GENERAL INFORMATION

INTRODUCTION _____________________________________

This manual provides safe and reliable instructions for the installation, operation and maintenance of your Ingersoll-Rand air compressor. Carefully read this manual before attempting to operate or perform any maintenance. If you are uncertain about any of the instructions or procedures provided in this manual, contact Ingersoll-Rand. We recommend you retain this manual, and all publications provided with your air compressor, in a location which is accessible to all personnel who operate and service your compressed air equipment.

APPLICATION _______________________________________

Ingersoll-Rand’s standard two-stage lubricated air compressors are single-acting, air-cooled machines. Typical compressors are furnished as compact, self-contained, air receiver tank mounted units that are automatically regulated and driven by an electric motor or gasoline engine. An air-cooled aftercooler, low oil level shutdown switch and automatic drain valve are among the optional accessories that can be furnished. Bare compressor pumps and baseplate-mounted units are also available.

These compressors may be used for a variety of compressed air application up to 250 PSIG (17.5 kg/cm²). Application of these compressors as either a primary or supplementary source of air is virtually unlimited in industrial plants, service stations and auto repair shops. Supplementary service includes such uses as furnishing air at pressure not carried in regular shop lines, air at isolated locations, and standby service for air when larger compressors are shut down.

TWO-STAGE OPERATION_____________________________

Two-stage compressors consist of one or two first-stage cylinders with the same bore size and one second-stage cylinder with a smaller bore size.

C.C.N. : 22607402 Rev. : A Date : February 2005

http://air.irco.com

The basic principle of operation is as follows: On the suction stroke of the first-stage piston(s), air at atmospheric pressure enters the cylinders through the inlet filter(s) and then the inlet valves located in the head. On the compression stroke of the first-stage piston(s), the air is compressed to an intermediate pressure and discharged through the discharge valves(s) into common manifold(s). From the manifold(s) the air passes through the intercooler tubes, where the heat of first-stage compression is removed. On the suction stroke of the second-stage piston this cooled air enters the second-stage cylinder through the inlet valve. The compression stroke of the second-stage piston compresses the air to the final discharge pressure and forces it out through the discharge valve into the receiver tank or system. If cooling of the discharge air is required, an air-cooled aftercooler should be installed between the compressor discharge and the receiver tank or system.

For maintaining the receiver tank or system air pressure within predetermined limits, the compressor may be operated with automatic start & stop control or constant speed control regulation. The type of regulation used depends upon the application.

Before signing the delivery receipt, inspect for damage and missing parts. If damage or missing parts are apparent, make the appropriate notation on the delivery receipt, then sign the receipt. Immediately contact the carrier for an inspection.

All material must be held in the receiving location for the carrier’s inspection.

Delivery receipts that have been signed without a notation of damage or missing parts are considered to be delivered “clear.” Subsequent claims are then considered to be concealed damage claims. Settle damage claims directly with the transportation company.

If you discover damage after receiving the unit (concealed damage), the carrier must be notified within 15 days of receipt and an inspection must be requested by telephone with confirmation in writing. On concealed damage claims, the burden of establishing that the unit was damaged in transit reverts back to the claimant.

INSTALLATION

SELECTING A LOCATION_____________________________

ELECTRIC MOTOR UNITS. For most electric motor units, select a

relatively clean and dry well-lighted indoor area with plenty of space for proper ventilation, cooling air flow and accessibility. Provide 1,000 cubic feet of fresh air per 5 horsepower. Locate the unit at least 15 inches (38 cm) from walls, and make sure the main power supply is clearly identified and accessible.

Unless the electrical components of the unit are specially protected for outdoor use, do not install an electric motor unit outdoors or in an area that will expose the electrical components to rain, snow or sources of appreciable moisture.

WARNING FOR UNITS EQUIPPED

WITH ELECTRIC DRAIN VALVE

WARNING The electric drain valve incorporates arcing or

•

GASOLINE ENGINE UNITS. For gasoline engine units, keep the engine at least 3 feet (1 m) away from building walls and other equipment. Install the unit in a location with plenty of space for proper ventilation, cooling air flow and accessibility. Do not install or operate a gasoline engine unit in a confined area.

AMBIENT TEMPERATURE CONSIDERATIONS. Ideal operating temperatures are between 32°F and 100°F (0°C and 37.8°C). If temperatures consistently drop below 32°F (0°C), install the compressor in a heated area. If this is not possible, you must protect safety/relief valves and drain valves from freezing. If temperatures are consistently below 40°F (4.4°C), consider installing an external crankcase heater kit, especially if the compressor has difficulty starting.

