SAFETY VALVE
The hot water coil's externally mounted safety valve
sometimes releases a little water after hot water usage.
This is because the cold water, which enters the hot
water coil, expands when heated causing the pressure
to rise and the safety valve to open.
The function of the safety valve must be checked regu-
larly. Perform checks as follows:
1.
Open the valve.
2.
Check that water flows through the valve.
3.
Close the valve.
TIP
The safety valve is not supplied with the accu-
mulator tank. Contact your installer if you are
unsure how one checks the valve.
