6.5.1 Electric heating

Before starting the machine, make sure that the level
of water in the boiler is higher than the minimum level
on the level-check window (1).
In some versions of the optical level is replaced by
a green light (3): the light is indicates the proper water
level of the boiler, slow flashes indicate the phase of
water loading.
If there is no water (first installation or after boiler
maintenance), it is necessary to fill the boiler in advance,
so as to prevent overheating of the heating element.
Proceed as follows :
SWITCH
Open the water supply tap.
Using manual fill (2) fill the boiler with
water until the optimal level is restored.
Turn the switch to position "1" and wait
for the machine to warm up completely.
MAIN SWITCH
Open the water supply tap.
Turn the main switch to position "1" (electrical power
supplied to the pump for automatic boiler filling and
machine services) and wait for the boiler to be auto-
matically filled with water;
Turn the main switch to position"2" (full
electrical power supplied, including the
heating element in the boiler) and wait
for the machine to warm up completely.

6.5.2 Gas heating
(if gas system is present)
Turn the main switch (A) to position 1;
open the gas valve (B) on the mains;
hold down the push button (C) and, at the same time,
press the on button (D). Once the flame ignites, hold
down knob (C) for a few seconds, to allow proper
activation of the thermocouple;
then check through the window (E) that the flame
has ignited;
wait for the operating pressure indicated on the pres-
sure gauge to reach the working value of 1-1.2 bar;

6.5.3 Electric + gas heating
(if gas system is present)
Proceed as indicated in the previous paragraph;
after checking that the flame has ignited, turn the
main switch (A) to position 2. In this way the boiler
heating element is powered and operating pressure
will be reached more quickly;
wait for the operating pressure indicated on the pres-
sure gauge to reach the working value of 1-1.2 bar;
during the machine's warm-up phase (roughly 20 minutes), the
negative pressure valve will release steam for a few seconds until
the valve itself closes.
Do not operate the gas plant when the boiler is empty.
6.5.4 Turning off the machine
Turn off the machine using the switch or the main
switch.
