Safety valve
The safety valve must be inspected regularly.
Ease the safety valve lever slightly to release some water through the overow pipe. This must be carried out at least 4 times a
year. It is quite normal for the safety valve to let out small amounts of water when the water tank is being charged.
• If the valve does not work satisfactory, it must be replaced.
• If there is a risk of freezing, the water heater must be drained.
• In the event of malfunctions - contact the installer.
