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
Inspection and Replacement” on page 12).
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 a remote in-series Rheem continuous flow gas booster, then for the
booster’s safe and efficient operation, it is recommended a five year service be conducted on the gas booster.
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.
