Connection procedure, Check the draining

3 DRAIN PIPING WORK

Connection procedure

Connect a socket and a hard vinyl chloride pipe.

•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.

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.

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.

Drain up

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.

•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.)
