3.11.2 Installing

3.11.2.1. Anti-falling;

To prevent the indoor unit from falling, you must:

a. Pay full attention to the unit because its long outer shape makes it easy to fall;

b. Firmly fix the unit to the wall or in the ground to avoid accidental falling.

3.11.2.2. Dismounting the lower front panel

Please take off the air-inlet grid before connecting the pipes/wires.

Pull down the two knobs on the grille, take off the two screws, then the air-inlet grille goes free.

3.11.2.3. Take the Pipe Clip off before connecting the pipes and wiring; fit it when these finished.

Use accessories to connect the pipes/wires on both sides and back side.
