the water heater is not intended to be used for more than two weeks.

Where the saturation index exceeds +0.80, warranty does not apply to a standard watts density heating unit or a solar collector in a direct solar water heater system. A low watts density heating unit must be used for 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 16.

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

Refer to the cold water connection detail on page 35 for the position of the expansion control valve.

SAVE A SERVICE CALL

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 6.

 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 it‟s 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 supply, remember heating hours are restricted.

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

 Solar Control Unit

Check the power outlet for the solar control unit is switched on.

 Green LED is off or red LED is flashing on Solar Monitor

If the green LED is off or the red LED is flashing on the Solar Monitor label, there may be a problem with the solar water heater operation and solar gain is not being achieved. This will result in the booster heating unit operating to provide all of the hot water required.

Switch off the electrical supply at the power outlet to the solar control unit for a few seconds, then switch on again.

If the green LED remains off or the red LED recommences to flash, then count the number of flashes and phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.

 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).

 Collector area is too small

For most installations, the number of solar collectors recommended in Rheem literature has been proven to provide the required solar energy to meet the average family needs. However, in some circumstances, it may be necessary to install an additional solar collector.

 Air in collectors (no solar gain)

It is possible under certain conditions, such as when the pipe work has been opened, that air may become trapped in the solar collectors. This will prevent the circulator from moving water around the collector circuit. The air will need to be purged from the solar collectors (refer to “Bleeding The Solar

Collectors” on page 10).

Page 18

SAVE A SERVICE CALL

 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 18.

 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.

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 6.

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, or if there has been heavy hot water usage the previous night.

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

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.

EXPANSION CONTROL VALVE RUNNING

If an expansion control valve is fitted in the cold water line to the water heater (refer to page 35) it 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.

Page 19

COLLECTOR GLASS

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 18.

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

you think?

Refer to “Not Enough Hot Water” on page 17.

 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 6.

 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.

 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 warranty.

 All packaging materials must be removed from the water heater prior to its installation. This includes the

removal of the cardboard base of the carton from the underside of the water heater.

FREEZE PROTECTION

The system has a level of freeze protection designed to guard the system against damage from freeze conditions. The system must be installed with the full length of the solar hot and solar cold pipes insulated to offer protection against freeze damage (refer to “Warning: Plumber Be Aware” on page 33). Freeze conditions occur below 6°C.

Exclusions” on page 47). Note: Warranty against freeze damage applies only to systems installed in

Australia.

INSTALLATION STANDARDS

The installation must comply with the requirements of AS/NZS 3500.4, AS/NZS 3000 and all local codes and regulatory authority requirements. In New Zealand, the installation must conform with Clause G12 of the New Zealand Building Code.

INSTALLATION – SOLAR STORAGE TANK

WATER HEATER APPLICATION

SOLAR WATER HEATER STORAGE TANK LOCATION

The solar storage tank is suitable for either outdoor or indoor installation. Whether located outdoor or indoor, the solar storage tank should be installed close to the most frequently used outlet and its position chosen with safety and service in mind.

Consideration must also be given to the position of the solar storage tank in relation to the solar collectors. There are limitations on the maximum length of the solar hot and solar cold pipes between the solar storage tank and the solar collectors. Refer to “Solar Collector

Location” on page 31 and to “Pipe Lengths” on page 32.

Clearance must be allowed for servicing of the solar storage tank. The solar storage tank must be accessible without the use of a ladder or scaffold. Make sure the temperature pressure relief valve lever is accessible and the front cover, thermostat and booster heating unit can be removed for service.

You must be able to read the information on the rating plate. If possible leave headroom of one water heater height so the anode can be inspected or replaced. Remember you may have to remove the entire solar storage tank later for servicing.

It is recommended the solar storage tank be installed at ground or floor level and must stand vertically upright. The base of the water heater is made of corrosion resistant material, and it may be placed directly in contact with the supporting surface. It is not necessary to allow for free air circulation under the base of the water heater.

Note: The water heater should not be placed in direct contact with a concrete surface that is less th an two months old and not fully cured as this may attack the metal coating of the water heater base. A moisture barrier should be used between the two surfaces in this instance.

Remember all local authorities have regulations about putting water heaters into roof spaces.

SAFE TRAY

It is a requirement of AS/NZS 3500.4 that for a new installation, a water heater be installed in a safe tray where in the event of a leak, property may otherwise be damaged. Construction, installation and draining of a safe tray must comply with the above mentioned Standard.

