6. INSTALLATION OF THE INTERNAL UNIT
6.6 Electrical supply
Electrical connections have to be done by qualified personnel, by observing
the current rules in the place where the air conditioner unit has to be
installed. Electrical connection has to be preceded by a careful control
about compatibility between the electrical supply line and the features of
the unit you want to connect.
In the electrical supply line of the unit it is mandatory to foresee a bipolar
switch ( a differential one) with a contact separation of at least 3mm in
every pole.
Attention!
Before doing any work on the units, make sure that the main electrical
supply has been disconnected.
Before interrupting the power supply by means of the switch, turn the air
conditioner off with the remote control.
Connect earthing wire.
Earthing wire should not be con- nected to the gas pipe,
water pipe, lightning rod or phone line, incorrect earthing
may cause shock.
6.6.1 Preliminary checks
- Check that the electrical system, intended for the air conditioning, has
voltage and frequency corresponding to that required by the unit.
- Check that the electrical power available to the user is insufficient to
operate the air conditioning and other electrical equipment present.
6.6.2 Power supply of the units
For al models, power supply is moved to external unit.
Please use an exclusive source of electrical power for the air conditioner
only, with a dedicated magnetothermic switch /differential
Alimentation
Magnetothermic switch
Nota:
Single Hi-Wall models are already equipped with electric power cable,
a length of 1.8 m.
6.6.3 Power cords and connecting
- All the feed and connection cables must be approved in conformance
with IEC standards, and for lengths up to 15m., must have a section
not less than:
Model
XECO-0715W
XECO-0915W
XECO-1215W
XECO-1815W
XECO-2415W
- Use a multi-pole cable of type N07RN-F
- For lengths over 15m, use the next higher standard section, always
checking that in every case the voltage drop during operation is lower
than 3% of the supply voltage.
- If a cable is damaged it must be replaced by service personnel or by
qualified personnel.
- All cables must have the certificate of conformity.

between the units
- Provide to use a protection sheet for the cables exposed to the outside.
- It is recommended to set the cables with a drip-proof run in order to
avoid possible infiltrations of water in the outdoor unit.
- Combine the electrical connection cable of the two units to the refrigera-
tion piping and wrap with reinforced tape, possibly alluminized (Fig. C).
- If the cable cannot be solid with the piping, make a suitable wall ancho-
rage by means of a cable fastener or hose clips..