•

CAUTION Never operate the compressor in temperatures

HUMID AREAS. In frequently humid areas, moisture may form in

the pump and produce sludge in the lubricant, causing running parts to wear out prematurely. Excessive moisture is especially likely to occur if the unit is located in an unheated area that is subject to large temperature changes.

Two signs of excessive humidity are external condensation on the pump when it cools down and a “milky” appearance in petroleum lubricant.

You may be able to prevent moisture from forming in the pump by increasing ventilation, operating for longer intervals or installing an external crankcase heater kit.

NOISE CONSIDERATIONS. Consult local officials for information regarding acceptable noise levels in your area. To reduce excessive noise, use vibration isolator pads or intake silencers, relocate the unit or construct total enclosures or baffle walls.

sparking parts, such as snap switches, receptacles and the like that tend to produce arcs or sparks and, therefore, when located in a garage, the compressor should be in a room or enclosure provided for the purpose, or the electric drain valve should be 18 inches (457 mm) or more above the floor.

below -15°F (-26.1°C) or above 125°F (51.0°C).

MOUNTING _________________________________________

WARNING Remove the unit from the skid before mounting.

•

ELECTRIC MOTOR UNITS. Bolt the unit to a firm, level foundation (such as a concrete floor). Do not bolt uneven feet tightly to the foundation, as this will cause excessive stress on the receiver tank. Use metal shims under the “short” feet if necessary.

Typical Permanent Mounting (Customer Supplied Hardware)

GASOLINE ENGINE UNITS. Bolt the unit to a firm, level foundation. Do not bolt uneven feet tightly to the foundation, as this will cause excessive stress on the receiver tank. Use metal shims under the “short” feet if necessary. Gasoline engine units mounted on truck beds must be fastened securely without applying excessive stress on the receiver tank. We recommend installing a vibration isolator kit with gasoline engine models.

INSTALLING REMOTE AIR INLET PIPING _______________

• CAUTION Do not operate the unit without air inlet filtration.

If the air around the unit is relatively free of dirt, install the air inlet filter at the inlet connection at the pump. If the air is dirty, pipe the filter to a source of clean air. Use PVC plastic tubes for remote inlet piping. Do not use black pipe or galvanized pipe, as these promote sweating and rust. Consider installing an in-line type filter for ease of cleaning and replacement. Make the line as short and direct as possible and as large, or larger, than the diameter of the inlet connection on the pump. Do not install piping with a diameter lower than that of the pump intake.

Increase the pipe diameter one size for every 10 feet (3 m) of length or every 90° bend. Make sure the piping is adequately braced.

If you pipe the filter outdoors, cover it with a hood to prevent the entrance of rain or snow.

Heavy duty filter elements and filtration equipment are available for fine airborne dust, such as cement and rock dust.

D = ADD level on units with sight glass.

E = ADD level on units with dipstick.

F = FULL level on units with dipstick.

LOW OIL LEVEL SWITCH _____________________________

A float activated low oil level switch may be installed to protect your unit against damage due to insufficient compressor oil level. Low oil level in the compressor crankcase causes the switch contacts to open, thus shutting the unit down until the proper oil level has been restored.

Proper protection against low oil level depends on proper adjustment of the low oil level switch. During the initial run, stop the unit and drain one quart of oil from the compressor crankcase into a suitable clean container. Listen for the switch to click or check the switch with a continuity tester.

The float sometimes gets cocked or stuck during shipping. If the float is cocked or stuck, open the disconnect switch, drain the remaining oil, remove the crankcase cover and then free the float. Reassemble and then reuse the same oil.

NOTE If the float is cocked in the low position, the unit

cannot start.

OPERATION

INTERMITTENT DUTY FORMULA ______________________

Units operating above 200 PSIG are to be operated according to the "Intermittent Duty Formula."

INTERMITTENT DUTY FORMULA

Pump-up time should not ordinarily exceed thirty (30) minutes or be less than ten (10) minutes. Shutdown periods between cycles of operation should be at least equal to the pump-up time. Note: When the compressor is regulated by constant speed control, the shutdown period is the time the compressor is operating unloaded.

A pump-up time limit with the following cool-down period is recommended to protect the valves and heads against stabilized high operating temperatures, which could rapidly build up carbon in these areas.

All inquiries for high-pressure compressor application where the "use" cycle differs from the "Intermittent Duty Formula" should be referred to Ingersoll-Rand.

START-UP (ELECTRIC MOTOR DRIVEN MODELS) _______

1. Close the service valve.

2. Release any remaining tank pressure by slowly opening the manual

COMPRESSOR CONTROLS ___________________________

AUTOMATIC START & STOP CONTROL. This type of control

applies to electric motor driven models under 10 horsepower.

