CAUTION
● If it is necessary to
increase the height of
the drain pipe, the sec-
tion directly after the
connection 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 back-
ward 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 sup-
port as close to the unit
as possible. (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.
