2. Oil Return Line (Scavenge Line) is blocked.
3. Oil Separator is saturated with oil.
4. Wrong type of oil used.
5. Unit is operating at too high a temperature.
6. Oil leak.

4. Change to factory recommended oil.
5. See ‘Section C’.
6. Repair oil leak.
7. Ensure Unit is set to operate at correct
pressures, and there is a minimum of 10 psi
differential. Also the Unit could be oversized for
the tank capacity.
G. Compressor Surges.
1. Restriction in Heat Exchanger or Hoses.
2. Pressure Transducer setting is incorrect or
malfunctioning.
3. Blockage at Unit outlet.
4. If present, the Dryer is freezing up, not
