2 – MACHINE INSTALLATION
2.1 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.
2.2 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 locations where temperatures
range between +5°C and +32°C and humidity
does not exceed 70%.
If the machine is exposed to temperatures below
+0 °C, proceed as follows:
- ensure that the machine has spent 24 hours
in a location where the temperature is above
+15°C before switching it on.
The machine is powered by electricity and it needs
the following to operate:
- connection to mains electricity.
2.2.1 Connection to mains electricity
Warnings:
- The connection to mains electricity must be
done by qualified personnel.
- The wiring must be done in compliance with
current laws and earthed.
The machine is supplied with a power cord fitted
with a plug. For a permanent connection to the
mains between the appliance and the mains, fit
an omnipolar safety switch with a minimum open-
ing between the contacts of overvoltage category
III sized for the load that complies with the current
standards.
2.2.2 Water supply mode (TOP versions only)
The machine is delivered in tank mode; to convert
the supply to mains mode, follow the water supply
connection instructions first (see paragraph 2.2.2)
Warnings:
The conversion from TANK mode to MAINS mode
or vice-versa involves a variation of pressure,
produced by the rotary pump. This pressure can
be adjusted as described in section 6.5 of this
manual.
2.2.3 Connection to drainage circuit
Connect a rubber hose (Fig.03 Pos.13) with an
internal diameter of 10 mm from the fitting on the
machine's drain to a previously prepared open
siphon drain.
2.2.4 Flow regulator installation (for PID
version only)
Before using the flow regulator, it is necessary to
assemble the knob and pressure gauge supplied
(Fig. 16).
Position the knob on the appropriate pin making
sure that it is parallel to the knobs of the hot water
and steam taps; tighten the rear screw using the
spanner supplied (Fig. 15)
Unscrew the screw on the body of the dispens-
ing group using the appropriate spanner supplied
(Fig. 16) and screw in the pressure gauge using
one or two gaskets to place it in the correct posi-
tion
3 - MAINTENANCE
Follow the maintenance instructions indicated be-
low to operate the machine correctly.
3.1 Safety rules
Do not use water jets on the machine. Discon-
nect the machine from the power line by turning
the lever of the omnipolar disconnecter, of the
electric mains, to the "0" rest position, remove the
plug and close the water interception valve before
carrying out maintenance and/or cleaning opera-
tions. If the machine malfunctions, do not attempt
to repair it yourself and immediately contact tech-
