1.6 Important safety information

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 every 6 months to ensure its operation

and settings remain correct.

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, inﬁrm persons, or

persons lacking relevant skill or experience, without suitable supervision.

Children should be supervised to ensure they do not play with hot water taps or the

water heater.

If the hot water system 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 gas

safely, it is recommended that a hot tap be turned on for several minutes at a sink, basin

or bath but not 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.

1.7 If the customer is away for a long 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 high

temperature valve in the storage tank may open and disperse small amounts of hot water

for a short period to reduce the storage tank temperature while you are away. This is a

normal function and does not harm the system.

1.8 Water discharge through the pressure valve

All Conergy solar water heaters have two pressure valves located within the system

conﬁguration. The cold water expansion control valve (ECV), located in the cold water

supply pipe, may release a small amount of water from time to time during the heating

cycle of the system. The water discharge is water expanding due to the heating process.

Normally the discharge will be less than 10 litres per day. The pressure & temperature

valve, located on the storage tank, may also release a small expansion discharge.
