SAFETY AND OPERATION PRECAUTIONS

_______________________________________________________________________________________

Because an air compressor is a piece of machinery with moving and rotating parts, the same precautions should be
observed as with any piece of machinery of this type where carelessness in operation or maintenance is hazardous to
personnel. In addition to the many obvious safety rules that should be followed with this type of machinery, the additional
safety precautions as listed below must be observed:

1. Read all instructions completely before operating air compressor or unit.

2. For installation, follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).

3. Electric motors must be securely and adequately grounded. This can be accomplished by wiring with a grounded,
metal-clad raceway system to the starter; by using a separate ground wire connected to the bare metal of the
motor frame; or other suitable means.

4. Protect the power cable from coming in contact with sharp objects. Do not kink power cable and never allow the
cable to come in contact with oil, grease, hot surfaces, or chemicals.

5. Make certain that the power source conforms to the requirements of your equipment.

6. Pull main electrical disconnect switch and disconnect any separate control lines, if used, before attempting to work
or perform maintenance on the air compressor or unit. "Lock out" or "Tag out" all power sources.

7. Do not attempt to remove any compressor parts without first relieving the entire system of pressure.

8. Do not attempt to service any part while machine is in an operational mode.

9. Do not operate the compressor at pressures in excess of its rating.

10. Do not operate compressor at speeds in excess of its rating.

11. Periodically check all safety devices for proper operation. Do not change pressure setting or restrict operation
in any way.

12. Be sure no tools, or rags or loose parts are left on the compressor or drive parts.

13. Do not use flammable solvents for cleaning the air inlet filter or element and other parts.

14. Exercise cleanliness during maintenance and when making repairs. Keep dirt away from parts by covering parts
and exposed openings with clean cloth or Kraft paper.

15. Do not operate the compressor without guards, shields and screens in place.

16. Do not install a shut-off valve in the discharge line, unless a pressure relief valve, of proper design and size, is
installed in the line between the compressor unit and shut-off valve.

17. Do not operate compressor in areas where there is a possibility of ingesting flammable or toxic fumes.

18. Be careful when touching the exterior of a recently run motor - it may be hot enough to be painful or cause injury.
With modern motors this condition is normal if operated at rated load - modern motors are built to operate at
higher temperatures.

19. Inspect unit daily to observe and correct any unsafe operating conditions found.

20. Do not "play around" with compressed air, nor direct air stream at body, because this can cause injuries.

21. Compressed air from this machine absolutely must not be used for food processing or breathing air without
adequate downstream filters, purifiers and controls.

22. Always use an air pressure regulating device at the point of use, and do not use air pressure greater than marked
maximum pressure of attachment.

23. Check hoses for weak or worn condition before each use and make certain that all connections are secure.

24. Always wear safety glasses when using compressed air gun.

The user of any air compressor package manufactured by Champion – A Gardner Denver Co., is hereby warned that
failure to follow the preceding Safety and Operation Precautions can result in injuries or equipment damage. However,
Champion – A Gardner Denver Co., does not state as fact or does not mean to imply that the preceding list of Safety
and Operating Precautions is all inclusive, and further that the observance of this list will prevent all injuries or equipment
damage.

INSTALLATION

1. Permanently installed compressors must be located in a clean, well ventilated dry room so compressor receives

adequate supply of fresh, clean, cool and dry air. It is recommended that a compressor, used for painting, be located
in a separate room from that area wherein body sanding and painting is done. Abrasive particles or paint, found to
have clogged the air intake filters and intake valves, shall automatically void warranty.

2. Compressors should never be located so close to a wall or other obstruction that flow of air through the fan bladed
flywheel, which cools the compressor, is impeded. Permanently mounted units should have flywheel at least 12" from
wall.

3. Place stationary compressors on firm level ground or flooring. Permanent installa-tions require bolting to floor. Bolt
holes in tank or base feet are provided. Before bolting or lagging down, shim compressor level. Avoid putting a
stress on a tank foot by pulling it down to floor. This will only result in abnormal vibration, and possible cracking of
Air Receiver. It is recommended that optional vibro-isolator pads be installed on unit. Tanks bolted directly to a
concrete floor without padding will not be warranted against cracking. Champion vibro-isolators must be used for
extended warranty to apply to ASME air receivers.