Page 22

INSTALLATION – SOLAR STORAGE TANK

MAINS WATER SUPPLY

Where the mains water supply pressure exceeds that shown in the table, an approved pressure limiting valve is required and should be fitted as shown in the installation diagram (refer to diagram on page 35).

TANK WATER SUPPLY

If the water heater is supplied with water from a tank supply and a minimum water supply pressure of 200 kPa at the water heater cannot be achieved, then a pressure pump system must be installed to allow the solar circuit system to operate. Care must be taken to avoid air locks. The cold water line from the supply tank should be adequately sized and fitted with a full flow gate valve or ball valve.

Page 23

INSTALLATION – SOLAR STORAGE TANK

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 and public areas such as a bathroom, ensuite or public amenities, 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 or public 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. 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 and pressure limiting valve to the solar storage tank, but it MUST BE before the non return valve. 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.

Warning: A non return valve MUST BE installed on the cold water line to the solar storage tank AFTER the cold water branch to a temperature limiting device. Due to the higher water temperatures generated under certain conditions in the solar collectors of this solar water heater, an additional effective back-flow prevention device also should be used as an extra safeguard. Valve manufacturer RMC recommends Dual Check Valve model N7150, as being suitable for this application.

If a combination isolation valve and non return valve (duo or trio valve) is installed on the cold water line to the solar water heater and the cold water line to the temperature limiting device branches off after this valve, then a second non return valve must be installed between the cold water branch and the solar storage tank. Due to the higher water temperatures generated under certain conditions in the solar collectors of this solar water heater, an effective back-flow prevention device should be used as the second non return valve as an extra safeguard. Valve manufacturer RMC recommends Dual Check Valve m odel N7150, as being suitable for this application.

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 24

INSTALLATION – SOLAR STORAGE TANK

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 24.

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 th e 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 25

INSTALLATION – SOLAR STORAGE TANK

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 full length of the solar hot and solar cold pipes between the solar storage tank and the solar collectors

MUST BE insulated. Refer to “Warning: Plumber Be Aware” on page 33.

ANODE

The correct colour coded anode for the water supply being used must be selected and fitted to the water heater for warranty to apply to the water heater cylinder (refer to “Water Supplies” on page 14 and the Anode

Selection chart on page 14). The black anode is typically fitted as standard.

If the water supply has a TDS greater than 150 mg/L and a green anode has not been changed to a black anode, or if the TDS is greater than 600 mg/L and the anode has not been changed to a blue anode, there is the possibility the anode may become overactive and hydrogen gas could accumulate in the top of the water heater during long periods of no use. In areas where this is likely to occur, the installer should instruct the householder on how to dissipate the gas safely (refer to “Caution” on page 15).

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: Damage to the cylinder as a result of saddling to the jacket will void the 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 39.

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 CONTROL UNIT

The solar control unit is designed to be mounted on the side of the solar storage tank, with its location above and offset from the solar cold water outlet. The solar control unit, supplied with a 1.8 metre power cord, requires a 240 V 50 Hz general purpose outlet (GPO) located within 1.2 metres of its installation. The GPO must have a continuous power supply originating from a circuit other than the water heater circuit. The GPO is required to be weatherproof if installed outdoors (refer to “Connections – Electrical” on page 38).

INSTALLATION – SOLAR COLLECTORS

SOLAR COLLECTOR LOCATION

Consideration must be given to the position of the solar collectors in relation to the solar storage tank. There are limitations on the maximum length of the solar hot and solar cold pipes between the solar storage tank and the solar collectors. Refer to “Solar Storage Tank Location” on page 21 and to “Pipe Lengths” on page 32.

 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.

 For optimum performance, inclination of the solar

collectors should be approximately equal to 90% of the local latitude angle. The latitude of some Australian cities are listed on page 32. Solar collectors may be installed at the roof angle for simplicity of installation and appearance, but must never be flat. If the roof angle varies by 15° from the optimum angle, the solar collectors will receive about 10% less total solar radiation.

 The collector kit is suitable for installations with an inclination of up to 30°. Where the solar collectors are

installed at inclinations greater than 30°, a With Pitch frame is necessary. Refer to your local Solar Distributor for details.

 For an installation on a roof with a pitch less than 10°, a Variable Pitch frame should be used. Refer to

your local Solar Distributor for details.

 For an installation of collectors on a pitched roof in a cyclonic or high wind area, a suitable With Pitch

frame is required. Refer to your local Solar Distributor for details.

