[4] Safety thermostat
8.2.3 Periodic cleaning
▶ Turn off all hot water taps.
▶ Inform all residents of the danger of burns.
▶ Position the thermostat on the maximum position, by
turning temperature knob clockwise until it stops (
Fig. 11, [4]).
▶ Wait until the indicator turns off.
▶ Open all the hot water taps, starting with the nearest one to
the furthest one from the appliance, and purge all the hot
water from inside the appliance, at least 3 minutes.
▶ Turn off all the hot water taps, and position the thermostat
on the normal working position.
8.2.4 Long standing - non working (more than 3 months)
▶ Switch off the electric current to the appliance.
▶ Drain the appliance completely.
▶ Fill the appliance until the water comes out from all the hot
water taps.
▶ Turn on the appliance to the electric current.
8.3 Safety thermostat
The appliance is equipped with an automatic safety
thermostat. If for any reason the water temperature inside the
appliance exceeds the safety limit, the switch will trigger and
cut all electric current supplying the appliance, thus avoiding
any accidents.
8.4 Inside of the tank
The storage of water at high temperatures and the
characteristics of the water itself can cause a layer of scale to
build up on the surface of the electric heater and/or the
accumulation of detritus in the interior of the tank, affecting
mainly:
• water quality
•power consumption
• appliance functionality
•appliance service life
Amongst other things, the abovementioned consequences
lead to a lower thermal transfer between the heater and the
water, causing the thermostat to start/stop more frequently,
higher power consumption and potential safety activation if
temperature limits are breached (manual resetting of
thermostat necessary).
DANGER: Burn risk!
During the periodic cleaning process the hot
water may cause serious burns.
▶ Carry out this operation outside working
hours.
After a long period of inactivity you should
change the water inside the appliance (more
than 3 months).
DANGER: The reactivation of the appliance
should only be done by an authorized
technician!
The action to manually re-start or reactivate
should only be done once the cause of which
initiated this action has been identified and
rectified.To reactivate the device:
▶ Press the button firmly (Fig. 14, [4]).
If the safety thermostat is activated on a
frequent basis:
▶ ensure more regular cleaning of the
electric heater.
