leaked out.
Check refrigeration cycle.
Refrigerant leak or
Clog of refrigeration cycle
(restriction)
Defective compressor
Excessive amount of
refrigerant or restricted con-
denser coil airflow.
Normal
Notice:
Temperature difference between intake and discharge air depends on room air humidity. When the room air humidity is
relatively 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 70-75 PSIG at normal condition.
2. The temperature can be measure by attaching the thermometer to the low pressure tubing and wrap it with putty.
