• An incorrect installation can cause damages to persons, animals or things, towards which the manufacturer
cannot be held responsible.
• Train the operator on the position of the switch so that it can be quickly reached in case
of an EMERGENCY.
• To guarantee a regular functioning, it is necessary that the maximum voltage variation is
between +/- 6% of the nominal value and that no odd harmonic distortions are present.
• Check that the power supply line has opportune section cables and, however, not lower
than 2.5 mm² and that it is protected against over-currents and earth dispersions in
accordance with legislation.
• For very long power supply lines, adequately increase the cables section to compensate the relative
voltage drop.
5.8 Electrical connection - remote condensing unit
in case a standard external condensing unit is supplied, the technician will have to connect the power supply of such
unit to the display cabinet. The operation is simplied in that, inside the display cabinet base,
behind the removable grate of the equipment compartment, a terminal board is present on which
a white derivation box, which can be opened like a book, is xed.
On such box (PA 104) there are 5 clamps which names are marked on the same box cover with
the following symbols: L N G 1 2.
L N G = Is the display cabinet power supply, respectively phase, neutral and
earth 230 Volts, 1Ph, 50Hz.
1 2 = Is the motor power supply 230 Volts, 1Ph, 50Hz.
5.9 Hydraulic connection
The appliance is supplied standard without condense drying tank (optional), it
is therefore necessary to connect the defrosting water discharge pipe (or pipes)
with the premises water network discharge.
ATTENTION! For correct functioning, it is necessary to interpose a siphon between
the appliance discharge and that of the water network.
Should a condensing unit completely or partially cooled through water be present,
it is necessary to connect the ingoing pipe (recognisable by the presence of thermal
insulation) to the discharging one, of the water-cooled condenser to the water
network. (Fig. 5.9)
