WARNING: Plumber – Be Aware
Use copper pipe ONLY. Plastic pipe MUST NOT be used.
It is a requirement of a solar water heater installation that all pipe work be in
copper and not plastic, due to the effects of high water temperatures.
This water heater must be installed and serviced by a qualified person.
Please leave this guide with the householder.
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 closed circuit fluid generated by the solar collectors under
stagnation conditions
The specification of the chosen insulation material should be checked with the insulation
manufacturer prior to installation as different materials may vary in temperature tolerance.

be at least 13 mm thick, however thicker insulation may be required to comply with the
requirements of AS/NZS 3500.4

be weatherproof and UV resistant 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.
The insulation will offer corrosion protection to a metal roof against water runoff over the copper pipe,
assist in avoiding accidental contact with the solar pipe work as high temperature closed circuit fluid
can flow from the solar collectors to the solar storage tank and also reduce pipe heat losses.
There MUST BE a continuous fall of a minimum 5° (1 in 10 grade) in the pipe work between the
solar collector and solar storage tank for efficient and effective drain back to occur. The highest point
of the solar cold pipe and solar hot pipe must be where they connect to the solar collector.
The system has NO WARRANTY for freeze damage if there is not a continuous fall in the solar hot
and solar cold pipes, or they are not insulated in accordance with the installation instructions, or the
closed circuit fluid has been incorrectly mixed.
The insulated copper pipe work:

should be fixed at suitable locations to prevent or reduce the possibility of noise from water
hammer and vibration from occurring

is not to be placed or installed in contact with plastic pipe work.
Likewise, plastic pipe work is not to be placed or installed in contact with the insulated copper
pipe work after the solar circuit is installed.
Plastic pipe MUST NOT be used, as it will not withstand the temperature of the closed circuit fluid
generated by the solar collectors under stagnation conditions. The solar collectors can generate
extremely high closed circuit fluid temperatures of up to 150°C. Plastic pipe cannot withstand these
temperatures and MUST NOT be used. Failure of plastic pipe can lead to the release of high
temperature closed circuit fluid and cause severe water damage and flooding.
The pressure applied to the solar circuit and solar collectors during a pressure test of an indirect
closed circuit system MUST NOT exceed 200 kPa, otherwise damage may result to the solar
collectors. Refer to “Pressure Testing” on page 29.

ABOUT YOUR WATER HEATER
WATER HEATER APPLICATION
This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable
water. Its use in an application other than this may shorten its life.
MODEL TYPE
®
Your Rheem Premier Loline solar water heater is designed for the solar collectors to be roof mounted and
the solar storage tank to be installed at ground or floor level. The solar storage tank is suitable for installation
either outdoor or indoor and with either Rheem S200 or T200 solar collectors. The system is suitable for
installation in areas subject to frost or freeze conditions. Freeze conditions occur below 6°C.
This water heater is designed to be installed with an in-series booster. For information relating to the function
and operation of the in-series booster, refer to the Owners Guide and Installation Instructions supplied with
the water heater.
SOLAR OPERATION
The Rheem Premier Loline solar water heater has its vitreous enamel lined solar storage tank installed at
ground or floor level, remotely from the solar collectors. This water heater is an indirect solar hot water
system with a heat exchanger in the solar storage tank.
The heat exchanger is filled with closed circuit fluid and is connected to the solar collectors forming a closed
circuit. The closed circuit fluid is a solution of a blue, non-toxic food grade propylene glycol concentrate
mixed with water. The closed circuit concentrate is used to lower the freezing temperature of the closed
circuit fluid and provides protection against freezing.
As the sun heats the solar collectors, the increase in temperature activates
the pump. The pump switches on whenever the solar collectors are hotter
than the water in the tank. The pump moves the closed circuit fluid from
the solar storage tank heat exchanger through an insulated copper pipe to
the solar collectors to be heated by the sun‟s energy and then back to the
heat exchanger. Heat transfers from the closed circuit fluid in the heat
exchanger to the water stored in the solar storage tank.
This process continues while solar energy is available and until the water
in the solar storage tank reaches a temperature of approximately 75°C.
The pump is then deactivated and the closed circuit fluid in the solar
collectors and solar pipe work drains back into the heat exchanger in the
solar storage tank.
The closed circuit provides protection to the solar collectors and solar
circuit in harsh water areas. The drain back principle provides protection to
the system in freezing conditions.
Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
BOOSTER WATER HEATER OPERATION
Water stored in the solar storage tank passes through the in-series booster when a hot tap is opened. The
in-series booster is for heating the water at times of low solar energy gain, such as during cloudy or rainy
weather, or during colder months.
Solar heated water can reach temperatures up to 75°C in the solar storage tank. When the solar heated
water temperature is above the temperature setting of the in-series booster, the booster will not boost the
water temperature.
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 19, a pressure limiting valve must be
fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
4
ABOUT YOUR WATER HEATER
HOW HOT SHOULD THE WATER BE?
The solar control unit will circulate the closed circuit fluid through the
solar collectors until a temperature of approximately 75°C is
reached in the solar storage tank. During periods of low solar energy
gain, the in-series booster will boost the water temperature
automatically to its temperature setting when required.
Note: AS 3498 requires that a water heater provides the means to
inhibit the growth of Legionella bacteria in potable water. If this
water heater is installed with an continuous flow in-series 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.
typical maximum

bathrooms and ensuites
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.
Warning: Temperature controllers must not be fitted to the in-series booster as part of a solar water
heater system because water at a temperature much higher than the controller setting can be delivered.
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.
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 covers will expose 240 V wiring. They must only be removed
by a qualified person. The power lead from the water heater 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 closed circuit fluid 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.
Should the water from the water heater appear blue or if blue closed circuit fluid is noticed around the base
of the water heater, this indicates a leak of the closed circuit fluid from the heat exchanger. The closed circuit
fluid is non-toxic and not hazardous to health. Phone Rheem Service or their nearest Accredited Service
Agent to arrange for an inspection.

