solenoid valve is excited until the set temperature
is reached or until the button is pressed again.
Safety Devices
Dispensing cannot be carried out if the machine has
not reached the operating pressure or temperature
at least once, and each time that the boiler pressure
drops too much.

● Wait for the machine to reach its working pressure
and to reach the correct thermal balance.
Models with gas (Fig.8)
● Turn on the water supply tap 2 (Fig.6).
● Turn on the gas tap 3 (Fig.6).
● Turn the main switch 1; the pump is activated, filling
the boiler.
● When the correct level is reached, the pump stops.
Turn the switch 2.
● Turn the gas tap 10 to the vertical open position and
hold down the incorporated button, at the same time
repeatedly press hard on the piezelectric button 11
until the spark lights the gas flame (carry out this
operation looking through window 14). Hold the tap
button 10 down for approx. 30 seconds to allow the
safety system to keep the flame lighted.If the flame
goes out, repeat the operation.
Should the flame not light up, avoid insisting
and close the gas tap by turning it 90° in a
clockwise direction.
● Wait until the machine reaches its working pressure
and until the correct thermal balance is achieved.

8. USE

The machine has a top shelf on which the cups are
kept and heated, ready for use.
This is very important to obtain good coffee as the
pre-warmed cup stops the coffee from growing cold
too quickly.

8.1. Preparing coffee

● Unclamp the filter-holder from the dispensing unit
and knock any grouts out into the drawer espe-
cially provided for this purpose, taking care not to
damage the rim of the filter.
● Use the filter for 1 or 2 coffees, according to need.
● Fill the filter with the measure of coffee, level it off
and press it down gently with the presser.
● Remove any ground coffee that has stuck to the
rim of the filter while pressing.
If ground coffee is left on the rim of the filter, a
leaktight seal is not ensured, with consequent
leaking of water and coffee grounds.
