IMPORTANT INFORMATION & WARNINGS
OPERATION PRINCIPLE
This system is designed to have the solar collectors on the roof and the storage cylinder installed at ground or floor
level.Electric and Gas boosted models are available. The system comprises a hot water storage cylinder, solar
collectors, pump circulation system solar control unit and temperature sensors. The solar control unit ensures
water circulates between the solar collectors and the storage cylinder to transfer heat from the solar collectors to
the water in the cylinder if enough heat is available from the sun.
Supplementary heating is provided if insufficient heat is available from sun (such as during cloudy or rainy weather
or during winter months) either via an electr ic heating e l ement(s) located inside the stora ge cylinder or via a on inline Gas booster located external to the storage cylinder. The following diagrams illustrates the Split Solar Hot
Water System set up for both the Electric and Gas boost.

IMPORTANT INFORMATION & WARNINGS
SAFETY DEVICES
The water heating system is supplied with various safety devices including temperature sensors, overheat sensors
and switches and a Pressure & Temperature Relief (PTR) valve. These devices must not be tampered with or
removed. The water heating system must not be operated unless each of these devices is fitted and is in working
order.
EXCESSIVE DISCHARGE FROM SAFETY DEVICES
Pressure & Temperature Relief (PTR) Valve
It is normal and desirable that this valve allows a small qua ntity of water to be discharged during the heating cycle.
If it discharges more than a bucket of water during a 24 hour period or discharges continuously there may be
another problem.
If the valve dribbles continuously, try easing the valve gear for a few seconds as described above. This may
dislodge any foreign matter and alleviate the problem.
If the valve discharges at high flows, especially at night, it may be as a result of the water pressure exceeding the
design pressure of the water heater. Ask your installer to fit a Pressure Limiting Valve (PLV).
Expansion Control Valve (ECV) - if fitted
It is normal and desirable that this valve allows a small qua ntity of water to be discharged during the heating cycle.
If it discharges more than a bucket of water during a 24 hour period or discharges continuously there may be
another problem.
If the valve leaks continuously, try easing the valve gear for a few seconds. This may dislodge any foreign matter
and alleviate the problem. If this does not alleviate the problem contact Rinnai.
Operate the easing gear regularly to remove any lime deposits and to verify that it is not blocked.
DO NOT tamper with or remove safety devices.
DO NOT operate the water heater unless all safety devices are fitted and in working order.
DO NOT block or seal the PTR Valve and drain pipe.
Pressure & Temperature Relief (PTR) Valve
This valve is located near the top of the water heater
and is essential for safe operation. It is normal for the
valve to release a small quantity of water through the
drain line during heating.
However, continuous leakage of water from the
valve and its drain line may indicate a problem with
the water heater.
Never block the outlet of the PTR valve or it’s drain line for any reason. The easing gear must be
operated at least every 6 months to remove lime dep osits a nd v erify that it is not bloc ked . Failure
to do this may result in the water heater failing.
If the valve does not discharge water when the easing gear lever is opened, o r does not se al again
when the easing gear is closed, attendance by an authorised person must be arranged without
delay. The PTR valve is not serviceable.
NEVER replace the PTR valve with one which has a higher pressure rating than is specified for your
water heater.
WARNING
Twist cap until water
flows from drain line
Lift lever until water
flows from drain line
(Lower lever gently!)

