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 .
