ACCESSORIES

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 acces-

sory. When the tank pressure drops

to a certain low level the motor will

restart automatically. The low pres-

sure at which the motor automatically

restarts is called "cut-in" pressure.

Cut-Out Pressure: When an air

compressor 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 auto-

matically 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.
