Once the water, gas and electrical connections have been
made, proceed to start up the machine.
Open the mains water supply tap (A) (fig 2).
Close the protection switch (D) (fig 2).
Position the machine main switch (8) to position
machine on indicator will come on (3).
The auto-levelling device will come into operation so that the
7
water reaches a normal level in the boiler (12).
Position the main switch (6) to position
at normal power or to position
power, thereby powering the resistances.
14
Wait for the pressure to reach its operational pressure
15
1.1¸1.3 atm checking the boiler pressure on the gauge
(10).

Should the machine fail to stabilize on the indicated values
18
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,
1
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 (10) 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.
The machine is now ready for use.
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).
6.1 Long coffee gigleur
The machine is fitted with a gigleur ( 1 per unit) with a clea-
rance of 0.6 mm (Cod. WGA26G0074/01).
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.
WGA26G0073/01). The gigleur is located in the exchan-
ger supply fitting (1 per group).