ABOUT YOUR WATER HEATER
SAFETY
This water heater is supplied with temperature sensors, a pressure relief valve 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.
If the power supply cord or plug to the solar storage tank is damaged, it must be replaced by a qualified
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 Rheem warranty may not cover faults if relief valves or other safety devices are tampered with or
if the installation is not in accordance with these instructions.
PRECAUTIONS
Where damage to property can occur in the event of the water heater leaking, the water heater must be
installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4
and all local codes and regulatory authority requirements.
The water heater must be maintained in accordance with the Owner‟s Guide and Installation Instructions.
Refer to “Regular Care” on page 9 and to “Anode Inspection and Replacement” on page 12.
If this water heater is to be used where an uninterrupted hot water supply is necessary for your application or
business you should ensure that you have back up redundancy within the hot water system design. This
should ensure the continuity of hot water supply in the event that this water heater were to become
inoperable for any reason. We recommend you seek advice from your plumber or specifier about your needs
and building back up redundancy into your hot water supply system.
GOING ON HOLIDAYS
It is not necessary to switch off the electrical supply at the power outlet to the water heater if you are going
away. However, if it is necessary to switch off the power to the water heater, refer to “To Turn Off The Water
Heater” on page 8.
PIPE WORK AND INSULATION
The solar hot and solar cold pipes between the solar storage tank and the solar collectors and the pipe work
between the solar storage tank and a remote in-series water heater 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 temperatures of the fluid 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.
The insulation will offer corrosion protection to a metal roof against water runoff over the copper pipe, assist
in avoiding accidental contact with the solar pipe work as high temperature closed circuit fluid can flow from
the solar collectors to the solar storage tank and also reduce pipe heat losses.
There must be a continuous fall in the pipe work from the solar collector to the solar storage tank. The
continuous fall is essential to assist in the drain back function of the solar system.
Plastic pipe MUST NOT be used, as it will not withstand the temperature of the closed circuit fluid generated
by the solar collector under certain conditions (refer to Warning on page 27).

ABOUT YOUR WATER HEATER
FREEZE PROTECTION
The solar circuit must be installed with a continuous fall of a minimum 5° (1 in 10 grade) in the pipe work
from the solar collector to the solar storage tank, with the full length of the solar hot and solar cold pipes
insulated and the system charged with correctly mixed closed circuit fluid to offer protection against freeze
damage. The system has NO WARRANTY for freeze damage if there is not a continuous fall in the solar hot
and solar cold pipes, or they are not insulated in accordance with the installation instructions, or the closed
circuit fluid has been incorrectly mixed (refer to “Terms of the Rheem Warranty” on page 55 and to “Pipe
Work and Insulation” on page 6).
The anti freeze control of the solar circuit is designed so there is no closed circuit fluid in the solar collector or
solar cold and solar hot pipes when the pump is off.
Notes:
Pipe work to and from the water heater must be adequately insulated to prevent freezing.
The water heater is not suitable for installation in areas where the ambient temperature falls below
-20ºC.
Refer to “Terms of the Rheem Warranty” on page 55.
RAIN WATER TANK
If the solar collectors and solar pipe work are installed on a section of roof which is part of a rain water runoff
collection system, then it is recommended this section of roof and its gutter be isolated from the rain water
collection system. The gutter should be isolated to a width greater than the solar collectors and pipe work
and must have suitable drainage. This is to ensure in the event of a leak from the solar collectors or pipe
work, a rainwater tank cannot be contaminated with closed circuit fluid.
The closed circuit fluid contains food grade additives (rust inhibitor and anti-freeze agent), is non-toxic and is
harmless to the environment. However, if it enters a rain water tank, it can kill off microscopic algae which
are typically present in the water causing an unpleasant odour to develop and resulting in the rain water tank
having to be drained and cleaned.
SOLAR MONITOR
The solar storage tank incorporates a solar monitor. The solar monitor is located on the lower front cover and
houses both 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
solid green

Call for service
If the power supply to the water heater is on and the green LED is off or the red LED is flashing, this
indicates there is a fault with the water heater. The red LED may emit up to six flashes in each series of
flashes. Count the number of flashes and phone Rheem Service or their nearest Accredited Service Agent to
arrange for an inspection.

REGULAR CARE
MINOR SIX MONTH MAINTENANCE
It is recommended minor maintenance be performed every six months by the dwelling occupant.
The minor maintenance includes:
Operate the easing lever on the temperature pressure relief valve. It is very important you raise and
lower the lever gently. Refer to “Temperature Pressure Relief Valve” on page 10.
Warning: Exercise care to avoid any splashing of water, as water discharged from the drain line will
be hot. Stand clear of the drain line‟s point of discharge when operating the valve‟s lever.
Operate the easing lever on the expansion control valve (if fitted). It is very important you raise and
lower the lever gently. Refer to “Expansion Control Valve” on page 10.
Check the drain line from the safe tray (if one is installed) is not blocked.
If this solar storage tank is installed with a remote in-series Rheem continuous flow gas booster, it is
recommended minor maintenance be performed every six months on the gas booster by the dwelling
occupant. Another type of in-series booster may have its own recommended minor maintenance schedule.
Refer to the Owner‟s Guide and Installation Instructions supplied with the booster water heater for
information regarding its recommended maintenance.
MAJOR FIVE YEAR SERVICE
It is recommended a major five year service be conducted on the water heater.
Warning: Servicing of a water heater must only be carried out by a qualified person. Phone Rheem
Service or their nearest Accredited Service Agent.
Note: The five year service and routine replacement of any components, such as the anodes and relief
valves, are not included in the Rheem warranty. A charge will be made for this work. Only genuine
replacement parts should be used on this water heater.
The major service includes the following actions:
Replace the temperature pressure relief valve.
Inspect and flush the expansion control valve (if fitted). If required, replace the valve.
Inspect and if required, replace the anodes.
If an anode is not replaced, it should be replaced within three years of this service (refer to “Anode

ABOUT YOUR WATER HEATER
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 15).
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.
Warning: Failure to do this may result in the water heater
cylinder failing.
Warning: Exercise care to avoid any splashing of water, as
water discharged from the drain line will be hot. Stand clear of the
drain line‟s point of discharge when operating the valve‟s lever.
If water does not flow freely from the drain line when the lever is
lifted, then the water heater must be checked. Phone Rheem
Service or their nearest Accredited Service Agent to arrange for an
inspection.
The temperature pressure relief valve should be 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 11).

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.
10
WATER SUPPLIES
This water heater must be installed in accordance with this advice to be covered by the Rheem
warranty.
This water heater is manufactured to suit the water conditions of most public reticulated water supplies.
However, there are some known water chemistries which can have detrimental effects on the water heater
and its operation and / or life expectancy. If you are unsure of your water chemistry, you may be able to
obtain information from your local water supply authority. This water heater should only be connected to a
water supply which complies with these guidelines for the Rheem warranty to apply.
CHANGE OF WATER SUPPLY
The changing or alternating from one water supply to another can have a detrimental effect on the operation
and / or life expectation of a water heater cylinder and a temperature pressure relief valve.
Where there is a changeover from one water supply to another, e.g. a rainwater tank supply, bore water
supply, desalinated water supply, public reticulated water supply or water brought in from another supply,
then water chemistry information should be sought from the supplier or it should be tested to ensure the
water supply meets the requirements given in these guidelines for the Rheem warranty to apply.
ANODE
The vitreous enamel lined cylinder of the water heater is only covered by the Rheem 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 used. If an incorrect colour coded anode is used in the water heater, any resultant faults will not be
covered by the Rheem warranty. In addition, the use of an incorrect colour coded anode 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 11 for the Rheem warranty to apply to the water
heater cylinder.

