Turning the controlling button counter-clockwise, the desired temperature can be
set at higher degrees, see Figure 4.
In case of failure of the controller, the reducing device saves the hot water tank
against damaging overheating in the way that before the temperature of hot water
stored reaches 110ºC-t, it breaks the circuit of the heating.
The reducing device should be switched on again only by a professional
technician, after eliminating the cause of the defect.
7.3 Heater
In case of failure of the compact heater, its replacement can be performed after
switching off the water tank from the electric system, fully emptying the water
tank, through removal of screws of the closing cover.
Its reparation can only be performed by a professional technician.

7.4. Active anode

As a supplementary accessory, the hot water tank is equipped with an active
anode to protect it against corrosion. The life expectancy of the active anode
depends on the conditions of water and operation. The state of the anode has to
be checked during periodic maintenance measures targeting scale removal or at
least in every second year.
The date of repeated check is defined by the repair technician. If the diameter of
the anode shrinks to 10 mm at any points, it has to be replaced.
The replacement of the active anode can only be performed by a contracted
service shop (see the commercial warranty!).
After the replacement of the active anode, its earthing has to be set
according to its original state. It is extremely important to ensure a good
metal contact between the active anode and the earthing screw.
IN CASE OF NEGLECTING THE ABOVE INSTRUCTIONS THAT CAUSES
DAMAGE TO SAFETY AND USAGE FEATURES OF THE HOT WATER TANK,
YOU LOSE YOUR GUARANTEE AND WARRANT RIGHTS.

7.5 Scale removal

Depending on the quality of the water, scale deposition may occur on the heater
or on the tank. The scale deposited on the heater increases the probability of
heater failure, so it has to be cleaned from scale in every second year.
The removal of scale is considered to be a maintenance activity, it is not part of
activities under guarantee.
As this activity required opening the electric fitting, the checks of the temperature
controlling/reducing device, the heater and electric connections should also be
performed in the same time.
THE CHECK CAN ONLY BE PERFORMED BY A CONTRACTED SERVICE
SHOP.
