Storing and combined safety valve
In order to ensure safe operation, it is rational to turn to a plumber to check the
appliance and the correct operation of the combined safety valve every now and then
(in every year). Furthermore, it is recommended to blow off the valve every month or
every second month through turning the blow off button of the safety valve in the
direction indicated by the arrow. This way, the valve seat is cleaned from any
possible pollution (sand grains, scale, etc.)
10.6.
Active anode
The internal surface of the tank covered by enamel made of steel sheet, which
represents complementary protection against corrosion, is supported by active
anode. The life-cycle of the active anode depends on the quality and temperature of
the water. In case of water of lower temperature, the extent of active anode
diminution is less.
Your appliance is equipped with the up-to-date active anode status display.
Until when the signal lamp of the hot water tank lights with green color, the active
anode ensures secondary corrosion protection of the tank. As soon as the active
anode fails to perform its corrosion protection task, the color of the signal lamp turns
into yellow color, then into red color. In this case, a professional electrician has to be
contacted to mount a new active anode into the appliance. It is extremely important to
mount the electronics of the active anode display and the signaling anode in a
professional way.
IN CASE OF NEGLECTING THE ABOVE INSTRUCTIONS THAT CAUSES
DAMAGE TO SAFETY AND USAGE FEATURES OF THE APPLIANCE, YOU
LOSE YOUR GUARANTEE AND WARRANT RIGHTS.
10.7.
Scale removal
Depending on the quality of the water, scale deposition may occur on the
heater exchanger or on the tank. The scale deposited on the heater decreases
heating efficiency. So, it is necessary to clean the hot water tank from scale every
second year.
It is strictly forbidden to apply any sharp metal object or acid to remove scale
deposited on the heat exchanger, the close cover and its fittings. Please use cleaning
and scale removal supplies available in commerce.
Scale can be removed from the interior part of the tank manually, through the
fitting opening. It is rationale to flush the tank with water ray after scale removal.
10.8.
Prevention of frost damages
If temperature may fall below the freezing point in the location of the hot water
tank, the heating of the tank must not be switched off or the tank must be discharged
in periods of frost danger.
10.9.
In case of indirect heating
OVERHEATING PROTECTION MUST BE PERFORMED BY THE INDIRECT
HEATING EQUIPMENT!
10.10.
Air filter
Clean the air duct every month as this influences heating
performance!
If the filter has been mounted directly into air inlet (i.e. air inlet is not
connected to air duct), dismounting and cleaning of the filter can be performed in the
