Facility Setting
(cooling at low outdoor temperature)
WARNING
• Make sure to turn the power OFF before removing the service lid.
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.
• Activating the facility setting sets the indoor fan tap to the highest position.
Notify the user about this.
This function is designed for facilities such as equipment or computer rooms. It is never to be used in a
residence or office where people occupy the space.
1) Turning on SW5-3 on the PCB will extend the operation range to 14°F (–10°C).
Installing an air direction adjustment grille (sold separately) will further extend the operation range to –4°F (–20°C). In these
cases, the unit will stop operating if the outdoor temperature falls below –4°F (–20°C), restarting once the temperature rises
above this level.
