- FUNCTIONS

FIRST FILL-UP:
- If the boiler and tank are completely emp-
ty, all system functions are disabled.
- Assure the presence of water in the tank,
and manually fi ll if empty.
- With the tank full and the boiler empty, after
feeding the generator through the switches
(see the "PREPARATION" paragraph), the
system controls the water fi lling pump until
the correct level is reached in the boiler. In
this phase the heater is deactivated.
Once fi lling is completed, the pump is tur-
ned off, and heating is simultaneously ena-
bled through the boiler heater.
Discharge any residual air from the boi-
ler during the heating stage, by pressing
switch 1 (fi g 15) and pressing the steam de-
livery button 5 (fi g. 17). This operation is im-
portant, given the power of the generator
to prevent excessive rise in pressure.
LEVEL ADJUSTMENT:
BOILER:
- Refi lling is carried out each time the level
probe senses a low water level in the boiler.
During normal level recovery, the heater
remains enabled for heating.
- If during fi lling the level probe located in
the tank should remain exposed, the sy-
stem immediately stops refi lling operations
and the signal lamp (2 fi g.6) starts blinking
together with an intermittent acoustic si-
gnal.
TANK:
- Each time the tank level probe senses a low
water level, the system immediately stops
refi lling operations and the signal lamp (2
fi g.6) starts blinking together with an inter-
mittent acoustic signal.
- Refi ll the tank to reset the alarm.

ALARM SIGNALS:

- If during the normal refi lling phase the boi-
ler level probe remains exposed for more
than 90 seconds consecutively, the heater
is temporarily deactivated and is reactiva-
ted at boiler level recovery since water re-
fi lling in any case continues regularly.
- WARNING! If during the normal re-
fi lling phase the boiler level probe
remains exposed for more than 3
minutes consecutively, the system
disables heating and refi lling functions, and
the signal lamp starts blinking along with an
acoustic signal. At this point the generator
must be reset by turning the general switch
off and then back on (1 fi g. 6).
IMPORTANT! AVOID THE USE OF
DISTILLED
WATER SO AS NOT TO JEOPARDIZE
THE EFFICIENT FUNCTION OF THE
GENERATOR.
