Important Safety Information (Continued)
BREATHABLE AIR WARNING
This compressor/pump is not equipped and should not be used “as is” to supply breathing quality
air. For any application of air for human consumption, the air compressor/pump will need to be
fitted with suitable in-line safety and alarm equipment. This additional equipment is necessary to
properly filter and purify the air to meet minimal specifications for Grade D breathing as described
in Compressed Gas Association Commodity Specification G 7.1, OSHA 29 CFR 1910. 134, and/or
Canadian Standards Associations (CSA).
DISCLAIMER OF WARRANTIES
In the event the compressor is used for the purpose of breathing air application and proper in-line
safety and alarm equipment is not simultaneously used, existing warranties shall be voided, and the
manufacturer disclaims any liability whatsoever for any loss, personal injury or damage.
General Safety
• Read all manuals included with this product carefully. Be thoroughly familiar with the controls and the proper
use of the equipment.
• Follow all local electrical and safety codes as well as the United States National Electrical Codes (NEC) and
Occupational Safety and Health Act (OSHA).
• Only persons well acquainted with these rules of safe operation should be allowed to use the compressor.
• Keep visitors away and NEVER allow children in the work area.
• Wear safety glasses and use hearing protection when operating the unit.
• Do not stand on or use the unit as a handhold.
• Before each use, inspect compressed air system and electrical components for signs of damage,
deterioration, weakness or leakage. Repair or replace defective items before using.
• Check all fasteners at frequent intervals for proper tightness.
Motors, electrical equipment and controls can cause electrical arcs that 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.
• 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.
• Keep fingers away from a running compressor; fast moving and hot parts will cause injury and/or burns.
• 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.
• To reduce fire hazard, keep engine/motor exterior free of oil, solvent, or excessive grease.
An ASME code safety relief valve with a setting no higher than the Maximum
Allowable Working Pressure (MAWP) of the tank 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 safety valve in the intercooler does not provide system protection.
Maximum operating pressure is 175 psi for two-stage compressors. Do not
operate with pressure switch or pilot valves set higher than 175 psi (two-stage).

INSTALLATION INSTRUCTIONS
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.
Picking the Location
Install and operate unit at least 24 inches 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.
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 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 temperature generated and retain the pressure. All
pressurized components of the air system must have a pressure
rating of 200 psi or higher. 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.

INSTALLATION INSTRUCTIONS (CONTINUED)
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
familiar with induction motor controls. 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. Refer to
motor name plate for electrical ratings and specifications.
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.
Minimum Wire Size (Use 75°C Copper Wire)
Make sure voltage is correct with the motor wiring.
NOTE: If using 208 volts single phase, make sure the motor name plate states it is rated
for 208 volts single phase. 230 volt single phase motors do not work on 208 volts unless
they have the 208 volt rating.
Single Phase Three Phase
HP Amps 230V 208/230V 460/575V
SPL up to 22.0 10 AWG
5.0 8 AWG 12 AWG 14 AWG

10.0 N/A 8 AWG 12 AWG
15.0 N/A 6 AWG 10 AWG
25.0 N/A 3 AWG 8 AWG
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.

INSTALLATION INSTRUCTIONS (CONTINUED)
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.
Breakers and Fuses
The entire electrical system should be checked by a
certified electrician. Time delay breakers and fuses are
required for this compressor. A tripped breaker or blown
fuses may indicate a direct short to ground, high current
draw, improper wiring, incorrect fuse or breaker size
and/or type. This needs to be evaluated by a certified
electrician.
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 5 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 6 wiring diagram.

Direction of Rotation
NOTE: Improper rotation will result in reduced compressor
life.
The direction of rotation must be counterclockwise (as
shown by the arrow on the flywheel in Figure 7) 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.
Lubrication
This unit contains no oil.
Before operating compressor, fill
to the center of the sight gauge (see Figure 8).
Using any other type of oil may
shorten pump life and damage
valves.
Recommended Oil (2 Options)
Single viscosity SAE 30 ISO100 nondetergent
compressor oil. Part number ST125303AV (0.5 qt) or
ST126701AV (4 qt).
10W30 synthetic oil such as Mobil 1®or CE0032 (1 qt).
Oil Capacity
Approximately 0.5 quarts
Fill the pump with oil to the center of the sight gauge
using oil fill opening (see Figure 8). Do NOT fill the
pump through the breather cap opening as this may
cause oil to leak and spray out during operation.
NOTE: Some residual oil may still be in the pump from
factory testing leaving a thin coat on the sight gauge;
however, there is not enough oil to operate the unit.

OPERATING INSTRUCTIONS
IMPORTANT: Check motor rotation before operating the compressor.
All lubricated compressor pumps discharge 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.
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.
2. Turn off the compressor and close drain cock. The compressor is now ready for use.
Pressure Switch, Start - Stop
NOTE: This compressor has a maximum operating pressure of
175 PSI for two-stage 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 9).
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.
Draining Tank
Condensation must be drained from the tank daily.
Duty Cycle
Each pump on this compressor is designed to operate up to 75% of the time. Long-term or on-time operation
over 75% could decrease the life of the pump and motor.

MAINTENANCE AND INSPECTION INSTRUCTIONS
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 10). 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 tamper with the ASME safety valve.
Tank
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.
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 Installation. Add oil as required. The oil should be changed every three months or after every 500 hours of
operation; whichever comes first.
If the compressor is running 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 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.
Air Filter
Never run the compressor pump without an intake air filter or with
a clogged intake air filter. The air filter element should be checked
monthly (see Figure 11). Operating compressor with a dirty filter can
cause high oil consumption and increase oil contamination in the
discharge air. If the air filter is dirty it must be replaced.

MAINTENANCE AND INSPECTION INSTRUCTIONS (CONTINUED)
Intercooler
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. Clean all dirt, dust and other
accumulations from the intercooler fins.
Components
Turn off all power and clean the 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 inch to 1/2 inch deflection with normal thumb
pressure. Also, align belts using a straight edge against the face of the flywheel and touching the rim on both
sides of the face. The belts should be parallel to this straight edge (see Figure 12). Dimension A should be the