 The installation of these solar collectors 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 (Variable Pitch frame), as defined in the Building Code of Australia, Australian / New Zealand Standard AS/NZS 1170.2:2002 and the Australian Standard AS 4055-2006, and

 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 solar water

heater installation and the roof structure is suitable to carry the full weight of the solar collector(s). If in doubt the roof structure should be suitably strengthened. Consult a structural engineer.

 Each solar collector and its fittings weighs approximately 43 kg when full of water.

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

authority requirements.

 Refer to the installation instructions supplied with the collector kit for details on the installation of the

solar collectors.

The solar hot and solar cold pipes between the solar storage tank and the solar collectors shall:

 be of bendable grade or hard drawn copper tube.

Annealed or soft copper shall not to be used.

 have a continuous fall from the solar collectors to the solar storage tank. Horizontal runs of pipe work

are acceptable and may be installed.

 not exceed the maximum recommended combined lengths as specified in the table.

For each additional 90° bend, reduce the maximum total pipe length by 0.5 metres. For each additional metre of pipe length, reduce the number of 90° bends by two. Note: One 90° elbow is equal to two 90° bends. NR – not recommended.

Notes:

 It is important not to cross connect the solar cold and solar hot pipes to the incorrect connections at the

solar collectors and at the solar storage tank.

 The solar cold pipe connects to the bottom of the solar collector and may connect to either the left or

right hand side. The solar hot pipe must connect to the top of the solar collector diagonally opposite to the solar cold pipe connection.

 The hot sensor connection is at the solar hot outlet where the solar hot pipe connects to the solar

collector.

 Refer to “Warning: Plumber – Be Aware” on page 33.

It is essential for these requirements to be followed for the system to operate correctly and efficiently. Solar pipe work which is oversized, or is too long, or does not have a continuous fall can result in a reduction in performance or the system not operating effectively.

Page 33

INSTALLATION – SOLAR COLLECTORS

WARNING: Plumber – Be Aware

 The solar hot and solar cold pipes between the solar storage tank and the solar collectors MUST BE

of copper. All compression fittings must use brass or copper olives.

 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

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 if exposed

 extend through any penetrations in the eaves, ceiling and roof

 cover valves and fittings in the solar hot and solar cold pipe work

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

Note: Failure to observe these requirements increases the risk of freeze damage.

 Plastic pipe MUST NOT be used, as it will not withstand the temperature and pressure of the water

 The highest point of the solar cold pipe and solar hot pipe must be where they connect to the solar

 A non return valve MUST BE installed on the cold water line to the solar storage tank AFTER the

 The pressure applied to the solar circuit and solar collectors during a pressure test of a direct open

circuit system MUST NOT exceed 1000 kPa, otherwise damage may result to the solar collectors. Refer to “Pressure Testing” on page 34.

Page 34

INSTALLATION – SOLAR COLLECTORS

Maximum height to collectors

The maximum height of a solar Loline installation, from the solar controller (circulator) to the top of the solar collectors, is determined by the maximum recommended total pipe length for the system and the water supply pressure.

The maximum recommended total pipe length of the solar circuit should not be exceeded and a minimum water supply pressure of 200 kPa should be available at the inlet to the system, otherwise the system performance may be reduced or the solar circuit may not be purged of air during the commissioning of the system.

Direct Open Circuit Solar – Pipe Work Installation Requirements

Pressure Testing

The solar water heater, including the collector circuit and solar collectors, 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.

It may be necessary to pressure test the collector circuit to comply with codes and regulatory authority requirements or on other occasions where the solar collectors and solar cold and solar hot pipe work are installed prior to the solar storage tank, such as on a building site.

Direct Open Collector Circuit

Warning: The pressure applied to the solar circuit and solar collectors during a pressure test of a direct open circuit system MUST NOT exceed 1000 kPa where NPT200 or HBT200 solar collectors are installed, otherwise damage may result to the solar collectors.

Direct Open System

If the solar collectors, solar pipe work and solar storage tank are installed and commissioned together, then the flooding of the collector circuit with water under mains pressure and checking for leaks during the commissioning procedure can be substituted for the pressure testing of the collector circuit.

CONNECTIONS – PLUMBING

CONNECTION SIZES

 Hot water connection: RP¾/20.

 Cold water connection: RP¾/20.

 Solar hot (from collector) connection: DN15 compression fitting.

(solar hot inlet to tank: RP¾/20)

 Solar cold (to collector) connection: DN15 compression fitting.

(solar cold outlet from tank: RP¾/20)

 Relief valve connection: RP½/15.

