3.15 Facility Setting Jumper (cooling at low outdoor
temperature)
Outline
This function is limited only for facilities (the target of air conditioning is equipment (such as
computer)). Never use it in a residence or office (the space where there is a human).
Detail
You can expand the operation range to –15°C by cutting jumper 8 (J8) on the PCB. If the
outdoor temperature falls to –20°C or lower, the operation will stop. If the outdoor temperature
rises, the operation will start again.
Caution
1. If the outdoor unit is installed where the 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 8 (J8) sets the indoor fan tap to the highest position. Notify the user about
this.
