16.1.5 Low Pressure Prevention Control (Gas Leakage Detection)
 Control start conditions
o For 5 minutes, the compressor continuously operates and outdoor total current is between 0.36A and 0.54A
(Z25/35/42/50/71VKE), between 0.29A and 0.44A (Z20VKE).
o During Cooling and Soft Dry operations:
Indoor suction temperature - indoor piping temperature is below 4°C.
o During Heating operations :
Indoor piping temperature - indoor suction is under 5°C.
 Control contents
o Compressor stops (and restart after 3 minutes).
o If the conditions above happen 2 times within 20 minutes, the unit will:
 Stop operation
 Timer LED blinks and “F91” indicated.
16.1.6 Low Frequency Protection Control 1
 When the compressor operate at frequency lower than 24 Hz continued for 240 minutes, the operation frequency
will be changed to 23 Hz for 2 minutes.
16.1.7 Low Frequency Protection Control 2
 When all the below conditions comply, the compressor frequency will change to lower frequency.
Temperature, T, for: Cooling/Soft Dry Heating
Indoor intake air (°C) T < 14 or T ≥ 30 T < 14 or T ≥ 28
Outdoor air (°C) T < 13 or T ≥ 38 T < 4 or T ≥ 24
Indoor heat exchanger (°C) T < 30 T ≥ 0
