HyDRogen gas

In the case of systems using a vitreous enamel 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 water gets heated by the solar energy contributed from the sun and heats the water until the water at the
base of the storage cylinder reaches approximately 65°C� At this time water at the hot outlet can be up to 88°C�
Continued heating is prevented by the 'No Load' protection, a Thermo-arrestor (TA) valve that prevents water
passing from the cylinder to the collectors� During periods of low solar gain, supplementary heating occurs�
To meet Australian regulatory requirements, supplementary heating must be operational.
IMPORTANT

TuRnIng off THe WaTeR HeaTIng sysTeM
