Ceiling
material
● The indoor unit includes a drain pump. Be sure to
use a level gauge and verify that the unit is level.
● Before inserting the ceiling material, complete as
much of the drain piping work and refrigerant
tubing work as possible.
(6) The distance between the unit and the opening of
the ceiling and the distance between the bottom
surface of the ceiling and the bottom surface of the
flange of the unit should follow the dimensions given
in Figs. 3-37 and 3-38.
3-10. Installing the Drain Piping
(1) Prepare standard hard PVC pipe (O.D. 1-1/4") for
the drain and use the supplied drain hose and hose
band to prevent water leaks.
The PVC pipe must be purchased separately. The
unit’s transparent drain port allows you to check
drainage. (Fig. 3-39)
● Do not use adhesive at the drain connection port on
the indoor unit.
● Insert the drain pipe until it contacts the socket, as
shown in the figure at right, then secure it tightly with
the hose band.
● Tighten the hose clamps so their locking nuts face
upward. (Fig. 3-39)
● Do not use the supplied drain hose bent at a 90°
angle. (The maximum permissible bend is 45°.)
● Check the drainage at the unit drain port
(transparent).
(2) After checking the drainage, wrap the supplied
packing and drain pipe insulator around the pipe,
then secure it with the supplied clamps. (Fig. 3-40)
Make sure the drain pipe has a downward gradient
(1/100 or more) and that there are no water traps.
