„ Connecting drain pipe
• Connect a hard socket (procured locally) to the
hard socket of the attached supplied flexible
hose.
• Connect a drain pipe (procured locally) 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.
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.
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
electric parts box, and check draining by
plugging the single phase 220–240V power to
the terminal blocks ➀ and ➁.
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.)
