6. INSTALLATION

The appliance is only to be installed in
locations where use and maintenance is
restricted to trained personnel.
The machines are fitted with height adjustable feet.
The support surface shall be levelled, dry, smooth,
steady and stable and at such a height that the cup-
warming surface is at over 150 cm from ground. Do
not use water jets or install where water jets are
used.
In order to guarantee normal operation, the machine
must be installed in areas that the environmental
temperature is between +5°C ÷ +32°C end humidity
of not over 70%.
It does not need to be anchored to the surface and it
does not require any technical operations to dampen
vibrations in order to operate properly.
It is recommended to leave the area around the ma-
chine free to facilitate its use and the performance
of any maintenance operations.
If the machine is wet or very damp, wait until it is
completely dry before installing or using it. It is always
necessary to request an accurate control to qualified
service people in order to find any possible damage
to the electric components.
Reserve an area near the machine for the installa-
tion of the coffee grinding and dosage machine (see
relevant documentation).
The machine is usually equipped with a water sof-
tener, type DP2 or DP4, which must be connected
by the user in compliance with the laws in force.
Should a different softener be installed, refer to the
documentation of the relevant product.
A dreg drawer should be fitted by the installer.
6.1. Connections to be made by the
user.
Connections must be carried out by qualified
personnel in full accordance with federal,
state and local regulations.
6.1.1. Water and gas supply (Fig.5)
This equipment is to be installed to
comply with the applicable federal, state
or local plumbing codes.
Connections must be installed close to the machine.
1) Water drainage pipe 1, having a minimum internal
diameter of 30 mm, equipped with a water-trap
accessible for inspection.
2) Water supply pipe 2, with a 3/8"G cut-off tap.
3) Gas supply pipe 3, with a cutoff tap.
4) Main switch
5) Volumetric pump (if external to the machine)
6) Softener
Make sure that the maximum supply pressure
does not exceed 6.5 bar; otherwise, install a
pressure reducer.
The machine with gas heating must be instal-
led in compliance with current local laws.

6.1.2. Electricity supply

The machine is supplied ready for connection
according to the required electrical specifi-
cations.
Before connecting the machine ensure that the plate
details comply with those of the electric distribution
network.
The electrical connection cable must be directly
connected to the connection provided according to
current legislation. Ensure that the earthing system
is efficient and in compliance with current legal re-
quirements.
The earthing system and the lightening protection
system must be realized in accordance with the
provisions of current legislation.
For the supply network use a cable in compliance with
standards with protective conductor (earthing wire).
For three-phase power use a cable with 5 conductors
( 3 phases + neutral + earth).
For single phase power supply use a cable with 3
conductors (phase + neutral + earth).
In both cases it is necessary to provide an automatic
differential switch 4 (Fig. 5) at the start of the power
cable, complete with magnetic release elements in
accordance with the identification plate details (Fig.
1). The contact opening must be equivalent or over
3 mm.
Remember that each machine must be fitted with its
own safety elements.
WARNING:
Should the power supply cable be damaged
it is to be replaced by the manufacturer or by
its technical assistance service or by person
with equivalent qualification, in order to pre-
vent any risks.
6.2. Preliminary operations (Fig.6)
POTENTIAL-EQUALIZING CONNECTION
This connection, which is the one called
for by several norms, avoids electrical potential
differences, building up between any equipment that
may be installed in the same room. There is a terminal
clip on the under side of the base of the machine to
which an external potential-equalizing wire should
be connected.
This connection is absolutely necessary and must be
made right after the machine is installed.
Use a wire whose cross-sectional area conforms to
the existing norms.
