MAINTENANCE
SAFETY VALVE
The safety valve (FL1) must be inspected regularly, about
4 times a year, to prevent clogging. The check is made
by turning the safety valve's knob anticlockwise, water
should then flow through the overflow pipe. If this does
not happen then 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 expansion of cold water entering the water heater,
resulting in a pressure increase, whereby the safety
valve opens.
EMPTYING

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

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

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.
