● Do not install the remote control at following places.
①It could cause break-down or deformation of remote control.
・Where it is exposed to direct sunlight
・Where the ambient temperature becomes 0 °C or below, or 40 °C or above
・Where the surface is not flat
・Where the strength of installation area is insufficient
②Moisture may be attached to internal parts of the remote control, resulting in a display failure.
・Place with high humidity where condensation occurs on the remote control
・Where the remote control gets wet
③Accurate room temperature may not be detected using the temperature sensor of the remote
control.
・Where the average room temperature cannot be detected
・Place near the equipment to generate heat
・Place affected by outside air in opening/closing the door
・Place exposed to direct sunlight or wind from air-conditioner
・Where the difference between wall and room temperature is large
④When you are using the automatic grille up and down panel in the IU, you may not be able to
confirm the up and down motion.
・Where the IU cannot be visually confirmed
● 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 influences transmitted from the remote control to medical or communication equipment could
disrupt medical activities, video broadcasting or cause noise interference.
R/C cable:0.3mm2x 2 cores
When the cable length is longer than 100 m,
the max size for wires used in the R/C case
is 0.5 mm2. Connect them to wires of larger
size near the outside of R/C. When wires are
connected, take measures to prevent water,
etc. from entering inside.
Adapted RoHS directive
(b) Wired remote control (Option parts)
Interface kit (SC-BIKN-E, SC-BIKN2-E) is required to use the wired remote control.
When RC-EX3A is connected, please use SC-BIKN2-E by all means.

1) If the prolongation is over 100m, change to the s ize below.
But, wiring in the remote control case should be under 0.5mm2. Change the wire size outside of
the case according to wire connecting. Waterproof treatment is necessary at the wire connecting
section. Be careful about contact failure.
