MAINTENANCE
SAFETY VALVE
The safety valve (FL1) must be inspected regularly, about 4
times a year, to prevent clogging. Check by turning the
safety valve’s knob anticlockwise, water should then flow
through the overflow pipe. If this doesn’t happen, the safety
valve is defective and must be replaced.
The safety valve sometimes releases a little water after hot
water has been used. This discharge is caused by the expan-
sion of cold water entering the water heater, resulting in a
pressure increase, whereby the safety valve opens.
EMPTYING
1. Turn off the power to the water heater.
2. Shut off the cold water inlet with valve QM35).
3. Loosen the cover of the drain valve (QM3) and install
the supplied hose connector and hose.
4. Turn the drain valve (QM3).
5. During draining, air must be let into the water heater by
loosening the hot water heater connection (XL4) or
opening a hot water tap. In order to ensure the complete
emptying of the water heater, the hose connection must
be completely tight and the outlet must be below the
lowest point of the water heater.
NOTE
The hose must exit below the water heater’s lowest
level.
Water splashes may occur at the overflow pipe.

When installed in a location that is exposed to the risk of
frost, the water heater must be emptied whenever it is not
in operation. Freezing will result in the water heater bursting.
