Duty Cycle; Installation - Porter-Cable N003568 Instruction Manual

Become familiar with these terms before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; 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 labo-
ratories and meet the applicable 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 lower level the
motor will restart automatically. The low pressure 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 automatically 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 electricity from electrical panel to outlet.
This air compressor pump is capable of running continuously. However, to
prolong the life of your air compressor, it is recommended that a 50%-75%
average duty cycle be maintained; that is, the air compressor pump should not
run more than 30-45 minutes in any given hour.
Accessories for this unit are available at the store the unit was purchased.
Unpacking
1. Remove unit from carton and discard all packaging.
HOW TO SET UP YOUR UNIT
Location of the Air Compressor
• Locate the air compressor in a clean, dry and well ventilated area.
• The air compressor should be located at least 12" (30.5 cm) away from the
wall or other obstructions that will interfere with the flow of air.
• The air compressor pump and shroud are designed to allow for proper cool-
ing. The ventilation openings on the compressor are necessary to maintain
proper operating temperature. Do not place rags or other containers on or
near these openings.
GROUNDING INSTRUCTIONS
