canopy/doors are closed during operation.
The specification of this machine is such that the machine is not
suitable for use in flammable gas risk areas.
Installation of this compressor must be in accordance with
recognized electrical codes and any local Health and Safety Codes.
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 oils. Metal bowls should be used on a
pressurized system.
Compressed air
Compressed air can be dangerous if incorrectly handled. Before
doing any work on the unit, ensure that all pressure is vented from the
system and that the machine cannot be started accidentally.
Ensure that the machine is operating at the rated pressure and that
the rated pressure is known to all relevant personnel.
All air pressure equipment installed in or connected to the machine
must have safe working pressure ratings of at least the machine rated
pressure.
If more than one compressor is connected to one common
downstream plant, effective isolation valves must be fitted and
controlled by work procedures, so that one machine cannot accidently
be pressurized / over pressurized by another.
Compressed air must not be used for a direct feed to any form of
breathing apparatus or mask.
The discharged air contains a very small percentage of compressor
lubricating oil and care should be taken to ensure that downstream
equipment is compatible.
If the discharged air is to be ultimately released into a confined
space, adequate ventilation must be provided.
When using compressed air always use appropriate personal
protective equipment.
All pressure containing parts, especially flexible hoses and their
couplings, must be regularly inspected, be free from defects and be
replaced according to the Manual instructions.
Compressed air can be dangerous if incorrectly handled. Before
doing any work on the unit, ensure that all pressure is vented from the
system and that the machine cannot be started accidentally.
Avoid bodily contact with compressed air.
All safety valves located in the separator tank must be checked
periodically for correct operation.
Do not over–pressurize the receiver tank or similar vessels beyond
design limits.
Do not use a receiver tank or similar vessels that fail to meet the
design requirements of the compressor. Contact your distributor for
assistance.
Do not drill into, weld or otherwise alter the receiver tank or similar
vessels.
Do not remove, adjust, change, modify or make substitutions for
safety/relief valves, pressure switches or other pressure control
related devices.

LOCATION IN THE PLANT
WARNING FOR COMPRESSORS EQUIPPED WITH ELECTRIC
DRAIN VALVE
WARNING
The electric drain valve incorporates arcing or 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.
Consult local officials for information regarding acceptable noise
levels in your area. Enclosed compressors are available for low noise
applications.
The compressor must be permanently mounted to a firm, level floor
capable of supporting it. Ensure that the compressor is positioned
securely and on a stable foundation. Any risk of movement should be
removed by suitable means, especially to avoid strain on any rigid
discharge piping.
WARNING
Remove the compressor from the skid before mounting.
When mounting the compressor, install bolts through the mounting
feet and into the mounting surface. Do not bolt uneven feet tightly to the
foundation, as this will cause excessive stress on the receiver tank.
Use metal shims to level the compressor if necessary.

CAUTION
Never operate in temperatures below 20_F (–6.6_C) or above
104_F (40_C).
REMOTE AIR INLET PIPING
If the air around the compressor 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.
CAUTION
Do not operate the compressor without the air inlet filter(s).
DISCHARGE PIPING
If it is necessary to install air discharge and condensate discharge
piping, adhere to the following guidelines. Contact your dealer for more
information.
WARNING
Do not use plastic pipe, soldered copper fittings, rubber hose, or
lead–tin soldered joints anywhere in the compressed air system.
WARNING
If an aftercooler, check valve, block valve, or any other restriction
is added to the compressor discharge, install a properly sized coded
safety/relief valve between the compressor discharge and restriction.
CAUTION
If you will be using the “All Season Select” synthetic compressor
lubricant, all downstream piping material and system components must
be compatible. Refer to the material compatibility list. If there are
incompatible materials present in your system, or if there are materials
not included in the list, contact your dealer.

