GLOSSARY
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.
ASME: American Society of Mechanical Engineers; made,
tested, inspected and registered to meet the standards of the
ASME.
California Code: Unit may comply with California Code
462 (L) (2)/(M) (2). Specification/Model Label is on the side
of the tank on units that comply with California Code.
DUTY CYCLE
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
automatically. The low pressure at 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 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."
To Lock Out Power: Place a lock on the line power switch
so no one else can turn on the power.
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 more than
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.

GENERAL INFORMATION
You have purchased a complete compressor outfit
consisting of an air compressor, air tank, electric motor,
and associated controls and instruments. The outfit you
have selected is a stationary model and contains a two
stage air compressor pump.
Your new compressor outfit can be used for operating
paint sprayers, air tools, grease guns, air brushes,
caulking guns, sandblasters, inflating tires, etc.
An air pressure regulator is usually necessary for most
applications. An air line filter is normally required for
removal of moisture and oil vapor in compressed air
when a paint spray gun is used.
An in-line lubricator is often required for air tools to
prolong tool life.
Separate air transformers which combine the functions
ON-RECEIPT INSPECTION
of air regulation and/or moisture and dirt removal should
be used where applicable.
A regularly scheduled program of preventive maintenance will help provide the long life that has been
designed into your compressor outfit. Before operating
or performing any maintenance on your compressor,
refer to this manual. To keep your compressor in good
working order, refer to these publications often and
perform preventive maintenance steps as recommended.
Each air compressor outfit is carefully checked before
shipment. With improper handling, damage may result
in transit and cause problems in compressor operation.
Immediately upon arrival, check equipment for both
concealed and visible damages to avoid expenses being
incurred to correct such problems. This should be done
regardless of any visible signs of damage to the shipping
container. Report any damages to carrier and arrange for
inspection of goods immediately.

DESCRIPTION OF OPERATION
Drain Valve: At the base of the air tank 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.
Air Intake Filter: This filter is designed to clean air coming
into the pump. This filter must always be clean and ventilation
openings free from obstructions. See "Maintenance".
Air Compressor Pump: In two stage compressors, air is
first compressed to an intermediate pressure in the large bore
cylinder, and after passing through an inter-cooler, the air is
further compressed to a higher pressure in the smaller bore
cylinder. This process continues until the air tank pressure
reaches the factory set cutoff pressure. At that point the
pressure switch shuts the electric motor off.
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 Release Valve: The pressure release valve
located on the side of the pressure switch, is designed
to automatically release compressed air from the compressor
head and the outlet tube when the air compressor reaches
"cut-out" pressure or is shut off. If the air
is not released, the motor will try to start, but will be unable
to. The pressure release valve allows the motor
to restart freely. When the motor stops running, air will be
heard escaping from the valve for a few seconds. No air
should be heard leaking when the motor is running.
Pressure Switch: The pressure switch automatically
starts the motor when the air 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.
Shut-off Valve: Turn the knob counterclockwise to open
the valve and clockwise to close.
Air Tank Safety Valve: If the pressure switch does not
shut off the air compressor at its cut-out pressure setting, the
safety valve will protect against high pressure by "popping
off" at its factory set pressure (slightly higher than the
pressure switch cut-out setting).
Aftercooler Safety Valve: On two stage compressor
units, safety valve is provided to prevent over-pressurization
of the aftercooler. The valve will protect the aftercooler by
"popping off" at its factory set pressure.
Regulator: An air pressure regulator or a separate air
transformer which combines the functions of air regulation
and/or moisture and dirt removal is recommended for most
applications.
Tank Pressure Gauge: The tank pressure gauge indi-
cates the reserve air pressure in the tank. On outfits with no
pressure regulator, this is also the pressure available at the
air outlet.

