Facility Setting
(cooling at low outdoor temperature)
This function is limited only for facilities (the target of air conditioning is equipment (such as computer)).
Never use it in a residence or of
fi
ce (the space where there is a human).
Cutting jumper 6 (J6)
on the circuit board will expand the operation range down to 5°F (–15°C). However it will stop if the
outdoor temperature drops below –4°F (–20°C) and start back up once the temperature rises again.
Remove the 3 screws on the side and remove the top plate of the outdoor unit.
1)
Remove the drip proof cover.
2)
Cut the jumper (J6) of the PCB inside.

3) Cut jumper J6.
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 humidi
fi
ers or other items which might raise the humidity in rooms where facility settings are being used.
•
A humidi
fi
er might cause dew jumping from the indoor unit outlet vent.
Cutting jumper 6 (J6) sets the indoor fan tap to the highest position. Notify the user about this.
