5 – FIRST USE OR REUSE
Follow carefully the instructions before using the machine.
• open the external packing and take the machine out. Inspect the
machine to ascertain that it is intact and in good condition. Check
for the presence of all the accessories supplied with the machine
(see paragraph 4)
• position the machine on a flat surface
• remove the cover and take out the water tank (2) (located inside
the machine) and rinse it
• fill the container with clean water, return it to its housing and
insert the silicon tubes. Close the cover on the machine.
The machine PRO2BPID offer the versatility of use with water tank
(2) or with connection to the water supply, using the appropriate
pipe supplied (17). (SEE PAR. 5.1)
To use the machine with water tank (2) the switch (Z) has to be in
position I (operation to be performed with the machine off).
To use the machine with connection to the water supply,the switch
(Z) has to be in position II (operation to be performed with the
machine off).
Removing the cap (W) from the tray and connecting the silicon
tube (25) to the pan (Y) you can download directly into the water
drainage pipe. (see FIG.2)
5.1 - WATER SYSTEM
Caution! The machine must be supplied with water
having a hardness above 8°F degrees.
It is advisable to install a water softener for the machine water
system. Ensure that you will be connecting the machine to drinka-
ble water mains.
The connection to the water supply of the machine must be in
accordance with the country of destination.
The pressure of water entering the machine must not exceed
0,65Mpa
- Connect the hose (17) to the connector (X) located under the
machine and then connect it to the water mains.
- As far as the mains pressure is concerned, if this exceeds 0,5Mpa
(5bar), it is advisable to install a balanced pressure reducer for
high pressure (a device whereby any mains increase does not
affect the output pressure).
5.1.1 ELECTRICAL CONNECTION AND FIRST TURNING ON OF
THE MACHINE
WARNING! Before making the electric connection,
make sure that the main power voltage corresponds
to the specifications indicated on the data plate placed
under the base of the machine.
Before putting into operation the machine, insert the filter holder
(12) in the brewing group (11); put a tank under the delivery
group and move the lever (15) upward to allow the filling of the
coffee boiler.
Press the main power switch (1). Wait about 2 seconds to allow
the circuit to perform a control check. The pilot light (14) will be
switched on. To use the machine connected to the water network,
position the switch (Z) on II (operation to be performed with the
machine off).
The automatic level indicator will start filling the boiler with water
until it automatically reaches the prescribed level; the boiler water
level is automatically checked and the prescribed level will be
automatically refilled.
As soon as the water leaves the delivery group (11) move the lever
(15) down in order to stop the supply.
Wait the filling of the automatic level in the boiler which is confir-
med by the lighting of the termopid (26).
Wait that the service boiler's reaches the set up temperature (92°)
and then start with the boiler firing putting the switch (28) on the
position “ I” the boiler light (29) will be switched on.
Then wait until the machine reaches the 1.1 – 1.3 bar operating
pressure, by checking the boiler pressure on the pressure gauge
(5).
The Termopid (27) has been set by the producer of this machine
on a tempe-rature of 122°C.
N.B. The machine with a basin built-in is provided with
a safety device controlling the amount of water contai-
ned in the basin itself; the green light (14) flashes to
indicate the lack of water in the tank (2) and the device
automatically cuts off all machine functions.
As it is filled up, the warning light switches off and the
machine is ready again to deliver coffee.
WARNING ! The coffee brewing and the power supply
of the heating element don’t work when the water
tank lamp (14) flashes.
During start-up: when the boiler pressure gauge (5) shows a
pressure of approximately 0.5 bar, open slowly the steam tap
handle (7), to discharge the air contained in the boiler, and wait
until steam starts flowing out of the steam supply nozzle (10), then
close it.
5.2 PRESSURE SWITCH REGULATION
The pressure switch shown in the picture has to keep the pressure
in the boiler constant, by activating or deactivating the electrical
heating element.
This pressure switch is adjusted during the final testing of the machi-
