urning on the machine
4.1 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). 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 :
• Open the water tap of the water mains and of the softener.
• Turn the switch to position "1" (electrical power supplied to the
pump for automatic boiler filling and machine services) and wait
for the boiler to be automatically filled with water;
• Turn the switch to position"2" (full electrical power supplied, in-
cluding the heating element in the boiler) and wait for the machine
to warm up completely.
• 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
i
• before using the machine, run deliveries dry with the filter holder attached for a few seconds to
release any air which may be in the circuit, so that the delivery groups are completely heated
• before using the machine, dispense a few servings of coffee to test the grinding and to check the
operating pressure of the machine
4.2 Gas heating
(if there is a gas system)
• 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 activa-
tion of the thermocouple;
• then check through the window (E) that the flame has
ignited;
• wait for the operating pressure indicated on the pressure
gauge to reach the working value of 1-1.2 bar;
