effects on the water heater and its operation and/or life expectancy. If you are unsure of your water
quality, you can obtain information from your local water supply authority.
WARRANTY of this product is VOID where the product is installed in areas where corrosive water is
present or has been present in the product in the time span of the warranty. This product should only be
connected to a potable water supply.
Water that is corrosive to copper is typically associated with some bore water supplies of water not
treated by water authorities to ensure against copper corrosion. Corrosive water for copper can result in
premature failure of the product through hot water copper pitting corrosion where small holes develop
in the inner tank or copper coil and the product eventually leaks.
The following criteria shall be meet under the terms of the Warranty to ensure that water is not
corrosive or scaling to copper.
1.
pH is greater than 7.0 (pH > 7.0)
2.
Bicarbonate to sulphate ratio is greater than 2:1 (>2:1)
3.
Langelier Saturation Index (LSI) is greater than negative 1 and less than plus 0.8 (-1 <
LSI<0.8)
It is know that the following geographical locations provide water that does not always concur with the
above criteria and installation in these areas voids the warranty. Locations include suburbs supplied by
Redland Water, Wellington Point, Thornlands, Thorneside, Cleveland, Redland Bay, Point Lookout,
Ormiston, Mount Cotton, Alexandra Hills, Victoria Point, Birkdale, Capalaba, And Morton Bay
islands) and Bundaberg, Moore Park, Bargara and Yeppoon.
Notwithstanding the foregoing comment, this does not imply or infer in any way that the water
mentioned in the above locations does not meet drinking water requirements and is safe to drink.
NOTE:
WATER HEATERS NOT INSTALLED IN ACCORDANCE WITH THE ABOVE
ADVICE WILL NOT BE COVERED BY THE SOLARPOWER WARRANTY.
6.
ELECTRIC BOOSTING
Water stored in the storage tank is heated automatically by an electric booster heating unit. The
booster element heats the water during very cloudy or rainy weather, during the winter months, or
during periods of unusually high demand, such as when friends or relatives visit. The SolarPower
Solar water heater is suitable for the heating unit to be connected to continuous electricity supply.
The booster heating unit is controlled by an electric thermostat. The thermostat and heating element
are mounted on the solar storage tank inside the higher of the two covers. The boost water temperature
is automatically controlled to the thermostat setting when the booster heating unit is energised.
The thermostat is tradesperson adjustable. It has a minimum temperature setting of 60ºC and a
recommended maximum temperature setting of 80ºC. It can only be adjusted by an authorised person.
Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
SolarPower recommends that the thermostat be set at 60 ºC for the best efficiency.
The SolarPower Solar electric booster element will automatically heat the water in the tank.