4. If installing a bare pump or a base mounted unit, make certain the system has adequate pressure limiting controls.
Controls could be a pressure switch for start/stop operation or a pilot valve for continuous operation. If a pilot valve
is used, the compressor must be equipped with head unloaders. Control air must be piped from the air receiver to
the pilot valve.

DANGER

Do not install isolating valves betweencompressor outlet and air receiver. This will cause excessive
pressure if valve is closed, and cause injury and equipment damage.

WARNING

Always use an air pressure regulating device at the point of use. Failure to do so can result in injury or
equipment damage.

CAUTION

● Do not install in an area where ambient temperature is below 32 degrees F or above 100 degrees F.

● Do not install unit in an area where air is dirty and/or chemical laden.

● Unit is not to be installed outdoors.

ELECTRICAL POWER SUPPLY

It is essential that the power supply and the supply wiring are adequately sized and that the voltage correspond to
the unit specifications.
All wiring should be performed by a licensed electrician or electrical contractor. Wiring must meet applicable codes
for area of installation.
Recommended electrical wiring specifi-cations are listed in "Specifications" section.
If ordered with a mounted starter, compressor unit is pre-wired at factory. It is necessary only to bring lines
fromproperly sized disconnect switch to magnetic starter mounted on compressor, and attach to terminals as
indicated on schematic diagram located inside cover of control. Be sure that power circuit and voltage correspond
with the specifications

.

CAUTION

Wiring must be such that when viewing compressor from opposite shaft end, rotation of shaft is clockwise
as shown by arrow on guard. Wrong direction rotation for any length of time will result in damage to
compressor.

8

INSTALLATION (CONT’D)

GROUNDING INSTRUCTIONS

This product should be connected to a grounded, metallic, permanent wiring system, or an equipment-

grounded terminal or lead on the product.

AIR LINE PIPING

Connection to air system should be of the same size, or larger, than discharge pipe out of unit. See

recommended piping sizes listed in "Specifications" section. A union connection to the unit and water drop leg
is recommended. Install a flexible connector between the discharge of the unit and the plant air piping. Plant air
piping should be periodically inspected for leaks using a soap and water solution for detection on all pipe joints.
Air leaks waste energy and are expensive.

PREPARATION FOR INITIAL START-UP AND OPERATION

1. Pull main disconnect switch to unit and tag out to assure that no power is coming into the unit. Connect
power leads to starter.

WARNING

Do not attempt to operate compressor on voltage other than that specified on order or on compressor
motor.

2. Check compressor oil level. Add oil as required. See section on "Oil Specifications".

3. Inspect unit for any visible signs of damage that would have occurred in shipment or during installation.

4. Activate main disconnect switch.

5. "Jog" motor and check for proper rotation by direction of arrow. If rotation is wrong, reverse input
connections on the magnetic starter.

6. Close receiver outlet hand valve and start unit.

7. With receiver hand valve closed, let machine pump up to operating pressure. At this stage the automatic
controls will take over. Check for proper cycling operation.

8. Check for proper operation of any options, e.g. LOSC or head unloaders with pilot valve. Refer to individual
option instruction sheet.

9. When the initial run period has shown no operating problems, shut unit down and recheck oil level.

10. Open receiver hand valve. The air compressor unit is now ready for use.

GUIDE TO MAINTENANCE

To obtain reliable and satisfactory service, this unit requires a consistent preventive maintenance schedule.
Maintenance schedule pages are included in the back of this manual to aid in keeping the proper records.

WARNING

Before performing any maintenance function, switch main disconnect switch to "off" position to assure
no power is entering unit. "Lock Out" or "Tag Out" all sources of power. Be sure all air pressure in unit
is relieved. Failure to do this may result in injury or equipment damage.

DAILY MAINTENANCE

1. Check oil level of both compressor and engine if so equipped. Add quality lubricating oil as required. See
Section on "Oil Specifications".

2. Drain moisture from tank by opening tank drain valve located in bottom of tank. Do not open drain valve
if tank pressure exceeds 25 PSIG.

