Check the condensed water drainage:
a
Pour about 2 liters of water into the indoor unit
drain 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 (220~240V, 50 Hz) 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

Step 12 Connecting the power and
communication cables
CAUTION
•
Always remember to connect the refrigerant pipes
before performing the electric connections.
When disconnecting the system, always disconnect the
electric cables before disconnecting the refrigerant
pipes.

For the product that uses the R-32 refrigerant, be
cautious not to generate a spark by keeping the
following requirements:
–
Do not remove the fuses with power on.

the grounding system before performing the electric
connections. Use a crimp ring terminal at the end of
each wire.
The indoor unit is powered through the outdoor unit by means
of a H07 RN-F connection cable (or a more power model), with
insulation in synthetic rubber and a jacket in polychloroprene
(neoprene), in accordance with the requirements specified in
the standard EN 60335-2-40.
1
Remove the screw on the electrical component box and
remove the cover plate.
2
Route the connection cord through the side of the indoor
