● 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.
