3-7-2. Suspending the Indoor Unit
Depending on the ceiling type:
1. Check the suspension bolt pitch.
2. Ensure that the ceiling is strong enough to support the weight of the unit.
3. To prevent the unit from dropping, firmly fasten the suspension bolts as shown in the figure below.

(1) When placing the unit inside the ceiling, determine the pitch of the suspension bolts referring to the dimensional data given
previously.Tubing must be laid and connected inside the ceiling when suspending the unit. If the ceiling is already constructed,
lay the tubing into position for connection to the unit before placing the unit inside the ceiling.
(2) Screw in the suspension bolts allowing them to protrude from the ceiling as shown in Fig. 2-145. (Cut the ceiling material,

if necessary.)
(3) Suspend and fix the indoor unit using the 2 hexagonal nuts (field supply) and special washers (supplied with the unit) as
shown in Fig. 2-146.

• Check the unit is placed horizontally.
Make sure the unit is installed level using a level or a vinyl hose filled
with water.
In using a vinyl hose instead of a level, adjust the top surface of the unit to

the surface of the water at both ends of the vinyl hose and make horizontal
adjustment on all 4 corners of the unit.
If the air discharge side of the unit is installed downward, splashing water
or water leak may occur.
Also, the dust may accumulate inside the drain pan caused by draining
residual water.

• When lifting the unit, do not attempt to hold the electrical component box
in hand.
• Do not leave the drain pan of the unit downward for long hours.
If doing so, the insulation material can be crushed.
Crushed insulation can lead to condensation.

It is important that you use extreme care in supporting the indoor unit inside the ceiling.
Ensure that the ceiling is strong enough to support the weight of the unit.
Before suspending the unit, test the strength of each attached suspension bolt.
