Cycle Troubleshooting Guide
Trouble analysis
1. Check temperature difference between intake and discharge air and operating current.
Temp. Difference
Temp. difference
: approx. 0°C
Current
: less than 80% of
rated current
Temp. difference
: approx. 8°C
Current
: less than 80% of
rated current
Temp. difference
: less than 8°C
Current
: over the reated
current
Temp. difference
: over 8°C
Operating Current
• All amount of refrigerant leaked
out. Check refrigeration cycle.
• Refrigerant leakege
Clog of refrigeration cycle
Defective compressor

• Excessive amount of refrigerant
• Normal
Notice :
Temperature difference between intake and discharge air depends on room air humidity. When the room air
humidity is relativery higher, temperature difference is smaller. When the room air humidity is relatively lower
temperature difference is larger.

2. Check temperature and pressure of refrigeration cycle.
Notice :
1. The suction pressure is usually 4.5~6.0 kg/cm
