Step five: connect the outdoor electrical cable

1. Remove the wire clip. Connect the power cable and the signal control cable (only for cooling and

heating units) to the wiring terminal according to colour. Secure them with the screws.

2. Secure the power cable and the signal control cable with the clip (only for cooling and heating

units).

N.B.: • Once you have tightened the screw, pull on the power cable gently to check it is secure.

• Never cut the power cable to extend or reduce the distance.

Step six: tidy up the pipes

1. The pipes should be routed along the wall,

bent only as much as is necessary and, if

possible, hidden from view. Minimum pipe

bending radius: 10 cm.

2. If the outdoor unit is higher than the hole in

the wall, you must create a U-bend in the pipe

before it enters the room to prevent rain from

getting into the room.