NOTE Automatic Start & Stop Control is intended for use

When the receiver tank pressure reaches the factory pre-set maximum pressure (usually 175 PSIG), the pressure switch stops the unit. When the receiver tank pressure drops below the factory pre-set minimum (usually 135 PSIG), the pressure switch resets and restarts the unit.

CONSTANT SPEED CONTROL. This type of control applies to gasoline engine units.

When the receiver tank pressure reaches the factory pre-set maximum pressure (usually 175 PSIG), the unloader slows down the engine and the unit stops pumping. When the receiver tank pressure drops to the factory pre-set minimum (usually 145 PSIG), the unloader resets, the engine returns to full speed, and the unit resumes pumping.

DUAL CONTROL. This type of control applies to electric motor units over 10 horsepower. Select either automatic start and stop control or constant speed control by adjusting the knob on the auxiliary valve. For automatic start and stop control, turn the knob on the auxiliary valve fully clockwise to disable the auxiliary valve. The pressure switch will then start and stop the unit.

5. Note the pressure gauge reading at which the unit cuts out.

6. Repeat the adjustment procedure if necessary.

The minimum possible differential is approximately 20% of cutout pressure. It is advisable to have as wide a differential as possible to avoid frequent starting and stopping of the unit. Note the pressure gauge reading at which the unit cuts-out and re-establish this point if necessary.

Note the interaction between the range and differential adjustments, i.e., if the cut-out is increased, the differential will also increase, or if the differential is narrowed, the cut-out will be reduced, etc. These factors must be considered when adjusting the switch and compensated for accordingly.

STARTING UNLOADING SYSTEM ______________________

The starting unloading feature exists on certain models. The purpose of the system is to relieve cylinder pressure when the unit stops, permitting it to start against a light load. A light load increases the life of the driver and belts and also reduces the possibility of tripping the overload relay. The system operates in the following manner:

The centrifugal unloader is attached to the end of the crankshaft as shown in the following illustrations.

When the unit starts, centrifugal force acts upon the unloader weights and they swing outward. This permits the plunger and thrust pin to move inward and the pilot valve to close. The escape path to atmosphere for the cylinder pressure is now closed and the compressor pumps air in a normal manner.

When the unit stops, the weights retract, permitting the thrust pin spring to move the plunger and thrust pin outward. The thrust pin opens the pilot valve and the trapped air pressure escapes from the cylinder and intercooler through a passage in the frame end cover, through the unloader tube and to atmosphere through the inlet filter/silencer.

Position of weight and thrust pin when unit is operating.

Position of weight and thrust pin when unit is stopped.

BREATHER/UNLOADER BY-PASS _____________________

The breather/unloader by-pass tube lines eliminates air pressure build-up in the compressor frame by providing a passage for the air to escape through the inlet unloader (if opened) or (if closed) through the check valve, therefore, by-passing the inlet unloader and escaping to atmosphere through the inlet filter/silencer.

OIL CONSUMPTION CHECK___________________________

A rule of thumb in determining a "passing grade" for oil consumption is to consider consumption at or above 50 horsepower-hours per ounce to be acceptable.

The formula is as follows:

Horsepower X

Ounces of Oil Used

Hours of Operation

To apply this formula, consider the size of the machine. In the following example, a 5 horsepower compressor uses 2 ounces of oil every 20 hours of operation.

5 Horsepower X 20 Hours of

Operation

The compressor in the example passes the oil consumption test.

NOTE New or rebuilt compressor pumps will discharge

PILOT VALVE ADJUSTMENT __________________________

If the pilot valve tube line is excessively hot, it is a good indication that the pilot valve is leaking and adjustment is required.

To adjust the pilot valve, proceed as follows:

1. Stop the unit and disconnect and tag the electrical supply main

switch to prevent accidental start-up.

2. Remove the pilot valve tube and the tube fittings.

3. Remove the pilot valve body and all existing shims.

4. Screw the pilot valve body back into the frame end cover (without

any shims) until contact with the thrust pin is felt. Advance the pilot valve body 1/4 to 1/2 turn more.

If contact with the thrust pin cannot be felt, the following steps may be necessary to locate the contact point:

1. Insert a small instrument (punch, rod, nail, etc.) into the end of the

pilot valve until it contacts the valve stem.

2. While still inserted in the pilot valve, make a mark on the instrument

even with the outside edge of the pilot valve body.

3. Keeping the instrument pressed lightly against the valve stem, screw

the pilot valve body into the frame end cover. When the mark on the instrument starts moving out away from the edge of the pilot valve body, contact has been made with the thrust pin.

4. Advance the pilot valve body 1/4 to 1/2 turn more and proceed with

step five.

5. Measure the gap between the pilot valve body and the frame end

cover.

6. Remove the pilot valve body and add enough shims to fill the gap

measured in step five.

