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 (Figs. 3-1 and 3-2), by attaching them to
the ceiling support structure, or by any other method that ensures
that the unit will be securely and safely suspended.
(2) Follow Fig. 3-2 and Table 3-1 to make the holes in the ceiling.
Table 3-1
Unit: in. (mm)
(3) Determine the pitch of the suspension bolts using the supplied
full-scale installation diagram. The diagram and table (Fig. 3-3
and Table 3-2) show the relationship between the positions of the
suspension fitting, unit, and panel.

3-3. Placing the Unit Inside the Ceiling
(1) When placing the unit inside the ceiling, determine
the pitch of the suspension bolts using the supplied
full-scale installation diagram. (Fig. 3-4)
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
