• Using adhesive agent for vinyl chloride pipe, connect

the drain pipes certainly so that water does not leak.

• It takes approx. 10 hours to dry and harden the

adhesive agent.  During this period, do not apply
force to the connecting part with the drain pipe.

• As shown in the figure, cover the flexible hose and

hose band with the attached heat insulator up to the
bottom of the indoor unit without gap.

When a downward grading cannot be secured on the
drain pipe, drain-up up to 640mm is possible.

Set downward grading immediately after raising up
vertically.

In the test run, check that water drain is properly
performed and water does not leak from the
connecting part of the pipes.

Be sure to check draining also when installed in
heating period.

Using a pitcher or hose, pour water (1500 to 2000cc)
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.

• 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 electric
parts box, and check draining by plugging the single
phase 220/230/240V power to the terminal blocks 1
and 2.
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.)
