Use the specified cables for wiring, and connect them securely with
care to protect electronic parts from external forces.
Improper connections or xing could cause heat generation, re, etc.
Seal the inlet hole for remote control cable with putty.
If dew, water, insect, etc. enters through the hole, it could cause electric shocks, re or
break-down.
If dew or water enters the unit, it may cause screen display anomalies.
When installing the unit at a hospital, telecommunication facility, etc.,
take measures to suppress electric noises.
It could cause malfunction or break-down due to hazardous effects on the inverter,
private power generator, high frequency medical equipment, radio communication
equipment, etc.
The inuences transmitted from the remote control to medical or communication
equipment could disrupt medical activities, video broadcasting or cause noise
interference.

When taking the wiring out from the upper center, open a hole before separating the upper and bottom cases. This will reduce risk of
damaging the PCB and facilitate subsequent work.
When taking the wiring out from the upper left, take care not to damage the PCB and not to leave any chips of cut thin wall inside.

③Connect wires from X and Y terminals of R/C to X and Y terminals of indoor unit. R/C
wires (X, Y) have no polarity. Fix wires such that the wires will run around the terminal
screws on the top case of R/C.
④Install the upper case with care not to pinch wires of R/C.
Cautions for wire connection
Use wires of no larger than 0.5 mm2 for wiring running
through the remote control case. Take care not to pinch
the sheath.
Tighten by hand (0.7 N·m or less) the wire connection.
If the wire is connected using an electric driver, it may
cause failure or deformation.
In case of exposing wiring
(When the wiring is taken out from the “upper center” or
“upper left” of R/C)
①Cut out the thin wall sections on the cases for the size of wire.
② Fix the bottom R/C case on a at surface with two wood
screws.
③
In case of the upper center, pass the wiring behind the
bottom case. (Hatched section)
④
Connect wires from X and Y terminals of R/C to X and Y
terminals of indoor unit. R/C wires (X, Y) have no polarity.
Fix wires such that the wires will run around the terminal
screws on the top case of R/C.
⑤
Install the top case with care not to pinch wires of R/C.
