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 thermosiphon solar water heater is designed for both the solar collectors and the solar storage tank to be roof mounted. The solar storage tank has a Colorbond jacket.
ABOUT YOUR WATER HEATER ELECTRIC BOOSTING Water stored in the solar storage tank can be heated by an electric booster heating unit. The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy or rainy weather, or during the colder months. The amount of water heated by the raised booster heating unit of the thermosiphon solar storage tank is 90 litres (180 tank) or 150 litres (300 tank).
ABOUT YOUR WATER HEATER 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.
ABOUT YOUR WATER HEATER PRECAUTIONS Where damage to property can occur in the event of the water heater leaking, the water heater must be installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4 and all local codes and regulatory authority requirements. The water heater must be maintained in accordance with the Owner‟s Guide and Installation Instructions. Refer to “Regular Care” on page 11.
ABOUT YOUR WATER HEATER Programming the Timer Power must be available to the timer control switch before the booster heating unit can be activated.
ABOUT YOUR WATER HEATER FREEZE PROTECTION The 52H and RLX series solar water heaters are an indirect closed circuit solar hot water system with a heat exchanger in the solar storage tank. The heat exchanger and solar collectors form a closed circuit and are filled with closed circuit fluid. The closed circuit fluid is a solution of a blue, non-toxic food grade propylene glycol concentrate mixed with water.
ABOUT YOUR WATER HEATER TO TURN OFF THE WATER HEATER If you plan to be away from home for a few nights, we suggest you leave the water heater switched on. If it is necessary to turn off the water heater: Switch off the electrical supply at the isolating switch to the solar storage tank. Close the cold water isolation valve at the inlet to the water heater. TO TURN ON THE WATER HEATER Open the cold water isolation valve fully at the inlet to the water heater.
REGULAR CARE MINOR SIX MONTH MAINTENANCE It is recommended minor maintenance be performed every six months by the dwelling occupant. The minor maintenance includes: Operate the easing lever on the temperature pressure relief valve (if accessible). It is very important you raise and lower the lever gently. Refer to “Temperature Pressure Relief Valve” on page 12. If the relief valve lever is not readily and safely accessible, contact Rheem Service or their nearest Accredited Service Agent.
REGULAR CARE TEMPERATURE PRESSURE RELIEF VALVE This valve is near the top of the water heater and is essential for its safe operation. It is possible for the valve to release a little water through the drain line during each heating period. This occurs as the water is heated and expands by approximately 1/50 of its volume. Continuous leakage of water from the valve and its drain line may indicate a problem with the water heater (refer to “Temperature Pressure Relief Valve Running” on page 17).
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.
WATER SUPPLIES SATURATION INDEX The saturation index is used as a measure of the water‟s corrosive or scaling properties. In a corrosive water supply, the water can attack copper parts and cause them to fail. Where the saturation index is less than –1.0, the water is very corrosive and the Rheem warranty does not apply to a copper sheathed heating unit or a solar collector in a direct solar water heater system.
WATER SUPPLIES SUMMARY OF WATER CHEMISTRY ADVICE AFFECTING WARRANTY The water heater and its components are not suitable for certain water chemistries. Those chemistries are listed below. If the water heater is connected at any time to a water supply with the following water chemistry, the Rheem warranty will not cover any resultant faults on the components listed below: Water Chemistry Component Chloride > 250 mg/L water heater cylinder and heat exchanger pH < 6.
SAVE A SERVICE CALL Check the items below before making a service call. You will be charged for attending to any condition or fault that is not related to manufacture or failure of a part. NOT ENOUGH HOT WATER (OR NO HOT WATER) This can occur with new installations and is normally related to some misunderstandings as to the use of the booster heating unit.
SAVE A SERVICE CALL WATER NOT HOT ENOUGH You may find that due to heavy hot water usage or low solar energy gain the water temperature may be lower than normally expected. Ensure the booster is being used as advised. If a timer is installed, you will need to carefully plan your use of the booster heating unit to boost the water temperature on such occasions. Refer to “Booster Control” on page 7.
SAVE A SERVICE CALL 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.
INSTALLATION THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING. SOLAR COLLECTORS The 52L tank is suitable for installation with Rheem Australis or Titan solar collectors and the 52H tank is suitable for installation with Rheem S200, Australis or Titan solar collectors. In Australia, systems with Australis or S200 collectors are suitable for installation in all climate zones. In Australia for climate zones 1, 2, and 3 there is a risk that systems with Titan collectors may over perform.
INSTALLATION FREEZE PROTECTION The 52L and RL series systems do not have freeze protection. These systems are not suitable for installation in areas subject to frost or freeze conditions. Freeze conditions occur below 6°C. The system has NO WARRANTY for freeze damage (refer to “Terms of the Rheem Warranty” on page 62). The 52H and RLX series systems are suitable for installation in areas subject to frost or freeze conditions. Freeze conditions occur below 6°C.
