5. INSTALLATION OF THE INDOOR UNIT



It is easy to attach the optional parts before installing the indoor unit. Refer to also the installation 

manual attached to the optional parts.



For installation, use the attached installation parts and specified parts.

(1)

Attach the upper and lower nuts and the washers for the hanger (3) to the 4 hanging bolts.

(Refer to Fig. 15)

If the attached washer clamp (5) is used, the washer for the hanger (3) can be prevented from falling off. 

(Refer to Fig. 16)

(2)

Installation of indoor unit. 

(Refer to Fig. 17)

Insert the hangers on the air outlet 

 side and hang them tentatively.

Insert the remaining 2 hanging bolts into the hanger and fix the underside washers for the hanger (3) and 
the nuts.

(3)

Check the level of the unit from 2 directions (air outlet 

 and 

). 

(Refer to Fig. 18)

Install the indoor unit leveled
If the unit is inclined and the drain piping side gets high, it may cause malfunction of a float switch and 
results in water leakage.
However, for 2-way air discharge, install the unit inclined 1° downward to the drain piping.

Attach nuts on the upper and lower side of hanger
If there is no upper nut and the lower nut is over-tightened, the hanging plate and the top plate will 
deform and cause abnormal sound.

Do not insert materials other than that specified into the clearance between the hanger and the washer 
for hanger (3).
Unless the washers are properly attached, the hanging bolts may come off from the hanger.

WARNING

The indoor unit must be securely installed on a place that can withstand the mass.

If the strength is insufficient, the unit may fall down and cause injuries.
