NOTICE
WARNING
COMPRESSED AIR AND ELECTRICITY
ARE DANGEROUS.
BEFORE DOING ANY WORK ON THIS
UNIT,BE SURE THE ELECTRICAL SUPPLY
HAS BEEN CUT OFF–LOCKED & TAGGED
AND THE ENTIRE COMPRESSOR SYSTEM
HAS BEEN VENTED OF ALL PRESSURE.
1. Do not remove the covers, loosen or
remove any fittings, connections or
devices when this unit is in operation. Hot
liquid and air under pressure that are
contained within this unit can cause
severe injury or death.
2. The compressor has high and
dangerous voltage in the motor starter and
control box. All installations must be in
accordance with recognized electrical
codes. Before working on the electrical
system, be sure to remove voltage from
the system by use of a manualdisconnect-switch. A circuit breaker or
fuse safety switch must be provided in the
electrical supply line leading to the
compressor.
Those responsible for installation of this
equipment must provide suitable grounds,
maintenance clearance and lightning
arrestors for all electrical components as
stipulated in O.S.H.A. 1910.308 through
1910.329.
3. Do not operate the compressor at higher
discharge pressure than those specified
on the Compressor Nameplate or motor
overload will occur. This condition will
result in compressor motor shutdown.
4. Use only safety solvent for cleaning the
compressor and auxiliary equipment.
5. Install a manual shut off valve (isolation
type) in the discharge line. When a safety
valve is installed between the isolation
valve and the compressor, it must have
sufficient capacity to relieve the full
capacity of the compressor(s).
6. Whenever pressure is released through
the pressure relief valve, it is due to
excessive pressure in the system. The
cause for the excessive pressure should
be investigated immediately.
7. Before doing any mechanical work on
the compressor:
a.) Shut the unit down.
b.) Electrically isolate the compressor by
use of the manual disconnect switch in the
power line to the unit. Lock and tag the
switch so that it cannot be operated.
c.) Vent pressure from the compressor and
isolate the unit from any other source of
air.
8. There can be adverse effects if
compressor lubricants are allowed to enter
plant air systems.
Air line separators, properly selected and
installed, will minimize any liquid carryover.
The use of plastic bowls on line filters
without metal guards can be hazardous.
From a safety standpoint, metal bowls
should be used on any pressurized
system. Review of your plant air line
system is recommended.
9. When a receiver is installed, it is
recommended that occupational safety
and health standards as covered in the
Federal Register, Volume 36, number 105,
part 11, paragraph 1910.169 be adhered to
in the installation and maintenance of this
receiver.
10. Before starting the compressor, its
maintenance instructions should be
thoroughly read and understood.
11. After maintenance functions are
completed, covers and guards must be
replaced.
0.2 SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
BEFORE PROCEEDING, READ CAREFULLY BEFORE INSTALLING THE
COMPRESSOR OR PERFORMING ANY MAINTENANCE
4
WARNING
Failure to adhere to these recommendations can result in mechanical failure, property damage and serious injur y or death.
All air and water inlet, and air and water discharge pipework to and from the inlet and discharge port connections must take
into account vibration, pulsations, temperature, maximum pressure applied, corrosion and chemical resistance. In addition, it
should be noted that lubricated compressors will discharge some oil into the air stream; therefore, compatibility between
discharge piping, system accessories and software must be assured.
For the foregoing reasons, the use of plastic piping, soldered copper fittings and rubber hose as discharge piping is not
recommended. In addition, flexible joints and/or flex lines can only be considered for such purposes if their specifications fit
the operating parameters of the system.
It is the responsibility of the installer and owner to provide the appropriate service pipework to and from the machine.
WARNING
CHECK HIGH AIR TEMPERATURE
There is a high discharge air temperature shutdown function built into the Intellisys on each compressor. It is factory pre-set
at 228°F (109°C).This function should be checked at regular intervals for proper operation, once a month is recommended.
The procedure is:
1. Block off the cooling air discharge.
2. The compressor discharge temperature will rise at a rapid rate.Shutdown should occur when the discharge
temperature reaches the pre-set maximum discharge air temperature setting of the Intellisys.The display should
indicate “HIGH AIREND DISCH TEMP” and flash “ALARM”.
The actual temperature at which shutdown occurs should be recorded for comparison to the Intellisys set point and with
similar future test results.

