ENCLOSURE

 - The compressor, electric motor, oil cooler and after cooler are mounted inside the 

enclosure. 
 
Service panels are provided for maintenance access.  Be sure to allow enough space around the unit for 
the panels to be removed.  Any of the enclosure panels may be removed by opening the latch and lifting it 
up slightly. 

 

 

 

Do not operate the compressor with the fan and belt guard removed.  Exposed 
fan and belts may cause injury to personnel. 

 

 

 

The enclosure doors and panels must be closed and latched while the 
compressor is operating.  Failure to close and latch the doors and panels will 
cause high temperature shutdowns.
