Installation Instructions
for the “MASTER” Model
Master Version: LCD, rel. 4.1
CAUTION: RISK OF POLLUTION.
Do not dispose of packaging in the environ-
ment.
Before carrying out any installation and
adjustment operations, the qualified techni-
cian must put on work gloves and protective
footwear, as well as be sure that he/she has
read and fully understood the safety instruc-
tions in this handbook.
After checking that the box of accessories
is contained in the packaging, position the
machine as required and ensure that it is
perfectly level, adjusting the feet if neces-
sary.
Place the water softener into the compart-
ment provided. Please remember that for all
versions of the MASTER machine, the
pump is fully incorporated making all con-
nection operations much simpler.
Before connecting the machine to the plum-
bing system, it is necessary to flush the
water softener thoroughly to eliminate any
impurities and greasy deposits.
At this point, the qualified member of staff
shall carry out the connection to the plum-
bing and electrical system, as shown in
Figures 4 - 5.
The qualified member of staff must, if the
electric cable supplied is not suff i c i e n t ,
always use another of the same section.
Check that the mains power supply has an
efficient grounding system, which should be
connected to the machine using the green
and yellow wire.
CAUTION: RISK
OF SHORT CIRCUITS.
We would like to remind the qualified elec-
trician that THE MACHINE MUST A LWAY S
BE PROTECTED WITH AN A U TO M AT I C
SWITCH WITH SUFFICIENT P O W E R
(220 - 240V/12A).
The company cannot be held responsi-
ble for damage to things or injury to per-
sons caused by failure to comply with
the safety instructions and installation
and maintenance instructions contained
in this handbook (we remind you that
the above operations must only be car-
ried out by qualified staff).
For the correct functioning and long life
of your machine, we recommend that
you install a water softener and filter (no
wider than 150 microns) to the inlet tube.
Make sure that there are at least 2 bars
of pressure and if this is not so, adjust
the hot water mixer accordingly. To gain
access to the mixer, remove the right
hand side panel of the machine.
Mixer adjustment: when releasing hot
water, use the central knob over the boi-
ler, moving it slightly to vary the tempe-
rature of the water as it leaves the
machine.
Furthermore, water supply pressure
should not exceed 4 bars. If this is not
the case, fit a pressure reducer
upstream of the water softner.
CAUTION: RISK
OF SHORT CIRCUITS.
Before connecting the machine to the
mains power supply, please check that the
supply voltage corresponds to the machine
voltage (see the technical characteristics on
page 26).
Connect the machine to the power supply.
In the Master/Cappuccino version, the refri-
gerator will start up automatically.