1.0 RECEIPT OF EQUIPMENT
1.1 INSPECTION
When you receive the compressor please inspect it
closely. Any indication of careless handling by the carrier
should be noted on the delivery receipt especially if the
compressor will not be immediately uncrated. Obtaining
the delivery man’s signed agreement to any noted
damages will facilitate any future insurance claims.
1.2 UNPACKING AND HANDLING
The compressor package has been mounted on a base
which provides for forklifting between the two side
channels to facilitate handling during shipment. Care in
positioning the forklifts is important because the location
of the center of gravity is strongly affected by the location
of the compression module and drive motor.
Slings can be used to lift the crates, but spreader bars
must be used to prevent the slings from exerting a force
against the sides of the crates.
1.3 TOOLS
Remove compressor unit from wooden skid.A crowbar
and hammer will be needed.

2.0 INSTALLATION
2.1 VENTILA TION
Oil flooded rotary air compressors produce large
amounts of heat. Because of this large heat production,
the compressor must be placed in a room with adequate
ventilation.
If heated air from the compressor exhaust is allowed to
recirculate back to the compressor, the compressor will
overheat and shut down.This heat must be exhausted
from the room.You should take this into consideration
when you decide where to place the compressor within
your plant. Consider that the required maintenance
clearance is 3 ft (.9 m) all around the compressor.
However 42” (1.06m), or minimum required by latest NEC
or applicable local codes, must be maintained in front of
control panel.
Ambient temperatures higher than 115°F (46°C)
should be avoided as well as areas of high humidity.
Consider also the environment surrounding or near
the compressor.The area selected for the location of
the compressor should be free of dust, chemicals,
metal filings, paint fumes and overspray.
2.2 FOUNDATION REQUIREMENTS
Refer to the foundation plan for the particular model
compressor to be installed. See Section 8.0.
The compressor can be installed on any level floor that is
capable of supporting it. Compressor weights are listed
on the foundation plans.
When sound transmission is of particular impor tance it is
often helpful to install a sheet of rubber-fabric-matting, or
cork under the compressor to reduce the possibility of
resonant sounds being transmitted or amplified through
the floor.
2.3 PIPING
The use of plastic bowls on line filters without metal
guards can be hazardous.Their safety can be affected by
either synthetic lubricants or the additives used in mineral
oil. From a safety standpoint, metal bowls should be used
on any pressurized system. Review of your plant air line
system is recommended.
The built-in aftercooler reduces the discharge air
temperature well below the dew point (for most ambient
conditions), therefore, considerable water vapor is
condensed.To remove this condensation, each
compressor with built-in aftercooler is furnished with a
combination condensate separator/trap.

DISCHARGE PIPING WITH AFTERCOOLER
ROTARY-RECIP IN PARALLEL
Do not use the compressor
to support the discharge pipe.
Careful review of piping size from the compressor
connection point is essential. Length of pipe, size of pipe,
number and type of fittings and valves must be
considered for optimum efficiency of your compressor.
It is essential when installing a new compressor to review
the total plant air system.This is to ensure a safe and
effective total system.
Liquid water occurs naturally in air lines as a result of
compression. Moisture vapor in ambient air is
concentrated when pressurized and condenses when
cooled in downstream air piping.
Moisture in compressed air is responsible for costly
problems in almost every application that relies on
compressed air.Some common problems caused by
moisture are rusting and scaling in pipelines, clogging of
instruments, sticking of control valves, and freezing of
outdoor compressed air lines. Any of these could result in
partial or total plant shutdown.
Compressed air dryers reduce the water vapor concentration and prevent liquid water formation in
compressed air lines. Dryers are a necessary companion
to filters, aftercoolers, and automatic drains for improving
the productivity of compressed air systems.
NOTICE
2.3 PIPING (Continued)
A dripleg assembly and isolation valve should be
mounted near the compressor discharge. A drain line
should be connected to the condensate drain in the
base.
IMPORTANT :The drain line must slope downward from
the base to work properly.
NOTE: For ease of inspection of the automatic drain trap
operation, the drain piping should include an open funnel.
It is possible that additional condensation can occur if the
downstream piping cools the air even further and low
points in the piping systems should be provided with
driplegs and traps.
IMPORTANT :Discharge piping should be at least as
large as the discharge connection at the compressor

