3.3 Installation of the Indoor Unit
1. Adjust the positions of the nuts, the size of the gap between the
washer (bottom) and the ceiling should be based on the actual
construction works. See Figure 3.1.
2. Slot the nuts of the lifting bolts in the oblong holes of the lifting lugs.
3. Use a spirit level to verify that the unit body is level. (do not tilt
downwards towards the side where no water is discharged. Best
is to tilt to where water is discharged). See Figure 3.2.

Caution
The indoor unit can be mounted at a height of 2.5 ~ 3.5 metres (2.5 ~ 4 metres for 125 ~ 140 models). As the mounting height of the unit increases,
when the unit is operating in the heating mode, as hot air rises, the heating experience in the vicinity of the ground will become worse.
