4.2 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 the jumper on the outdoor unit PCB. If
the outdoor temperature falls to –20°C or lower, the operation stops. If the outdoor temperature
rises, the operation starts again.