The changing of an anode must be carried out by a qualified person.
Note: Some water analysis reports may state the conductivity of the water rather than the level of total
dissolved solids. Conductivity, measured in microsiemens per centimetre (µS / cm), is directly proportional to
the TDS content of the water. TDS, in mg / L, is approximately 70% of the conductivity in µS / cm.

ANODE INSPECTION AND REPLACEMENT
The anodes installed in a vitreous enamel lined steel water heater cylinder will slowly dissipate whilst
protecting the cylinder. The life of the cylinder may be extended by replacing the anodes.
If the anodes are not replaced during a five year service (refer to “Major Five Year Service” on page 9) then
the maximum time after installation when the anodes should be replaced for this water heater 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 anodes be replaced
within 5 years of installation.
CAUTION
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 an 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.
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.
In a scaling water supply calcium carbonate is deposited out of the water onto any hot metallic surface.
Where the saturation index exceeds +0.40, the water is very scaling. An expansion control valve must be
fitted on the cold water line after the non-return valve to protect and for the Rheem warranty to apply to the
temperature pressure relief valve and water heater cylinder.
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 13.
Refer to the cold water connection detail on page 30 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.
IN-SERIES BOOSTER OPERATING TOO FREQUENTLY
You may find that the in-series booster operates more frequently than expected. This will occur when the
solar heated water temperature is lower than the temperature setting of the in-series booster. This may be
experienced during periods of low solar energy gain or if there has been heavy hot water usage.
Hot tap not used recently
If a hot tap has not been used for a while, the water in the pipe work between the solar water heater and
the in-series booster may have cooled down. The in-series booster will sense the cooler water and this
will cause the in-series booster to operate and boost the water temperature when a hot tap is first turned
on. The in-series booster will de-energise when solar heated water from the solar storage tank of a
temperature higher than the booster‟s thermostat setting reaches the booster.
Solar Controller
Check the power supply cord to the solar water heater is plugged in and the power outlet switched on.
Is power available in the house? Try using another electrical appliance.
Insufficient sunlight
Insufficient sunlight due to cloudy weather during hotter months or low solar energy contribution in
colder months may mean the in-series booster operates more often.
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 10).
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.
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, basin and sink 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 15.
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
operating to provide all of the hot water required.
Switch off the electrical supply at the power outlet to the solar storage tank 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.
Water heater size
Do you have the correct size water heater for your requirements? The sizing guide in the sales literature
and on the Rheem website (www.rheem.com.au) suggests average sizes that may be needed.

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 10). 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 30) 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.
NO WATER FROM THE HOT TAP
No flow of water from the hot tap may indicate a restriction in or failure
of the cold water supply to the water heater. Check for water flow at
other taps and that the cold water isolation valve (refer to page 30) is
fully open.
COLLECTOR GLASS
The Rheem warranty DOES NOT cover breakage of solar collector glass. Check your household insurance
policy covers collector glass breakage.
Warning: No attempt should be made to remove or replace broken collector glass.
The collector glass is not offered as a replacement part. Should the solar collector require replacement,
contact Rheem Service or their nearest Accredited Service Agent.

HIGHER THAN EXPECTED ENERGY BILLS
With the installation of your new solar hot water system, maximum energy savings can be achieved with
careful planning of hot water usage. Should you at any time, feel your energy 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 15.
Is one outlet (especially the shower) using more hot water than
you think?
Refer to “In-Series Booster Operating Too Frequently” on page 14.
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.
Is the in-series booster operating too frequently?
Refer to “In-Series Booster Operating Too Frequently” on page 14.
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 energy
retailer since your previous account?
IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU NEED ASSISTANCE,
PHONE RHEEM SERVICE OR THEIR NEAREST ACCREDITED SERVICE AGENT.

INSTALLATION – SOLAR STORAGE TANK
Victorian Installers
Notice to Victorian Installers from the Victorian Plumbing Industry Commission if this solar water heater is
installed in a new Class 1 dwelling in the State of Victoria. The system model number is to be recorded on
the Certificate of Compliance. It is also a requirement to provide the householder with permanent
documentation recording the system model number exactly as it is shown in the „List of systems capable of
complying with the regulations‟ published by Sustainability Victoria (see www.sustainability.vic.gov.au). This
documentation may be in the form of an indelible label adhered to the solar storage tank, or other suitable
form placed in an accessible location, such as the meter box, for later inspection.
WATER HEATER APPLICATION
This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable
water. Its use in an application other than this may shorten its life.
If this water heater is to be used where an uninterrupted hot water supply is necessary for the application or
business, then there should be redundancy within the hot water system design. This should ensure the
continuity of hot water supply in the event that this water heater was to become inoperable for any reason.
We recommend you provide advice to the system owner about their needs and building backup redundancy
into the hot water supply system.
Note: AS 3498 requires that a water heater provides the means to inhibit the growth of Legionella bacteria in
potable water. If this water heater is installed with an continuous flow in-series 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.
SOLAR WATER HEATER STORAGE TANK LOCATION
The solar storage tank is suitable for either outdoor or indoor installation. 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 both the maximum length of the solar hot and solar cold pipes and the maximum
height between the solar storage tank and the solar collectors. Refer to “Solar Collector Location” on page 25
and to “Pipe Lengths” on page 26.
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 covers 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.
The water heater must not be installed in an area with a
corrosive atmosphere where chemicals are stored or
where aerosol propellants are released. Remember the air
may be safe to breathe, but when it goes through a flame,
chemical changes take place which may attack the water
heater.
It is recommended the solar storage tank be installed at ground or floor level and must stand vertically
upright. Remember all local authorities have regulations about putting water heaters into roof spaces.
Note: It is important for the solar storage tank to be orientated vertically upright in order for the falling film of
closed circuit fluid to operate efficiently.
The top of the solar storage tank must be a minimum of 500 mm below the bottom of the solar collectors for
the system to operate correctly.
18
INSTALLATION – SOLAR STORAGE TANK
SAFE TRAY
Where damage to property can occur in the event of the water heater
leaking, the water heater must be installed in a safe tray. Construction,
installation and draining of a safe tray must comply with AS/NZS 3500.4
and all local codes and regulatory authority requirements. AS/NZS 3500.4
also has particular requirements when a safe tray must be installed.
MAINS WATER SUPPLY
Where the mains water supply pressure exceeds that shown in the table below, an approved pressure
limiting valve is required and should be fitted as shown in the installation diagram on page 30.

