3-2. 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.

It is important that you use extreme care in supporting the indoor unit inside the ceiling.
WARNING
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.
(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. 3-5. (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. 3-6.
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
CAUTION
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
CAUTION
component box in hand.
Do not leave the drain pan of the unit downward for long hours.
CAUTION
If doing so, the insulation material can be crushed.
Crushed insulation can lead to condensation.
