6 - STARTING UP
Once the hydraulic, electrical and gas connections have been com-
pleted, the machine can be started up.
Open the water system tap (A).
Close the protection switch (D).
Place the main switch (3) on the position: the live machine war-
ning light will switch on (2).
The automatic level indicator will start filling the boiler with water
until it automatically reaches an intermediate position between the
MIN and the MAX level of the level indicator (23).
Once the automatic water filling operation has been completed,
place the main switch (3) on the position for normal power
operation, and on the position for maximum power operation,
thus supplying voltage to the water-heating element.
Then wait for the machine to reach the 1.1 – 1.3 bar operating
pressure, by checking the boiler pressure on the manometer (12).
Should the machine not settle on the indicated values, you will need
to set the pressure switch as explained in section 6.1.
When the machine is provided with a gas heating system, after
operating the main switch (3), you will need to switch on the gas, by
operating the gas valve (5) and pressing the piezoelectric igniter (6)
until the gas remains on.
Now check the pressure on the pump manometer (12), by starting
a unit with inserted filter-holder, filled with properly ground, dosed
and pressed coffee, so as to obtain the actual 8/9 bar operating
pressure.
Should you need to reset the pump pressure, you will need to follow
the directions listed under section 6.2.
The machine is now ready for use.
If the machine is not provided with an automatic level indicator, after
having placed the main switch (3) on the position, press the
manual boiler water filling button (9) to fill the boiler with water, and
keep it pressed untill the water level will have reached an intermedia-
te position between the MIN and the MAX level of the level indicator
(23).
Once the water filling operation has been completed, place the main
switch (3) on the position for normal power operation or on
the position for maximum power operation, thus conveying
voltage to the water heating element.
Regularly check the level of the water contained in the boiler, which
must not drop below the MIN level of the level indicator (23); if
necessary, top up to restore the required level by pressing the boiler
water filling button. (9).
Caution! Absence of water in the boiler while the
machine is running causes interruption of the resistan-
ce, which will have to be restored by an authorised
Assistance Centre.
During start up:
When the boiler pressure control manometer (12) displays a pressu-
re of approximately 0.5 bar, slowly open the steam tap (20), by
turning it anticlockwise, to discharge the air contained in the boiler,
and wait for the steam supply nozzle (11) to start producing steam,
before you close it again. Wait for the machine to reach the opera-
ting pressure and the correct thermal balance, within 35-45 minu-
tes.
ATTENTION:
Do not press the hot water supply switch or turn the
tap before reaching the correct 1.1 bar operating pres-
sure, indicated by the boiler pressure control manome-
ter (12).
6.1 - PRESSURE SWITCH REGULATION
The pressure switch shown in the picture is designed to maintain
the boiler pressure constant, by connecting or disconnecting the
electric heating element.
This pressure switch is adjusted during the final testing of the
machine on a 1.1÷1.3 bar value; however, should the specific
case require a different operating pressure, the pressure switch
operating range can be changed by operating the regulation
screw (U): by reducing the pressure, you obtain a temperature
reduction, whereas by increasing the pressure, the water tem-
perature also increases.
The regulation sense is shown in the picture and also on the
pressure switch itself.
Pressure varies by approximately 0.1 atm for each complete
turn of the screw.
Caution! Disconnect power supply before carrying out
this operation.
