1. Check temperature difference between intake and discharge air and operating current.

• All amount of refrigerant leaked out. 
• Check refrigeration cycle.

• Refrigerant leakage
• 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 tem-
perature difference is larger.

2. Check temperature and pressure of refrigeration cycle.

Notice:
1. The suction pressure is usually 4.5~6.0 kg/cm

2

G at normal condition.

2. The temperature can be measured by attaching the thermometer to the low pressure tubing and wrap it with

putty.
