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.
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.
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.
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.
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 power outlet to the water heater. 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. 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.
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).
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 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.
WATER SUPPLIES no warranty applies to a: temperature pressure relief valve or a water heater cylinder unless an expansion control valve is fitted. SATURATION INDEX (SI) STORAGE TANKS WITHIN WARRANTY SPECIFICATION -1.0 very corrosive 0 +0.4 SATURATION INDEX (calculated @ 80°C water temperature) scaling corrosive +0.8 very scaling SUMMARY OF WATER CHEMISTRY ADVICE AFFECTING WARRANTY The water heater, solar collectors and their components are not suitable for certain water chemistries.
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.
SAVE A SERVICE CALL 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).
SAVE A SERVICE CALL 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.

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.
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.
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.
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 6. 7. 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.
COMMISSIONING 11. Check the closed circuit fluid is circulating around the solar circuit. To check circulation: Listen for the trickling sound of the closed circuit fluid returning into the heat exchanger by placing your ear against the side toward the top of the solar storage tank. If the fluid is circulating around the solar circuit, a trickling sound will be heard as the fluid returns back into the heat exchanger.
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.
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.
COMMISSIONING 17. Determine the correct amount of water to be added to or closed circuit fluid to be drained from the heat exchanger if the dynamic level is either below the text marking “MINIMUM FLUID LEVEL WITH PUMP OPERATING” or more than 150 mm above this mark. Each 100 mm of fluid level height is equivalent to three (3) litres of closed circuit fluid. 20 mm 0.6 litres 80 mm 2.4 litres 140 mm 4.2 litres 40 mm 1.2 litres 100 mm 3.0 litres 160 mm 4.8 litres 60 mm 1.8 litres 120 mm 3.
COMMISSIONING 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.
