IMPORTANT INFORMATION & WARNINGS
Gas boosted models
•
Do not touch the flue outlet or do not insert any objects into the flue outlet.
•
Keep flammable materials, spray cans, fuel containers, trees, shrubs and pool
chemicals etc. well clear of the flue outlet.
•
Do not use the gas types other than those designated on the data plate. For
example, do not use Propane/Butane gas mixtures on appliances marked Propane
Gas.
•
Do not use Propane gas on appliances marked as Natural gas and vice versa.
Hydrogen Gas
In the case of systems using a vitreous enamelled lined cylinder, if the hot water unit is not used for two weeks or
more, a quantity of hydrogen gas, which is highly flammable, may accumulate in the water heater. To dissipate this
safely, it is recommended that a non electrically operated hot tap be turned on for two minutes at a sink, basin, or
bath, but not a dishwasher or other appliance. during this procedure there must be no smoking, open flame or any
electrical appliance operating nearby. If hydrogen is discharged through the tap, it will probably make a sound like
air escaping.
WATER TEMPERATURE
The solar control unit and pump ensure water circulates between the solar collectors and storage cylinder until the
water at the base of the cylinder reaches approximately 65°C. Under these conditions water at the hot outlet may
exceed 85°C. During periods of low solar gain supplementary heating occurs to a minimum of 60°C as required.
To meet Australian regulatory requirements, supplementary heating temperature settings
must be at least 60°C.
IMPORTANT
TURNING 'OFF' THE WATER HEATING SYSTEM
If you plan to be away for only a few nights, we suggest you leave the water heating system switched on. If it is
necessary to switch off the water heater, do so as outlined below:
Electric Boosted systems
•
Switch off the electric supply to the supplementary heating element. The switch is usually marked and
located in the electricity meter box of the dwelling.
•
Switch off the electric supply to the solar controller and pump.
Gas Boosted systems
•
Switch off the electric supply to the gas booster.
•
Switch off the electric supply to the solar controller and pump.
TURNING 'ON' THE WATER HEATING SYSTEM
Electric Boosted system
•
Switch on the electric supply to the supplementary heating element(s). The switch is usually marked and
located in the electricity meter box of the dwelling.
•
Switch on the electric supply to the solar controller pump. Electric and solar water heating will now occur as
required. It may take a number of hours before hot water is available.
Gas Boosted systems
•
Switch on the electric supply to the gas booster.
•
Switch on the electric supply to the solar controller and pump. Solar water heating will now occur. Hot
water is available immediately from the gas booster when hot water tap is opened, irrespective of solar
heat gain.
