Safety relief valve
WH-ADC Hot water heater has two safety valves, one for
the (TANK) and one for the (CIRCUIT).
• The TANK's safety relief valve sometimes releases a
little water after hot water usage. This is because the
cold water, which enters the water heater, expands when
heated, causing the pressure to rise and the safety valve
to open.
• The CIRCUIT's safety relief valve must be completely
closed and must not normally release any water.
• The functioning of the safety relief valve should be
checked regularly. You can fi nd the safety valve behind
the inspection cover on the front.
Perform the checks as follows:
1. Open the valve.
2. Check that water fl ows through the valve.
3. Close the valve.
4. Check the system pressure, top up if required.
