INITIAL COMMISSIONING
Before switching on the electrical power the storage tank must be filled with water.
During the heating up process the expansion water generated in the inner boiler must drip out of the safety
valve in the case of a pressure resistant connection and out of the mixer unit in the case of a non-pressure
connection.
Warning: the initial heating up process must be carried out and monitored by a licensed profession-
al. The hot water drainage pipe as well as parts of the safety fittings can get hot.
After heating up the configured temperature and the actual temperature of the extracted water should be
about the same.
DECOMMISSIONING, DRAINING
If a water heater is put out of action or remains unused for a lengthy period then it must be drained and
completely isolated (at all poles) from the power supply. Switch off the supply line switches or automatic
circuit breakers.
In rooms permanently subject to frost damage, the water heater must be drained before the start of the
cold weather season if the device will be out of action for several days and is not being operated in frost
protection mode.
The draining of the domestic water is carried out once the shut-off valve has been closed in the cold water
feed via the drainage valve of the safety valve combination whilst all hot water valves of the connected op-
erating mechanisms are simultaneously open. It is also possible to drain the system via the safety valve in
the excess water funnel (drip tray). In order to do so the safety valve knob is turned to the "Test" position.
Careful: hot water can escape when draining.
In addition, where there is a risk of frost, it is important to note that not only the water in the water heater
and warm water pipes can freeze, but that the water in all the cold water pipework leading to the operat-
ing mechanisms and to the device itself can freeze too. It is therefore useful to drain off all water-carrying
fittings and plumbing right back to the frost protected part of the household water system (household
water connection).
If the storage system is brought back into service then it is crucial to ensure that it is filled with water and
that bubble-free water emerges at the hot water valves.