WARNING
Rinnai Australia 6 Solar Split Systems Operating / Installation Manual - Version 8 18/10/10
IMPORTANT INFORMATION & WARNINGS
Gas boosted models
• Do not touch the flue outlet or do not insert any objects into the flue outlet.
• Keep flammable materials, spray cans, fuel containers, trees, shrubs and pool
chemicals etc. well clear of the flue outlet.
• Do not use the gas types other than those designated on the data plate. For
example, do not use Propane/Butane gas mixtures on appliances marked Propane
Gas.
• Do not use Propane gas on appliances marked as Natural gas and vice versa.
Hydrogen Gas
In the case of systems using a vitreous enamelled lined cylinder, if the hot water unit is not used for two weeks or
more, a quantity of hydrogen gas, which is highly flammable, may accumul ate in the water heater. To dissipate this
safety, it is recommended that a non electrically operated hot tap be turned on for two minutes at a sink, basin, or
bath, but not a dishwasher or other appliance. during this proced ure there must be no smoking, open flame or any
electrical appliance operating nearby. If hydrogen is discharged through the tap, it will probably make a sound like
air escaping.
WATER TEMPERATURE
The solar control unit and pump ensure water circulates be tween the solar co llectors and storage cylin der until the
water at the base of the cylinder reaches approximately 65°C. Under these conditions water at the hot outlet may
exceed 85°C. During periods of low solar gain supplementary heating occurs to a minimum of 60°C as required.
TURNING ‘OFF’ THE WATER HEATING SYSTEM
If you plan to be away for only a few nights, we suggest you leave the water heating system switched on. If it is
necessary to switch off the water heater, do so as outlined below:
Electric Boosted systems
• Switch off the electric supply to the supplementary hea ting element. The switch is usually marked and
located in the electricity meter box of the dwelling.
• Switch off the electric supply to the solar controller and pump.
Gas Boosted systems
• Switch off the electric supply to the gas booster.
• Switch off the electric supply to the solar controller and pump.
TURNING ‘ON’ THE WATER HEATING SYSTEM
Electric Boosted system
• Switch on the electric supply to the suppleme ntary heating element(s). The switch is usu ally marked and
located in the electricity meter box of the dwelling.
• Switch on the electric supply to the solar controller pump. Electric and solar water heating will now occur as
required. It may take a number of hours before hot water is available.
Gas Boosted systems
• Switch on the electric supply to the gas booster.
• Switch on the electric supply to the solar controller and pump. Solar water heating will now occur. Hot
water is available immediately from the gas booster when hot water tap is opened, irrespective of solar
heat gain.
To meet Australian regulatory requirements, supplementary heating temperature settings
must be at least 60°C.
HOT!

WATER QUALITY
The water quality of most public supplies is suitable for the water hea ting system. The water quality from bore wells
is generally unsuitable for the water heating system. Refer to separate 'Warranty Terms and Conditions' document
for water quality parameters and how they affect the warranty conditions. If in doubt about the water quality, have
it checked against the parameters listed in the warranty conditions. The system is not suitable as a pool or spa
heater.
DRAINING AND FILLING THE WATER HEATING SYSTEM
• Draining or filling normally occur only during installation or servicing and must be carried out by an
authorised person.
MAINTENANCE AND REGULAR CARE
Operate the easing gear of the PTR as described under “SAFETY DEVICES” on page 5.
The overflow tray (supplied by installer) and drain underneath the storage cylinder (if fitted) should be periodically
checked to ensure there are no blockages.
SERVICING AND REPAIR
Our Servicing network personnel are fully trained and equipped to give the best service on your appliance. If your
appliance needs service, ring one of the service contact numbers on the back of this booklet.
It is recommended that the system be serviced at least every 5 years.
The pressure and temperature relief valve and expansion control valve must be checked for performance or
replaced by an authorised person at intervals not exceeding 5 years or more frequently in areas where the water
is classified as scaling water (refer to ‘Warranty Terms and Conditions’ document - ‘Water Quality’).
It is recommended that the sacrificial anode fitted to Sunmaster cylinders be inspected very 5 years or more
frequently in areas where there is a high incidence of water deposits. This does not apply to Rinnai Prestige
cylinders. Anodes suited to hard and soft water, are available from Rinnai.
If the electric conduit, power supply cord or plug to the water heater is damaged, they must be replaced by an
authorised person in order to avoid a hazard. The power supply cord and plug (if fitted) must be replaced by a
genuine replacement part available from Rinnai.

