Water intake
If it is necessary to increase the height of the
drain pipe, the section directly after the con-
nection port can be raised a maximum of 50
cm. Do not raise it any higher than 50 cm, as
this could result in water leaks. (Fig. 3-107)
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. 3-108)
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 con-
nection to the unit. Fasten the pipe to a wall, frame,
or other support as close to the unit as possible.
(Fig. 3-109)
3-33. 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 about 1,200 cc 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 flow through the transparent drain port and
see if there is any leakage.
(4) When the check of drainage is complete, open the
check pin (CHK) and remount the insulator and
drain cap onto the drain inspection port.
CAUTION
Do not install an air bleed-
er as this may cause water
to spray from the drain
pipe outlet. (Fig. 3-106)
CAUTION
Be careful since the fan will
start when you short the pin
on the indoor control board.
