2. Installing the Drain Hose
CAUTION
Do not apply force to the drain port when connecting the
drain hose. Install and fix it near the indoor unit as close as
possible.
Do not use adhesive when connecting the drain port pipe
and the drain hose.
(1) How to Install the Drain Hose
1) First insert the supplied hose band into the drain port pipe.
Then make sure the head of the screw is facing toward a
technical engineer when placing the screw of the hose band
at an upward angle.
2) Insert the soft PVC socket of the supplied drain hose to the
drain port pipe. Do not use adhesive when connecting the
drain hose to the drain port pipe.
Insert it until the tip of the drain hose contacts the circular
projection rib of the drain port pipe.
3) Move the hose band so that the center position of the hose
band can be placed approx. 1-3/16” (30 mm) away from the
external plate of the indoor unit. (Fig. 1-129)
4) Screw the drain hose tightly facing the screw of the hose
band upward. (Torque: 22 - 30 lbf·inch (2.5 N·m - 3.4 N·m))
(If the screw is tightened beneath the drain hose, the
troubles will be generated.) Pay attention not to make hose
band overlap the circular projection rib and the sealed
circulation projection of the drain port hose.
5) Move the drain socket showing in the direction of the arrow
toward the drain hose and connect with the adhesive
(approx. 0.07 oz (2 )).
6) Then connect the hard PVC pipe (field supply) on the
opposite side of the drain socket.
Apply the adhesive (approx. 0.07 oz (2 )) between the two
parts.
After connection, remove sticky adhesive left over the
surface.

6-39. Checking the Drainage
Be careful because the fan will start when you short the pin on the indoor control board.
After wiring (refer to “1-12. ELECTRICAL 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 (L1, L2 terminals) inside the electrical component box.
(2) Slowly pour about 0.3 gal (1,200 cc) of water into the drain pan to check drainage. (Fig. 1-130)
(3) Short the check pin (CHK) on the indoor control board and operate the drain pump. Check the water flow through the transparent

(4) When the check of drainage is complete, open the check pin (CHK) and remount the tube cover.
