will ignite a flammable gas or vapor. Never operate or repair in or near a flammable gas or vapor. Never store flammable liquids or gases in the vicinity of the compressor.

Never operate compressor without a beltguard. This unit can start automatically without warning. Personal injury or property damage could occur from contact with moving parts.

9. Do not wear loose clothing or jewelry that will get caught in the moving parts of the unit.

Compressor parts may be hot even if the unit is stopped.

10. Keep fingers away from a running compressor; fast moving and hot parts will cause injury and/or burns.

11. If the equipment should start to vibrate abnormally, STOP the engine/motor and check immediately for the cause. Vibration is generally an indication of trouble.

12. To reduce fire hazard, keep engine/motor exterior free of oil, solvent, or excessive grease.

An ASME code safe-

ty relief valve with a setting no higher than 200 psi for twostage compressors or 150 psi for single stage compressors MUST be installed in the air lines or in the tank for this compressor. The ASME safety valve must have sufficient flow and pressure ratings to protect the pressurized components from bursting. The flow rating can be found in the parts manual. The maximum safe pressure rating for the pump is 200 psi (two-stage) or 150 psi (single stage). The safety valve in the intercooler does not provide system protection.

Maximum operat-

ing pressure is 175 psi for two-stage compressors and 135 psi for single stage compressors. Do not operate with pressure switch or pilot valves set higher than 175 psi (two-stage) or 135 psi (single stage).

13. Never attempt to adjust ASME safe-

ty valve. Keep safety valve free from paint and other accumulations.

Never attempt to repair or modify a tank! Welding, drilling or any other modification will weaken the tank resulting in damage from rupture or explosion. Always replace worn, cracked or damaged tanks.

Drain liquid from tank daily.

14.

Tanks rust from moisture build-up, which weakens the tank. Make sure to drain tank regularly and inspect periodically for unsafe conditions such as rust formation and corrosion

15. Fast moving air will stir up dust and debris which may be harmful. Release air slowly when draining moisture or depressurizing the compressor system.

SPRAYING PRECAUTIONS

Do not spray flammable materials in vicinity of open flame or near ignition sources including the compressor unit.

16. Do not smoke when spraying paint, insecticides, or other flammable substances.

17. Use a face mask/respirator when spraying and spray in a well ventilated area to prevent health and fire hazards.

18. Do not direct paint or other sprayed material at the compressor. Locate compressor as far away from the spraying area as possible to minimize overspray accumulation on the compressor.

19. When spraying or cleaning with solvents or toxic chemicals, follow the instructions provided by the chemical manufacturer.

Disconnect, tag and lock out power source then release all pressure from the system before attempting to install, service, relocate or perform any maintenance.

Do not lift or move

unit without appropriately rated equipment. Be sure the unit is securely attached to lifting device used. Do not lift unit by holding onto tubes or coolers. Do not use unit to lift other attached equipment.

Never use the

wood shipping skids for mounting the compressor.

Install and operate unit at least 24” from any obstructions in a clean, well ventilated area. The surrounding air temperature should not exceed 100

F. This will ensure an unobstructed flow of air to cool compressor and allow adequate space for maintenance.

Do not locate the

compressor air inlet near steam, paint spray, sandblast areas or any other source of contamination.

NOTE: If compressor operates in a hot, moist environment, supply compressor pump with clean, dry outside air. Supply air should be piped in from external sources. For two-stage compressors only, use adapter kit (TF060502AV) to connect piping to compressor. Two adapter kits are needed for two-stage 10 and 15 HP units.

TANK MOUNTING

The tank should be bolted into a flat, even, concrete floor or on a separate concrete foundation. Vibration isolators should be used between the tank leg and the floor. Model MP345800AJ isolator pads are recommended for horizontal units. Model MP345700AJ isolator pads are recommended for vertical units. When using isolator pads, do not draw bolts tight. Allow the pads to absorb vibrations. When isolators are used, a flexible hose or coupling should be installed between the tank and service piping.

Failure to properly install the tank can lead to cracks at the welded joints and possible bursting.

PIPING

Never use plastic

(PVC) pipe for compressed air. Serious injury or death could result.

