Long Coffee Gigleur - Gaggia EVOLUTION E90 Mode D'emploi Et D'entretien

Once the water and electrical connections have been
made, proceed to start up the machine.
Open the mains water supply tap (A).
Close the protection switch (D).
Position the machine main switch (8) to position IT the
machine on indicator will come on (3).
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 supply tap (1) for a faster
operation.
Position the main switch (6) to position PN for operation
at normal power or to position PM for operation at full
power, thereby powering the resistances.
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 "Pressure switch adjustment".
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 "Pump pressure calibration".
The machine is now ready for use.
Do not press the hot
water delivery switch or
button (2) before the
correct
temperature of 1.1 atm is
reached, as indicated on
the boiler gauge (10).

The machine is fitted with a gigleur ( 1 per unit) with a
clearance 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 exchanger supply fitting (1 per
group).
