• Remove the control box cover of the indoor unit.
• Connect the power supply (220 to 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.

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.
– Do not disconnect the power plug from the wall
outlet with power on.
– It is recommended to locate the outlet in a high
position. Place the cords so that they are not
tangled.
• Always remember to connect the air conditioner to
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.
