12. Initial Commissioning
The storage tank must be filled with water prior to switching on the electrical power.
Any expansion water which arises in the internal boiler during the heating up process with a pressure
resistant connection must seep out from the safety valve.
Warning: The initial heating-up process is to be carried out and monitored by a specialist from
the dealer. The hot water outlet pipe and parts of the safety valve/fittings can become hot.
13. De-commissioning, Draining
If a hot water heater should be out of operation or not be used for a long period of time, then it should
be drained and disconnected from the main electricity supply at all poles.. Switch off the connecting
switch or automatic circuit breakers.
In rooms that are at risk from frost for long periods, the hot water heater should be drained before the
commencement of the cold time of year, if the equipment should remain out of operation for several
days and not be operated in the frost-protection setting (see Point 6).
The draining of the domestic hot water is carried out after closing the shut-off valve in the cold water
supply line by the draining valve of the safety valve combination whilst at the same time opening all hot
water valves of the connected fittings that are used. Draining is also possible via the safety valve in the
expansion water funnel (drip pan). For this, the small wheel on the safety valve should be rotated to the
„Prüfen“ („Test“) setting
Warning: Hot water can escape during the draining process
If there is a risk of frost, you should furthermore be aware that not only the water in the hot water heater
and in the hot water pipes can freeze but also the water in all of the cold water supply lines to the valves
and fittings that are used as well as in those on the equipment itself. It is therefore advisable to drain off
all water-carrying valves and fittings and pipes back as far as the frost-protected part of the domestic
water installation (domestic water connection).
If the storage tank is put back into operation, it is essential to ensure that it is filled with water
and that bubble-free water is emitted from the hot water valves.
