Note:
The solar storage tank may need to be drained during this service. After the completion of the service,
the solar storage tank will take some time to reheat the water by solar gain. Depending upon the power supply
connection to the booster heating unit, hot water may not be available until the next morning.
HOUSEHOLD MAINTENANCE AROUND THE SOLAR STORAGE TANK
Care should be taken when conducting general household maintenance, such as lawn mowing and grass
cutting, around the solar storage tank. Careless use of devices such as a whipper snipper could damage or
cut a sensor lead or the electrical cable.
If a sensor lead or the electrical cable is damaged or cut, solar contribution may not be achieved and the freeze
protection system may be rendered inoperative. In addition, if the electrical cable has been damaged or cut,
wiring may be exposed leading to a dangerous situation.
On a regular basis, inspect around the water heater for insect infestations, such as ants. Insects may look for
a warm place to nest, particularly in wet weather. Insects encroaching into or nesting in the water heater and
the solar control unit can interfere with the operation of the water heater and also damage components. Spray
insecticide around the base of the water heater if necessary to rid the area of insects.
COLLECTOR GLASS
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
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 such as on a trafficable roof, 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 extra attention may need to be given to keeping the collector glass clean.
Have any trees trimmed which may shade the solar collectors.
Solahart solar collectors have passed the AS/NZS 2712 requirements for resistance to hailstone damage, so
it is not normally necessary to fit a guard to a collector. Stone Guards are available to provide a level of
protection to the collectors against vandalism or accidental damage. Refer to your local Solahart Dealer for
details.
