It is recommended minor maintenance on Unvented Systems (systems with TPR valves) be performed every six (6) months.
Minor maintenance can be performed 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
“TPR Valve”

.
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)
If an expansion control valve is installed operate the easing lever on the expansion control valve. It is very important

The major service addresses the following aspects:
1)
Pressure Relief Control:
a.
Unvented Systems - replace the TPR valve (Part No. VN0262002K), OR
b.
Vented Systems - check the Vent Pipe for damages, excessive calcium build up. Replace Vent Pipe if necessary.
Check any supports, ties or clamps holding the Vent Pipe in an upright position.
2)
Where fitted, check the electric element for excessive calcium build up or corrosion. Replace if necessary.
3)
Visually check the unit for any potential problems, e.g. broken glass, excessive dust build-up, shading etc.
4)
Carefully inspect all connections.
5)
Drain and flush out tank sediment build-up if required (see

in the Solahart warranty. A charge will be made for this work. Only genuine replacement parts should be used on this water
heater.
If a temperature limiting device, water filter or a water softener are installed, their operation should be checked at this time.

SYSTEM DECOMMISSIONING
Decommissioning of the system should be undertaken by a suitably qualified person(s). All materials used in this product can
be passed to your local material recycling centre for disposal - refer to local council regulations for details.
COLLECTOR CARE
Ensure the glass on your solar collectors is free of dust, salt spray or any other matter which may reduce the effectiveness of
the solar collectors. Rainfall should keep the collector adequately clean. It is recommended that the collector glass be washed
clean at least every three months should adequate rain not have fallen in this period. Collector glass can be hosed down or if
the solar collectors are accessible, wash the collector glass with water and a soft brush when the solar collectors are cool,
such as early in the morning. In extremely dusty areas, more frequent washing may be necessary.
Have any trees trimmed which may shade the solar collectors.
