GLOSSARY
SCFM or CFM: Standard Cubic Feet per Minute; a unit of
measurement of air delivery.
PSIG or PSI: Pounds per square inch gauge.
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 approximately 100 PSI
the motor will restart automatically. The low pressure at
DUTY CYCLE
which the motor automatically re-starts is called "cut-in
pressure."
CUT-OUT PRESSURE: When you turn on your air compressor and it begins to run, air pressure in the air tank
begins to build. It builds to approximately 125 PSI before the
motor automatically shuts off .The high pressure at which
the motor shuts off is called "cut-out pressure."
All DeVilbiss Air Power manufactured air compressors
should be operated on not more than a 50% duty cycle.
This means an air compressor that pumps air more than
STORAGE
When you have finished using the air compressor:
1. Set the "ON/OFF" switch to "OFF" and unplug the
cord.
2. Review the "Operating Procedures" section (page 8).
Be sure to drain the water from the air tank.
50% of one hour is considered misuse, because the air
compressor is undersized for the required air demand.
Maximum compressor pumping time per hour is 30 minutes.
3. Protect the electrical cord and air hose from damage by
winding them loosely around the air compressor.
4. Store the air compressor in a clean and dry location.
5 - ENG
DESCRIPTION OF OPERATION
Air Compressor Pump: To compress air, the piston
moves up and down in the cylinder. On the downstroke, air
is drawn in through the intake valves. The exhaust valves
remain closed. On the upstroke of the piston, air is
compressed. The intake valves close and compressed air
is forced out through the exhaust valves, through the outlet
tube, through the check valve and into the air tank. Working
air is not available until the compressor has raised the tank
pressure above that required at the air outlet.
Check Valve: When the air compressor is operating, the
check valve is “open”, allowing compressed air to enter the
air tank. When the air compressor reaches “cut-out”
pressure, the check valve “closes”, allowing air pressure to
remain inside the air tank.
Pressure Switch: The pressure switch automatically
starts the motor when the tank pressure drops below the
factory set “cut-in” pressure. It stops the motor when the
air tank pressure reaches the factory set “cut-out” pressure.
Regulator: The air pressure coming from the air tank is
controlled by the regulator. Turn the regulator knob clockwise to increase pressure and counterclockwise to
decrease pressure. To avoid minor readjustment after
making a change in pressure setting, always approach the
desired pressure from a lower pressure. When reducing
from a higher to a lower setting, first reduce to pressure less
than that desired, then bring it up to the desired pressure.
Depending on the air requirements of each particular
accessory, the outlet regulated air pressure may have to be
adjusted while operating the accessory.
Outlet Pressure Gauge: The outlet pressure gauge
indicates the air pressure available at the outlet side of the
regulator. This pressure is controlled by the regulator and
is always less or equal to the tank pressure. See “Operating Procedures”.
Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the tank.
Cooling System: This compressor contains an advanced
design cooling system. At the heart of this cooling system
is an engineered fan. It is perfectly normal for this fan to blow
air through the vent holes in large amounts. You know that
the cooling system is working when air is being expelled.
Air Intake Filter: This unit requires no air filter due to the
unique design of the air intake system.
Drain Valve: The drain valve is located at the base of the
air tank and is used to drain condensation at the end of each
use.
On/Auto-Off Switch: Turn this switch ON to provide
automatic power to the pressure switch and OFF to remove
power at the end of each use.
INSTALLATION AND BREAK-IN PROCEDURES
Location of the Air Compressor
Your compressor comes to you completely assembled
and ready for use. Operate the air compressor in a dry,
clean, cool and well ventilated area. The air compressor
pump and case are designed to allow for proper cooling.
Clean or blow off dust or dirt that collects on the air
compressor. A clean air compressor runs cooler and
provides longer service. The ventilation openings on your
air compressor are necessary to maintain proper operating
temperature. Do not place rags or other containers on or
near these openings.
Voltage and Circuit Protection
See front cover.
6 - ENG
Extension Cords
Use extra air hose instead of an extension cord to avoid
voltage drop and power loss to the motor.
If an extension cord must be used, be sure it is:
• a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that will accept the
plug on the compressor.
• in good condition.
• no longer than 50 feet.
• 14 gauge (AWG) or larger. (Wire size increases as
gauge number decreases.) 12 AWG, 10 AWG and
8 AWG may also be used. DO NOT USE 16 OR 18
AWG.
