You can expand the operation range to –10°C by cutting the jumper (J6) on the outdoor unit

PCB. If the outdoor temperature falls to –18°C or lower, the operation stops. If the outdoor

temperature rises, the operation starts again.

Caution 1. If the outdoor unit is installed where the outdoor 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 condensation from the indoor unit outlet vent.

4. Cutting the jumper sets the indoor fan tap to the highest position. (25/35 class,

RXS50K2V1B)

5. Use the indoor unit at the highest level of airflow rate. (RKS50F2V1B, RK(X)S50G2V1B,

RXS50J2V1B)

Caution Replace the PCB if you accidentally cut a wrong jumper.

Jumpers are necessary for electronic circuit. Improper operation may occur if you cut any of

them.
