8.2.1.6. Low Pressure Prevention Control (Gas Leakage Detection)
1. When the conditions listed in below table occur, the compressor stops and restarts after three minutes.
2. If this phenomenon is continuously occurring for twice within 20 minutes, all indoor and outdoor relays will be cut off.
3. This control is not applicable for deice operation.

8.2.1.8. Low Frequency Protection Control 1
When the compressor operate at frequency lower than 26 Hz (XE9CK), 28 Hz (XE12CK) for 240 minutes, the operation frequency
will be increased to 26 Hz (XE9CK), 28 Hz (XE12CK) for two minutes.