INSTALLATION AND BREAK-IN
PROCEDURES
GROUNDING INSTRUCTIONS
RISK OF ELECTRICAL SHOCK! IN THE EVENT
OF A SHORT CIRCUIT, GROUNDING REDUCES
THE RISK OF SHOCK BY PROVIDING AN
ESCAPE WIRE FOR THE ELECTRIC CURRENT.
THIS AIR COMPRESSOR MUST BE PROPERLY
GROUNDED.
The air compressor is equipped with a cord having a
grounded wire with an appropriate grounding plug. The
plug must be used with an outlet that has been installed
and grounded in accordance with all local codes and
ordinances. The outlet must have the same configuration
as the plug. See illustration. DO NOT USE AN ADAPT-
ER.
Inspect the plug and cord before each use. Do not use if
there are signs of damage.
IMPROPER GROUNDING CAN RESULT IN
ELECTRICAL SHOCK.
Do not modify the plug that has been provided. If it does
not fit the available outlet, the correct outlet should be
installed by a qualified electrician.
If repairing or replacing cord or plug, the grounding wire
must be kept separate from the current-carrying wires.
Never connect the grounding wire to a flat blade plug
terminal. The grounding wire has insulation with an outer
surface that is green - with or without yellow stripes.
If these grounding instructions are not completely understood, or if in doubt as to whether the compressor is
properly grounded, have the installation checked by a
qualified electrician.
Additional Regulators and
Controls
Since the air tank pressure is usually greater than that
which is needed, a regulator is employed to control the
air pressure ahead of any individual air driven device.
Separate air transformers which combine the function of
air regulation, moisture and dirt removal should be used
where applicable.
Break-in Procedures
Serious damage may result if the
following break-in instructions are
not closely followed.
This procedure is required:
1. Before the air compressor is put into service.
2. When the check valve is replaced.
a. Set the pressure switch lever to the "OFF"
position.
b. Plug the power cord into the correct branch
circuit receptacle.
c. Turn the regulator clockwise, opening it fully, to
prevent air pressure build-up in the tank.
d. Move the pressure switch lever to "ON/AUTO".
The compressor will start.
e. Run the compressor for 15 minutes. Make sure
the regulator is open and there is no tank
pressure build-up.
f. After 15 minutes, close the regulator by turning
knob counterclockwise. The air receiver will fill
to cut-out pressure and the motor will stop. The
compressor is now ready for use.
7 - ENG
OPERATING PROCEDURES
1. Before attaching air hose or accessories, make sure
the OFF/AUTO lever is set to “OFF” and the air
regulator or shut-off valve is closed.
2. Attach hose and accessories.
TOO MUCH AIR PRESSURE CAUSES A
HAZARDOUS RISK OF BURSTING. CHECK
THE MANUFACTURER'S MAXIMUM PRESSURE RATING FOR AIR TOOLS AND
ACCESSORIES. THE REGULATOR OUTLET
PRESSURE MUST NEVER EXCEED THE
MAXIMUM PRESSURE RATING.
3. Turn the OFF/AUTO lever to “AUTO” and allow tank
pressure to build. Motor will stop when tank pressure
reaches “cut-out” pressure.
4. Open the regulator by turning it clockwise. Adjust the
regulator to the correct pressure setting. Your compressor is ready for use.
5. Always operate the air compressor in well-ventilated
areas; free of gasoline or other solvent vapors. Do not
operate the compressor near the spray area.
When you are finished:
6. Set the “OFF/AUTO” lever to “OFF”.
7. Turn the regulator counterclockwise and set the
outlet pressure to zero.
8. Remove the air tool or accessory.
9. Open the regulator and allow the air to slowly bleed
from the tank. Close the regulator when tank
pressure is approximately 20 psi.
10. Drain water from air tank.
WATER WILL CONDENSE IN THE AIR
TANK. IF NOT DRAINED, WATER WILL
CORRODE AND WEAKEN THE AIR TANK
CAUSING A RISK OF AIR TANK RUPTURE.
NOTE
If drain cock valve is plugged, release all air
pressure. The valve can then be removed,
cleaned, then reinstalled.
11. After the water has been drained, close the drain
cock or drain valve. The air compressor can now be
stored.