INSTALLATION AND BREAK-IN PROCEDURES
Location of the Air Compressor
THE PUMP ASSEMBLY DOES NOT PROVIDE ADEQUATE STABILITY OR SUPPORT
FOR LIFTING THE UNIT. IF THE OUTFIT
MUST BE MOVED, USE THE TANK FOR
LIFTING.
This compressor should be permanently mounted in
place on a level floor. Operate the air compressor in a
clean, dry and well ventilated area. The air intake filter
must be kept clear of obstructions which could reduce air
delivery of the air compressor. The air compressor
should be located at least 12" away from walls or other
obstructions that could interfere with the flow of air
through the fan bladed flywheel. The air compressor
crankcase and head are designed with fins to provide
proper cooling.
The flywheel side of the outfit should be placed toward
the wall and protected with a totally enclosed belt guard.
In no case should the flywheel be closer than 12 to 18
inches from the wall or other obstruction that will interfere
with the flow of air through the fan bladed flywheel. The
area should allow space on all sides for air circulation
and for ease of normal maintenance. Keep the outfit
away from areas which have dirt, vapor and volatile fumes
in the atmosphere which may clog and gum the intake
filter and valves, causing inefficient operation. Where this
is not practical a remote air intake is recommended.

Note
Where a remote air intake is used,
enlarge the size of the air intake piping by one pipe size for each 10 feet of
length.
If humidity is high, an air filter can be installed to remove
excessive moisture. Closely follow instructions packaged with the filter for proper installation. It must be
installed as close as possible to the accessory.
The air compressor should be as near to air outlets as
possible in order to avoid long pipe lines. Do not place
the air compressor where heat is excessive.
To avoid voltage drop and power loss to the motor, use
extra air hose instead of an extension cord. Low voltage
can cause damage to the motor.
8—ENG
Vertical Units
Vertical air compressors must be bolted to the floor.
Bolting holes are provided in the base feet. Mount the air
compressor on a solid, level foundation. Support compressor weight evenly on all four feet. Solid shims may
be used if necessary.
INSTALLATION AND BREAK-IN PROCEDURES
Wiring Instructions
If your compressor unit is not equipped with a plug-in type
power cord, perform electrical wiring according to the
following instructions:
IMPROPER ELECTRICAL GROUNDING CAN
RESULT IN A RISK OF ELECTRICAL SHOCK.
WIRING SHOULD BE DONE BY A LICENSED
ELECTRICIAN IN ACCORDANCE WITH NATIONAL AND LOCAL CODES AND ORDINANCES.
Install the compressor outfit as close to the main power
supply as possible. This practice will avoid using long
lengths of electrical wiring for the power supply which can
cause power loss to the motor. When connecting wires
make sure that:
1.The amperage rating of the electrical box is adequate.
Refer to the Specification Chart (cover page) for your air
compressor outfit.
Wiring must be such that full motor nameplate voltage plus
or minus 10%, is available at the motor terminals during
starting. Refer to local codes for recommended wire sizes
for correct wire size and maximum wire run; undersize wire
causes high amp draw and overheating to the motor.
Electrical wiring must be located away
from hot surfaces such as the compressor
head, compressor cylinder, or compressor outlet tube.
Voltage and Circuit Protection
Refer to The Specification Chart for the voltage and circuit
protection requirements of your compressor. Use only a
fuse or circuit breaker that is the same rating as the branch
circuit the air compressor is operated on. If the compressor
is connected to a circuit protected by fuses, use only dual
element time delay fuses. See Specification Chart.
2.The supply line has the same electrical characteristics
(voltage, cycle, and phase) as motor.