TANK WATER SUPPLY
If the water heater is supplied with water from a tank supply and a pressure pump system is not installed,
then the bottom of the supply tank must be at least 1 m above the highest point of the hot water plumbing
system, including the solar storage tank. Care must be taken to avoid air locks. The cold water line to the
water heater should be adequately sized and fitted with a full flow gate valve or ball valve. Consideration
must be given to any minimum water supply pressure requirements of an in-series booster.
RAIN WATER TANK
If the solar collectors and solar pipe work are to be installed on a section of roof which is part of a rain water
runoff collection system, then it is recommended this section of roof and its gutter be isolated from the rain
water collection system. The gutter should be isolated to a width greater than the solar collectors and pipe
work and must have suitable drainage. The installer should ensure in the event of a leak from the solar
collectors or pipe work, a rainwater tank cannot be contaminated with closed circuit fluid.
While the closed circuit fluid is non toxic to humans, it does have an adverse effect on water stored in
rainwater tanks. It can cause an unpleasant odour to develop, render the rainwater foul and unfit for human
consumption and result in the rain water tank having to be drained and cleaned.
The section of roof and gutter should be isolated from the rainwater collection system before the
commissioning of the solar water heater, so that any leak or spillage during commissioning does not make its
way into the rainwater tank.
This section of roof and guttering can be isolated by either:
blocking this section of gutter from the remaining gutter and fitting two separate down pipes, one to take
any run-off water from that section of roof away to drain and the other to the rainwater collection side of
the gutter to take the rain water runoff to the rain water tank.
blocking this section of gutter from the remaining gutter and fitting a tube or pipe of a material
compatible with the gutter material in this section of the gutter and penetrating the separation pieces at
either end to allow rainwater runoff to pass from one part of the rainwater collection system to the other.
It may be necessary to fit a down pipe to the section of blocked gutter to take any run-off water from that
section of roof away to drain.
installing a false gutter inside of the existing gutter, with a down pipe penetrating the existing gutter to
take any run-off water from that section of roof away to drain. The false gutter should be no deeper than
half of the depth of the existing gutter, so as to enable rain water runoff to flow under the false gutter.
installing a flashing from the underside of the roofing material, with a continuous fall, to over the outside
lip of the gutter. The flashing should extend wider than the collectors and pipe work and turned up at the
ends so if there is leakage of closed circuit fluid, it cannot enter the gutter.
If any of these solutions are not practical, then the installer should discuss alternative options to suit the
installation with the house holder. Any alterations to the roof drainage system must comply with the relevant
building regulations, codes and Standards.
19
INSTALLATION – SOLAR STORAGE TANK
FREEZE PROTECTION
The water heater has a freeze protection system. The water heater is not suitable for installation in areas
where the ambient temperature falls below -20ºC.
The solar circuit must be installed with a continuous fall of a minimum 5° (1 in 10 grade) in the pipe work
from the solar collector to the solar storage tank, with the full length of the solar hot and solar cold pipes
insulated and the system charged with correctly mixed closed circuit fluid to offer protection against freeze
damage. The system has NO WARRANTY for freeze damage if there is not a continuous fall in the solar hot
and solar cold pipes, or they are not insulated in accordance with the installation instructions, or the closed
circuit fluid has been incorrectly mixed (refer to “Terms of the Rheem Warranty” on page 55 and to “Warning:
Plumber Be Aware” on page 27).
The solar collectors and solar cold and solar hot pipes only contain closed circuit fluid when the pump is
operating during periods of solar gain when heating is required. When the solar pump stops operating, the
closed circuit fluid drains back into the storage tank heat exchanger. The closed circuit fluid is an anti-freeze
agent which, when mixed to the correct specification, can withstand temperatures of -20°C before it may
freeze.
Damage to the water heater caused by freezing of the pipe work to or from the water heater is not covered
under the Rheem warranty. Refer to AS/NZS 3500.4 for precautions to be taken for installations in frost
prone areas.
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 in-series booster
and the hot water outlets in any ablution area such as a bathroom or ensuite, to reduce the risk of scalding.
The installing plumber may have a legal obligation to ensure the installation of this water heater meets the
delivery water temperature requirements of AS/NZS 3500.4 so that scalding water temperatures are not
delivered to a bathroom, ensuite or other ablution area.
The temperature limiting device used with a solar water heater should have a specified „minimum
temperature differential‟ between the hot water inlet and the tempered water outlet of no greater than 10°C.
Refer to the specifications of the temperature limiting device.
Where a temperature limiting device is installed adjacent to the in-series booster after an indirect solar water
heater, the cold water line to the temperature limiting device can be branched off the cold water line either
before or after the isolation valve, pressure limiting valve and non return valve to the solar storage tank. If an
expansion control valve is required, it must always be installed after the non return valve and be the last
valve prior to the solar storage tank.
If a pressure limiting valve is installed on the cold water line to the solar storage tank 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.

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 connect the return line after the solar
storage tank and prior to the in-series booster supplied from the solar water heater. Refer to the diagram on
page 21.
If the in-series water heater is a continuous flow water heater, its preset outlet temperature setting must be
set to at least 60°C or to meet the requirement of AS 3498, its setting must be set to at least 70°C.
If the in-series water heater is a storage water heater, its thermostat must always be set to at least 60°C.
Temperature Limiting Device
A temperature limiting device cannot be installed in circulated hot water flow and return pipe work. The
tempered water from a temperature limiting device cannot be circulated.
Where a circulated hot water flow and return system is required in a building, a temperature limiting device
can only be installed on a dead leg, branching off the circulated hot water flow and return pipe.
If circulated tempered water were to be returned back to the water heater, depending on the location of the
return line connection on the water supply line to the water heater, then either:
water will be supplied to the cold water inlet of the temperature limiting device at a temperature
exceeding the maximum recommended water supply temperature, or
when the hot taps are closed no water will be supplied to the cold water inlet of the temperature limiting
device whilst hot water will continue to be supplied to the hot water inlet of the temperature limiting
device.
These conditions may result in either water at a temperature exceeding the requirements of AS/NZS 3500.4
being delivered to the hot water outlets in the ablution areas, or the device closing completely and not
delivering water at all, or the device failing. Under either condition, the operation and performance of the
device cannot be guaranteed.

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 collector(s)
MUST BE insulated. Refer to “Warning: Plumber Be Aware” on page 27.
ANODE
The vitreous enamel lined cylinder of the water heater is only covered by the Rheem 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 used. If an incorrect colour coded anode is used in the water heater, any resultant faults will not be
covered by the Rheem warranty. In addition, the use of an incorrect colour coded anode may shorten the life
of the water heater cylinder.
The correct colour coded anode for the water supply being used must be selected and fitted to the water
heater for the Rheem warranty to apply to the water heater cylinder (refer to “Water Supplies” on page 11
and the Anode Selection chart on page 11). 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 an 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 12).
SADDLING - PIPE WORK
To prevent damage to the cylinder when attaching pipe clips or saddles to the water heater jacket, we
recommend the use of self-drilling screws with a maximum length of 13 mm. Should pre drilling be required,
extreme caution must be observed when penetrating the jacket of the water heater.
Note: If the cylinder is damaged as a result of attaching pipe clips or saddles to the jacket, any
resultant faults will not be covered by the Rheem warranty.

