NOTES
Notes are used for supplementary information.
BREATHING AIR PRECAUTION
Ingersoll Rand air compressors are not designed, intended or
approved for breathing air. Compressed air should not be used for
breathing air applications unless treated in accordance with all
applicable codes and regulations.
General Information
Ensure that the operator reads and understands the decals and
consults the manuals before maintenance or operation.
Ensure that the Operation and Maintenance manual is not removed
permanently from the machine.
Ensure that maintenance personnel are adequately trained,
competent and have read the Maintenance Manuals.
Do not point air nozzles or sprayers toward anyone.
Compressed air and electricity can be dangerous. Before
undertaking any work on the compressor, ensure that the electrical
supply has been isolated and the compressor has been relieved of all
pressure.
Wear eye protection when operating or servicing compressor.
All persons positioned near to operating machinery should be
equipped with hearing protection and given instructions on its use in
accordance with workplace safety legislation.
Make sure that all protective covers are in place and that the
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
recognised electrical codes and any local Health and Safety Codes.
The use of plastic bowls on line filters can be hazardous. Their
safety can be affected by either synthetic lubricants, or the additives
used in mineral oils. Ingersoll Rand recommends that only filters with
metal bowls should be used on a pressurised 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.
WARNING
Imposing a normal or emergency stop on the compressor will
only relieve pressure upstream of the minimum pressure valve on
top of the separator tank.
If maintenance work is required downstream of this valve, ensure
that all pressure is relieved at the process vent point external to
the compressor
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
accidentally be pressurised / over pressurised 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
lubricant 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.
Before servicing the unit, vent pressure before removing the power
to ensure that the gauge reads zero pressure.
Materials
The following substances are used in the manufacture of this
machine and may be hazardous to health if used incorrectly:
. preservative grease
. rust preventative
. compressor coolant
. refridgerant
AVOID INGESTION, SKIN CONTACT AND INHALATION OF
FUMES
Transport
When loading or transporting machines ensure that the specified
lifting and tie down points are used.
Lifting equipment must be properly rated for the weight of the
compressor.
Do not work on or walk under the compressor while it is suspended.
Electrical
Keep all parts of the body and any hand−held tools or other
conductive objects, away from exposed live parts of the electrical
system. Maintain dry footing, stand on insulating surfaces and do not
contact any other portion of the compressor when making adjustments
or repairs to exposed live parts of the electrical system.
WARNING
Any electrical connections or adjustments should only be
made by a suitably qualified electrician
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.
Close and lock all access doors when the compressor is left
unattended.
Do not use extinguishers intended for Class A or Class B fires on
electrical fires. Use only extinguishers suitable for class BC or class
ABC fires.
Attempt repairs only in clean, dry, well lighted and ventilated areas.
Connect the compressor only to electrical systems that are
compatible with its electrical characteristics and that are within it’s rated
capacity.
Condensate disposal
As waste water regulations vary by country and region it is the
responsibility of the user to establish the limitations and regulations in
their particular area. Ingersoll Rand and its associated distributors are
happy to advise and assist in these matters.

NOTES
1 Foundation or floor must be level, and support all feet equally. If
necessary, shim or grout the fourth foot.
2 Foundation bolts should project thru nuts a minimum of 13mm
[0.50”] to allow for levelling.
3 Allow a minimum clearance of 1100mm [42”] on the front and
920mm [36”] on the top, left, right and the rear of the package for proper
air circulation and serviceability.
4 Approximate package weight: 475 KG. (1045 LBS)
NOTE
All dimensions are in millimetres (inches) unless otherwise stated.
Ensure that the correct fork lift truck slots or marked lifting points are
used whenever the machine is lifted or transported.
UNPACKING
The compressor will normally be delivered with a polythene cover.
If a knife has to be used to remove this cover ensure that the exterior
paintwork of the compressor is not damaged.
Remove shipping bolts on end panel.
Ensure that all transport and packing materials are discarded in a
manner prescribed by local codes.
DRYER INSTALLATION
Do not connect condensate drains common to other pressurised
drain lines in a closed circuit. Make sure the outflow from the
condensate drains is unimpeded. Connect the condensate piping in
such a way to ensure that sound levels are kept to a minimum during
drainage.
Ensure that all condensate is disposed of in a responsible manner, in
accordance with local norms concerning environmental protection.
The ambient air around the dryer and compressor must not contain
solid or gaseous contaminants. All compressed and condensed gases
can generate acids or chemical products which may damage the
compressor or components inside the dryer.
Take particular care with sulphur, ammonia, chlorine and installations
in marine environments. For further advice or assistance consult your
local Ingersoll Rand representative.

