Notes
Pressurized air from the system may cause personnel injury or property damage if the unit is improp-
erly operated or maintained. The operator should have carefully read and become familiar with the
contents of this manual before installing, wiring, starting, operating, adjusting and maintaining the
system. The operator is expected to use common sense safety precautions, good workmanship
practices and follow any related local safety precautions.
In addition:
• Before starting any installation or maintenance procedures, disconnect all power to the
package.
• All electrical procedures must be in compliance with all national, state and local codes and re-
quirements.
• A certified electrician should connect all wiring.
• Refer to the electrical wiring diagram provided with the unit before starting any installation or
maintenance work.
• Release all pressure from the package before removing, loosening, or servicing any covers,
guards, fittings, connections, or other devices.
• Notify appropriate facility personnel if repairs or maintenance will affect available compressed air
levels.
• This is a high speed, rotating piece of machinery. Do not attempt to service any part while ma-
chine is in operation.
• Do not operate unit without belt guards, shields or screens in place.
• Make sure that all loose articles, packing material, and tools are clear of the package.
• Check all safety devices periodically for proper operation.
• Never operate a compressor with its relief valve not in place. Damage to the compressor may oc-
cur.
• Electrical service must be the same as specified on the control panel nameplate or damage to
the equipment may occur.
• Vibration during shipment can loosen electrical terminals, fuse inserts, and mechanical connec-
tions. Tighten as necessary.
System Configurations
The Reciprocating Air systems are tank mounted units. All consist of at least one compressor, one
motor, integral pre-wired control panel and air receiver. The complete package is pre-wired, pre-
piped, and assembled.
Compressor Module
The compressor is a continuous duty rated lubricated reciprocating type. The design is two stage
and air cooled with finger type stainless steel valves. An oil splasher is fitted to the connecting rod to
lubricate all moving parts. The connecting rod and crankcase assembly is precision machined and
dynamically balanced. The crankshaft is forged out of carbon steel, hardened, and precision ground.
The crankshaft is provided with steel roller bearings and phosphor bronze bushings. The crankcase
is made of high grade cast iron. It acts as sump for the lubricating oil and is provided with a breather
drain plug and dipstick. The breather maintains a partial vacuum in the crankcase to facilitate better
breathing. The cylinders and cylinder heads are made of high grade cast iron and they have close
deep fins for effective cooling. The hardness of the cylinders is closely controlled to insure high wear
resistance. The pistons are automotive type made out of low expansion aluminum alloy. They are
provide with plain compression rings, stepped compression rings and slotted oil control rings. The
rings are made of special quality close grained cast iron and designed for controlling wear and keep-
ing oil consumption at a minimum. The wrist pins are made of chrome steel case hardened and pre-
cision ground. The intercooler is made of aluminum with fins for effective cooling.
Intake Filter
Each compressor is fitted with inlet air filters. The inlet filter removes dust from the incoming air
through an element.
Control System The mounted and wired control system is NEMA 1 and U.L. labeled. The . The
control panel also includes full voltage motor starters with overload protection, Off-On selector
switch and a pressure switch.
Air Receiver
The air receiver is ASME Coded, National Board Certified, and rated for a minimum 200 PSIG de-
sign pressure. The tank will include a safety relief valve, pressure gauge and manual drain valve.
2.2 Handling
!!WARNING!!
USE APPROPRIATE LOAD RATED LIFTING EQUIPMENT AND OBSERVE SAFE LIFTING PRO-
CEDURES DURING ALL MOVES.
The compressor package can be moved with either a forklift or dollies. Keep all packing in place dur-
ing installation to minimize damage. Examine the route the unit must travel and note dimensions of
doorways and low ceilings. Units should be placed to ensure easy access to perform maintenance
and high visibility of indicators and gauges.
2.3 Location
The Air system should be installed indoors in a clean, well-ventilated environment. Areas of exces-
sive dust, dirt or other air-borne particulate should be avoided. Secure the package to a flat, level
surface capable of supporting the weight and forces of the unit. Make sure that the main base is not
bowed, twisted, or uneven. The tank must be securely bolted using all mounting holes provided in
the tank. If a raised concrete pad is used, the tank must not overhang the concrete pad. A method to
drain away moisture is necessary. If a gravity drain is not available, a connection to a drain is neces-
sary. The area should have a maximum ambient temperature of 113 oF (45oC). (Note: At tempera-
tures below 32oF condensate can occur which could affect operation.)
2.5 Wiring
WARNING!
BE SURE TO DISCONNECT ALL ELECTRICAL POWER TO THE COMPRESSOR SYSTEM BE-
FORE PERFORMING ANY ELECTRICAL PROCEDURES.
Refer to the electrical diagram provided with the unit before starting any installation or
maintenance work. Do not operate compressor on a voltage other than the voltage specified
on the compressor nameplate. All customer wiring should be in compliance with the National
Electrical Code and any other applicable state or local codes.
Check the control voltage, phase, and amp ratings before starting the electrical installation, and
make sure the voltage supplied by the customer is the same.
The wire size should be able to handle peak motor amp load of all operating units, refer to the full
load and compressor system amperes on the wiring diagram.
Check all electrical connections within the air system that may have loosened during shipment.
Only qualified electricians should make power connections to the control panel and any intercon-
necting wiring.
If emergency generator is used for backup make sure the electrical supply is consistent with the air
system’s requirements.
If equipped with an emergency generator the three-phase power supplied must match that of the
normal supply to allow for correct direction of the motor rotation at all times.
If equipped with an emergency generator the three-phase power supplied must match that of the
normal supply to allow for correct direction of the motor rotation at all times.

Check for correct direction of rotation of compressor by momentarily turning the Off-On switch to the
“On” position and observing rotation.
WARNING:
DO NOT RUN THE COMPRESSOR BACKWARDS!
Rotation direction arrows are located on the belt guard (rotation is clockwise, facing the compressor
pulley). Correct the rotation, if required, by switching the motor leads at the starter.
Start compressor by turning the “Off-On” switch to the “On” position. Allow compressor to operate for
a short time (15 to 30 seconds) and check for any unusual noises or vibrations.
If everything appears normal, allow compressor to run in the “On” mode until pressure builds in the
air receiver. The compressor should stop when the pressure reading reaches 125 psig. Check for
any leaks in the piping. Repair leaks, if needed.
