CAUTION
• 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.
• 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 condensation from the indoor unit outlet vent.
• Cutting jumper 4 (J4) sets the indoor fan tap to the highest position. Notify the user about this.
