After pouring some water, reassemble the rubber
cap on the connection part of a flexible hose of
the indoor unit and firmly tighten it with a band to
prevent leakage.
c
Check the leak test at the part where the adhesive
for the flexible hose and the drain pipe is used.
CAUTION
࡛
The leak test must be performed for at least 24 hours.
2
Check the condensed water drainage:

pan as shown in the picture.
b
When the electric cable connection is completed
࡛
Turn on the indoor unit and outdoor unit.
࡛
Operate in the Cool mode.
CAUTION
࡛
Only in the Cool mode, you can check the correct
operation of the drain pump.
When the electric cable connection has not been
completed
࡛
Remove the control box cover of the indoor unit.
࡛
Connect the power supply to the L and N terminals.
࡛
Reassemble the control box cover and turn on the
indoor unit.
CAUTION
࡛
When the float switch is not detected due to
insufficient water on the drain pan, the drain
pump will not work.
࡛
If the power supply is directly connected to the L
and N terminals, communication error message
might appear.
࡛
After completing the drainage check, turn the unit
off and disconnect the power supply.
࡛
Reassemble the control box cover.
c
Check whether the drain pump works correctly.
d
Check whether the drainage is performing
correctly at the end of the drain pipe.
e
Check for leakage at the drain pipe and drain pipe
connection part.
f
When leakage occurs, check whether the indoor
unit is level and check the drain hose connection
part, drainpipe connection part and drain pump
connection.
g
When the drainage check is completed and
the condensed water remains on the drain pan,
remove the water.
Step 12 Connecting the power and
communication cables
Power and communication cable connection
࡛
Before wiring work, you must turn off all power source.
࡛
Connect the power and communication cable among
the units within maximum length to set the voltage
drop under 10%.
࡛
The auxiliary circuit breaker (ELCB, MCCB, ELB) should
be considered more capacity if many indoor units are
connected from one breaker.
࡛
Connect F3, F4(for communication) to the
communication cable of the wired remote control.
࡛
Tighten the electric wires with a proper tool within the
torque limit to connect and fix them firmly, and then
organize the wires to prevent outside pressure being
exerted on the covers and other parts. Failure to do so
may result in overheating, electric shock, and fire.