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 both the maximum length of the solar hot and solar cold pipes and the maximum height
between the solar storage tank and the solar collectors. Refer to “Solar Storage Tank Location” on page 18
and to “Pipe Lengths” on page 26.
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 26. Solar collectors may be installed
at the roof angle for simplicity of installation and
appearance, but must never be less than 10° from the
horizontal. If the roof angle varies by 15° from the
optimum angle, the solar collectors will receive about
10% less total solar radiation.
The collector kit is suitable for installations with an inclination of up to 45°. Where the solar collectors are
installed at inclinations greater than 45°, 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 is required. 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

also provides an acceptable method of installation where it is necessary to satisfy the requirements
of the Building Code of Australia and AS/NZS 3500.4 Clause 6.5.3.4 for high wind areas.
The installer must ensure the structural integrity of the building is not compromised by the 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 46 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.

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.
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 collectors and the solar hot pipe connects to the
top of the solar collectors diagonally opposite to the solar cold pipe connection.
The lowest corner of the solar collector installation, which is where the solar cold pipe connects to the
collector array, should be the corner closest to the solar storage tank. This will maximise the gradient for
the continuous fall of the solar cold pipe, by providing a shorter horizontal run of pipe work for the
vertical fall.
The hot sensor connection is at the top of the solar collector, directly above the solar cold inlet
connection.
Refer to “Warning: Plumber – Be Aware” on page 27.
It is essential for these requirements to be followed for the system to operate correctly and efficiently. Solar
pipe work which is oversized, or does not have the correct fall, or is too long can result in the drain back
system not operating effectively.
26
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 closed circuit fluid generated by the solar collectors under
stagnation conditions
The specification of the chosen insulation material should be checked with the insulation
manufacturer prior to installation as different materials may vary in temperature tolerance.

be at least 13 mm thick, however thicker insulation may be required to comply with the
requirements of AS/NZS 3500.4

be weatherproof and UV resistant 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.
The insulation will offer corrosion protection to a metal roof against water runoff over the copper pipe,
assist in avoiding accidental contact with the solar pipe work as high temperature closed circuit fluid
can flow from the solar collectors to the solar storage tank and also reduce pipe heat losses.
There MUST BE a continuous fall of a minimum 5° (1 in 10 grade) in the pipe work between the
solar collector and solar storage tank for efficient and effective drain back to occur. The highest point
of the solar cold pipe and solar hot pipe must be where they connect to the solar collector.
The system has NO WARRANTY for freeze damage if there is not a continuous fall in the solar hot
and solar cold pipes, or they are not insulated in accordance with the installation instructions, or the
closed circuit fluid has been incorrectly mixed.
The insulated copper pipe work:

should be fixed at suitable locations to prevent or reduce the possibility of noise from water
hammer and vibration from occurring

is not to be placed or installed in contact with plastic pipe work.
Likewise, plastic pipe work is not to be placed or installed in contact with the insulated copper
pipe work after the solar circuit is installed.
Plastic pipe MUST NOT be used, as it will not withstand the temperature of the closed circuit fluid
generated by the solar collectors under stagnation conditions. The solar collectors can generate
extremely high closed circuit fluid temperatures of up to 150°C. Plastic pipe cannot withstand these
temperatures and MUST NOT be used. Failure of plastic pipe can lead to the release of high
temperature closed circuit fluid and cause severe water damage and flooding.
The pressure applied to the solar circuit and solar collectors during a pressure test of an indirect
closed circuit system MUST NOT exceed 200 kPa, otherwise damage may result to the solar
collectors. Refer to “Pressure Testing” on page 29.
27
INSTALLATION – SOLAR COLLECTORS
Maximum Height To Collectors
The solar collectors must be the highest point of the system. The maximum height of the solar installation,
from the base of the solar storage tank to the top of the solar collectors, is 9 m. The pump supplied with the
solar storage tank will not circulate closed circuit fluid through heights greater than 9 m and solar gain will not
be achieved.
For heights greater than 9 m, an auxiliary pump (kit PN 299914) must be installed above and within 1 m of
the solar storage tank. The installation of an auxiliary pump will enable a maximum height of 18 m to be
achieved. Refer to “Auxiliary Pump” on page 35.
Note: The top of the solar storage tank must be a minimum of 500 mm below the bottom of the solar
collectors for the system to operate correctly.

INSTALLATION – SOLAR COLLECTORS
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.
Indirect Closed Collector Circuit
Warning: The pressure applied to the solar circuit and solar collectors during a pressure test of an
indirect closed circuit system MUST NOT exceed 200 kPa, otherwise damage may result to the solar
collectors. The solar circuit and solar collectors are to be isolated from the solar storage tank for the duration
of the pressure test.
S200 and T200 Solar Collector Installations
If water is used as the pressure testing medium and if the collector circuit is not to be connected to the solar
storage tank and the system commissioned on the same day, then any excess moisture needs to be blown
out and the collector circuit and solar collectors dried using dry compressed air.
It is necessary to cap off the ends of the solar cold and solar hot pipes if they are not connected to the solar
storage tank at the time of installation and at the time of testing the solar circuit.
Indirect Closed 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 closed circuit fluid for an indirect closed circuit system or water under
mains pressure for a direct open circuit system and checking for the pipe work for leaks during the
commissioning procedure can be substituted for the pressure testing of the collector circuit.

CONNECTIONS – PLUMBING
All plumbing work must be carried out by a qualified person and in accordance with the requirements of the
Standard AS/NZS 3500.4, and all local codes and regulatory authority requirements. In New Zealand, the
installation must conform with Clause G12 of the New Zealand Building Code.
Note: The solar storage tank of a solar water heater should not be installed as part of a circulated hot water
flow and return system in a building. The benefits of solar gain will be significantly reduced and energy
gained from the sun lost through the pipe work. If a circulated flow and return system is required, it is
necessary to connect the return line after the solar storage tank and prior to the in-series water heater
supplied from the solar water heater. Refer to “Circulated Hot Water Flow and Return System” on page 21.
CONNECTION SIZES
Hot water connection: RP¾/20.
Cold water connection: RP¾/20.
Solar hot (from collector) connection: DN15 compression fitting.
Solar cold (to collector) connection: DN15 compression fitting.
Temperature Pressure Relief valve connection: RP½/15.
Solar circuit pressure relief valve connection: R½/15.

