The auto-levelling device will come into operation so that the water
reaches a normal level in the boiler (12). Also press lever of water

Wait for the pressure to reach its operational pressure 1.1
÷1.3 atm
checking the boiler pressure on the gauge (10).
Should the machine fail to stabilize on the indicated values it is
necessary to calibrate the pressure switch as described in paragraph
6.2.

In the event of a machine featuring a gas heating system, it is
necessary to switch on the gas by operating the gas valve (4) after
operating the main switch (6), keeping the piezoelectric switch
pressed (5) until the gas remains on.

Then check the pressure on the pump gauge (11) putting a unit into
operation with filter holder engaged filled with ground, dosed and
pressed coffee in order to achieve an effective working pressure of
8/9 atm.
Should re-calibration of the pump pressure be necessary this
operation should be undertaken as indicated in paragraph 6.3.

LONG COFFEE GIGLEUR
The machine is fitted with a gigleur ( 1 per unit) with a clearance of
0.6 mm (Cod.26G0074/01).

For greater coffee delivery speed, in the case of long coffees, no.2
gigleurs are also included with the machine (complete with seals)
with a clearance of 0.8 mm (Cod.26G0073/01).

The gigleur is located in the exchanger supply fitting (1 per group).
IMPORTANT
Do not press the hot water delivery switch or button (2)
before the correct working temperature of 1.1 atm is
reached, as indicated on the boiler gauge (10).
