CAUTION

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

ﬂ ange of the unit should follow the dimensions given

in Figs. 3-60 and 3-61.

3-16. 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. 3-62)

CAUTION

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 ﬁ gure at right, then secure it tightly with

the hose band.

Tighten the hose clamps so their locking nuts face

●

upward. (Fig. 3-62)

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. 3-63)

NOTE

Make sure the drain pipe has a downward gradient (1/100

or more) and that there are no water traps.
