6.1.1. Water supply (Fig.5)
This equipment is to be installed to
comply with the applicable federal, state
or local plumbing codes.
Make sure that the maximum supply pressure
does not exceed 6.5 bar; otherwise, install a
pressure reducer.
Connections must be installed close to the machine.
● Water drainage pipe 1, having a minimum internal
diameter of 30 mm, equipped with a water-trap
accessible for inspection.
● Water supply pipe 2, with a 3/8"G cut-off tap.
Water supplies to the machine must be suitable for
consumption by man and for human uses, in com-
pliance with all the laws in force in the installation site.
The installation technician is required to get confirma-
tion from the final owner and/or user of the system
that the water meets all the foregoing requirements.
For machine installation it is necessary to use all the
components and/or parts supplied on issue with the
machine. Should it ever be necessary to use other
parts and/or components, the installation technician
is required to verify that said other parts and/or com-
ponents are suitable for contact with water for human
consumption/drinking water. The technician in charge
of installation is required to perform all the hydraulic
connections so that they are totally compliant to all
the related rules, regulations and provisions in force
in the installation site on hygiene, hydraulic system
safety and environ¬mental protection.
6.1.2. Electric supply (Fig.5)
The machine is supplied ready for connection accor-
ding to the required electrical specifications.
Before connecting the machine ensure that the plate
details comply with those of the electrical main sup-
ply.
The electrical connection cable must be directly
connected to the connection provided according to
current legislation.
The earthing and the lightening protection system
must be realized in accordance with the provisions
of current legislation.
For the main power supply be sure to use cable that is
compliant with all local, state and federal regulations
and be sure that it is properly earthed.
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 ac-
cordance with the identification plate details (Fig. 1).
The contacts must have a 3mm or greater opening
with a dispersed current protection of 30mA.Remem-
ber that each machine must be fitted with its own
safety elements.
WARNING:
Should the machine's power cable become
damaged it is to be replaced by the manu-
facturer or by a factory trained and certified
technician, in order to prevent any risks..

6.2. Preliminary operations (Fig.6)

EQUIPOTENTIAL CONNECTION

This connection is ABSOLUTELy NECES-
SARy and must be made right after the machines
is installed.
Connect an earthing wire to the terminal clip which is
located underneath the base of the machine.
Be sure that this wire and the connection are per-
formed in accordance with federal, state and local
regulations.
6.3. Installation and first-time start-
up
● Position the machine unit onto the horizontal sur-
face provided for that purpose and adjust the base
feet to ensure that the machine is stable and that
vibrations are limited.
Before connecting the machine, thoroughly flush the
main water supply pipes:
● Open the main water supply taps and let the water
run at full pressure for several minutes.
● Connect to the main water supply.
● Connect the machine up to the power supply
mains.
Thoroughly flush all the water pipes of the machi-
ne:
● Leave the water supply taps running at full pres-
sure.
● Switch on main switch 1 (Fig.7): wait until the boiler
fills up to the set level
● Switch on boiler heating elemen switch 2 (Fig.7)
to begin heating the water in the boiler.
● Once standard machine work conditions have been
reached with the machine in "ready for operation"
mode, switch the machine off and empty all the wa-
ter filled into the water circuit the first time, thereby
eliminating any possible initial impurities.
● Fill the machine up with water again and set it into
standard operation mode.
● Once the "ready for operation" status is reached:
- Connect the filter-holders to the dispenser units
(without coffee); operate each group head in
order to allow the water to escape for about one
minute.
- Dispense hot water until at least 2 liters of water
have been dispensed from the 1-group or 2-groups
compact, 5 liters from the 2-groups machines, 8
liters from the 3-groups machines and 11 liters
from the 4-groups machines.
- Open each steam dispensing point for 1 whole
minute.
Once installation is terminated, the installa-
tion technician MUST issue an installation
report.