NOTE
Items [2] to [5] are optional or may be existing items of plant. Refer
to your Ingersoll Rand distributor / representative for specific
recommendations.
LOCATION IN THE PLANT
The compressor can be installed on any level floor capable of
supporting it. A dry, well ventilated area where the atmosphere is clean
is recommended. A minimum of 1m (3ft) should be left all around
machine for adequate service access and ventilation.
Adequate clearance needs to be allowed around and above the
machine to permit safe access for specified maintenance tasks.
Ensure that the machine 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.
CAUTION
Screw type compressors [1] should not be installed in air
systems with reciprocating compressors without means of
isolation such as a common receiver tank. It is recommended that
both types of compressor be piped to a common receiver using
individual air lines.
CAUTION
The use of plastic bowls on line filters and other plastic air line
components can be hazardous. Their safety can be affected by
either synthetic coolants or the additives used in mineral oils.
Ingersoll Rand recommends that only filters with metal bowls
should be used on any pressurised system.
CAUTION
The Basic compressor or Total Air System Package, is not
suitable for operation in temperatures liable to cause freezing as
Condensate water is liable to be produced in the after cooler and
receiver where fitted.
Refer to your Ingersoll Rand distributor for further information
DISCHARGE PIPING
Discharge piping should be at least as large as the discharge
connection of the compressor. All piping and fittings should be suitably
rated for the discharge pressure.
It is essential when installing a new compressor [1], to review the
total air system. This is to ensure a safe and effective total system. One
item which should be considered is liquid carryover. Installation of air
dryers [3] is always good practice since properly selected and installed
they can reduce any liquid carryover to zero.
It is good practice to locate an isolation valve close to the
compressor and to install line filters [4].
If you have purchased a TAS model, your compressor package
already includes items [1], [3] and [4].
It is a requirement for air dryers covered under Aircare that correctly
sized Ingersoll Rand pre and afterfilters are installed.

INSTALLATION / HANDLING
27
ELECTRICAL DATA
An independent electrical isolator or disconnect should be installed
adjacent to the compressor.
Feeder cables/wires should be sized by the customer/electrical
contractor to ensure that the circuit is balanced and not overloaded by
other electrical equipment. The length of wiring from a suitable
electrical feed point is critical as voltage drops may impair the
performance of the compressor.
Feeder cables / wires connections to isolator or disconnect should
be tight and clean.
The applied voltage must be compatible with the motor and
compressor data plate ratings.
Do not use a buck and boost transformer.
CAUTION
Never test the insulation resistance of any part of the machines
electrical circuits, including the motor without completely
disconnecting the electronic controller (where fitted).
CAUTION
Do not verify cooling simply by air flow direction, but ensure
that the fan rotates in the correct direction as indicated by
direction arrows
NOTE
If the compressor is installed for 208V 60hz or 380V 60hz
applications, the wiring at the primary of the transformer needs to
be changed during installation.
OUTDOOR MODIFICATION OPTION
EU Directive 2000/14/EC. Noise Emission By Equipment For Use
Outdoors
The standard compressor packages are not suitable for use
outdoors. If the Outdoor Modification Option is fitted to a machine
which will be operated within the EU the machine is not intended to be
used as hire equipment or moved from place to place. It must be
installed as fixed machinery, which is not intended to be moved during
its operational life (For example, a compressor permanently fixed
outside of buildings) and is therefore excluded from the Directive.
This exclusion is on the basis that the machine forms a permanent
part of a factory or plant , and that local Environmental Noise
Regulations will apply to this factory / plant, in place of the directive.

OPERATING INSTRUCTIONS
GENERAL OPERATION
The compressor is an electric motor driven, single stage screw
compressor, complete with accessories piped, wired and baseplate
mounted. It is a totally self contained air compressor package.
The standard compressor is designed to operate in an ambient
range of 35.6_F − 104_F (2_C to 40_C). The maximum temperature
is applicable up to a maximum elevation of 3280ft (1000m) above
sea level. Above this altitude significant reduction in maximum
allowable ambient temperature is required.
Compression in the screw type air compressor is created by the
meshing of two (male & female) helical rotors.
The air/coolant mixture discharges from the compressor into the
separation system. This system removes all but a few PPM of the
coolant from the discharge air. The coolant is returned to the cooling
system and the air passes through the aftercooler and out of the
compressor.
Cooling air is moved through the coolers by the cooling fan and
discharged from the machine.
WARNING
This unit is equipped with automatic cooling fan control. The
package − cooling fan will operate independently of the
compression module. The fan may operate when the
compressor is stopped in automatic restart mode or when the
on−off selector switch is in the ’off’ position with the e−stop
disengaged.
The power transmission from the drive motor to the airend male rotor
is by direct drive.
By cooling the discharge air, much of the water vapour naturally
contained in the air is condensed and may be drained from the
downstream piping and equipment.
The coolant system consists of a sump, cooler, thermostatic valve
and a filter. When the unit is operating, the coolant is pressurized and
forced to the compressor bearings.
The compressor load control system is automatic stop and
restart, with selectable variable speed control. This allows the
compressor to maintain a set discharge line pressure by varying
output capacity to match the system demand. The unit is provided
with an automatic stop and restart system for use in plants where
the air demand varies sufficiently to allow a compressor to shut
down and save power. Significant system volume will assist this and
is recommended.
WARNING
When the unit stops running as the result of low air demand,
it may restart and return to load at any time.
CAUTION
LOW DEMAND APPLICATIONS
During periods of low demand, the compressor may not
reach its normal operating temperature. Sustained operation at
low demand can result in the build up of condensate in the
coolant. If this situation occurs, the lubricating characteristics
of the coolant can be impaired which may lead to damage of the
compressor.
THE COMPRESSOR SHOULD BE ALLOWED AMPLE LOADED
RUNNING TIME.
CAUTION
Cooling air is drawn in at the rear of the machine package
passing through the filter and cooler before being discharged
from the top of the machine. Care should be taken to avoid
blocking the airflow, or causing any restriction in excess of the
maximum backpressure allowed for ducting.
Do not direct the airflow at face or eyes.
Safety of operation is provided as the compressor will shut down if
excessive temperatures or electrical overload conditions should occur.
CAUTION
This unit is not designed or intended to operate when
contaminated with silicone. Lubricants, greases or other items
containing silicone should not be used on this unit.
