SULLAIR Industrial Air Compressor 3012

Warning: High-pressure hazard! Do not remove caps, plugs, and/or other components when compressor is running or pressurized. Stop compressor and relieve all internal pressure before doing so. Failure to comply could result in death or serious injury.

Fluid level in the separator/sump tank

If the fluid level is low, add the necessary amount. If the addition of fluid becomes too frequent, a simple problem has developed which is causing this excessive loss.

See the Section 6.9: Troubleshooting—Introduction on page 61 under EXCESSIVE COMPRESSOR FLUID CONSUMPTION for a probable cause and remedy.

Controller display monitors the correct readings for their particular phase of operation.
