If the outdoor unit is installed where the heat exchanger of the unit is exposed to direct wind,
provide a windbreak wall.
Intermittent noises may be produced by the indoor unit due to the outdoor fan turning on and off
when using facility settings.

settings are being used. A humidifier might cause dew condensation from the indoor unit outlet
vent.