WATER INLET AND OUTLET
All pipe work must be cleared of foreign matter before
connection and purged before attempting to operate the
water heater. All olive compression fittings must use brass
or copper olives. Use thread sealing tape or approved
thread sealant on all fittings.
An isolation valve and non return valve must be installed
on the cold water line to the water heater. An acceptable
arrangement is shown in the diagram. Refer also to “Hot
Water Delivery” on page 20 and to “Mains Water Supply”
on page 19. The solar hot and solar cold pipe connections
are shown on page 32.
A disconnection union must always be provided at the cold water inlet and hot
water outlet on the water heater to allow for disconnection of the water heater.
This solar storage tank 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 tempered water and hot water lines 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 WATER HEATER
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 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.
30
CONNECTIONS – PLUMBING
TEMPERATURE PRESSURE RELIEF VALVE
The temperature pressure relief valve is shipped behind the lower front cover of the water heater. 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 24) 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 31).
The valve must be insulated with a closed cell type insulation or equivalent (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 11).
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 30). A copper drain line must be fitted to the
expansion control valve (refer to "Relief Valve Drain" on page 31).
The valve must be insulated with a closed cell type insulation or equivalent (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.
RELIEF VALVE DRAIN
DN15 copper drain lines must be fitted to the temperature pressure relief valve, expansion control valve (if
one is installed) and solar circuit relief valve to carry the discharge clear of the water heater. Ensure the
outlet of the solar circuit relief valve is facing toward the rear of the water heater installation. 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 easily seen, but arranged
so discharge will not cause injury, damage or nuisance. The termination point of a drain line must comply
with the requirements of AS/NZS 3500.4. Drain lines must not discharge into a safe tray.
In locations where water pipes are prone to freezing, drain lines must be insulated, must not exceed 300 mm
in length and are to discharge into a tundish through an air gap of between 75 mm and 150 mm.
If a drain line discharges into a tundish, the drain line from the tundish must be not less than DN20. The drain
line from a tundish must meet the same requirements as for a drain line from a relief valve.
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.

MEGGER READING
It is not mandatory to conduct a megger test on a plug in appliance, however if a megger test is conducted
on this water heater, then the following should be noted.
Warning: This water heater contains electronic equipment and 500 V insulation tests must only be
conducted between either active and earth or neutral and earth. An active to neutral test WILL damage the
electronics.
An insulation test result of approximately 660 KΩ for this water heater is normal.
Typically the insulation resistance between live and earthed parts of an electrical installation should not be
less than 1 MΩ. However AS/NZS 3000:2000 clause 6.3.3.3.2 „Results‟ states:
“The value of 1 MΩ may be reduced to:
0.01 MΩ for sheathed heating elements or appliances; or
a value permitted in the Standard applicable to electrical equipment.”
This model water heater is categorised as a „stationary class 1 motor operated appliance‟ and has been
tested to AS/NZS 3350.1:2002 clause 16 „Leakage current and electric strength‟ and has passed the
requirements of this Standard. Therefore, this model water heater complies with the condition stated in
AS/NZS 3000:2000 clause 6.3.3.3.2 (b).
ELECTRICAL CONNECTION
All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the
Wiring Rules AS/NZS 3000 and all local codes and regulatory authority requirements.
Warning: Temperature controllers must not be fitted to the in-series booster as part of a solar water
heater system because water at a temperature much higher than the controller setting can be delivered.
The water heater requires a 240 V AC, 50 Hz mains power supply for operation. The solar storage tank,
supplied with a 1.8 metre power cord to operate the solar controls requires a switched general purpose outlet
(GPO) to be located within 1.2 metres of the installation. The GPO must have a continuous power supply.
The GPO is required to be weatherproof if installed outdoors.

COMMISSIONING
TO FILL AND TURN ON THE WATER HEATER
The power supply to the water heater must not be switched on until the solar storage tank is filled
with water.
To fill the solar storage tank with water and turn on the water heater:
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.
Open the isolation valve in the pipe work between the outlet of the heat exchanger and the solar pump,
located behind the lower front cover of the solar storage tank (refer to step 4 of “Commissioning the
Solar Circuit” on page 41).
Plug in the water heater at the power outlet.
Commission the solar circuit (refer to “Solar Circuit” on page 39).
Switch on the electrical supply at the power outlet to the water heater.
The power outlet must be switched on for the solar controls to operate and solar gain to be achieved.
Refer to the Owner‟s Guide and Installation Instructions supplied with the in-series booster for the
commissioning procedure of the water heater.
Check and if required adjust the preset outlet temperature or thermostat setting of the in-series booster.
Explain to the householder or a responsible officer the functions and operation of the solar water heater.
Upon completion of the installation and commissioning of the water heater, leave this guide with the
householder or a responsible officer.
PRESET OUTLET TEMPERATURE SETTING
Note: AS 3498 requires that a water heater provides the means to inhibit the growth of Legionella bacteria in
potable water. If this water heater is installed with an continuous flow in-series 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.
It will be necessary to check and if required to adjust the preset outlet temperature setting of the continuous
flow water heater or the thermostat setting of a storage water heater when it is installed as an in-series
booster to a solar water heater or if it is an existing water heater and a solar water heater is then installed.
Refer to the Owner‟s Guide and Installation Instructions supplied with the continuous flow in-series gas
booster for the procedure to check and adjust the preset outlet temperature if required.
Refer to the Owner‟s Guide and Installation Instructions supplied with the in-series storage booster for the
procedure to check and adjust the thermostat setting if required.
Note: Consideration must be given to the delivery temperature to any ablution and public areas such as a
bathroom, ensuite or public amenities. Refer to “Hot Water Delivery” on page 20 and to the schematics of
“Two Temperature Zones Using A Temperature Limiting Device” on page 20.
38
COMMISSIONING
SOLAR CIRCUIT
It is necessary to commission and check the operation of the solar circuit as part of the installation. The
water heater is supplied charged with closed circuit fluid.
The commissioning procedure includes checking the:
circulation of closed circuit fluid through the solar circuit.
drain back function of the solar circuit.
solar circuit under circulation to ensure there are no leaks.
level of the closed circuit fluid.
The level of the closed circuit fluid should not have to be adjusted, but may need to be if:

there is a significant leak in the solar pipe work and closed circuit fluid has been discharged.

a third solar collector is installed.