Electric boosted Systems:
Check to ensure the electric isolating switch(es) at the switchboard (usua lly marked
"Hot water" or "water heater") is switched 'ON'.
Check to ensure that the electric fuses for hot water at the switchboard are intact.
Gas Boosted Systems:
Check to ensure the power cord of the gas booster is plugge d in and the power point
switched 'ON'.
Check gas is available and turned ON'.
Close the hot tap and wait for 10 seconds and open it again. The hot tap must be
opened enough to ensure that the flow rate is not less than 2.4

Refer to your plumber to ensure the gas line has been purged of air after ins tallation.
Excessive hot water
consumption
Electric Boosted Systems:
If the water goes cold, are you using more hot water than you think? Often end
users are surprised at the amount of hot water used, especially when showering. If
the amount of hot water used during the day exceeds the storage capacity of the
cylinder, it is likely that there will be insufficient hot water. Has your plumber install
water saving fixtures and/or flow control or pressure limiting valves to reduce
consumption.
Gas Boosted Systems:
Insufficient flow may occur if multiple outlets are in use at the same time and exceed
the rated flow capacity of the gas boost er. If so, reduce the number of outlets in use.
Have your plumber install water saving fixtures and/or flow control or pressure
limiting valves to reduce consumption.
Check correct size gas booster is fitted.
Incorrect Solar system size Do you have the correct system size and configuration for your requirements? Refer
to Rinnai literature for information.

If the valve dribbles continuously, try easing the valve gear for a few seconds as
described under 'Regular Care'. This may dislodge any foreign matter and alleviate
the problem.
If the valve discharges at high flows, especially at night, it may be as a result of the
water pressure exceeding the design pressure of the water heater. Ask your installer
to fit a Pressure Limiting Valve (PLV).
• Never replace the PTR valve with one which has a higher pressure rating than is specified for your water heater.
• If the valve discharges hot water at high flows, (dumps) there may be a serious problem. Switch off the power
supply in the meter box (the switch marked ‘WATER HEATER’ or ‘HOT WATER’) or the isolating switch installed
near the water heater and contact Rinnai.

Booster element Thermostat Settings Electric Boosted Systems:
The end user can check the temperature of hot water delivered with a
thermometer placed under the closest non tempered outlet (usually the kitchen
sink).
CAUTION: Take care to avoid scalding. This test should be done early in
the morning after overnight electrical boosting before any hot water is
used. The temperature of the water delivered should be at least 55° C
(allowing for heat losses in pipe work).
If this is not the case or the temperature needs to be increased contact Rinnai.
The thermostat settings of the heatin g element thermo stat can also be co nfirmed
directly by a qualified person as described under 'hot water storage & delivery
temperature'. The settings can be increased if required. Contact Rinnai.
Gas Boosted Systems:
The delivery temperature of gas boosted systems is normally 60 or 65°C. Iff
temperatures are higher than this, the flow of water through the gas booster will
reduce and may result in insufficient flow rate.
The end user can check the temperature of hot water delivered with a
thermometer placed under the closest outlet (usually the kitchen sink).
CAUTION: Take care to avoid scalding. If the temperature is higher than
65°C the gas booster may be preset incorrectly. Contact Rinnai.
No Water from the hot tap Restriction in the hot tap or failure of the cold water
supply to the water heater.
Check for water flow at the other taps and that the cold water isolation is fully
open.

