Do not use natural drainage.
Do not install the pipe with an upward gradient from the
connection port. This will cause the drain water to flow
backward and leak when the unit is not operating.
(Fig. 2-9)
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. 2-10)
Provide insulation for any pipes that are run indoors.
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) Slowly pour about 500 cc of water into the drain pan to
check drainage. (Fig. 2-11)

(3) Short the check pin (CHK) on the indoor control board and
operate the drain pump. Check the water flow through the
transparent drain pipe and see if there is any leakage.
(4) When the check of drainage is complete, open the check
pin (CHK) and remount the tube cover.
CAUTION
Be careful since the fan will start when you short the pin on
the indoor control board.
