All maintenance operations and service visits should be performed by a competent
person (who have the skills required by the applicable norms in force).
Before performing any maintenance operations and/or replacing any components,
disconnect the appliance from the electricity mains using the external switch;
empty out the water heater if necessary.
See warning nos. 20 - 26 - 28
To access the electrical parts (heating element, thermostat, pilot lamp), remove the
cover C by unscrewing screws D (fig. 4).
In the event of an intervention on the thermostat, disconnect the latter from the electricity
mains and slide it out of its seat on the heating element. In the event of an intervention
on the heating element, unscrew the bolts (A fig. 6) using a 10 mm spanner.
When remounting the components, make sure you put the flange seal, the thermostat,
the heating element and all pipes back in their original position.
We recommend you replace the seal each time you dismount the flange.
Once the aforementioned operations are complete, make sure you fill the appliance
with water before powering it.
The following operations should be performed annually:
-
empty the appliance and dismount the heating element;
-
carefully remove all limescale from the heating element parts; if you prefer not to use
acids designed especially for this purpose, use non-metallic objects to break off the
limescale crust that has formed, taking care not to damage the heating element’s
armour.
-
We recommend you replace the seal each time you dismount the heating element.
To remount the heating element, the tightening torque of the bolts (A fig. 6) should be
between 7 and 10 N/m. You must respect the “criss-cross” type of tightening.
Once the aforementioned operations are complete, make sure you fill the appliance
with water before powering it.
Replacing parts, when necessary
Periodic maintenance
!
Resetting the bipolar safety
In the event of an abnormal overheating of the water, a thermal safety switch in
compliance with CEI-EN norms cuts off the electrical circuit on both the power supply
phases of the heating element.
To reset the operation of the appliance, proceed as follows:
-
leave it to cool;
-
set the knob (F fig. 6) to the maximum temperature position;
-
remove the cover C by unscrewing screws D (fig. 4);
-
disconnect the thermostat (T fig. 6) from the electricity mains;
-
using a cross-head screwdriver, press on point A fig. 9 until you hear it click.
Remount everything in the reverse order, paying particular attention to repositioning
the components correctly.
Once the aforementioned operations are complete, make sure you fill the appliance
with water before powering it.