Before proceeding further, we recommend that you
review the safety data in the front of this manual.
Locate the compressor data plate on the side of the
cooler box or end of the unit.
The data plate lists the rated operating pressure, the
maximum discharge pressure and the electric motor
characteristics and power.
Confirm that the line voltage and compressor nameplate
voltage are the same and that the standard starter box
meets the intent of NEMA 1 guidelines.
Open the starter box door.Confirm that all electrical
connections are made and tightened. Confirm that the
control transformer is wired correctly for supply voltage.
See Figure 2.4-1 on next page for typical control
transformer wiring.
Two types of dr yers, refrigerated or desiccant, are used
to correct moisture related problems in a compressed air
system. Refrigerated dryers are normally specified where
compressed air pressure dew points of 33°F (1°C) to
39°F (4°C) are adequate. Desiccant dryers are required
where pressure dew points must be below 33°F (1°C).
Contact your local Ingersoll-Rand distributor for
assistance in selecting correct Ingersoll-Rand filtration or
drying products.
NOTE: Screw type compressors should not be installed
in air systems with reciprocating compressors without a
means of pulsation isolation, such as a common receiver
tank.We recommend both types of compressor units be
piped to a common receiver utilizing individual air lines.
When two rotary units are operated in parallel, provide an
isolation valve and drain trap for each compressor before
the common receiver.

2.5 OUTDOOR SHELTERED INSTALLATION
Many times a compressor must be installed outside due
to jobsite conditions or limited space within a
manufacturing facility. When this occurs there are certain
items that should be incorporated into the installation to
help ensure trouble free operation.These items have
been listed below plus Figure 2.5-1 has been included to
show a typical outdoor sheltered installation.The unit
must be purchased with the Outdoor Modification Option
to provide NEMA 4 electrics and a cabinet exhaust on
the end of the unit rather than the top to prevent recirculation of cooling air.
■ The compressor should be on a concrete pad
designed to drain water away.If the concrete pad is
sloped, then the compressor must be leveled.In order
to properly pull cooling air through the aftercooler, the
base/skid must be sealed to the concrete pad.
■ The roof of the shelter should extend a minimum of
4 ft (1.2 m) around all sides of the compressor to prevent direct rain and snow from falling on the unit.
■ Air-cooled machines must be arranged under the
shelter in a way that prevents air recirculation (i.e.hot
exhaust back to the package inlet).
■ If the installation includes more than one compressor,
the hot air exhaust should not be directed towards the
fresh air intake of the second unit or an Air Dryer.
■ If a standard machine is to be installed outside, the
ambient temperature must never drop below 35°F
(1.7°C).
■ If ambient temperature drops below 35°F (1.7°C) to as
low as –10°F (–23°C) the unit must be supplied with
the Low Ambient Option. Installations below –10°F
(–23°C) ambient are not recommended.The Low
Ambient Option requires a separate power source to
operate internal heaters.
■ Arrange the machine with the Intellisys con-
troller/starter enclosure facing away from the sun as
radiant heat can affect starter/lntellisys performance.
Also direct sunlight and UV rays will degrade the
membrane touch panel.This is not a warrantable
situation.
■ Power disconnect switch should be within line of sight
and in close proximity to the unit.N.E.C.and local
electrical codes must be followed when installing the
power disconnect switch.
■ Condensate drains must never be allowed to dump on
the ground. Run to a suitable sump for future
collection and disposal or separation of lubricant and
water mixture.
■ Incoming power connections must use suitable
connectors for outdoor weather tight service.
■ A minimum of 3 ft (.9 m) clearance must be allowed
on all four sides of the unit for service access.If
possible, access by a forklift and/or an overhead beam
hoist should be kept in mind (for eventual service to
airend or motor).
■ If the area around the installation contains fine
airborne dust or lint and fibers etc., then the unit
should be purchased with the High Dust Filter Option
and TEFC motors.
■ If larger debris, such as leaves or trash, are blowing in
the area, the Inlet Panel Filter Accessory should be
purchased and added to the unit (ship loose item).
■ Some type of protection such as a fence or security
system, should be provided to prevent unauthorized
access.