the maximum recommended solar pipe length is exceeded.
Additional Equipment
Additional equipment will be required for the commissioning and checking of the solar circuit. This includes
checking the closed circuit fluid level and conducting a drain back test. The following equipment is required:
a 1500 mm long x 12 mm (½”) diameter clear hose (closed circuit fluid level hose).
one (1) ½” hose clamp.
a suitable plug for one end of the hose.
suitable tape to affix the hose to the side of the solar storage tank.
a torch to illuminate the working area under the heat exchanger and storage tank cylinder.
a non-permanent marker.
Closed Circuit Fluid
The water heater is supplied charged with closed circuit fluid and it is not necessary to add further closed
circuit fluid to the system. If the closed circuit fluid has been completely drained or discharged from the solar
circuit and needs to be replaced, then the amount to be added is:
4.5 litres of concentrate, mixed with
11.5 litres of water.
It is necessary to undertake the solar circuit commissioning procedure if the closed circuit fluid has been
replaced.
The closed circuit fluid contains food grade additives (rust inhibitor, anti-freeze agent, colour) and is harmless
to the environment. However, it is good practice to recover any excess closed circuit fluid and remove from
site for appropriate disposal.
39
COMMISSIONING
Warning: Although non-toxic, the following first aid advice and procedures should be followed if the
closed circuit fluid concentrate comes into human contact or is spilt:
Swallowed - give milk or water and seek medical attention.
Eyes - wash with running water.
Skin - remove contaminated clothing and wash skin with water and soap.
Inhaled - seek fresh air, rest and keep warm.
Spilt - immediately remove contaminated clothing, stop leak source, absorb with a dry agent and
eliminate any ignition sources nearby.
PRE-COMMISSIONING WARNINGS
It is recommended to conduct the solar circuit commissioning procedure with the solar collectors
covered, otherwise during the commissioning and checking procedure of the solar circuit, the closed
circuit fluid may experience solar gain as it passes through the solar collectors. This will increase both
the temperature and pressure of the closed circuit fluid and vapour inside of the solar circuit.
The electrical supply must be switched off before the solar circuit is opened either at the solar circuit
relief valve or at the compression nut on either of the solar hot or solar cold pipes at the top of the solar
storage tank.
If it is necessary to open the solar circuit at the solar circuit relief valve or at the compression nut on
either of the solar hot or solar cold pipes at the top of the solar storage tank, then care must be taken so
as not to be scalded by either the closed circuit fluid or the vapour escaping from the solar circuit.
Pre-Commissioning Notes
Before commencing the solar circuit commissioning procedure, check the solar cold and solar hot pipe
work to ensure:

there is a continuous fall from the solar collectors to the solar storage tank of a minimum 5° (1 in
10 grade).

the maximum recommended pipe length is not exceeded.

the maximum height from the base of the solar storage tank to the solar collector is not exceeded.
Rectify the solar pipe work if there is either insufficient fall or not a continuous fall of at least 5° from
the solar collectors to the solar storage tank or if either of the maximum pipe length or maximum
height of the system has been exceeded, before commencing the solar circuit commissioning
procedure. Refer to “Pipe Lengths” on page 26.
The solar collectors will gain a high level of heat during periods of solar radiation. If the solar pump is
activated during a period of high solar radiation and the solar collectors have not been covered, the
initial flow of closed circuit fluid will absorb this heat and a rumbling sound may be heard. This is normal
and the solar circuit will achieve a stable operating condition once full flow through the solar circuit is
established.
The solar pump is set on the speed setting 3. This speed setting must not be adjusted. The solar control
unit automatically controls and adjusts the speed of the pump to maximise solar contribution. Manual
adjustment of the speed dial setting may result in the system not operating correctly or efficiently.

COMMISSIONING
Commissioning the Solar Circuit
To commission and check the solar circuit:
1.
Switch off the electrical supply at the power outlet to the solar storage tank.
If the pump has been operating, wait five minutes to allow the drain back of the closed circuit fluid in the
solar circuit.
2.
Cover the solar collectors with an opaque material to prevent solar gain during the commissioning
process.
3.
Remove the lower and upper front covers from the solar storage tank.

COMMISSIONING
Drain Back Function
14. Switch off the electrical supply at the power outlet to the solar storage tank.
The red LED on the solar monitor label will stop flashing.
The pump will deactivate.
The closed circuit fluid will drain back down to the heat exchanger and the level of the closed circuit fluid
in the clear hose will rise.
Wait five (5) minutes to allow the drain back of the closed circuit fluid in the solar circuit.
15. Note the level of the closed circuit fluid in the fluid level hose.
The closed circuit fluid should drain back to the original static level.
If the closed circuit fluid does not drain back completely to this level, then check:

there is a continuous fall of at least 5° (1 in 10 grade) in the solar pipe work from the solar collectors
to the solar storage tank.

the solar collectors have an inclination of not less than 10°.
(refer to “Solar Collector Location” on page 25)

the connectors on the inlet and outlet of the collectors are orientated downwards to ensure
complete drain back of the closed circuit fluid from the solar collectors.
If necessary, rectify the:

solar pipe work if there is either insufficient fall or not a continuous fall in the pipe work.

solar collector inclination if it is less than 10°.

orientation of the connectors downwards if they are not orientated correctly.
Recheck the drain back function of the solar circuit by repeating step 8 and recommencing this
procedure from step 10.

COMMISSIONING
Closed Circuit Fluid Level
16. Measure the distance from the text marking “MINIMUM FLUID LEVEL WITH PUMP OPERATING” to the
closed circuit fluid dynamic level marked on the side of the solar storage tank during step 12.
The correct closed circuit fluid dynamic level for efficient operation of the system when the pump is
operating is between the “MINIMUM FLUID LEVEL WITH PUMP OPERATING” text marking on the side
of the solar storage tank and 150 mm above this mark.

If the closed circuit fluid dynamic level marked on the side of the solar storage tank during step 12 is
greater than 150 mm above the text marking, it will be necessary to drain closed circuit fluid from
the heat exchanger.

If the closed circuit fluid dynamic level is below the text marking, it will be necessary to add water to
the heat exchanger to top up the level of closed circuit fluid.
There is sufficient closed circuit concentrate in the solar circuit heat exchanger such that only water
needs to be added to the system if it is required to top up the level of closed circuit fluid.
Note: The dynamic level of the closed circuit fluid, upon the completion of commissioning, must not be
less than the “MINIMUM FLUID LEVEL WITH PUMP OPERATING” text marking on the side of the solar
storage tank or greater than 150 mm above this mark.

solar storage tank during step 8.
E.g.: If the dynamic level is 30 mm below the text marking, then place a mark 30 mm above the
static level marked on the side of the solar storage tank in step 8. It would be necessary to add one
litre of water to the heat exchanger.
E.g.: If the dynamic level is 180 mm above the text marking, then place a mark at least 30 mm, but
no more than 180 mm, below the static level marked on the side of the solar storage tank. It would
be necessary to drain between one litre and five litres of closed circuit fluid from the heat
exchanger.

