● Do not install the remote control at following places.
1) It 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
2) Moisture 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
3)
Accurate 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
4) When 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:0.3mm2 x 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.

1) If the prolongation is over 100m, change to the size 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.

※At the connection with the duct type indoor unit. The specifications shown in the above table are for units without heaters. For units with heaters, refer
to the installation instructions or the construction instructions of the indoor unit.
Switchgear of circuit breaker capacity which is calculated from MAX. over current should be chosen along the regulations in each country. The cable specifications are based on the assumption that a metal or plastic conduit is used with no
more than three cables contained in a conduit and a voltage drop is 2%. For an installation falling
outside of these conditions, please follow the internal cabling regulations. Adapt it to the regulation in effect in each country.