INSTALLATION SOLAR WATER HEATER STORAGE TANK LOCATION The solar storage tank is designed to be installed on the roof directly coupled to the solar collectors. The solar water heater should be installed close to the most frequently used outlet and its position chosen with safety and service in mind. The solar water heater should be installed with a north facing aspect (refer to “Solar Collector Location” on page 34).
INSTALLATION RAIN WATER TANK If a 52H or RLX series system is 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.
INSTALLATION HOT WATER DELIVERY This water heater can deliver water at temperatures which can cause scalding. It is necessary and we recommend that a temperature limiting device be fitted between the water heater and the hot water outlets in any ablution area such as a bathroom or ensuite, to reduce the risk of scalding. The installing plumber may have a legal obligation to ensure the installation of this water heater meets the delivery water temperature requirements of AS/NZS 3500.
INSTALLATION If a pressure limiting valve is installed on the cold water line to the solar water heater and the cold water line to a temperature limiting device branches off before this valve or from another cold water line in the premises, then a pressure limiting valve of an equal pressure setting may be required prior to the temperature limiting device.
INSTALLATION 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.

If in doubt use a spirit level.
CONNECTIONS – PLUMBING All plumbing work must be carried out by a qualified person and in accordance with the requirements of the Standard AS/NZS 3500.4, and all local codes and regulatory authority requirements. In New Zealand, the installation must conform with Clause G12 of the New Zealand Building Code.
CONNECTIONS – PLUMBING Pipes must not be installed in direct contact with metal roofs. Where it is necessary to run piping across a metal roof, it must be fixed above the roof and surrounded with a weatherproof insulation of a minimum thickness in accordance with Clause 4.12.3 of AS/NZS 3500.4. The insulation must be UV resistant if exposed. The insulation is to assist in freeze protection and to protect the metal roof against corrosion by water runoff over the copper pipe.
CONNECTIONS – PLUMBING EXPANSION CONTROL VALVE An expansion control valve is supplied in the pipe kit and must be installed. Install the expansion control valve using a brass Tee, brass union and brass nipple on the cold water line to the water heater. Local regulations may make it mandatory to install an expansion control valve (ECV) in the cold water line to the water heater. In other areas, an ECV is required if the saturation index is greater than +0.4 (refer to “Water Supplies” on page 13).
CONNECTIONS – ELECTRICAL The power supply to the water heater must not be switched on until the water heater is filled with water and a satisfactory megger reading is obtained. All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the Wiring Rules AS/NZS 3000 and all local codes and regulatory authority requirements.
CONNECTIONS – ELECTRICAL BOOSTER CONTROL The isolating switch installed in the electrical meter box for the solar storage tank should be left switched on.

COMMISSIONING TO FILL AND TURN ON THE WATER HEATER The power supply to the solar storage tank must not be switched on until the water heater is filled with water and a satisfactory megger reading is obtained. Open all of the hot water taps in the house (don‟t forget the shower). Open the isolation valves fully on the cold and hot water branches to the water heater(s) in a bank. Open the cold water isolation valve fully on the cold water line to the water heater(s). Air will be forced out of the taps.
COMMISSIONING CLOSED CIRCUIT FLUID Important: It is recommended the solar storage tank be filled with water before charging the solar heat exchanger with the closed circuit fluid. The closed circuit concentrate is supplied in 1.5 litre bottles. Mix the required quantity of closed circuit concentrate with the correct quantity of water to achieve the correct closed circuit fluid for the system. Failure to mix the closed circuit fluid correctly may void the Rheem warranty.
COMMISSIONING Close the Service Valve or remove the hose and refit the screw into the Fill Plug Assembly. Insert the 200 kPa pressure relief valve into the vent socket and secure with the retaining clip. Pressurise the closed circuit system up to 170 kPa and leave for ten minutes. Check the system for leaks at all connections.
DRAINING THE SOLAR STORAGE TANK To drain the solar storage tank: Cover the solar collectors to prevent solar radiation gain and the transfer of heat to the solar storage tank. Failure to do so may cause a safety issue. Open a hot water tap and allow the water to run for five minutes immediately prior to draining the solar storage tank. This will assist in the transfer of any heat from high temperature closed circuit fluid in the solar collectors to the water in the solar storage tank.
DRAINING THE CLOSED CIRCUIT – 52H / RLX SERIES It is recommended to drain the solar collectors and heat exchanger every five years. The closed circuit fluid should be checked and if necessary replaced. Draining the solar collectors and closed circuit should be conducted within three hours of sunrise, when the closed circuit fluid temperature inside the solar collectors is lower. To drain the solar collectors and closed circuit: Cover the solar collectors to prevent solar radiation gain.
FLUSHING THE WATER HEATER It may be necessary to flush the storage tank (52H or 52L tank) and solar collectors (52L) if there is sediment in the water supply. This should be conducted in the morning, within three hours of sunrise, when the water or closed circuit fluid temperature inside the solar collectors is lower. Cover the solar collectors to prevent solar radiation gain and the transfer of heat to the solar storage tank. Failure to do so may cause a safety issue.