start and load if there is sufficient demand for air.
STOP
Pressing this button will activate the unloaded stop
sequence. If the compressor is running loaded, it will
unload and continue to run unloaded for an adjustable
10 to 30 seconds and then stop.If the compressor is
running unloaded, it will stop immediately.
UNLOAD
Pressing this button will cause the compressor to
unload and remain unloaded.The display will indicate
the machine is “Running Unloaded”, and “Mode:
UNLOAD”.
LOAD
Pressing this button will cause the compressor to load
if the compressor is running and if the “Discharge
Pressure” is less than the “Online Pressure”. This also
returns the machine to the operating mode that is
specified by the “Mode of Operation”set point.
The other five buttons provide access to various
operator-selectable functions and machine operating
conditions.The pur pose of each of these buttons is
defined by the display screen and the particular
function being performed at that time.
ARROWS
These up and down buttons have multiple functions
relating to the right half of the display screen.When
lists are presented, the buttons are used to move up or
down through the items on the list.The small arrow(s)
displayed in the upper right corner of the display
screen indicate when you can move up (designated by
arrow head pointing up) and/or down (designated by

discharge pressure has not started rising at the end of
this time period, the lead compressor will load the next
compressor in the sequencer.
3.10.5 Lead Change - Hours- This is the number of
hours the compressor will operate as the lead unit.
Once a compressor has operated as the lead for this
number of hours, it will transfer the lead to the next
compressor in the sequence.This setpoint does not
apply to a unit where the lead compressor is set to
always or never. If this setpoint is set to 0, the next 2
setpoints will determine when the lead is transferred.
3.10.6 Lead Change - Day & Lead Change - Time-
These two setpoints are used together.If the Lead
Change - Hours setpoint is set to 0, these two
setpoints will be used to determine when the
compressor will transfer the lead to the next
compressor in sequence. Lead Change - Day is the
day of the week that the compressor will transfer the
lead. Lead Change - Time is the time of the day that
the compressor will transfer the lead.

Pressing the WARNING button will return the display
to the WARNING screen and the RESET button.
A Warning needs to be reset by the operator by
pressing the RESET button twice.
The possible Warning messages are as follows.
AIREND DISCHARGE TEMP- This will occur if the
Airend Discharge (2ATT) exceeds 97% of the alarm
limit, 228°F (109°C), and is not adjustable.
CHANGE COOLANT FILTER- This warning will occur
if the high side pressure is 20 psig (1.4 bar) greater
than the low side pressure of 1 DPS, and the Injected
Coolant temperature (2CTT) is greater than
120°F (49°C).
CHANGE INLET FILTER- This will occur if the Inlet
Vacuum (1AVPT) is greater than 0.7 psig (.05 bar) and
the machine is fully loaded (inlet valve is completely
open).
CHANGE SEPR ELEMENT- This warning will occur if
the pressure on the Separator (3APT) is 12 psig
(.8 bar) greater than the pressure at the Package
Discharge (4APT), and the machine is fully loaded.
When a Warning occurs, a question mark will flash on
the display screen and appear in large letters as
shown above.The display message will indicate what
caused the warning.
If multiple Warnings exist, the small up/down arrows
will appear in the upper right corner of the display
screen.The multiple Warnings can be seen by
pressing the up and down arrow buttons.Pressing the
STATUS button will display the CURRENT STATUS
screen with the WARNING button indicating a Warning
still exists.
?
HIGH DISCHARGE PRESS- This can occur if the
machine’s loading function is being controlled by a host
device, such as a sequencer or an lSC.This warning
will occur when the package discharge pressure is
above the maximum offline pressure (rated pressure
plus 3 psig [.2 bar]) for more than 3 seconds.This
warning will cause the compressor to unload.The host
device will not be able to load the compressor until the
package discharge pressure falls to the rated pressure
of the machine.
SENSOR FAILURE 4ATT- This will occur if the
Package Discharge Temperature Sensor (4ATT) is
recognized as missing or broken.
AUXILIARY 1 (OR 2) - This warning will occur if either
of the auxiliary contacts closes.
HIGH SUMP/LINE DIF - This warning will occur if the
compressor is running loaded, the injected coolant
temperature is greater than or equal to 120 deg. F,
(49°C) the package discharge pressure is greater than
90 psig, (6.3 bar) the sump pressure is greater than the
compressor’s rated pressure, and the sump pressure is
25 psig (1.8 bar) or more above the package discharge
pressure.
