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 “Expansion Control Valve” 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 “Solar Monitor” on page 10 and “Household Maintenance Around
the Solar Storage Tank” 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.
If this solar storage tank is installed with an integrated or remotely installed Rheem in-series 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 anode and relief
valves, are not included in the Vulcan 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 “Anode
Inspection and Replacement” 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.
