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 14.
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
on page 14.
Check the drain line from the safe tray (if one is installed) is not blocked.
Check the status of the LEDs. The green LED should be illuminated (either solid, pulsing or flashing). The
red LED should be off. Refer to
“Household Maintenance Around the Solar
on page 15.
It is important to ensure the solar controller and circulator are operating correctly, particularly at the onset
of the colder winter season. Solar gain will not be achieved and the freeze protection system will be
rendered inoperative if the solar controller or circulator are not operating.
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 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.
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 anode.
If the anode is not replaced, it should be replaced within three years of this service (refer to
on page 17).
Check the electric heating unit for excessive calcium build up or corrosion and replace if necessary.
Check the solar control unit for correct operation.
Flush and bleed the solar collectors.
Clean the collector glass.
Check the insulation on the solar hot and solar cold pipes. If required, insulate exposed pipe work and
repair or replace degraded insulation.
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. Depending upon the power supply
connection to the booster heating unit, hot water may not be available until the next morning.
