containersand the recyclableones mustbe recoveredby
qualified companies.
Important notice!!
The machine should be positioned with a maximum incli-
nation of 2°.
CONNECTING THE MACHINE
TO THE WATER MAINS
Some models can be connected to the drinking water
mains, taking into account law provisions in force in the
country where the machine is installed.
Thewaterpressuremustbe7.3to123.3psig(0.5-8.5bar).
Runsomewaterfromthemainsuntilitisclearandwithout
impurities.
Useahose(alsoavailableasakit)capableofwithstanding
the water mains pressure and suitable for use with food-
stuff (min. inside diameter of 6 mm) to connect the water
supply to the union (3/4" gas) of the water inlet solenoid
valve (see Fig. 15).

OVERFLOW DEVICE
The water inlet solenoid valve (see Fig. 15) is equipped
with an overflow device which mechanically stops the
waterinlet ifthere isamalfunction inthe solenoidvalve or
in the boiler water level control device.
To restore normal operation, proceed as follows:
- drain the water contained in the overflow hose;
- shut off the water supply using the tap outside the
machine;
- loosen the connection which secures the solenoid
valve supply hose to relieve the water mains residual
pressure and then tighten it again (see Fig. 15);
- open the tap and switch the machine on.
CONNECTING THE MACHINE TO THE
POWER SUPPLY
Themachineisdesignedto operateunderasingle-phase
120 V~ voltage and is protected by 15 A fuses.
Before making the connection, ensure that the rating
corresponds to that of the power grid, and more specifi-
cally:
- the supply voltage rating must be within the range
recommended for the connection points;
- the main switch should be capable of withstanding the
peak load required, and at the same time ensure
proper omnipolar disconnection from the power grid
with an opening gap of the contacts of at least 3 mm.
The switch, the power outlet and the plug must be
located in an easily accessible position, so that the
cable can be disconnected in the event of interven-
tion..
Thepowersupplycableisofthetypewithafixedplug.Any
replacementofthepowersupplycable(seeFig.16)should
be made by qualified personnel only, using cables of the
type UL SJTO 3x16 AWG.
Theelectricalsafety ofthe machine isensured onlywhen
it is correctly earthed according to the safety standards in
force.
This fundamental safety requirement must be duly
verified, and if in doubt the system must be carefully
tested by qualified technicians.
Do not use adapters, multiple sockets and/or exten-
sions.
Before switching the machine on, be sure it is correctly
connectedtothewatermainsandthecut-offvalveisopen.
