If it is necessary to
increase the height of the
drain pipe, the section
directly after the connec-
tion port can be raised a
maximum of 64 cm. Do
not raise it any higher
than 64 cm, as this could
result in water leaks.
(Fig. 3-56)
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. 3-57)
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 possi-
ble. (Fig. 3-58)
Provide insulation for any
pipes that are run
indoors.
3-17. 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 1,200 cc of water into the drain
pan to check drainage. (Fig. 3-59)
(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.
