Unit suspension procedures
• Adjust the length of the bolt's protrusion from the ceiling surface be-
forehand.
• Check the pitch of the suspension bolt (E). (308 mm × 1051 mm)
1) Install special washer (3) and their nuts (F) onto the suspension bolt
(E) in advance.
* Do this in the following order (from the top): nut (F), special washer
with cushion (3), special washer (3), nut (F), nut (G).
* Position special washer, with cushion (3) with the insulated surface
2) Lift the unit into place, aligned properly with suspension bolt (E).
Pass the bracket between special washer, with cushion (3) and
special washer (3), which are already in place, and secure it. Do the
same in all four places.
* Make sure the suspension bolt (E) extends 20 mm or more from
the surface of the ceiling. Otherwise you will not be able to install
the grille (optional).

ing surface, water may condense, or the panel may not open/
close.
3) If the long opening in the bracket and opening in the ceiling do not
align, adjust them until they do.
4) Check that the four corners are all level, using a spirit level or clear
plastic tubing with water in it.
* Water may drip from the unit if it is not installed horizontally.
5) Tighten all the nuts.
2-2. HOLE DRILLING
1) Determine the wall hole position.
2) Drill a dia. 75 mm hole. The outdoor side should be 5 to 7 mm lower
than the indoor side.
3) Insert wall hole sleeve (J).

2-3. DRAIN PIPING

• Use drain pipe (B) for drain piping. Be sure to connect the piping
joints using adhesive of polyvinyl chloride family to prevent leakage.
• Before drain piping work, remove the pipe cover, hose band, pipe
band, and spacer (cushion). Dispose of the spacer (cushion), as it will
not be needed.
• Drain hose (2) is 540 mm long, so that drain piping exit can be moved
up. Cut drain hose (2) into appropriate length before connecting.
