Major five year service
It is recommended a major five year service be conducted on the water heater. The service must be
conducted by a qualified person.
Note:
The five year 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 should include:

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 anode.
If the anode is not replaced at this time it should be inspected regularly from this time.

Check the electric heating unit for excessive calcium build up or corrosion and replace if
necessary.

Check and inspect the heat pump module for operation.

Visually check the unit for any potential problems.

Inspect all connections.

Check the condensate drain.

Check the drain line from the safe tray (if one is installed) is not blocked.
Note: The water heater may need to be drained during this service. After the completion of the
service, the water heater will take some time to reheat the water. Depending upon the power
supply connection, hot water may not be available until the next day.
Heat pump system
It is recommended the evaporator and refrigeration system is checked every five years. In
particularly dusty environments, it may be necessary to have the heat pump system checked and
cleaned of dust and residue on a more regular basis.
