  • Page 4: About Your Water Heater

    The solar storage tank is suitable for either outdoor or indoor installation and can be installed with Rheem NPT 200, HBT 200 / LCS or TBT 200 / CSA2007 solar collectors. This single element model solar storage tank has only one front cover, located at the midpoint of the tank.
  • Page 5 ABOUT YOUR WATER HEATER Normal operation As the sun heats the water in the solar collectors, the increase in temperature activates the circulator. The circulator switches on whenever the water in the solar collectors is hotter than the water in the solar storage tank.

    Refer to setting Control” on page 8. minimum booster setting Rheem recommends the thermostat is set at 60°C to maximise solar contribution. maximum recommended Note: AS 3498 requires that a water heater provides the means to inhibit the supply growth of Legionella bacteria in potable water.
  • Page 7 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.
  • Page 8 ABOUT YOUR WATER HEATER BOOSTER CONTROL An isolating switch is installed in the electrical meter box for the solar storage tank. This should be left switched on to allow the booster heating unit to operate if required. The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy or rainy weather, or during the colder months.

    Note: The five year service and routine replacement of any components, such as the anode 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.
  • Page 14 Rheem Service or their nearest Accredited Service Agent. 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.
  • Page 15 REGULAR CARE FLUSHING THE SOLAR COLLECTORS It may be necessary to flush the solar collectors if there is sediment in the water supply. This should be conducted in the morning, within three hours of sunrise. Warning: It is important flushing of the solar collectors be conducted early in the morning, within three hours of sunrise, when the sun is low in the sky.

    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.
  • Page 17 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. Solar collectors in an open circuit solar water heater system should be covered when the water heater is not intended to be used for more than two weeks.
