Installation of outdoor unit
2. Fix the power connection wire and signal control wire with wire clip
(only for cooling and heating unit).
Note:
• After tightening the screw, pull the power cord slightly to check if it is
solid.
• Never cut the power connection wire to extend or shorten the distance.
Step Six: Pipe arrangement
1. The pipes should be placed along
the wall, bent reasonably and
hidden possibly. Min. semi-
diameter of bending the pipe is
10cm.
2. If the outdoor unit is higher than
the wall hole, you must set a
U-shaped curve in the pipe
before pipe goes into the room, in
order to prevent rain from getting
into the room.

hose shouldn't be higher than the
outlet pipe hole of indoor unit.
