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 208V to 230V supply voltage to (L) and (N) on the power supply terminal block.
(Do not apply a 208V to 230V voltage to (U1), (U2), (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: 1.5L to 2L (1/3 to 0.5 gallon))
• 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.

Insulation process
• As shown in the figure, cover the flexible hose and hose band with the attached insulation up to the bottom
of the indoor unit tightly.
• Cover the drain pipe tightly with an insulation procured locally so that it overlaps with the attached insulation
of the drain connecting section.
