a) In order to avoid a blockage of the airing facility of the safety valve due to furring, the airing facility of the safety valve must
be operated from time to time during operation of the system. It must be observed whether the valve closes again after
releasing the airing facility and whether the water in place runs off completely through the funnel or the blow-off pipe.
b) In the case of safety valves that are installed ahead of water heaters, it must be observed whether the safety valve res-

Implementation: operator, plumber
Time interval: yearly
Maintenance and repairs:
If no penetration of water occurs during heating of the water heater or in the case of a constant leak of the safety valve, an
attempt must be made to loosen the valve by repeated operation of the airing facility or rinse out any possible foreign object
(e.g. fur particle) on the seal component.
If this cannot be achieved, then the appropriate repair by a plumber must be initiated. The complete safety valve must be
replaced in the case of any damages to the valve seat or sealing ring.
Implementation: plumber
Time interval: yearly
To test the non-return valve, the shutoff valve is closed and no water must run out of the opened test valve.

supply network in the case of a loss of line pressure, and thus protects the boiler from heating up without water. By means
of the shutoff valve, the storage tank can be separated in relation to water and thus also from the cold water supply network,
and emptied through the drain valve, if required.
This device is not designed to be used by persons (including children) with physical, sensory or mental disabilities or lacking
experience and/or lacking knowledge, unless these are supervised by a person who is responsible for their safety or have
received instructions on how to use this device from any such person. Children should be supervised in order to ensure that
they do not play with this device.

8. Decommissioning, Emptying U E
If a storage tank is taken out of operation or not used for a longer period, then it must be disconnected all-pole (in the case
of electric heating) from the electric power grid. Turn off the lead switch or, insofar as an auxiliary electric heating is installed,
the automatic cutout.
In rooms with a risk of frost, the water heater must be emptied before the start of the cold season, insofar as the device
remains out of operation for several days.
Caution: hot water may exit during emptying!
In the case of a risk of frost, it must be observed also that not only the water in the water heater and in the hot water lines
