3-22. Installing the Drain Piping

(1) Prepare standard hard PVC pipe (O.D. 1-1/4") for the drain

and use the supplied hose band to prevent water leaks.

The PVC pipe must be purchased separately.

The transparent drain part on the unit allows you to check

drainage. (Fig. 3-91)

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.

Do not use the supplied drain hose bent at a 90° angle.

●

(The maximum permissible bend is 45°.)

Tighten the hose clamps so their locking nuts face upward.

●

(Fig. 3-91)

(2) After connecting the drain piping securely, wrap the supplied

packing and drain pipe insulator around the pipe, then secure it

with the supplied vinyl clamps. (Fig. 3-92)

NOTE

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

and that there are no water traps.

CAUTION

Do not install an air bleeder as this may

●

cause water to spray from the drain pipe

outlet. (Fig. 3-93)

If it is necessary to increase the height of the drain pipe, the

●

section directly after the connection port can be raised a

maximum of 19-11/16”. Do not raise it any higher than

19-11/16”, as this could result in water leaks. (Fig. 3-94)

Do not install the pipe with an upward gradient from the

●

connection port. This will cause the drain water to ﬂ ow backward

and leak when the unit is not operating. (Fig. 3-95)

Do not apply force to the piping on the unit side when connecting

●

the drain pipe. The pipe should not be allowed to hang

unsupported from its connection to the unit. Fasten the pipe to a

wall, frame, or other support as close to the unit as possible.

(Fig. 3-96)

Refer to “■ SUPPLEMENT ON DRAIN PIPING”.

3-23. Checking the Drainage

After wiring and drain piping are completed, use the following

procedure to check that the water will drain smoothly. For this,

prepare a bucket and wiping cloth to catch and wipe up spilled water.

(1) Connect power to the power terminal board (R, S terminals)

inside the electrical component box.

(2) Remove the tube cover and through the opening, slowly pour

approx. 0.3 gal of water into the drain pan to check drainage.

(3) Short the check pin (CHK) on the indoor control board and

operate the drain pump. Check the water ﬂ ow through the

transparent drain port and see if there is any leakage.
