the system connection to the water supply network and the tank is filled with water; during the
use of the tank not less frequently than once every 14 days; and after each stop of water
supply. It is therefore recommended that the combined valve be installed in an easily accessible
place. The use of the device with defective combined valve is strictly prohibited. Immediately
turn off the power supply of the water heater and contact the nearest authorized service center.
Otherwise, it will cause a default on the tank and possibly cause other damages.
10. Where necessary the safety valve may serve for draining the water from the tank. The
procedure is as follow:
Switch off the appliance from mains with the optional device and even for greater safety
disconnect the fuse protecting phase circuit.
Close the cold water access to the unit – close the tab on pos. 4 of Fig. 12.
Open the hot water tab of the mixing tab or disconnect the hot water outlet pipe from the water
heater.
Lift up the combined valve lever and wait until water stops to run from the valve.
These steps secure complete draining of water from the tank. The operation may be carried out
only by qualified person because it requires disconnection of the appliance from mains and
removal of the flange water tank.
WARNING!
IT IS ABSOLUTELY PROHIBITED TO SWITCH ON POWER SUPPLY TO THE
SYSTEM WHEN THE WATER TANK IS PARTIALLY FILLED OR EMPTY OF WATER!
Before putting the system back in operation do not forget to fill the water tank with water –
please refer to section

.
WARNING!
When draining water all precaution for damages from outflow water must be put in
place.

12. When operating and maintaining the appliance pay special attention to protect the metal
plate with appliance data and manufacturer (serial) number. In case of accidental removal from
