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 presure 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
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 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.
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
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 compressor
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 compressor
electrical system.
WARNING
Any electrical connections or adjustments should only be
made by a suitably qualified electrician
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.

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
Note:
Ensure that the unit is wired for proper voltage before installation.
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 6 inches (150mm) should be left at the
rear and 3ft (1m) at the sides of the 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
Before starting machine remove shipping bolt and discard
CAUTION
The standard compressor unit 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].
It is a requirement for air dryers covered under Aircare that correctly
sized Ingersoll Rand pre and afterfilters are installed.

1. If a circuit breaker is selected it should only be a magnetic trip type,
set above the anticipated starting current of the machine, but below the
maximum prospective fault current for the circuit. The circuit breaker
or fuseable disconnect must be capable of breaking the prospective
fault current at its terminals.
2. PVC/PVC Type Calculated using the following conditions:
i) PVC insulated cable, armoured, copper conductors.
ii) Cable clipped to a wall, in free air.
iii) Ambient temperature of 104_F (40_C) and relative humidity of 40%.
iv) 65ft (20m) cable run.
v) Volt drop limited to –10% during starting, –5% during normal
running.
vi) Protected by the circuit breaker listed above.
If there are any deviations from the above, or special regulations
apply, the installation must be planned by a competent, qualified
engineer.
NOTE
All data applies to standard product only.
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.
The control circuit transformer has different voltage tappings.
Ensure that these are set for the specific applied voltage prior to
starting.
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
Ensure that the motor, blower and dryer fan rotate in the
correct direction as indicated by direction arrows, and on
drawing.

OPERATING INSTRUCTIONS – GENERAL
21
SSR UP6 40, SSR UP6 50PE, SSR UP6 50PEI, HF50–PE,
EP50–PE, HP50–PE, HXP50–PE
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 40hp compressor packages are designed to operate in an
ambient range of 35.6_F – 104_F (2_C to 40_C) with a special
option package available to operate in ambient temperatures ranges
from 35.6_F up to 124_F (2_C up to 50_C). The maximum
temperature is applicable to either version up to a maximum
elevation of 3280ft (1000m) above sea level. Above this altitude
significant reduction in maximum allowable ambient temperature is
required.
The 50 hp package is designed for a 115_F (46_C) maximum
ambient.
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.
CAUTION
Cooling air is drawn in at the end 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.
The power transmission from the drive motor to the airend male
rotor is by pulley and belts. The constant auto tensioning system, using
airend mass torque and gas arm, ensures that the belts are always
under the correct tension, eliminating the need for adjustment and
maximizing the life of the belts.
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 on–off line. The
compressor will operate to maintain a set discharge line pressure and
is provided with an auto 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.
With the dryer option, the dryer will run continuously when the
compressor is automatically off line.
WARNING
When the unit stops running as the result of low air demand,
normally indicated by auto restart light, it may restart and return
to load at any time.
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.
