MAINTENANCE REQUIREMENTS
MAJOR SERVICE EVERY FIVE YEARS
It is recommended a major service be conducted on the water heater every five (5) years. If an anode
replacement is conducted sooner than a major service, then the major service should coincide with the
replacement.
Warning: Servicing of a water heater must only be carried out by qualified personnel. Phone Rheem
Service or their nearest Accredited Service Agent.
Note: The major service and routine replacement of any components, such as the anode and relief valve(s),
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
Inspection and Replacement"
Check the system for correct operation.
Check the closed circuit fluid level.
Clean the collector glass.
Visually check the unit for any potential problems.
Inspect all connections.
Check the drain line from the safe tray (if one is installed) is not blocked.
Note: The solar storage tank may need to be drained during this service. After the completion of the service,
the solar storage tank will take some time to reheat the water by solar gain.
If this solar storage tank is installed with an integrated or remotely installed Rheem in-series continuous flow
gas booster, then for the booster's safe and efficient operation, it is recommended a major service be
conducted on the gas booster every five (5) years. Another type of in-series booster may have its own
recommended service schedule. Refer to the Owner's Guide and Installation Instructions supplied with the
booster water heater.
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. Rainfall should keep the collector adequately clean. It is recommended
the collector glass be washed clean at least every three months should adequate rain not have fallen in this
period.
Collector glass can be hosed down or if the solar collectors is accessible such as on a trafficable roof, wash
the collector glass with water and a soft brush when the solar collectors is cool, such as early in the morning.
In extremely dusty areas extra attention may need to be given to keeping the collector glass clean.
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 for the NPT200 and LCS
solar collectors to provide a level of protection to the collectors against vandalism or accidental damage.
Contact Rheem or your local Rheem Solar Water Heater Distributor for details.
