2.3.4 Electrical connection
Only qualifi ed and properly trained personnel can operate on the electric board and connections.
Before the installation:
Make sure that the voltage is the same as reported on the data-plate.
Make sure the line voltage matches the machine power and voltage indicated on the machine data-plate (as shown on par.
1.1
).
Electrical connection must be carried out in compliance with the current local standards.
Use the data reported on the data-plate to check dimensions and electrical connections.
The machine has a terminal on the back panel indicated by the symbol
that is meant to link the metal structures
of diff erent appliances, to prevent electro-static shocks (see electrical safety standards).
IMPORTANT:
connect the clamp to other appliances.
To dimension supply cables and switches, please refer to the maximum power expressed in Watts (W) and Amperes (A)
specifi ed on the machine serial number plate.
Feed cable:
the retailer - importer - installer must ensure that the feed cable complies with the cable insulation category of
the workplace, in conformity with current Technical Standards.
2.3.5 Steam evacuation
In accordance with regulations of environmental hygiene, for the proper functioning of the machine and a healthy environment
for the operator who working in there, it should be at least 10 air volume changes per hour in the room where the machine
is installed.
For small wash rooms we recommend at least 15 air volume changes per hour.
2.4 Installation
2.4.1 Positioning the machine
Remove the packing with care.
Lift the machine as described in par.
2.1.1 Handling the product
.
Position the machine as shown on the installation diagram (lay-out) approved at the
time of the off er.
Maintain a minimum distance of about 50 mm from the walls, so that motors are ventilated
(see pict. 5). Install suction hoods to assure proper ventilation of the room, in order to
eliminate steam and excessive humidity.
Check that the machine is properly levelled, by adjusting the legs (see pict. 6).
Make sure the machine is not standing on the power cable or on the fi lling/drain hoses.
Level the machine fl at, by adjusting the support feet.
The electrical supply cable must be new, fl exible, and according to "har" H07RN-F or a
local valid equivalent. The cable size is dimensioned according to the power.
50 mm

WARNING:
check very carefully if the “ground connection” of the machine is properly sized and fully effi cient,
and that not too many units are connected to it. An undersized or poor “ground connection” might lead to
corrosion and/or pitting eff ect on the stainless steel plates, even to perforation.
It is necessary to install a suitable omni-polar automatic fuse switch sized according to the absorption
that assures the complete disconnection from the network in an overvoltage category III condition.
This switch must be incorporated in the supply network, dedicated only and exclusively to this circuit
and installed in the immediate vicinity.
The machine has to be absolutely turned off by this switch: only this switch gives the full warranty of
complete detachment from the electric network.
Make sure the appliance is linked to an effi
cient ground connection.
