CABLE CONNECTION

1. Loosen the mounting screws (2 positions) of the cover of the electric parts box, and then remove the cover.
2. In the Drain Pump Kit, connect the connector (Blue 3P) for drain pump to P.C. board CN68 (Blue 3P) of the
indoor unit, and the connector (Red 3P) for float switch to P.C. board CN34 (Red 3P) of the indoor unit
respectively.
In this time, remove 3P connector (Red 3P)
for short-circuit of CN34 (Red 3P).
3. Using one of two banding bands attached to
the electric parts box, fix the wires.
∗ Use the other banding band to bind the
wires so that they are not caught in the
cover of electric parts box.

TEST RUN

n 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 0.3 galoon (1200cc) 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 208/
230V power to the terminal blocks
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.)
