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.
(2) Follow the diagram to make the holes in the ceiling.
Install the inspection opening on the electrical component box side where maintenance and
inspection of the electrical component box and drain pump are easy.
(3) Determine the pitch of the suspension bolts using the supplied full-scale installation diagram
(printed on container box).
The diagram show the relationship between the positions of the suspension fitting, unit, and
panel.
Use the nut (field supply) and washer (supplied) for upper and lower position of the
suspension lug.
