First Commissioning; Decommissioning, Emptying - Austria Email SISS 350 Instrucciones De Uso

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-
ponds during heating of the water heater. This is identifiable by the penetration of water out of the blow-off pipe.
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.
The storage tank is operated by the hot water valve of the service fitting (mixer tap). Therefore, the storage tank is constantly
under line pressure. In order to protect the internal boiler from overpressure during heating, the appearing expansion water
is discharged through the safety valve. The non-return valve prevents the hot water from flowing back into the cold water
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.

7. First Commissioning

The storage tank must be filled with water before being put into operation for the first time!
The expansion water created in the internal boiler during the heating process must drip from the safety valve in the case of
a pressure-proof connection, and from the overflow mixing tap in the case of an unpressurised connection.
Caution: the hot water drain pipe as well as parts of the safety fitting may become hot thereby!

8. Decommissioning, Emptying

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
can freeze, but also in all cold water supply lines to the service fittings and to the device itself. Therefore, it is advisable to
empty all fittings and lines holding water (also heating circuit = register) back to the frost-safe part of the domestic water
system (domestic water supply).
If the storage tank is put back into operation, then it must bindingly be observed that it is filled with water and water
exits bubble-free at the fittings.
