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. When doing this, also check that no abnormal sounds are heard from the drain pump motor. Check
draining also when installed in heating period.
When the electrical and wiring work has been completed
Pour some water by following the method shown in the following figure. Then, while performing a cooling
operation, check that the water drains from the drain pipe connecting port (transparent) and that no water is
leaking from the drain pipe.
When the electrical and wiring work has not been completed
Disconnect the float switch connector (3P: red) from the connector (CN34: red) on the printed circuit board inside
the electrical control box. (Before doing this, the power must be turned off.)
Connect a 220 - 240 V supply voltage to (L) and (N) on the power supply terminal block. (Do not apply a
220 - 240 V voltage to (A), (B) of the terminal block. Otherwise, the printed circuit board may be damaged.)
Pour the water by following the method shown in the following figure. (Amount of water poured: 1500 cc to
2000 cc)
When the power is turned on, the drain pump automatically starts running. Check whether the water is draining
from the drain pipe connecting port, and check that no water is leaking from the drain pipe.
After checking that the water drains and there are no water leaks, turn off the power, connect the float switch
connector to its original location (CN34) on the printed circuit board, and return the electrical control box to its
original position.

Heat insulating process
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 tightly.
Cover the drain pipe tightly with a heat insulator procured locally so that it overlaps with the attached heat
insulator of the drain connecting section.

CAUTION
Incomplete heat insulation of the supply air flange and sealing may occur dewing resulted in falling of water drop.
Wrap the attached heat insulator tightly from
the surface of the indoor unit.
