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

12.1.8 Compressor Tank Temperature Rise Protection Control
a. Control start conditions
• For 5 minutes, the compressor continuously operates and outdoor total current is between 0.65A and 1.65A.
• During Cooling and Soft Dry operations:
Indoor suction temperature - indoor piping temperature is below 4℃.
Indoor temperature and outdoor temperature is 30±5℃.
Remote Control setting 16℃ and Hi Fan Speed.
• During Heating operations:
Indoor piping temperature - indoor suction is under 5℃.
Indoor temperature and outdoor temperature is 20 ± 2℃.
Remote control setting 30℃ and Hi Fan Speed.
b. Control contents
• Compressor stops (and restart after 3 minutes)
• If the conditions above happen 2 times within 20 minutes, the unit will:
- Stop operation
- Timer LED blinks and “F91” indicated
12.2 Protection Control for Cooling and Soft Dry Operation
12.2.1 Outdoor Air Temperature Control
• The compressor operating frequency is regulated in accordance to the outdoor air temperature as shown in the
diagram below.
• This control will begin 1 minute after the compressor starts.
• Compressor frequency will adjust base on outdoor air temperature.
