„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.

Installation Manual

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.

„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 33.5" (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 11.8" (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 (0.4 - 0.5 gal (1500 - 2000 cc)) into the discharge port before installation of the ceiling panel.

Water (0.4 - 0.5 gal (1500 - 2000 cc))

• 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 208/230 V power to the terminal blocks L1 and

L2.

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.)
