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 15.
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 15.
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
on page 11 and
on page 16.
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 your nearest
Solahart Dealer.
Note:
The five year service and routine replacement of any components, such as the anode and relief
valves, are not included in the Solahart 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 18).
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.
