MAINTENANCE REQUIREMENTS
MINOR MAINTENANCE EVERY SIX MONTHS
It is recommended minor maintenance be performed every six (6) months. Minor maintenance can be
performed by the dwelling occupant.
The minor maintenance includes:
•
Operate the easing lever on the temperature pressure relief valve.
It is very important the lever is raised
and lowered gently.
Refer to
on page 8.
Warning:
Water discharged from the temperature pressure relief valve drain line will be hot. Exercise
care to avoid any splashing of water by standing
clear of the drain line’s point of discharge when operating
the valve’s easing lever.
•
Operate the easing lever on the expansion control valve (if fitted).
It is very important the lever is raised
and lowered gently.
Refer to
on page 8.
•
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 19.
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 SERVICE EVERY FIVE YEARS
It is recommended a major service be conducted on the water heater every five (5) years. If an anode
replacement is conducted sooner than a major service, then the major service should coincide with the
replacement.
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 valve(s),
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 21).
•
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.