18. Add water to top up the level of the closed circuit fluid in the heat exchanger if required.
To add water to the closed circuit fluid:

If not already removed, disconnect the drain line and remove the spring clip from the solar circuit
relief valve at the top of the solar storage tank and remove the valve (refer to step 6).
Warning: The solar circuit may be under pressure. Take care when removing the solar circuit
relief valve, as a sudden discharge of pressurised hot vapour may be experienced. This discharge
will create a sharp sound of vapour being released.

Undo the compression nut on the solar cold pipe at the top of the solar storage tank and remove the
pipe work from the fitting.

Place a funnel in the solar cold connection fitting at the top of the solar storage tank.

Add water slowly through the funnel until the level of fluid in the hose is at the desired level as
marked on the solar storage tank.
Note: It may be necessary to either lift the funnel slightly to allow air to escape around the funnel
whilst filling.

Remove the funnel from the solar cold connection fitting.

Position the solar cold pipe correctly in its fitting and tighten the compression nut.
19. Drain closed circuit fluid from the heat exchanger if required.
To drain closed circuit fluid:

If not already removed, disconnect the drain line and remove the spring clip from the solar circuit
relief valve at the top of the solar storage tank and remove the valve (refer to step 6).
Warning: The solar circuit may be under pressure. Take care when removing the solar circuit
relief valve, as a sudden discharge of pressurised hot vapour may be experienced. This discharge
will create a sharp sound of vapour being released.

Place the end of the solar fluid hose into a graduated volumetric container and drain closed circuit
fluid until the level of fluid in the hose is at the desired level as marked on the solar storage tank.
It may be necessary to drain off the closed circuit fluid in small amounts, raising the hose back to
the top of the solar storage tank and noting the level of the closed circuit fluid in the clear hose each
time, so as not to drain below the desired level.
Note: The closed circuit fluid contains food grade additives (rust inhibitor, anti-freeze agent, colour)
and is harmless to the environment. However, it is good practice to recover any excess fluid and
remove from site for appropriate disposal.

Re-affix the hose to the same location on the side of the solar storage tank.
20. If water has been added to or closed circuit fluid has been drained from the heat exchanger,
recommence this procedure from step 10.

the power is on as the electrical circuit will be live.
The red LED on the solar monitor label will start flashing and the pump will activate and commence
pumping fluid around the solar circuit.
Note: The level of the closed circuit fluid in the clear hose will not change, as the heat exchanger drain
valve has been closed.
Allow the pump to operate for three (3) minutes (one and two collector systems) or for five (5) minutes
(three collector system) to allow the solar circuit to stabilise and fill with closed circuit fluid.
Note: The solar pump will operate for one hour with the hot sensor lead disconnected, before
automatically turning itself off. Refer to step 25.
24. Check the solar pipe work and collector unions for leaks whilst the pump is operating and the solar
circuit is at its working pressure. It is important to check all of the solar circuit pipe work, including in the
roof space and on the roof.
25. If the procedure to check the solar pipe work for leaks is not complete before the pump has
automatically turned off, then:

switch off the electrical supply at the power outlet to the solar storage tank.

recommence this procedure from step 23.
26. Switch off the electrical supply at the power outlet to the solar storage tank.
The red LED on the solar monitor label will stop flashing and the pump will deactivate.
The closed circuit fluid will drain back down to the heat exchanger.
27. Rectify any leaks in the solar pipe work and collector unions.
If brazing is required to fix any leaks, then it is necessary to remove the solar circuit relief valve (refer to
step 6).
Warning: The solar circuit may be under pressure. Take care when removing the solar circuit relief
valve, as a sudden discharge of pressurised hot vapour may be experienced. This discharge will create
a sharp sound of vapour being released.

DIAGNOSTIC FEATURES OF THE SOLAR CONTROLLER
The solar storage tank incorporates a solar monitor which is connected to the solar control module by a
ribbon cable. The solar monitor is located on the lower front cover and houses both 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.

Notes:
Warning: The removal of the lower front cover will expose 240 V wiring. Switch off the electrical
supply at the power outlet to the water heater before removing the lower front cover and if necessary
disconnecting the ribbon cable from the solar control module. The lower front cover and the ribbon cable
must only be removed by a qualified person.
The ribbon cable connecting the solar monitor to the solar control module has sufficient length to enable
the removal of the lower front cover and for it to be set to one side of the opening, without disconnecting
the ribbon cable from the solar control module.
The ribbon cable can be disconnected from the solar control module if it is necessary to remove the
lower front cover completely from the work area in front of the solar storage tank.
If the ribbon cable from the solar monitor has been disconnected, reconnect it to the solar control
module prior to replacing the lower front cover.
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 power outlet to the water heater.
Close the cold water isolation valve at the inlet to the water heater.
50
DRAINING THE WATER HEATER
Solar Storage Tank
Warning: Exercise care, as water discharged from the solar storage tank may be of a very high
temperature.
To drain the solar storage tank:
Turn off the water heater (refer to “To Turn Off The Water Heater” on page 50).
Close all hot water taps.
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 solar storage tank and attach a hose to the water heater
side of the union.
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.
Heat Exchanger
Warning: Exercise care, as fluid discharged from the heat exchanger may be of a very high temperature.
To drain the heat exchanger:
Switch off the electrical supply at the power outlet to the water heater.
Remove the lower front cover from the solar storage tank.
The solar monitor located on the lower front cover is connected to the solar control module by a ribbon
cable. The ribbon cable has sufficient length to enable the removal of the lower front cover and for it to
be set to one side of the opening without disconnecting the ribbon cable from the solar control module.
The ribbon cable can be disconnected from the solar control module if it is necessary to remove the
lower front cover completely from the work area in front of the solar storage tank.
At the completion of this procedure, if the ribbon cable from the solar monitor has been disconnected,
reconnect it to the solar control module prior to replacing the lower front cover.
Attach a 12 mm (½”) diameter clear hose to the heat exchanger drain valve hose tail connection (refer to
step 5 of “Attach Closed Circuit Fluid Level Hose” on page 41).
Disconnect the drain line from the solar circuit relief valve at the top of the solar storage tank. Remove
the spring clip from the solar circuit relief valve and remove the valve.
Warning: The solar circuit may be under pressure. Take care when removing the solar circuit relief
valve, as a sudden discharge of pressurised hot vapour may be experienced. This discharge will create
a sharp sound of vapour being released.
Open the heat exchanger drain valve and remove the plug from the end of the hose.
The closed circuit fluid will flood the hose.
Place the end of the hose into a container and drain the closed circuit fluid from the heat exchanger.
Note: The heat exchanger can contain up to 16 litres of closed circuit fluid. A suitably sized container
should be used to accommodate this amount of fluid.
The closed circuit fluid contains food grade additives (rust inhibitor, anti-freeze agent, colour) and is
harmless to the environment. However, it is good practice to recover any excess closed circuit fluid and
remove from site for appropriate disposal.