3. Turn off compressor at the end of each day's operation. Turn off power supply at wall switch.

WEEKLY MAINTENANCE

1. Clean dust and foreign matter from cylinder head, motor, fan blade, air lines, intercooler and tank.

2. Remove and clean intake air filters.

WARNING

Do not exceed 15 PSIG nozzle pressure when cleaning element parts with compressed air. Do not direct
compressed air against human skin. Serious injury could result. Never wash elements in fuel oil,
gasoline or flammable solvent.

3. Check V-belts for tightness. The V-belts must be tight enough to transmit the necessary power to the
compressor. Adjust the V-belts as follows:

Remove bolts and guard to access compressor drive.

Loosen mounting hardware which secures motor to base. Slide motor within slots of baseplate to desired
position.

Apply pressure with finger to one belt at midpoint span. Tension is correct if top of belt aligns with bottom
of adjacent belt. Make further adjustments if necessary.

Check the alignment of pulleys. Adjust if necessary.

Tighten mounting hardware to secure motor on base.

Re-install guard and secure with bolts.

WARNING

Never operate unit without belt guard in place. Removal will expose rotating parts which can cause
injury or equipment damage.

10

EVERY 90 DAYS OR 500 HOURS MAINTENANCE

1. Change crankcase oil. Use type and grade oil as specified in the section on "Compressor Oil
Specifications".

2. Check entire system for air leakage around fittings, connections, and gaskets, using soap solution and
brush.

3. Tighten nuts and capscrews as required.

4. Check and clean compressor valves, replace springs, discs and seats when worn or damaged.

CAUTION

Valves must be reinstalled in original position. Valve gaskets should be replaced each time valves are
serviced.

5. Pull ring on all pressure relief valves to assure proper operation.

GENERAL MAINTENANCE NOTES

PRESSURE RELIEF VALVE: The pressure relief valve is an automatic pop valve. Each valve is properly

adjusted for the maximum pressure permitted by tank specifications and working pressure of the unit on
which it is installed. If it should pop, it will be necessary to drain all the air out of the tank in order to reseat
properly. Do not readjust.

TANK DRAIN VALVE: Drain valve is located at bottom of tank. Open drain valve daily to drain condensation.

Do not open drain valve if tank pressure exceeds 25 PSIG. The automatic tank drain equipped
compressor requires draining manually once a week.

PRESSURE SWITCH: The pressure switch is automatic and will start compressor at low pressure and stop

when the maximum pressure is reached. It is adjusted to start and stop compressor at the proper pressure
for the unit on which it is installed. Do not readjust.

BELTS: Drive belts must be kept tight enough to prevent slipping. If belts slip or squeak, see V-belt

maintenance in preceding section.

CAUTION

If belts are too tight, overload will be put on motor and motor bearings.

COMPRESSOR VALVES: If compressor fails to pump air or seems slow in filling up tank, disconnect unit from

power source and remove valves and clean thoroughly, using compressed air and a soft wire brush. After
cleaning exceptional care must be taken that all parts are replaced in exactly the same position and all
joints must be tight or the compressor will not function properly. When all valves are replaced and
connections tight, close hand valve at tank outlet for final test. Valve gaskets should be replaced each time
valves are removed from pump.

11

GENERAL MAINTENANCE NOTES (CONT'D)

CENTRIFUGAL UNLOADER AND UNLOADER PRESSURE RELEASE VALVE:

The centrifugal unloader Is operated by two governor weights. It is totally enclosed and lubricated from
the crankcase of the compressor. When compressor starts, the governor weights automatically open
compressing the main spring, allowing the unloader pressure release valve to close. When the compressor
stops, the main spring returns the governor weights to normal position opening the unloader pressure
release valve and unloading the compressor. This prevents overloading the motor when starting. If air
continues to escape through the governor or unloader pressure release valve while operating, this is an
indication that the unloader pressure release valve is not closing tightly and may be held open by foreign
substance which has lodged on the seat. In order to correct this, remove the governor release valve cap,
giving access to unloader pressure release valve spring and ball. Clean thoroughly and return parts in the
same order in which they were removed. Loose drive belts can also cause unloader to leak by preventing
the compressor from reaching proper speed. (See "BELTS" above.)

CHECK VALVE:

The check valve closes when the compressor stops operating, preventing air from flowing out of the tank
through the pressure release valve. After the compressor stops operating, if air continues to escape
through the release valve, it is an indication that the check valve is leaking. This can be corrected by
removing check valve and cleaning disc and seat. If check valve is worn badly, replace same.