COMPRESSOR LUBRICATION
A. Oil fill plug
B. Low oil level switch
C. Oil drain plug
CAUTION
Do not operate without lubricant or with inadequate lubricant.
Ingersoll–Rand is not responsible for compressor failure caused by
inadequate lubrication.
We recommend ALL SEASON SELECT synthetic compressor
lubricant.
You may use a petroleum–based lubricant that is premium quality,
does not contain detergents, contains only anti–rust, anti–oxidation,
and anti–foam agents as additives, has a flashpoint of 440_F (227_C)
or higher, and has an auto–ignition point of 650_F (343_C) or higher.
See the petroleum lubricant viscosity table below. The table is
intended as a general guide only. Heavy–duty operating conditions
require heavier oil viscosity. Refer specific operating conditions to your
dealer for recommendations.
Temperature Around Compressor Viscosity @ 37.8_C(100_F ) Viscosity Grade

80 – 104 26.7 – 40 750 165 150 40
NOTE
If you use a petroleum–based compressor lubricant at start–up and
decide to convert to ALL SEASON SELECT lubricant later, the
compressor valves must be thoroughly decarbonized and the
crankcase must be flushed before conversion.
Filling Procedures:
1. For enclosed compressors, remove the front panel.
2. Unscrew and remove the oil fill plug.
CAUTION
Do not remove the oil fill plug while the compressor is running.
3. Slowly fill the crankcase with lubricant until the lubricant reaches the
top thread of the oil fill opening and the top of the sight glass.

4. Replace the oil fill plug HAND TIGHT ONLY.
LOW OIL LEVEL SWITCH
A float activated low oil level switch may be installed to protect your
unit against damage due to insufficient compressor level oil. Low oil
level in the compressor crankcase causes the switch contacts to close,
thus energizing the shunt coil in the combination pressure switch. This
in turn shuts the pressure switch off. Once proper oil level has been
restored the pressure switch (control panel) lever needs to be turned
to Auto to start the unit.
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 (0.946L) 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.
NOTE
On enclosed compressors, the front panel must be removed to
access the low oil level switch.

2. Open the service valve fully to prevent air pressure from building in
the tank.
3. Move the pressure switch lever or control panel knob to
”ON/AUTO”. The unit will start.
CAUTION
Unusual noise or vibration indicates a problem. Do not continue to
operate until you identify and correct the source of the problem.
NOTE
Ensure the direction of rotation is correct per the arrow on the motor
or arrow on the blower housing on enclosed units. If the rotation is
incorrect on three–phase units, interchange any two of the three leads.
4 Run the unit for 30 minutes. Ensure the service valve is fully open
and there is no tank pressure build up.
5. After 30 minutes, close the service valve fully. The air receiver will
fill to cut–out pressure and the motor will stop. The unit is now ready for
use.
NORMAL START–UP
1. Set the pressure switch lever or control panel knob to ”OFF”.
2. Close the service valve.
3. Attach hose and accessory.
4. Move the pressure switch lever or control panel knob to
”ON/AUTO”. The unit will start.
5. Allow tank pressure to build. The motor will stop when tank pressure
reaches cut–out pressure.
6. Open the service valve. The unit is now ready for use.
NOTE
When the receiver tank pressure drops below the factory pre–set
minimum, the pressure switch resets and restarts the unit.
When you are finished:
1. Set the pressure switch lever or control panel knob to ”OFF”.
2. Close the service valve fully.
3. Remove the air tool or accessory.
4. Slowly open the service valve to vent air pressure down to 20 psig.

COMPRESSOR CONTROLS
Direct online starting:
The compressor is equipped for Automatic Start & Stop Control.
When the receiver tank pressure reaches the factory pre–set
maximum pressure, the pressure switch stops the unit. When the
receiver tank pressure drops below the factory pre–set minimum. The
pressure switch resets and restarts the unit.
The combination pressure switch and starter performs the dual
function of a direct online starter and a pressure switch. On enclosed
units the combination pressure switch is behind the control panel. It can
be accessed by removing the front panel and then unscrewing the four
screws holding the control panel. The pressure switch cover can be
removed by unscrewing the two screws holding the cover.
Pressure switch adjustment:
The compressor package will cut–in and cut–out at factory preset
pressure settings. Adjust the pressure switch only if absolutely
necessary.
Adjustments are to be carried out only when the switch is mounted,
under pressure and voltage–free.
WARNING
High voltage is present at the pressure switch contacts when the
power supply is connected. Disconnect, lock and tag main power
supply before making adjustments.
CAUTION
Do not adjust the pressure switch to exceed the maximum
discharge pressure of the unit.
NOTE
When replacing the pressure switch cover, ensure the selector
knob on the cover and the lever on the switch are both in the ”OFF” posi-
tion.
