If applying the adhesive, socket will be damaged and
cause water leakage.

Connecting drain pipe
• Connect a hard socket (locally procured) to the hard
socket of the attached supplied flexible hose.
• Connect a drain pipe (locally procured) to the
connected hard socket.
REQUIREMENT
• Connect hard vinyl chloride pipes securely using an
adhesive for vinyl chloride to avoid water leakage.
• It takes some time until the adhesive is dried and
hardened (refer to the manual of the adhesive). Do not
apply stress to the joint with the drain pipe during this
time period.

Drain up
When a down-gradient cannot be secured for the
drainpipe, drain-up piping is possible.
• The height of the drain pipe must be 850 mm or less
from the bottom of the ceiling.
• Take the drain pipe out of the drain pipe joint with the
indoor unit in 300 mm or less, and bend up the pipe
vertically.
• Immediately after the pipe is bent up vertically, lay
the pipe making a down-gradient.
• Set downward grading immediately after raising up
vertically.

Check the draining
In the test run, check that water drain is properly
performed and water does not leak from the connecting
part of the pipes.
Check draining also when installed in heating period.
By using a pitcher or hose, pour water (1500 - 2000 cc)
into the discharge port before installation of the ceiling
panel.
Pour water gradually so that water does not spread on
the motor of the drain pump.
CAUTION
Pour water gently so that it does not spread around
inside the indoor unit, which may cause a malfunction.

Insert the edge of hose into the
drain pan and bend it downward.
CAUTION
Pour water gently so that it does not spread around inside the indoor unit, which may cause a malfunction.
• After the electric work has finished, pour water
during COOL mode operation.
• If the electric work has not yet finished, pull out the float switch connector (CN34: Red) from the electrical control
box, and check draining by plugging the single phase 220 - 240 V power to the terminal blocks R (L) and S (N).
If doing so, the drain pump motor operates.
• Test water drain while checking the operation sound of the drain pump motor.
(If the operation sound changes from continuous sound to intermittent sound, water is normally drained.)
After the check, the drain pump motor runs, connecting the float switch connector.
(In case of check by pulling out the float switch connector, be sure to return the connector to the original position.)
