Placing the Unit Inside the Ceiling
This unit is equipped with the drain pump. Check a tape
measure or carpenter’s level.
Before installing the panel for cassette, complete the
work of drain pipe and refrigerant tube installation.
(1) When placing the unit inside the ceiling, determine the
pitch of the suspension bolts using the supplied full-scale
installation diagram.
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.
(2) 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 18 mm.
(3) Thread the 3 hexagonal nuts and 2 washers onto each
of the 4 suspension bolts. 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.

(4) Adjust so that the distance between the unit and the
ceiling bottom is 12 to 17 mm. Tighten the nuts on the
upper side and lower side of the suspension lug.
(5) Remove the protective polyethylene used to protect the
fan parts during transport.
(6) Check with a tape measure or carpenter’s level.

3. HOW TO INSTALL THE INDOOR UNIT
●
Preparation for Suspending
This unit uses a drain pump. Use a carpenter’s level to check
that the unit is level.
●
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.
(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.
* The overlapping portion between the ceiling and panel for cassette should be kept over 20 mm.
