All water heaters have the ability to produce hot water very quickly. To reduce the risk of scald
injury, it is recommended that a temperature control valve be fitted to the hot water supply pipe
work. This valve should be checked at regular intervals to ensure its operation and settings
remain correct.
Please check that the pressure & temperature relief valve drain pipe is not located where it can
cause damage if hot water is discharged.
This water heater is not intended for use by young children or infirm persons without supervision.
Young children should always be supervised to ensure that they do not play with hot water taps
or the water heater.
If you are away for a period of time
If the system is not to be used for a period of a week or more during the summer months,
it is advisable to turn off the electricity supply to the booster and if practical cover the solar
collectors. If the solar collectors are not covered, there is a possibility that the pressure &
temperature relief valve in the storage tank may open and disperse small amounts of hot water
to reduce the storage tank temperature while you are away. This is a normal function and does
not harm the system.
Water discharge through the pressure valve
All Conergy solar water heaters will have either one or two pressure valves in the water pipe
work:
1. A Pressure & Temperature Relief Valve attached to the tank, and possibly;
2. A Cold Water Expansion Valve located in the cold water supply pipe work.
For solar water heaters that only have a Pressure & Temperature Relief Valve, it is normal for
a small water discharge to occur during the heating cycle of the system. This discharge is
water expanding due to the heating process. Normally the discharge will be less than 10 litres
per day. For systems that have both valves, the expansion discharge will occur from the Cold
Water Expansion Valve.
Hydrogen gas can accumulate!
If the hot water system is not used for two weeks or more, a quantity of highly flammable hydrogen
gas may accumulate in the water heater. To dissipate this gas safely, it is recommended that
a hot tap be turned on for several minutes at a sink, basin or bath. Do not use a dishwasher,
clothes washer or other appliance. During this procedure there must be no smoking, open
flame or any other electrical appliance operating nearby. If hydrogen is discharged through the
tap, it will probably make an unusual noise as with air escaping. Do not place hands or any part
of your body beneath the tap during this procedure.