Any tube, pipe or hose connected to the unit must be able to withstand the tem-

perature generated and retain the pressure. All pressurized components of the air system must have a pressure rating higher than or equal to the 200 psi for two-stage compressors or 150 psi for single stage compressors ASME safety valve setting. Incorrect selection and installation of any tube, pipe or hose could result in bursting and injury. Connect piping system to tank using the same size fitting as the discharge port.

INSTALLING A SHUT-OFF VALVE

A shut-off valve should be installed on the discharge port of the tank to control the air flow out of the tank. The valve should be located between the tank and the piping system.

Never install a

shut-off valve between the compressor pump and the tank. Personal injury and/or equipment damage may occur. Never use reducers in discharge piping.

When creating a permanently installed system to distribute compressed air, find the total length of the system and select

pipe size from the chart. Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze.

Apply air pressure to the piping installation and make sure all joints are free from leaks BEFORE underground lines are covered. Before putting the compressor into service, find and repair all leaks in the piping, fittings and connections.

WIRING

All wiring and

electrical connections must be performed by a qualified electrician. Installations must be in accordance with local and national codes.

Overheating, short

circuiting and fire damage will result from inadequate wiring.

Wiring must be installed in accordance with National Electrical Code and local codes and standards that have been set up covering electrical apparatus and wiring. These should be consulted and local ordinances observed. Be certain that adequate wire sizes are used, and that:

1. Service is of adequate ampere rating.

2. The supply line has the same electrical characteristics (voltage, cycles and phase) as the motor.

3. The line wire is the proper size and that no other equipment is operated from the same line. The chart gives minimum recommended wire sizes for compressor installations.

Recommended wire sizes may be larger than the minimum set up by local ordinances. If so, the larger size wire should be used to prevent excessive line voltage drop. The additional wire cost is very small compared with the cost of repairing or replacing a motor electrically “starved” by the use of supply wires which are too small.

GROUNDING

Improperly grounded electrical components are shock hazards. Make sure all the components are properly grounded to prevent death or serious injury.

This product must be grounded. Grounding reduces the risk of electrical shock by providing an escape wire for the electric current if short circuit occurs. This product must be installed and operated with a power cord or cable that has a grounding wire.

MOTOR HOOKUP AND STARTER INSTALLATION

Branch circuit protection must be provided as specified in the United States National Electrical Code, Chapter 2, “Wiring Design and Protection.” Article 210, using the applicable article “For Motors and Motor Controllers,” (Article 430, Table 430-1 52).

IMPORTANT: Overload protection is required for all motors. Certain motors

have this protection built-in. To determine if a motor has built-in overload protection, refer to the frame size on the motor nameplate.

Motors with frame size R56HZ, Y56Y or L143T include built-in overload protection. No additional protection is required. Use Figure 3 wiring diagram.

Motors with frame sizes 184T, 215T, 254T or 284T DO NOT have built-in overload protection. A magnetic starter is required. Use Figure 4 wiring diagram.

To change to the alternate voltage on three phase motors with 230/460 ratings:

1. Rewire motor per data plate on motor or instruction sheet.

2. Check electric rating of magnetic starter and replace thermal overload

elements or magnetic starter as required. The voltage and amperage ratings are listed on the motor nameplate.

DIRECTION OF ROTATION NOTE: Improper rotation will result in

reduced unit life. The direction of rotation must be counterclockwise (as shown by the arrow on the flywheel) while facing the flywheel side of the pump. The motor nameplate will show wiring information for counterclockwise rotation.

The proper direction is very important. The direction of rotation of 3 phase motors can be reversed by interchanging any two motor-line leads. For single phase motors, refer to the motor nameplate.

IMPORTANT: Check motor rotation

before operating the compressor. All lubricated compressor pumps dis-

charge some condensed water and oil with the compressed air. Install appropriate water/oil removal equipment and controls as necessary for the intended application.

Failure to install

appropriate water/oil removal equipment may result in damage to machinery or workpiece.

GUARDING

The belt guard provided must be installed before operating the unit.

All moving parts must be guarded. All electrical covers must be installed before turning on the power.

LUBRICATION

THIS UNIT CON-

TAINS NO OIL. Before operating compressor, fill crankcase with compressor oil according to the oil capacity chart listed in “Replacement Parts Manual.”