Insufficient Sunlight - Collectors shaded Ensure the trees or other objects are not shading onto the collecto r surface (Trim
the trees or relocate the solar collector if the obstruction is permanent).
Make sure the glass on the collector is not dirty.
High electricity or gas bill Excessive hot water consumption See entry under 'Insufficient hot water'.
Solar Control unit switched off If the solar control unit is switched off there will be no solar pre-heating of water
resulting in the water being heated entirely by electricity or gas' bo osting'. Check
the power outlet for the solar contr ol unit is switched on.
T emperature and pressure relief valve / Expansion
Control valve discharging water continuously
See entry under 'Insufficient hot water'.
Lack of solar gain Reduced sunlight:
Reduced sunlight due to overcast weather in summer or low solar contribution in
winter will result in an increased dependence on electricity or gas boosting.
Higher electricity or gas bills under these conditions, especially in winter, are
normal.
Collectors shaded:
If the solar collectors are shaded by trees or other objects, or the glass is dirty,
the effectiveness of the collectors is greatly reduced. Arrange for trimming of the
trees or relocation of the solar collectors if the obstruction is permanent. Arrang e
for cleaning of the collector glass.
Solar collectors incorrectly positioned
Check that positioning and alignment of solar collectors is in accordan ce with t he
section 'Location and alignment of solar collectors'.
WARNING: Persons working from elevated surfaces such as roofs must be
adequately trained an qualified in accordance with local OH&S requirements.
High Electricity Tariffs (electric boosted systems only) Electric Boosted Systems
The electricity tariff will determine the running costs of the system. It is important
the end user is aware of the applicable tariffs. Contact your electricity supplier to
confirm what these tariffs are.
Little or no water circulation in the solar 'flow and
return' loop
There are numerous causes of little or no circulation in the solar 'flow and return
circuit the circulation of water through the collectors. These causes must be
investigated by a qualified person. Contact Rinnai.
Water flow fluctuations One or more hot taps opened at the same time More than one or two hot taps in use at the same time may cause a decrease in
the hot water flow from the taps.
Is there more than one or two hot taps open, or are appliances such as a
dishwasher or washing machine, in use at the same time?
Ensure only one or two hot taps are on at one time.
Check the flow of the water from one tap, eg. the shower. The shower should be
adjusted so the hot tap is fully open.
Water Hammer Hot and cold water plumbing in the premises Have a plumber check clipping of hot and cold water pipework and install a
pressure limiting valve and water hammer arrestor as required.

SPECIFICATIONS FOR SYSTEMS
GENERAL
Split solar hot water systems are specified according to the grade of storage cylinder material, cylinder
capacity, number of solar collectors and boost type and capacity. Boost capacity for gas boosted
system depends on the gas booster model selected. Boost capacity for electrically boosted systems
depends on the power rating of electric heating elements and whether one or two electric heating
elements are fitted.
SYSTEM SPECIFICATIONS AND DIMENSIONS
Specifications and principal dimensions for the various systems and components are shown below.
FLOW CONTROL VALVE
A flow control valve is fitted to the pump and cont ro ller asse m bly .
It’s purpose is to allow the water flow rate through the collector collectors and storage cylinder to be
controlled to optimise the performance of the system.
DIFFERENTIAL TEMPERATURE CONTROLLER
The primary task of the differential temperature controller is to control the operation of the pump to
optimize solar energy collection. This task is performed by measuring the temperature differential
between the hot sensor and the cold sensor. When the differential exceeds 9°C the pump is activated
and water passes through the collectors collecting solar energy. When the d ifferentia l falls below 5°C
the pump is shut down.
A secondary task of the controller is to stop energy collection when the cylinder is full of hot water.
This is referred to as no load protection and the pump is shut down if the temperat ure of the water
going to the collectors exceeds 65°C. At such a temperature in the base of the cylinder, the
temperature of water in the top of the cylinder is expected to be about 85°C.

