3. How to Install the Indoor Unit
3-1. Preparation for Suspending
This unit uses a drain pump. Use a carpenter’s level to
check that the unit is level.
3-2. Suspending the Indoor Unit
(1) Fix the suspension bolts securely in the ceiling using
the method shown in the diagrams, by attaching
them to the ceiling support structure, or by any other
method that ensures that the unit will be securely
and safely suspended. (Fig. 6-1)
(2) Follow the diagram to make the holes in the ceiling.
(3) Determine the pitch of the suspension bolts using
the supplied full-scale installation diagram. The dia-
gram shows the relationship between the positions
of the suspension fitting, unit, and panel. (Fig. 6-2)
3-3. Placing the Unit Inside the Ceiling
(1) Be sure to remove the fan protection (4pcs) for
transportation before hanging up the indoor unit.
(2) When placing the unit inside the ceiling, determine
the pitch of the suspension bolts using the supplied
full-scale installation diagram. (Fig. 6-3)
Tubing and wiring must be laid inside the ceiling
when suspending the unit. If the ceiling is already
constructed, lay the tubing and wiring into position
for connection to the unit before placing the unit
inside the ceiling.
(3) The length of suspension bolts must be appropriate
for a distance between the bottom of the bolt and the
bottom of the unit of more than 19/32" (15 mm) as
shown in the diagram. (Fig. 6-3)
(4) Thread the 3 hexagonal nuts (locally purchased) and
2 supplied washers onto each of the 4 suspension
bolts as shown in the diagram. Use 1 nut and 1
washer for the upper side, and 2 nuts and 1 washer
for the lower side, so that the unit will not fall off the
suspension lugs. (Fig. 6-4)
(5) Adjust so that the distance between the unit and the
ceiling bottom is 1/2" (13 mm) to 23/32" (18 mm).
Tighten the nuts on the upper side and lower side of
the suspension lug. (Fig. 6-4)
