RAINWATER COLLECTION SYSTEM
If the 52H series solar water heater is installed on a section of roof which is part of a rainwater collection
system, then it is recommended this section of roof and its gutter be isolated from the rainwater collection
system.
The closed circuit fluid acts as an anti-freeze agent and rust inhibitor, is non-toxic to humans and is harmless
to the environment. However it does have an adverse effect on water stored in rainwater tanks. It will kill
microscopic algae typically present in rainwater tanks and cause an unpleasant odour to develop. This will
result in the rainwater tank having to be drained and cleaned.
If a rainwater tank does become contaminated with closed circuit fluid, then the following actions should be
undertaken by a qualified person. Additional actions may be necessary to return the water supply to a
consumable state.
•
Correct the leak or spillage.
•
Wash down the roof area where the spill or leak has occurred.
•
Flush out the gutters and down pipes.
•
Determine how the closed circuit fluid made its way into the rainwater tank. If the section of roof supporting
the solar water heater is not isolated from the rainwater collection system, then this should be remedied.
•
Empty the rainwater tank, and clean out all algae from the inside of the tank.
•
Refill the rainwater tank with fresh water.

TO TURN OFF THE WATER HEATER
If you plan to be away from home for a few nights, we suggest you leave the water heater switched on.
If it is necessary to turn off the water heater:
•
Switch off the electrical supply to the solar storage tank at the hot water isolating switch on the switch
board.
•
Close the cold water isolation valve at the inlet to the water heater.
TO TURN ON THE WATER HEATER
•
Open the cold water isolation valve fully at the inlet to the water heater.
•
Switch on the electrical supply to the solar storage tank at the hot water isolating switch on the switch
board.
•
Check and if required reset the timer, if one is installed.
GOING ON HOLIDAYS
If you plan to be away from home, conserve energy by switching the booster switch "OFF". Refer to
Off the Water Heater"
on page 15. Also if the system is not used for a period in excess of 2 weeks it is
recommended the solar collectors be covered.
Care should be taken when returning from holidays and the collectors have not been covered. The water in
the storage tank can be very hot.
