E fig. 5; take off the bracket close-flange S, then with nippers hold the Z
nut and then press on the flange G into the inside.
At this moment the flange can be taken away with a semicircular movement
as shown on fig. 4. During the reassembling phase, fig. 4, make sure that
the positions of the gasket, of the flange are the original ones referred to
in fig. 5.

Periodic
maintenance In order to obtain performance from the appliance it is advisable to scale
off the heating element R fig. 6 about every two years, depending from
the hardness of the water.
If one does not wish to use suitable acids, the operation can be carried
out by crumbling the limestone crust making sure not to damage the
covering of the heating element.
The magnesium anode, N fig. 6 must be replaced every two years.
To remove it dismantle the heating element and unscrew the anode from
the bracket.
Bipolar
safety
reactivation In case of abnormal water heating, a thermic safety switch, according to
the CEI-EN regulations, breaks the circuit in both feeding fases to the
heating element; in this case it is better to call the Technical Assistance.
Safety valve In those moels equipped with a safety valve with a lever, the latter can be
used, by lifting it up, to:
- empty out the appliance, if necessary
- check on a regular basis (every month) that the valve is operating
correctly.
Useful hints
(user) 1) If hot water does not come out from the taps, before calling the Technical
Assistance, make sure that the water and electric links are as specified
in the relative paragraphs, or make sure of the continuity of the phases
between the clamps and the relative fastons on the thermostat, after
taking it to pieces. In a negative case one can presume the intervention
of the bipolar safety (call the Technical Assistance).
2) If the warning light does not light up, but hot water still comes from the
apparatus, possibly it is only a faulty bulb.
For the replacement of the warning light bulb one takes away the
thermostat (unscrewing the two fixing screws), disconnects the connection
fastons L fig. 5 and slips out the bulb P from the thermostat seat; insert
the new bulb and reassemble the thermostat.
3) For the water heater’s galvanic protection system to function properly.
The permanente hardness of the water should not be less than 12
°
fr.
During the normal functioning of the appliance, the connections could
become hot.
Starting As already said the starting is carried out moving the switch F fig. 7 from
position O to position I.
For models which are not fitted with a switch, provide electrical power by
turning the control knob in a clockwise direction.
The warning light remains on only during heating phase.
The thermostat will automatically disconnect the heating element when
the selected operating temperature is reached.