LOCATION - GENERAL INFORMATION
All system components must be in an accessible location. The storage cylinder must be accessible
without the use of a ladder or scaffold. Sufficient clearances shall allow access to, and removal of,
all serviceable parts. Ensure the PTR valve, pump kit, drain lines and thermostat and elements for
electric systems have sufficient clearances and are accessible for service and removal. The
information on any data plates must also be readable. In the case of vitreous enamel lined cylinder s,
leave a clearance of the height of one storage cylinder above the cylinder being installed so the
sacrificial anode can be inspected and replaced. This does not apply to stainless steel cylinders.
Select suitable areas of roof on which to install the solar collectors as close as practicable to the
cylinder. Ensure that the area is even and without cracked or damaged tiles. Collectors should be
positioned for optimum solar benefit. Refer to the section 'INSTALLATION OF SOLAR
COLLECTORS' for more information.
The solar pump kit and gas booster heater require an AC 240V power supply. A wea therproof 240V,
10A earthed power point must therefore be pr ovided a djacent to thes e. All electrically boosted solar
hot water heating elements must be connected to an independent, fused, AC 240V 50 Hz power
supply with an isolating switch installed at the switch board.
STORAGE CYLINDER LOCATION
The storage cylinder should be placed as close as pr acticable to the mo st frequently used ho t wate r
outlet point or points to minimise the delay time for hot water delivery. This will usually be the kitchen
tap.
The solar storage cylinders have an ingress protection rating of IPX4 making them suitable for
internal or external installation. Rinnai 'external' gas boosters are suitable for external installation
only.
Storage cylinders must be installed in freestanding mode on a level and stable base. For external
installations, storage cylinders should be mounted on a concrete base at least 50mm thick or on well
seasoned, evenly spread hardwood slats with a thickness of at least 25mm. Where prop erty damage
can occur, storage cylinders should be installed with an approved safe tray (overflow tray).
Ensure the cylinder does not stand on wet surfaces.
Installation and commissioning must be performed by authorised persons.
Solar systems must be installed in accordance with these instructions and all
regulatory requirements which exist in your area including those in relation to
manual lifting, working at heights and on roofs. Applicable publications and
regulations may include:
• AS 5601 Gas Installations
• AS/NZS 3500 National Plumbing and Drainage
• AS/NZS 3000 Wiring rules
• Building Codes of Australia (BCA)
• Local Occupational Health and Safety (OH&S) regulations
This appliance is not suitable for use as a domestic spa pool or swimming pool
heater.
Solar collectors are heavy and bulky items and are usually positioned on the
roofs of buildings. Australian State and Territories have a principal Occupationa l
Health and Safety (OH&S) Act which contains requirements relating to the
handling of large, bulky or awkward items and the prevention of falls from
elevated surfaces. Persons installing solar collectors must be aware of their
responsibilities and be adequately trained and qualified, in accordance with
local OH&S requirements.

GAS BOOSTER LOCATION AND MOUNTING (where applicable)
The gas booster is designed for 'Outdoor' Installation only. As such, it must be located in an above
ground open air situation with natural ventilation, without stagnant areas, where gas leakage and
products of combustion are rapidly dispersed by wind and natural convection.
The maximum recommended combined lengths of the solar flow and return pipes are as follows:
WATER SUPPLY
The minimum and maximum water pressures for the various systems are listed in Table 2. Approved
pressure limiting valves may be required if the 'Maximum' rated water supply pressures are
exceeded. For gas boosted systems to achieve the rated flow through the outlet of the continuous
flow water heater, the minimum water supply pressures must be supplied. The systems will operate
at lower pressures but the rated flow will not be achieved.
Water chemistry and impurity limits are detailed in the separate Warranty document. Most
metropolitan water supplies fall within these requirements. If you are unsure about water quality,
contact your water authority. If sludge or foreign matter is present in the water supply, a suitable filter
should be incorporated in the water supply to the storage cylinder.
HOT WATER DELIVERY TEMPERATURE
Local regulations and/or the requirements of AS/NZS3500.4 must be considered regarding the
temperature limitations of hot water supplied to areas used primarily for personal hygiene. The
temperature of water to these areas is limited to 45°C for early childhood centres, primary and
secondary schools and nursing homes or similar facilities for young, aged, sick or people with
disabilities and 50°C for all other buildings. To comply with these requirements, a temperature
limiting device, such as a thermostatic mixing or tempering valve, will be required on all solar hot
water systems as detailed in Figures 9 and 10.
WATER PIPES
All hot water pipework should be insulated with sealed Polyethylene foamed or equivalent insulation
to optimise performance and energy efficiency. Such insulation may also be mandatory under local
regulations. With the exception of solar collector flow and return pipes, water pipe sizing should be
performed in accordance with AS/NZS 3500.
The collector flow and return pipes should be a minimum of 15 mm copper tube.
Plastic pipe must not be used. Plastic pipe is not suited to the high water
temperatures and pressures that may occur in the collector flow and return
system.
