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.
4. Cutting jumper sets the indoor fan tap to the highest position. (20/25/35/42 class)
5. Use the indoor unit at the highest level of airflow rate. (50 class)
