GLOSSARY

Become familiar with these terms before operating the unit.

CFM: Cubic feet per minute.

SCFM: Standard cubic feet per min- ute; a unit of measure of air delivery. PSIG: Pounds per square inch gauge; a unit of measure of pressure.

Code Certification: Products that bear one or more of the following marks: UL, CUL, ETL, CETL, have been evaluated by OSHA certified independent safety laboratories and meet the applicable Underwriters Laboratories Standards for Safety. Cut-In Pressure: While the motor is Off, air tank pressure drops as you

continue to use your accessory. When the tank pressure drops to a certain low level the motor will restart auto- matically. The low pressure at which the motor automatically restarts is called "cut-in" pressure.

Cut-Out Pressure: When an air com- pressor is turned on and begins to run, air pressure in the air tank begins to build. It builds to a certain high pressure before the motor automati- cally shuts Off, protecting your air tank from pressure higher than its capacity. The high pressure at which the motor shuts Off is called "cut-out" pressure.

Branch Circuit: Circuit carrying elec- tricity from electrical panel to outlet.

average duty cycle be maintained; that is, the air compressor pump should not run more than 30-45 minutes in any given hour.