INSTALLATION AND BREAK-IN PROCEDURES
Break-In Procedures
Serious damage may result if the following break-in instructions are not
closely followed.
The Break-In Procedure is required when:
A. New compressor is put into service.
B. Check valve is replaced
C. New pump is installed on tank.
1.Recheck compressor wiring. Make sure wires are
secure at all terminal connections. Free all contacts of
loose wire cuttings, etc.
2.Open the air outlet valve fully to permit air to escape
and prevent air pressure build-up in the tank during the
break-in period.
3.Position the fuse disconnect or circuit breaker to the
ON position and, if equipped, turn the ON/AUTO-OFF
switch on the pressure switch to the ON position.
4. Run the compressor for 30 minutes. Make sure the air
outlet, or globe valve, is open and there is no tank
pressure build-up.
Additional Regulators and
Controls
Since the air tank pressure is usually greater than that
which is needed, a separate regulator is usually employed
to control the air pressure ahead of any individual air driven
device.
Separate air transformers that combine the functions of air
regulation and moisture and dirt removal should be used
where applicable.
Lubrication and Oil
Multi-viscosity motor oils like 10W30, should
not be used in an air compressor. They
leave carbon deposits on critical components, thus reducing performance and compressor life. Use air compressor oil only.
See page 14 for oil recommendations.
5.Check for excessive vibration and noise. Adjust air
compressor belt guard as necessary to eliminate
chatter. Re-adjust or shim the air compressor feet, if
necessary, for proper level.
6. Close the outlet valve and let air compressor pump up
to "cut-out pressure". Turn the air compressor off and
check oil level. Add oil if necessary. Connect air hose
to air outlet adapter.
7. Check all air line fittings and connections/piping for air
leaks by applying a soap solution. Correct as necessary. Even minor leaks can cause this air compressor
to overwork, resulting in premature breakdown or
inadequate performance.
Compressors are shipped without oil. A
small amount of oil may be present in the
pump upon receipt of the air compressor.
This is due to plant testing and does not
mean that the pump contains oil. Do not
attempt to operate in order to check wiring
or for any reason without first adding oil to
the crankcase. Serious damage to the pump
can result from even very limited use without oil. Fill crankcase with recommended
oil before operating.
Remove the oil fill plug and fill the crankcase with recommended oil. Refer to the Service Instructions in this manual
for the specific oil recommended for use in your compressor unit. Replace the oil fill plug. Always fill to middle of
sight glass.
10—ENG
INSTALLATION AND BREAK-IN PROCEDURES
Piping
Plastic or PVC pipe is not designed for use
with compressed air. Regardless of its indicated pressure rating, plastic pipe can burst
from air pressure. Use only metal pipe for
air distribution lines.
Note
Where a remote air intake is used, enlarge the size of the air intake piping by
one pipe size for each 10 feet of length.
A typical compressed air distribution system as shown
below should be of sufficient pipe size to keep the
pressure drop between the supply and point of use to a
minimum. All pipes and fittings used must be certified
safe for the pressures involved. Pipe thread sealant
must be used on all threads, and all joints are to be made
up tight, since small leaks in the piping system are the
largest single cause of high operating costs.
All piping should be sloped to an accessible drain point
and all outlets should be taken from the top of the main
distribution air line so that moisture cannot enter the
outlet.
The main distribution air line should not be smaller than
the compressor air discharge valve outlet. A smaller line
will restrict the flow of air. If piping is over 100 feet long,
or if required air flow will exceed 15 SCFM, use 3/4"
piping.
Note
For underground installation, bury air
lines below the frost line and avoid
pockets where condensation can gather
and freeze. Apply pressure before underground lines are covered to make
sure all pipe joints are free from leaks.
It is recommended that a flexible coupling be installed
between the air discharge valve outlet and main air
distribution line to allow for vibration.
To remove dirt, oil and water, install a separator in the
main distribution line. Install separator a minimum of 5
to 6 feet from compressor to allow the air to cool to room
