INSTALLATION MANUAL Installation of the outdoor unit
ELECTRICAL CONNECTIONS
1. Take the cover away.
2. Connect the cable wires to the terminal board using
the same numbering as in the indoor unit.
3. For the electrical connections, see the wiring diagram
on the back of the cover.
4. Fasten the cables with a cable-clamp.
5. An efficient earth connection must be ensured.
6. Replace the covers.
CONNECTING THE PIPES
Screw the flare nuts to the outdoor unit coupling with
the same tightening procedures described for the indoor
unit.
To avoid leakage, pay attention to the following points:
1. Tighten the flare nuts using two wrenches. Pay atten-
tion not to damage the pipes.
2. If the tightening torque is not sufficient, there will
probably be some leakage. With excessive tightening
torque there will also be some leakage, as the flange
could be damaged.
3. The surest system consists in tightening the connecti-
on by using a fix wrench and a torque wrench: in this
case use the table on page 22.
BLEEDING
Air and humidity left inside the refrigerant circuit can
cause compressor malfunction. After having connected
the indoor and outdoor units, bleed the air and humidity
from the refrigerant circuit by using a vacuum pump.
