11.3. Descaling
Depending on the quality of water, scale
may deposit on the pocket tube of the
radiator and the tank, whereby descaling
should be performed every two years.
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 reassem -
bling using a new sealing . When cleaning,
avoid damaging the protective surface
finish.
Perform mechanical cleaning only; no
other cleaning or disinfection is needed .
Figure 11.3.-1
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).
11.4. Limiter
Since its replacement requires the disconnection of the electrical circuit, the con -
tainer must be powered off.
11.5. Radiator
Its replacement requires the disconnection of the power supply; such replace -
ment requires the disconnection of the electrical circuit.
The replacement of the ceramic heating element (radiator with pocket tube) re -
quires the discharge of water from the container and the removal of the service
cover. For this design, the radiator is inserted in an enamelled steel pocket tube
protected from outside impacts, whereby the heating element has not direct con -
tact with water. Due to this design, there is no failure due to scaling, the anode
has a longer expected service life than in conventional pipe radiator designs. We
absolutely recommend this design for regions where water is hard .
11.6. 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