temperature before passing through the separator. Additional separators or filters may be used depending on
the application.
Liquid water occurs naturally in air lines as a result of
compression. Moisture vapor in ambient air is concentrated when pressurized and condenses when cooled in
downstream air piping. Compressed air dryers reduce
the water vapor concentration and prevent liquid water
formation in compressed air lines. Dryers are a necessary companion to filters, aftercoolers, and automatic
drains for improving the productivity of compressed air
systems.
Water and water vapor removal increases the efficiency
of air operated equipment, reduces contamination and
rusting, increases the service life of pneumatic equipment and tools, prevents air line freeze-ups, and reduces product rejects. The use of dryers and filters are
recommended when these moisture related problems
are reported to our factory or distributor service department.
11—ENG
OPERATING PROCEDURES
1. Before attaching an air hose or accessory, make sure the
outlet valve is in the closed position. On units equipped
with a pressure switch lever make sure the switch is in the
OFF position.
Compressed air from the outfit may contain
water condensation and oil mist. Do not spray
unfiltered air at an item that could be damaged by moisture or oil mist. Some air operated tools or devices may require filtered air.
Read instructions for air tool or device.
2.Attach regulator, hose and accessory. On models
without an air pressure regulator, one must be installed
before using 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 compressor on and allow tank pressure to build.
On units equipped with a pressure switch lever, place the
switch in the ON-AUTO position. The motor will stop
when tank pressure reaches "cut-out pressure".
When You Are Finished:
6. Turn the compressor unit 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. Open the drain cock valve underneath the tank and
drain water from air tank. Collect the water in a suitable
containter. Continue operating unit until all moisture is
removed from the air tank.
DRAIN TANK DAILY. WATER WILL CONDENSE
IN THE AIR TANK. IF NOT DRAINED, THE WATER WILL CORRODE AND WEAKEN THE AIR
TANK, CAUSING A RISK OF AIR TANK RUPTURE. THE AIR TANK MUST BE DRAINED PROPERLY.
11. After the water has been drained, close the drain cock.
- if the compressor is under continuous use - drain at
least once each day.
4. Open the outlet valve.
5. If an air pressure regulator is in use, open the regulator by
turning it clockwise. Adjust the regulator to the correct
pressure setting. Your outfit is ready for use.
- if the compressor is only used occasionally - drain
after each use.
Note
If drain cock valve is clogged, release air
pressure in air tank. The drain cock valve
can then be removed, cleaned and reinstalled.
12—ENG
MAINTENANCE
UNIT CYCLES AUTOMATICALLY WHEN POWER IS ON. DURING MAINTENANCE, YOU COULD BE
EXPOSED TO VOLTAGE SOURCES, COMPRESSED AIR OR MOVING PARTS. PERSONAL INJURIES
CAN OCCUR. DISCONNECT POWER SOURCE AND BLEED OFF ALL AIR TANK PRESSURE BEFORE
DOING ANY MAINTENANCE OR REPAIR. NEVER OPERATE THE UNIT WITH THE BELT GUARD
REMOVED.
To ensure efficient operation and longer life of the air compressor outfit, a routine maintenance schedule should be
prepared and followed. The following routine maintenance schedule is geared to an outfit in a normal working environment
operating on a daily basis. If necessary, the schedule should be modified to suit the conditions under which your
compressor is used. The modifications will depend upon the hours of operation and the working environment. Compressor
outfits in an extremely dirty and/or hostile environment will require a greater frequency of all maintenance checks.
A clean air compressor runs cooler and provides longer service. Clean or blow off fins and any other parts of the air
compressor that collect dust or dirt. Do not place rags, containers or other material on or against the ventilation openings
in the belt guard. Adequate ventilation is necessary to maintain proper air compressor operating temperature.
Routine Maintenance Schedule
Every 8 Hours of Operation
1. Check oil level. Add if necessary.
2. Drain water from the air tank, any moisture separators
or transformers.
Overfilling with oil will cause premature
compressor failure. Do not overfill.
3. Check for any unusual noise and/or vibration.
4. Manually check all safety valves to make sure they
are operating properly.
5. Inspect for oil leaks and repair any leaks found.
6. Clean and inspect the air intake filter; replace if
necessary.