Some residual oil may still be in the pump leaving a thin coat on the sight glass, however; there is not enough oil to operate the unit. Fill pump with single-viscosity, ISO100, non-detergent, compressor oil. Use part number ST126700AV compressor oil or Mobil 1

5W30 or 10W30 synthetic oil may also be used. Add oil only through the oil fill plug. Pouring oil into any other orifice will cause oil to leak and spray out during operation. Fill to the center of the sight gauge or maximum mark on dipstick (see Figure 5).

Using any other type of oil may

shorten pump life and damage valves.

RECOMMENDED BREAK-IN PERIOD

The compressor should be run continuously for one hour to allow proper seating of the piston rings.

1. Open drain cock completely and run the compressor for 60 minutes (See Figure 6).

150 psi for two-stage compressors or 120 psi for single stage compressors by opening the drain cock or an air valve connected to the tank or hose. Run the pump for an hour at a time at least once a week or more often if the condensation reoccurs.

IMPORTANT: Change oil after first 50 hours of operation.

PRESSURE SWITCH, START - STOP NOTE: This compressor has a maximum

operating pressure of 175 PSI for twostage compressors or 135 PSI for single stage compressors. Do not alter pressure settings on control components above this limit. The compressor unit starts and stops based on preset pressure switch settings. The pressure switch contains an unloader which is a small valve that vents air to allow the motor to start easily (See Figure 7).

2. Turn off the compressor and close drain cock. The compressor is now ready for use.

If the compressor is run under humid conditions for short periods of time, the humidity will condense in the crankcase and cause the oil to look creamy. Oil contaminated by condensed water will not provide adequate lubrication and must be changed immediately. Using contaminated oil will damage bearings, pistons, cylinders and rings and is not covered under warranty. To avoid water condensation in the oil, periodically run the compressor with tank pressure near

CONTINUOUS RUN OPERATION

To convert to continuous run operation a separate unloading device must be installed by the user between the pump and the tank. The existing check valve must be removed.

CRANKCASE BREATHER

During severe operating conditions or initial start-up, some oil may accumulate at the crankcase breather opening. This is normal and will diminish as the pump accumulates run time and the piston rings become fully seated.

Disconnect, tag and lock out power source then release all pressure from the system before attempting to install, service, relocate or perform any maintenance.

In order to maintain efficient operation of the compressor system, check the air filter and oil level before each

use. The ASME safety valve should also be checked daily (See Figure 8). Pull ring on safety valve and allow the ring to snap back to normal position. This valve automatically releases air if the tank pressure exceeds the preset maximum. If air leaks after the ring has been released, or the valve is stuck and cannot be actuated by the ring, the ASME safety valve must be replaced.

Do not attempt to tamper with the

ASME safety valve.

TANK

Drain liquid from tank daily.

The tank should be carefully inspected at a minimum of once a year. Look for cracks forming near the welds. If a crack is detected, remove pressure from tank immediately and replace.

COMPRESSOR LUBRICATION

See Operation. Add oil as required. The oil and oil filter should be changed every

three months or after every 500 hours of operation; whichever comes first. Only pressure lubricated pumps have an oil filter.

AIR FILTER

Never run the compressor pump without an intake air filter nor with a clogged intake air filter. Use compressed air to blow the filter clean. Do not wash or oil the element. If it cannot be blown clean, the filter must be replaced. Operating compressor with a dirty filter can cause high oil consumption and increase oil contamination in the discharge air.

INTERCOOLER (TWO-STAGE COMPRESSORS ONLY)

Intercooler fins are

sharp, always wear gloves and use care when you clean or work near the intercooler.

Weekly, check the intercooler to be sure all fittings are secure and tight. Blow all dirt, dust and other accumulations from the intercooler fins.

COMPONENTS

Turn off all power and use light air pressure to blow dust and foreign material from cylinder head, motor, fan blades, air lines, intercooler and tank on a monthly basis.

BELTS

Lock out and tag

the power then release all pressure from the tank to prevent unexpected movement of the unit.

Check belt tension every 3 months. Adjust belt tension to allow 3/8 to 1/2” deflection with normal thumb pressure. Also, align belts using a straight edge against the face of the flywheel and
