Warnings
1. The water supply must provide cold water for
human consumption (potable water) at a pressure
between 1,5 and 5 bars If the pressure is higher than
5 bar, connect a pressure reducer before the pump.
2. add a tap (15) to the water supply so as to stop
water from owing to the machine;
3. in order to prevent damage, it is advisable to
install the water purication lter where it will be
protected from accidental blows;
4. to prevent water from freezing, install the water
purification filter inside a premise with a room
temperature higher than 5°C;
5. if there is no water purication lter, connect the
water supply (12) directly to the inlet of the external
motor pump (13);
!
The water supply of the appliance must be
carried out with water which is suitable for
human consumption, in compliance with the
regulations in force in the place of installation.
The installer must receive, from the owner/
manager of the system, conrmation that the
water meets the above listed requirements.
In case of supply from the tank, do not use
carbonated water or other liquids.
!
The hydraulic connection must be made in
compliance with local national standards.
On lever machines, the hydraulic connection
should be made only to the water supply with
a minimum pressure of 1.5 bar. If an external
tank is used, the connection pipe between the
machine and the tank must not exceed 150 cm.
For the European Community: for the hydraulic
connection to the water mains and also for
connection to an external tank, it is necessary
to place a non-return valve (16) up the line from
the machine as set forth by standards EN 1717.
iAll lling connections are 3/8 male gas type.
The drain pan is connected to a tube with an
internal diameter of 16 mm.
iBefore install the machine please open the valve
of each ow meter (19).
i
In all machines equipped with automatic water
lling, there is an automatic time control device
which allows the boiler to be lled with water
within a maximum period of time. This function
keeps water from coming out of the valve of the
boiler (flooding) and keeps the motor pump
from overheating. If the maximum time is
not enough for the boiler to ll up completely
(machines installed with 3 or 4 groups), turn
the machine o and then back on, and repeat
the operations shown above.
3.2 Hydraulic connection
1. Remove the grids and drain pad (17);
2. remove the protection under the pad (18);
3. connect the water supply (12) to the water purication
lter inlet (10) using the provided exible hose;
4. connect the water lter outlet (11) to the external
motor pump inlet
(13) ;
5. connect the outlet of the motor pump (14) to the
inlet of the machine (7) ;
6. connect the drain pad of the machine (6) to the
sewer discharge
(5) using the special hose provided,
avoiding overly tight bends or kinks, and making sure
that there is sucient inclination for water to drain.
6. if there is an internal motor pump, connect the
outlet of the softener (11) (if there is one) or the
water supply (12) directly to the machine inlet (7);
7. when connecting the pad of the machine to the
sewer drain, avoid overly tight curves or kinks, and
make sure that there is sucient inclination for
water to ow out of the drain.
8. the drain must be connected to an inspectionable
syphon that can be periodically cleaned in order to
avoid the return of bad odours;
9. to avoid oxidization and damage to the machine
over time, do not use iron connections for the
hydraulic system, even if galvanized.

3.4 Wiring
It is necessary to link a safety main
switch (A) on the electric panel, as
required by standard regulations.
Machine with INTERNAL MOTOR PUMP
In case of internal motor pump connect the power
cable as set forth in the chapter "Electrical diagrams" (the
cable has a cross-section and number of wires based on
the power and voltage of the machine).
Machine with EXTERNAL MOTOR PUMP
In case of external motor pump, proceed as follows:
1. Connect the motor pump cable (with smaller cross
section) to the connector of the external motor as
shown in the diagram below.
2. Connect the machine power cable (with larger
cross section) as set forth in the "Wiring diagrams"
chapter.
A
!
Always connect the motor pump cable before the
machine power supply cable, in accordance with
the diagram provided. Failure to comply with
the instructions given above may cause serious
damage to the machine and/or motor pump
and will invalidate the warranty. Carry out the
electrical connections only when the machine is
disconnected from the power supply.
3.5 External motor pump adjustment
To adjust operating pressure proceed as follows:
• Operate a coee delivery switch;
• adjust the pressure by turning the screw located on
the pump (1) so as to
obtain a value between
8 and 9 bar: tightening
the screw increases
the pressure, and loos-
ening it reduces the
pressure. Check the
pressure on the display
() ;
• turn off the delivery
switch;
3.6 Machine tune-up
When installation is complete, the appliance has to be
started, brought to the nominal working condition and
left for 30 minutes in the "ready to operate" condition.
Afterwards, the appliance has to be turned o and
emptied of the first water introduced in the whole
hydraulic circuit, to eliminate possible initial impurities.
Then, the appliance must be once again loaded and
brought to the nominal working conditions.
After reaching the "ready to operate" condition, the
following has to be performed:
1. for each coee unit, carry out a continuous delivery,
in order to release the whole volume of water
contained in each associated coee tank;
2. release the entire volume of the hot water from the
boiler by continuous delivery through the specic
spout. In the case of several dispensing points,
divide the volume on the base of the number of
the dispensing points;
3. continuously release steam for at least 1 minute for
each steam dispensing point.