NOTE
Keep the air filter clean at all times. Do
not operate the compressor with the air
filter removed.
A dirty air filter will not allow the compressor to operate
at full capacity. Before you use the compressor, check
the air filter to be sure it is clean. If it is dirty, replace it
with a new filter.
Oil - Checking and Changing
Overfilling with oil will cause premature
compressor failure. Do not overfill.
1. Check oil level in compressor crankcase before
each use. The oil level should be to the middle of the
oil sight glass.
2. Replace the oil after:
Single - initial 100 hours of operation - thereafter,
every 300 hours of operation.
3. Remove the oil fill and drain plugs. Collect the oil in
a suitable container.
4. Replace the oil drain plug and refill the crankcase
with recommended oil. Always fill to middle of sight
glass.
Note
It is important to maintain the proper oil
level. A low oil level reduces proper cylinder wall lubrication and increases ring
wear.

A compressor grade non-detergent oil should be used.
Most automotive detergent oils cause excessive carbon
buildup and should not be used. Please note that all units
run at a constant speed (not start and stop) and should
be lubricated by Rarus 847, Shell turbo 100, or Anderol
synthetic compressor oil. Do not use synthetic oil for the
first 300 hours. All units should be broken in on petroleum based oil.

Check Valve - Inspection and
Replacement
Remove and inspect the check valve at least once a
year or more often if the compressor is heavily used.
Moisture and other contaminants in the hot compressed
air will cause an accumulation of a carbon-like residue
on the working parts. If the valve has heavy carbon
build-up, it should be replaced. Use the following procedure to inspect, clean or replace the check valve.
1. Turn compressor off and disconnect or lock out
power source.
2. Release air pressure from the air tank.
3. Loosen the top and bottom tube nuts and remove the
outlet tube.
5. Replace the oil fill plug.
6. Start the compressor outfit and run for several
minutes. Shut the compressor down and check the
oil level. If necessary, add more oil.
14—ENG
4. Loosen pressure release tube nuts, disconnect from
check valve and move tube aside.
5. Unscrew the check valve with a wrench.
SERVICE INSTRUCTIONS
6. Check that the valve disc moves freely and that the
spring holds the disc in the upper, closed position.
The check valve may be cleaned with a solvent.
7. Apply sealant to the check valve threads. Reinstall
the check valve. Do not overtighten.
8. Replace the outlet tube and tighten top and bottom
nuts. Do not overtighten.
9. Replace the pressure release tube and tighten nuts.
Do not overtighten.
Safety Valve - Inspection and
Replacement
IF THE SAFETY VALVE DOES NOT WORK
PROPERLY, OVER-PRESSURIZATION MAY
OCCUR, CAUSING AIR TANK RUPTURE OR
EXPLOSION. OCCASIONALLY PULL THE
RING ON THE SAFETY VALVE TO MAKE
SURE THAT THE SAFETY VALVE OPERATES FREELY. IF THE VALVE IS STUCK OR
DOES NOT OPERATE SMOOTHLY, IT MUST
BE REPLACED WITH A VALVE HAVING THE
SAME PRESSURE RATING.
SERIOUS INJURY OR DAMAGE MAY OCCUR
IF PARTS OF THE BODY OR LOOSE ITEMS
GET CAUGHT IN MOVING PARTS. NEVER
OPERATE THE OUTFIT WITH THE BELT
GUARD REMOVED. THE BELT GUARD
SHOULD BE REMOVED ONLY WHEN THE
COMPRESSOR POWER IS DISCONNECTED.
The safety valve is set at the factory to a pressure
approximately 15 pounds higher than the rated pressure
of the outfit. If the pressure switch malfunctions and does
not shut off the motor automatically at maximum tank
pressure, the safety valve will protect the air tank against
excessive air pressure by popping off at its preset
pressure.
15—ENG
SERVICE INSTRUCTIONS
Adjusting Belt Tension

TROUBLESHOOTING GUIDE
PROBLEM
Motor overheating.
(Continued)
Water in pump crankcase; oil
appears milky in color.
CAUSE CORRECTION
Too many motor starts per hour. Consult Service Center.
Improper wiring gauge.
Incorrect voltage.
Current style electric motors run relatively hot under normal operating
conditions, with reasonable compressor loading. This condition is normal
and no adjustment is necessary.
Under normal operating conditions, the motor amperage draw will not
exceed the nameplate amperage rating, plus the service factor, as it appears
on the electric motor. If a condition of sustained high amperage exists, refer
to service checks above and/or consult electrician. If cause cannot be isolated
by an electrician, consult with Service Center for additional assistance.
Humid operating conditions.
Unit not reaching proper operating
temperature because the compressor runs infrequently and is oversized
for the air requirement.
Check electrical hookup and installation data or consult electrician.
NOTE
Relocate compressor outfit, or change oil frequently.
Consult Service Center.
Liquid water or moisture in air
lines.
Condensation forms in air lines when
the warm compressed air coming
from the air tank starts to cool down
as it travels through the air lines.
Install compressed air dryer sized for the flow and
dryness level required.
