Caution 1. If the outdoor unit is installed where the outdoor heat exchanger of the unit is exposed to direct
wind, provide a windbreak wall.
2. Intermittent noises may be produced by the indoor unit due to the outdoor fan turning on and off
when using facility settings.
3. Do not place humidifiers or other items which might raise the humidity in rooms where facility
settings are being used.
A humidifier might cause dew jumping from the indoor unit outlet vent.
