The unit with Scroll Compressor can only rotate in one direction. For this reason, a protective device (phase protector) is fitted

to prevent incorrect wiring of the electrical phases. When the three phases are not connected correctly, the phase protector

operates, and the unit will not start. This device is located in the control box of the outdoor unit.

The following table shows the LED indicator light for phase protector under normal operation and fault conditions.

Notes: 1. “+” indicates additional functions for PP01 phase protector.

2. When R phase missing, no LED or buzzer will indicate the error, but relay 71 and relay 81 will cut off.
