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.

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, thoroughly wash the mains water
pipes:
● Leave the water supply taps running at full pres-
sure for several minutes.
● Connect to the mains water supply.
● Connect the machine up to the power supply
mains.
● Connect the gas pipe
Thoroughly wash all the water pipes of the machine:
● Leave the water supply taps running at full pressure.
● Switch on main switch (pos.1 - Fig.7): wait until
the boiler fills up to the level set. (mod.CLUB
switch )
● Switch on boiler resistance switch (pos.2 - Fig.7)
to begin heating the water in the boiler. (mod.
CLUB switch )
● 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 installation tech-
nician MUST issue an installation report.

7. SETTING UP

7.1. Controls (Fig.7)
1 Main switch.
Three-position switch:
0 off;
1 activates the pump to fill the boiler;
2 turns on the whole machine and activates the
heating elements.
1A Two-position switch with led.
Turn on the switch, led on, the machine is turned
(apart from the boiler) and the pump is turned on
to fill the boiler;
1B Boiler resistance switch.
Two-position switch with led.
On activating the switch, the led comes on, and
power is supplied to the resistance for the boiler
water.
2 Green pilot lamp.
When on, indicates that machine is powered (main
switch on).
3 Coffee dispensing switch.
Two-position switch with led:
turn on the switch, led on, coffe is dispensed;
turn off the switch, led off, dispensing of coffee is
interrupted.
4 Electronic coffee delivery button panel.
6 buttons with relative led:
A pressing on this key, will light up the relative LED,
the dispensing of one strong coffee will start.
B ppressing on this key, will light up the relative
LED, the dispensing of one long coffee will start.
C pressing on this key, will light up the relative
LED, the dispensing of two strong coffees from
the same group will start.
D pressing on this key, will light up the relative
LED, the dispensing of two long coffees from the
same group will start.
E press this key; coffee is continuously dispen-
sed.
Once the dispensing cycle has finished, all the
LEDs will light back up again.
To stop a dispensing under way started, press the
same button activated or button E STOP
5 Hot water supply handwheel.
Tap: turn a antclockwise to open and clockwise
to close.
6 Dose of hot water supply switch (mod. ME).
Press the button to obtain the delivery of a dose
of hot water.
7 Steam supply handwheel.
Tap: turn in an anticlockwise direction to open and
clockwise to close.
