MAINTENANCE
Minor Six Month Maintenance
It is recommended minor maintenance be performed every six months by the dwelling occupant.
The minor maintenance includes: 1) If accessible, 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 9.
!
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.
If the temperature pressure relief valve is not readily accessible, contact your local Solahart Dealer.
2) Operate the easing lever on the expansion control valve. It is very important you raise and lower the lever gently. Refer to“ Expansion Control Valve” on page 9.
Major Service
This major service should be performed to coincide with the anode replacement OR at five years, whichever is sooner( refer to the Anode Replacement Period section). Only genuine replacement parts should be used on this water heater.
THE MAJOR SERVICE CAN ONLY BE CARRIED OUT BY A QUALIFIED PERSON. CONTACT YOUR LOCAL SOLAHART DEALER OR AUTHORISED SERVICE REPRESENTATIVE.
The major service addresses the following aspects: |
1) |
Check the closed circuit fluid level( Closed Circuit Series only). |
2) |
Replace the temperature pressure relief valve( Part No. 45-1104). |
3) |
Flush the cold water relief valve( Part No. 45-1103). |
4) |
Where fitted, check the electric element for excessive calcium build up or corrosion. Replace if necessary. |
5) |
Visually check the unit for any potential problems, e. g. broken glass, excessive dust build-up, shading etc. |
6) |
Carefully inspect all connections. |
7) |
Drain and flush out tank sediment build-up if required( see“ To Empty the Water Heater” on page 54). |
8) |
Drain and flush collectors(‟ L ‟ Series only)( see“ To Empty the Water Heater” on page 54). |
9) |
Replace the anode. |
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.
For units fitted with a tempering valve or a water softener, the operation should be checked at this time. These checks are not covered within the major service.
Anode Inspection & Replacement
Corrosion protection of the water heater ‟ s tank is obtained by using two coats of high quality vitreous enamel and the use of a sacrificial anode.
The anode installed in your water heater will slowly dissipate whilst protecting the cylinder. The life of the cylinder may be extended by replacing the anode. The following table shows the when the anode should be replaced.

Water quality details should be obtained from the water authority where special water supplies are used. Generally, where the water is supplied from a bore or well, the quality of the water will be such that a three-year anode change( or less) will be required. A water analysis is recommended for these locations.