WARNING

Before removing check valve be sure all air pressure in unit is relieved and power is disconnected. Failure
to do so may result in injury or equipment damage.

THE INTERSTAGE PRESSURE RELIEF VALVE is provided to protect against interstage over pressure and is

factory set for maximum pressure of 75 PSIG.

DO NOT RESET

If the pressure relief valve pops, it indicates trouble. Shut down the unit immediately and determine and
correct the malfunction. Inspect the head valves. Serious damage can result if not corrected and can lead
to
complete destruction of the unit. Tampering with the interstage pressure relief valve, or plugging the
opening destroys the protection provided and voids all warranty.

LUBRICATION OF COMPRESSOR:

Fill crankcase to proper level as indicated by oil sight gauge. Keep crankcase filled as required by usage.

12

COMPRESSOR OIL SPECIFICATIONS

1. AIR COMPRESSOR

Compressors shipped on units are factory filled with ISO 100 reciprocating compressor oil. Compressors
shipped as basic (pump only) do not have any oil in the crankcase. Be sure to add oil to these pumps prior
to start-up.

It is recommended that this compressor be maintained using the ISO 100 recip oil for ambient
temperatures above 32 degrees F. This is a 30 weight, non-detergent industrial oil with rust and oxidation
inhibitors specially formulated for reciprocating compressors. Contact your distributor for information and
purchase of this oil. For temperatures below 32 degrees F, use an ISO 68 compressor oil. A separate
list of acceptable oils can be obtained from the distributor's Service Department.

NOTES:

1. Do not mix oil types, weights, or brands. Consult factory for the use of synthetic lubricants.

2. For the first 100 hours of compressor operation, a careful and regular check of the oil level should
be made. Maintain oil level at the full line.

2. ELECTRIC MOTORS
Electric motors are equipped with sealed-for-life bearings and require no additional lubrication.

13

TROUBLE SHOOTING CHART FOR COMPRESSOR

EXPLANATION OF TROUBLE SHOOTING GUIDE

1/2. Check all fuses and switches on lines to motor to be sure it is receiving power. Check for loose or

faulty wires.

3. A magnetic starter embodies a reset button which may be used to place the motor back in service
after some unusual power conditions.

4/5. A pressure switch uses a diaphragm to open and close a set of points. Points may become pitted

or dirty through use. Clean by "touching up" with sandpaper or replace. See instructions in pressure
switch cover.

WARNING

Disconnect unit from power source before checking pressure switch.

6. Low voltage is prime cause of motor trouble. Ask you power company to test for low voltage.

7. Most electric motors are of the sealed bearing type. Check motor manufacturer's recommendation.

8. Water in the form of vapor is compressed along with incoming air and condenses in tank. Tank must
be drained daily so that full storage capacity of tank may be used. To drain, relieve tank pressure,
open valve at bottom of horizontal or vertical tank. If compressor is equipped with automatic tank
drain, drain manually once a week.

WARNING

Do not open drain valve if tank pressure exceeds 25 PSIG.

9. The fins on the cylinder and tubing should be free of dirt which acts as an insulation. This is easily
done by periodically blowing them clean or through the use of a wire brush.

9. "V” belts must be tight enough to transmit the necessary power to the compressor. If too tight they
will overload the motor. If, by pushing down on one belt, its top lines up with the bottom of the belt
next to it, the tension is correct. Should it be necessary to change the tension, slide the engine or
motor in slots provided in tank baseplate to desired position.

WARNING

Disconnect unit from power source before checking or adjusting belts. Always reinstall belt guard
after adjusting belts.

11. The fan blade flywheel must rotate in the direction shown by the arrows.

12. Compressor valves may become fouled by carbon or other foreign matter. To service, remove
manifold and extract valve. Remove screw in center of valve and clean all parts. Seat and disc may
be lapped in on fine sandpaper if badly carboned. If a smooth finish cannot be obtained, replace with
new parts. Reassemble and install, taking caution that all parts are returned to their original position
with screw head up.

13. All air lines from compressor to tank and from tank to air operated devices should be tight. A soap
solution will show bubbles when put on a leaky joint. At 175 PSIG a 1/32" hole will allow almost 3
cubic feet per minute of air to escape.

