Air Treatment Recommendations
This compressor configuration does not include an integrated refrigerated air dryer. Compressed air naturally contains moisture, oil aerosols, and particulate contamination that may need to be removed before the air reaches downstream equipment.
Depending on the application, the compressed-air system may also require:
- Refrigerated compressed-air dryer
- Moisture separator
- Automatic receiver-tank drain
- General-purpose particulate filter
- High-efficiency coalescing filter
- Activated-carbon filter
- Pressure regulator
- Oil-water separator
- Point-of-use filtration
Paint spraying, CNC machinery, instrumentation, automation equipment, and moisture-sensitive production processes normally require additional drying and filtration.
The dryer and filters should be sized according to compressor airflow, operating pressure, inlet temperature, ambient conditions, required air quality, and acceptable system pressure drop.
Installation Considerations
The compressor should be installed indoors on a level, structurally adequate surface with sufficient space for ventilation, inspection, and routine maintenance.
Before installation:
- Confirm that the facility has 208, 230, or 460-volt three-phase electrical service.
- Verify that total compressed-air demand is within the compressor’s 54.9 ACFM capacity.
- Confirm that piping, filters, dryers, and downstream equipment are rated for the operating pressure.
- Provide adequate ventilation around the compressor.
- Prevent heated cooling air from recirculating into the compressor intake.
- Install the required electrical disconnect and overcurrent protection.
- Use properly sized compressed-air piping.
- Install a flexible connection between the compressor and rigid piping.
- Verify that the receiver-tank condensate drain is installed and operating correctly.
- Route oily condensate to an approved oil-water separator or disposal system.
- Maintain the manufacturer’s recommended service clearances.
- Verify proper motor rotation during startup.
- Complete Chicago Pneumatic’s startup and warranty-registration requirements.

Basic Troubleshooting
Compressor Cannot Maintain Pressure
Check for compressed-air leaks, an open condensate drain, a restricted intake filter, incorrect pressure settings, or downstream equipment consuming more than the available 54.9 ACFM.
Compressor Runs Hot or Shuts Down
Inspect room ventilation, ambient temperature, cooler cleanliness, lubricant level, intake restrictions, cooling-fan operation, and the possibility of heated cooling air recirculating into the compressor intake.
Compressor Loads and Unloads Frequently
Check for compressed-air leaks, rapidly changing air demand, incorrect pressure settings, an open condensate drain, or demand that is too low or inconsistent for the compressor.
Compressor Does Not Start
Check the electrical disconnect, incoming voltage, fuses, circuit protection, emergency-stop control, controller settings, and any active fault or shutdown condition.
Compressor Rotation Is Incorrect
Three-phase electrical connections may need to be corrected to achieve proper motor rotation. Disconnect power and have a qualified electrician correct the phase rotation before operating the compressor.
Excessive Moisture Downstream
Check the receiver-tank drain and condensate-removal equipment. Install a properly sized refrigerated dryer, moisture separator, and filtration system when dry compressed air is required.
Excessive Pressure Drop
Inspect compressed-air filters, piping size, isolation valves, regulators, and filter elements for restrictions or contamination.
Controller Displays a Warning or Fault
Record the warning or fault information and consult the operating manual. Do not repeatedly reset protective shutdowns without identifying and correcting the underlying cause.
Electrical repairs, internal pressure-system repairs, controller repairs, and major compressor service should be completed by qualified service personnel.
