4 - MACHINE INSTALLATION
4.1 Warnings
Installation must be carried out by qualified per-
sonnel, according to the instructions supplied by
the manufacturer and in compliance with current
laws.
The machine must be positioned and installed
in a place where use and maintenance are per-
formed exclusively by qualified personnel. The
machine can be used in places set up for staff
kitchen areas in shops, offices and other working
environments; holiday farm houses; by clients in
hotels, motels and other types of accommoda-
tion; bed and breakfast settings; etc.
4.2 Preparation of system for
installation
Place the machine on a flat, horizontal, even, dry,
smooth, sturdy, stable surface positioned at such
a height that the cup warming surface is over 150
cm from the ground.
Do not use water jets or install in places where
water jets are used.
To ensure normal operation, the appliance must
be installed in places where the temperature is
between +5°C and +32°C and the humidity
does not exceed 70%.
If the machine is exposed to temperatures below
+ 0 °C, proceed as follows:
- ensure that the machine has passed 24 hours
in a place where temperature is higher than +
15 °C before turning it on.
The machine is powered by electricity and it needs
the following to operate:
- connection to mains electricity.
- connection to drainage circuit.
4.2.1 Connection to mains electricity
Warnings:
- The system must be created in compliance with
current laws and earthed.
The machine is supplied with an electric power
cord fitted with a plug.

4.2.2 Water supply mode
The machine is delivered in tank mode. To con-
vert the supply into mains mode, first follow the
water connection instructions (see section 4.2.3)
then select the water MAINS mode from the set-
ting menu (see section 5.13)
Warnings:
keep the parts necessary for closing the supply
connection in the event that it is decided in the
future to use the TANK mode only.
The conversion from TANK mode to MAINS mode
or vice-versa involves a variation of pressure, pro-
duced by the rotary pump. This pressure can be
adjusted as described in section 4.3 of this ma-
nual.
4.2.3 Connection to the mains
network (MAINS mode)
In case of conversion from tank supply to water
mains supply before opening the water shut-off
valve upstream of the machine connection, remo-
ve the tank and insert the plug (Fig. 10, Pos. 1)
into the water supply fitting under the tank.
Make sure that the water supply line is connected
to a drinking water network with operating pres-
sure between 0 and 6 bar (0 - 0.6 MPa).
If the water network has pressures above 6 bar
(0,6 MPa), install a pressure reducer.
Install a water shut-off valve upstream of the ma-
chine's connection.
The water inlet pipe (Fig. 03; pos. 4) is supplied
threaded with G 1/8" threading.
4.2.4 Connection to drainage circuit
Connect a rubber pipe (Fig. 03; pos. 12) with an
internal diameter of 10 mm to the connection,
provided on the machine's drain well, to a pre-
viously prepared open syphon drain.