14. Pilot Valve adjustment is found on page 23.

15. Check pilot valve for loose connections.

16. The centrifugal unloader valve may become fouled by foreign matter. To clean, unscrew hex cap on
end of unloader, remove spring and ball, to remove ball, you may need to "rock" flywheel. Clean or
replace if necessary.

15

EXPLANATION OF TROUBLE SHOOTING GUIDE (CONT'D.)

17/18. Before servicing check valve, be sure pressure in tank is ZERO. Replace check valve.

19. Badly worn compressors which are pumping oil may deposit carbon within after-cooler tube and check
valve, restricting flow of air and possibly plugging these parts completely. These parts should be
cleaned or replaced.

WARNING

Disconnect unit from power source and relieve tank pressure before servicing these components.

20. Motor pulley and flywheel must be in line to prevent wear on sides of belts. If misaligned, disconnect
unit from power source and move pulley in or out by loosening set screw on key and tapping pulley
in appropriate direction.

WARNING

Disconnect power source before adjusting pulley.

21. Intake filter should be cleaned periodically to allow unrestricted flow of entering air. To service filter,
remove wing nut, metal cover and filter element. Element may be blown clean with an air nozzle if
moderately dusty. Heavily fouled elements should be replaced. Never clean element with fuel oil,
gasoline or flammable solvent.

22. Cool running and long life can be assured by careful attention to crankcase oil. Check frequently and
change as indicated on compressor data sheet.

CONSTANT SPEED HEAD UNLOADER KIT Z9144

For Air Compressor Pump Models R-10D and R-15B

NOTE: This is optional equipment and may not be included on your unit.

The purpose of constant speed unloading is to provide a means of stopping or starting the compression of air by the compressor
without stopping or starting the electric motor or gasoline engine after each cycle.

To accomplish this, an air pilot valve is used to replace the pressure switch used for stop-start operation. The pilot valve senses
storage tank pressure, and when the pressure is raised to a predetermined setting, this air is released to an intake valve hold-open
mechanism. The compressor stops compressing air and runs free until the pilot valve senses that the pressure in the tank has
dropped to the predetermined setting. At this time the air is released from the intake valve hold-open mechanism, and the
compressor starts compressing air again.

The parts called out below replace or are substituted for those found in the regular parts list.

The Pilot Valve is designed to act as an automatic "on" and "off" air switch. When in the "on" position it allows air to flow
from the tank through the valve to some device such as a compressor suction unloader, thus actuating it. In the "off"
position this valve stops the flow of air through the valve and releases the pressure in the line to the device.

The Pilot Valve works as follows: Tank air pressure acts on the bottom of the valve. When pressure is great enough
to overcome spring force holding valve down on lower seat, it lifts off seat and allows air to flow around valve and out
through side opening in Pilot Valve. When valve lifts off lower seat it moves up and seats on upper seat where it is held
by tank pressure. When pressure in tank and on valve drops, spring forces valve back down on lower seat. Air in line
to device being actuated can then escape through upper seat and out vent hole. The pressure at which the Pilot Valve
is "on" or "off" is controlled by the spring which has been installed at the factory. A small adjustment can be made in
the field by changing the spring force by compressing the spring more or less with the adjusting screw provided on the
Pilot Valve.

COMPRESSOR PILOT VALVEPRESSURE ADJUSTMENT

Proceed with the following instructions while compressor is running:

1. Loosen locknut (4) and back off several turns. Do not turn differential adjuster (3).

2. Check reading on the tank pressure gauge. Set the compressor maximum pressure at 170 psig. Turn threaded
cap clockwise to increase pressure or counterclockwise to decrease pressure.

3. After pressure is set, tighten locknut (4). Be careful not to move the threaded cap (1).

COMPRESSOR PILOT VALVE DIFFERENTIAL PRESSURE ADJUSTMENT

Proceed with the following instructions while compressor is running:

1. Loosen locknut (2) and back off several turns.

2. Check reading on the tank pressure gauge. Set the pressure to 30 psig differential (unload at 170 psig, reload
at 140 psig). Turn nut (3) clockwise to increase differential pressure or counter-clockwise to decrease differential
pressure.

3. After pressure is set, tighten locknut (2). Be careful not to move nut (3).