7. Screw the pilot valve body back into the frame end cover until the

body is tight on the shims.

8. Reconnect the pilot valve tube and tube fittings.

MAINTENANCE

• WARNING Before performing maintenance, release air pressure from the system and disconnect, lock and tag the main power supply or disconnect the wire from the engine spark plug.

NOTE All compressed air systems contain maintenance

parts (e.g. lubricating oil, filters, separators) which are periodically replaced. These used parts may be, or may contain, substances that are regulated and must be disposed of in accordance with local, state, and federal laws and regulations.

NOTE Take note of the positions and locations of parts

during disassembly to make reassembly easier. The assembly sequences and parts illustrated may differ for your particular unit.

NOTE Any service operations not explained in this manual

should be performed by an authorized service representative.

NOTE Reference the engine owner's manual for engine

care information.

NOTE The following maintenance schedule has been

developed for typical applications. Maintenance intervals should be shortened in harsher environments.

BELT ADJUSTMENT _________________________________

CHECKING BELT TENSION. Check belt tension should be

occasionally, especially if looseness is suspected. New belts must also be properly tensioned upon installation.

TENSIONING BELTS. Belt tensioning can be achieved by loosening the motor or engine anchor screws, pushing the motor or engine away from the pump, and retightening the motor or engine anchor screws. Some units are equipped with a belt tensioning bolt that, when turned, pulls the motor or engine away from the pump. Otherwise, the motor can be easily moved by placing a prying tool beneath it. A commercially available spreader or other belt tensioning device can also be helpful.

Follow the procedures outlined below to correctly set and measure belt tension on electric motor and gas engine models including 2340, 2475, and 2545 (with "A" belt type only). Refer to the following illustration for a visual representation.

FILTER INSPECTION & CLEANING_____________________

1. Unscrew and remove the wing nut (A) securing the filter housing (B)

to its base (C).

2. Remove the filter housing and withdraw the old filter element (D).

Clean the element with a jet of air or vacuum.

3. Replace the filter element and housing, securing it in place with the

wing nut previously removed.

OIL CHANGE ________________________________________

1. Remove the oil drain plug (A) and allow the lubricant to drain into a

suitable container.

2. Replace the oil drain plug.

3. Follow the filling procedures in OPERATION section.

1. Lay a straight edge across the top outer surface of the belt drive

from pulley to sheave.

2. At the center of the span, perpendicular to the belt, apply pressure

to the outer surface of the belt with a tension gauge. Force the belt to the deflection indicated in the BELT TENSION TABLE in the DIAGRAMS & TABLES section. Compare the reading on the tension gauge to the table.

Follow the procedures outlined below to correctly set and measure tension on 7.5 through 30 horsepower models 2545, 7100, 15T and 3000 with "B" and "C" belt types.

1. Measure the span length (t) of the drive.

2. Determine the amount of deflection (in inches) required to measure

deflection force (in pounds) by multiplying the span length (t) by 1/64. For example, a 32” span length multiplied by 1/64 equals 1/2” of deflection required to measure deflection force.

3. Lay a straight edge across the top outer surface of the belt drive

from pulley to sheave.

4. At the center of the span, perpendicular to the belt, apply pressure

to the outer surface of the belt with a tension gauge. Force the belt to the predetermined deflection calculated in step 2. Compare the reading on the tension gauge to the BELT TENSION TABLE in the DIAGRAMS & TABLES section.

Ensure the pulley and sheave are properly aligned and the motor anchor screws are adequately retightened prior to restarting the compressor.

CAUTION Improper pulley/sheave alignment and belt tension

•

To prevent these problems from occurring, ensure the pulley and sheave are aligned and belt tension is satisfactory after installing new belts or tensioning existing belts.

can result in motor overload, excessive vibration, and premature belt and/or bearing failure.

5. Replace plug and tighten with wrench.

Position of weight and thrust pin when unit is operating.

6. When putting the EDV-2000 back into service, press the TEST

button to confirm proper function.

TANK INSPECTION __________________________________

The life of an air receiver tank is dependent upon several factors including, but not limited to, operating conditions, ambient environments, and the level of maintenance. The exact effect of these factors on tank life is difficult to predict; therefore, Ingersoll-Rand recommends that you schedule a certified tank inspection within the first five years of compressor service. To arrange a tank inspection, contact Ingersoll-Rand.

If the tank has not been inspected within the first 10 years of compressor service, the receiver must be taken out of service until it has passed inspection. Tanks that fail to meet requirements must be replaced.

• WARNING Failure to replace a rusted air receiver tank could result in air receiver tank rupture or explosion, which could cause substantial property damage, severe personal injury, or death. Never modify or repair tank. Obtain replacement from service center.
