Cutting jumper 6 (J6) on the circuit board will expand the operation range down to 14°F (–10°C). However it will stop if
the outdoor temperature drops below –0.4°F (–18°C) and start back up once the temperature rises again.
1) Remove the 3 screws on the side and remove the top plate of the outdoor unit.
2) Remove the drip proof cover.

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 6 (J6) sets the indoor fan tap to the highest position. Notify the user about this.