 Bleed valve connection: G1.0B.

All plumbing work must be carried out by a qualified person and in accordance with the Plumbing Standard AS/NZS 3500.4 and local authority requirements.

Note: The 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 supplied from the solar water heater and connected to the hot water flow and return line. Refer to “Circulated Hot Water Flow and Return System” on page 24.

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. A nonreturn valve must be fitted on the cold water supply to this water heater in compliance with Clause 5.9.1 of AS/NZS 3500.4. Due to the higher temperatures generated by solar water heaters, an additional effective back-flow prevention device also should be fitted as an extra safeguard. Valve manufacturer RMC recommends Dual Check Valve No N7150, as being suitable for this application.

An acceptable arrangement is shown in the diagram on page 35. Refer also to “Hot Water Delivery” on page 23 and to “Mains Water Supply” on page 22. The plumbing arrangements for the solar hot and solar

cold pipes are shown on page 30.

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

Page 36

CONNECTIONS – PLUMBING

This water heater has either a plastic dip tube or fitting liner in the inlet and outlet fittings (see diagram). These must be in place for the water heater to function properly. Do not remove or damage them by using heat nearby. They will be pushed into the correct position as the fitting is screwed in.

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 shipped either under the top flap of the water heater carton or behind the front cover. The temperature pressure relief valve must be fitted 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 diagram on page 27) leaving the valve outlet 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 37).

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.

EXPANSION CONTROL VALVE

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 14).

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 35). A copper drain line must be fitted to the expansion control valve (refer to "Relief Valve Drain" on page 37).

Page 37

CONNECTIONS – PLUMBING

RELIEF VALVE DRAIN

DN15 copper drain lines must be fitted to the temperature pressure relief valve and expansion control valve (if one is installed). 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.

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 easi ly 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.

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.

BLEED VALVE DRAIN

A copper drain line must be fitted to the bleed valve to carry the discharge clear of the water heater and solar control unit. Connect the drain line to the bleed valve using a disconnection union. The pipe work from the bleed valve to the drain should be as short as possible and fall all the way from the valve with no restrictions. It should have no more than three right angle bends in it. Use DN15 pipe.

The outlet of the drain line must be in such a position that flow out of the pipe can be easily seen (refer to AS/NZS 3500.4) - but arranged so water discharge will not cause injury, damage, nuisance or splashing. The water discharged may be of a high temperature under certain conditions. The drain line must be fully insulated with closed cell polymer insulation or similar (minimum thickness 13 mm). The insulation must be weatherproof and UV resistant if exposed.

Page 38

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 local 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.

The power consumption of the water heater is:

The water heater will only operate on a sine wave at 50 Hz. Devices generating a square wave cannot be used to supply power to the water heater.

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.

SOLAR CONTROL UNIT

The solar control unit, supplied with a 1.8 metre power cord, requires a switched 240 V AC 50 Hz general purpose outlet (GPO) to be located within 1.2 metres of the installation. The GPO must have a continuous power supply originating from a circuit other than the water heater circuit. The GPO is required to be weatherproof if installed outdoors.

Page 39

CONNECTIONS – ELECTRICAL

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.

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

The timer control switch 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,

 for a period when power will be available to the timer.

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.

TO FILL AND TURN ON THE WATER HEATER

The power supply to the solar storage tank and solar control unit 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 cold water isolation valve fully on the cold water line to the water heater.

Air will be forced out of the taps.

 Close each tap as water flows freely from it.

 Check the pipe work for leaks.

 Bleed the solar collectors (refer to “Bleeding the Solar Collectors” on page 42).

 Plug in the solar control unit at the power outlet and switch on the electrical supply.

The power outlet must be switched on for the solar control unit to operate and solar gain to be achieved.

Note: When the electrical supply is switched on to the solar control unit at start up:

 If there is no solar gain, the circulator will not activate and the green LED will emit a slow pulse.

The slow pulse indicates the circulator is not activated and the power to the solar control unit has been on for less than 48 hours.

 If there is solar gain, the circulator activates and the green LED will emit a series of three (3)

flashes.

The three (3) flashes indicate the circulator is operating and power to the solar control unit has been on for less than 48 hours.

 The circulator will operate at full speed for approximately fifteen (15) seconds. If the red LED is

emitting a rapid pulse, the circulator may operate at full speed for up to ten (10) minutes.

After fifteen (15) seconds or after the red LED has extinguished, the solar controller will commence to pulse the circulator to control the flow rate through the collector circuit and achieve a constant temperature rise across the collector(s). It is normal operation for the circulator to experience a pulsing effect.

