Electrical connections
The terminal blocks on the units must be accessed to car-
ry out the electrical connections.
See the pictures at the side.
To ensure correct size of the wires for the electrical
connection and for connecting the units together,
see the technical data table.
For the electrical connections, see the circuit dia-
gram inside the access flap and refer to the informa-
tion given in this manual.
The cable connecting the outdoor and indoor units
must be suitable for outdoor use.
The plug must be accessible also after the applian-
ce has been installed so that it can be pulled out if
necessary.
Installation of an omnipolar thermomagnetic line-
disconnecting switch to CEI-EN standards (with con-
tact separation of at least 3 mm) near the appliance
is compulsory.
An efficient earth connection must be ensured.
If the power cable is damaged, it must be replaced by
an authorised Service Centre.
Under no circumstances should gas or water pipes
be used for earthing the appliance.
Upon completion of connections, secure the cables
with cable glands and replace the terminal block
covers.
Failure to comply with these instructions and acci-
dent-prevention regulations relieves the manufactu-
rer from all liability.
