6. INSTALLATION OF THE INDOOR UNIT
Connecting the pipes to the fittings
- Connect the pipes to the fittings on the unit.
-Secure by tightening the nuts to a torque of:
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.
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
6.5 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 cont

Unit power supply
The power is brought on the outdoor unit.
Use a power source for the exclusive use of the air conditioner,
with dedicated magnetothermal / differential switch.
Connection and alimentation cables
- 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:
- Use a multi-pole cable of type H07RN-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.
- Pull lightly on the cable to make sure that the cables have been inserted
and secured properly.
- After connecting the cables, never forget to tighten them to the cable
gland.
