Preventative Maintenance
It is suggested for peak performance that the water heater be serviced annually.
1.
Check for discharge from the T&PR valve. Whilst the booster is off, and during periods
of low solar contribution there should be no discharge of water. When the booster is
operating or during periods of high solar contribution, a small discharge of water may
be evident. Operate the valve-easing lever to ensure the valve opens and resets
properly. Always open and close the valve gently. The T&PR valve should be replaced
at 5 yearly intervals.
2.
Check for leaks at the collector connectors, the hot and cold pipe, Sunstat valve and all
tank fittings.
3.
Check the condition of the insulation on the hot pipe.
Note:
In frost prone areas the hot
and cold pipes are insulated.
4.
Check the collector glass is not cracked and the absorber plate finish is not
deteriorating.
5.
Clean the collector glass. Do not stand on the collectors while cleaning.
6.
Check for signs of plant or tree growth that may be shading the collectors. Advise
customer to have pruned if possible.
7.
Isolate power
to the electric booster and check all electrical connections for signs of
overheating due to poor connection.
8.
Conduct an insulation test (Refer to page 16).
9.
Check for signs of roof sag or roof damage and advise customer to have rectified.
10.
Check for signs of excessive corrosion on the water heater jacket, collector panels and
roof stand if fitted.
11.
Confirm all supports and anchors retaining the system to the roof are present, firmly
fixed and in good condition.
