of the water network, and the cold water tap, but leave the hot water tap open
throughout the time of discharging .
9.3. Descaling
Depending on the quality of water, scale may deposit on the radiator and the
tank . Scale depositing on the radiator increases energy consumption and the risk
of radiator failure, whereby descaling should be performed every two years . Since
intensive scaling may cause damage to the heater, check the radiator for integrity
too . Descaling requires the emptying of the tank, the disconnection of the electri-
cal circuit and the removal of the service cover . After removing the service cover,
it is recommended to perform reassembling using a new sealing . When cleaning,
avoid damaging the protective surface finish .
Descaling is considered to be part of the maintenance, and it does not belong to
the activities covered by guarantee . However, due to the necessity of disconnect-
ing the circuit, putting back into operation must be performed by an authorised
service station (along with the review of the electrical connections) .
9.4. Regulator, limiter
Its replacement requires the disconnection of the power supply; such replace-
ment requires the disconnection of the electrical circuit . The regulator and the
limiter form a single unit .
9.5. Radiator
A radiator of 1200W power is installed in the left tank, and one of 800W (7 .d) is
installed in the right tank .
In case of failure, the replacement of the radiators requires disconnection
from the electrical network and the discharge of water, as well as the remov-
al of the bolts in the service cover . THE REPAIR MUST BE PERFORMED BY A
PROFESSIONAL.
9.6.

Active anode

The hot water storage tank is additionally protected against corrosion by active
anodes . The service life of the active anodes is subject to the water quality and
the operating conditions . The condition of the anodes must be checked upon
each descaling operation, but at least once every two years .
Its replacement requires the disconnection of the power supply; such replace-
ment requires the disconnection of the electrical circuit and the removal of the
service cover . After removing the service cover, it is recommended to perform re-
assembling using a new sealing .
The technician determines the time of the next inspection . If the diameter of the
anode decreases by 10 mm anywhere, it must be replaced . After replacement
of the anode, its earthing must be implemented according to the original state .
Adequate metal-through connection between the active anode and the earthing
bolt is essential .
9.7. Defrosting
Taking the appliance out of service requires the removal of power, and the total
emptying of the container .
