3. HOW TO INSTALL THE INDOOR UNIT

4-Way Cassette Type
(U1 Type)

3-1. Suspending the Indoor Unit

This unit uses a drain pump. Use a level gauge to

check that the unit is level.

3-2. Preparation for Suspending

(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.

(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 suspen-

sion fitting, the unit, and the panel.
