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.)
Pump
Insert the edge of hose into the
drain pan and bend it downward.

Perform heat insulating
• 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.
• Cover the drain pipe seamlessly with a heat insulator to be procured locally so that it overlaps with the attached
heat insulator of the drain connecting section.
* Direct the slits and seams of the heat insulator upward to avoid water leakage.
Wrap the attached heat insulator seamlessly from
the surface of the indoor unit.