 The red LED may emit a rapid pulse for a short period.

This indicates a temperature difference between the hot sensor and cold sensor of greater than 40°C and does not represent a fault code. This is the result of a build-up of heat and increase in water temperature in the collector prior to the switching on of the electrical supply to the solar control unit.

The rapid pulsing of the red LED will cease as the water circulates and the heat is dissipated. This should be within four (4) to five (5) minutes of start up, but may take up to ten (10) minutes.

If the red LED does continue to emit a rapid pulse for longer than ten (10) minutes, this may indicate water is not circulating through the collectors and solar circuit:

 switch off the electrical supply at the power outlet to the solar control unit

 repeat the procedure to bleed the solar collectors

 switch on the electrical supply at the power outlet to the solar control unit

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

 Set the timer if one is installed (refer to “Booster Control” on page 39).

Page 42

COMMISSIONING

Explain to the householder or a responsible officer the functions and operation of the solar 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 a responsible officer.

BLEEDING THE SOLAR COLLECTORS

Upon completion of the installation, it is necessary to purge the air from the collector circuit.

To purge air from the collector circuit:

 Ensure the water heater is full of water and all of the

hot taps are turned off.

 Using a flat blade screwdriver, open the bleed valve

fitted adjacent to the solar hot water inlet of the solar storage tank (see diagram).

 The mains pressure will force water to flow from the

tank and through the pipe work, forcing air from the collector circuit through the bleed valve. This is evidenced by spurting of water from the drain line connected to the bleed valve.

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

 Close the bleed valve when water runs freely from the

drain line.

TO TURN OFF THE WATER HEATER

If it is necessary to turn off the water heater on completion of the installation, such as on a building site or where the premises is vacant, then:

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

 Switch off the electrical supply at the power outlet to the solar control unit (refer to note below).

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

Notes:

 The freeze protection system will be rendered inoperable if electrical power is not available at the solar

control unit. Damage caused by freezing due to no power at the solar control unit is not covered by warranty.

 If there is a risk of freezing, then it is necessary to drain the solar collectors and solar collectors and

solar flow and return pipe work (refer to “Draining the Solar Collectors” on page 44).

 Refer to “Warranty Exclusions” on page 47.

DIAGNOSTIC FEATURES OF THE SOLAR CONTROLLER

A solar monitor is located on the side of the solar control unit and houses a green and a red LED.

The green LED, marked “Solar”, indicates the current operational mode of the solar water heater and the red LED, marked “Attention”, indicates a fault mode.

The green LED will emit either a constant glow or a series of flashes, with a 2 second interval between each series.

The red LED will emit a series of flashes, with a 2 second interval between each series, only if there is a particular fault condition with the system.

Note: During periods of high solar radiation and if the circulator activates after having been off, such as during start up, it is possible the red LED may emit a rapid pulse for a period of up to ten (10) minutes. This does not indicate a fault. Refer to “To Fill And Turn On The Water Heater” on page 41 for the possible green and red LED flashing sequence during start up procedure.

Page 44

DRAINING THE SOLAR COLLECTORS

To drain the solar collectors and the solar hot and solar cold pipe:

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

collector(s).

This will assist in the transfer of any high temperature water in the solar collector(s) to the solar storage tank.

 Close the hot water tap.

Warning: Exercise care, as water discharged from the solar collectors may be of a very high temperature.

 Turn off the water heater (refer to “To Turn Off The Water Heater” on page 42).

 Using a flat bladed screw driver, open the bleed valve fitted adjacent to the solar hot water inlet of the

solar storage tank (refer to diagram on page 42).

 Undo the compression fitting at the top of the circulator (located at the side of the solar control unit) and

disconnect the solar cold pipe.

Water will now drain from the solar collectors and the solar hot and solar cold pipes.

 When water stops flowing from the solar hot and solar cold pipes, reconnect the solar cold pipe to the

circulator and tighten the compression fitting.

 Close the bleed valve.

DRAINING THE WATER HEATER

To drain the water heater:

 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 high temperature water in the solar collector(s) to the solar storage tank.

 Close the hot water tap.

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

 Turn off the water heater (refer to “To Turn Off The Water Heater” on page 42).

 Operate the relief valve release lever - do not let the lever snap back or you will damage the valve seat.

Operating the lever will release the pressure in the water heater.

 Undo the union at the cold water inlet to the 4 way tee 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 water heater and allow the water to drain through the hose.
