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 .

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.

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.

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 150mm (6 inches) should be left at the
rear and 1m (3ft) 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

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 o f 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.

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.

SSR UP6 15, UP6 20, UP6 25, UP6 30

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.

INSTALLATION / HANDLING

19

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 rotates in the correct direction as indicated b y
direction arrows, and on drawing.

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 o f 2 _C to 40_C (35.6_F – 104_F) with a special option package
available to operate in ambient temperatures ranges from 2_C up to
50_C (35.6_F up to 124_F). The maximum temperature is applicable
to either version up to a maximum elevation of 1000m (3280ft) 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 o f 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 b y 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.

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.

ROUTINE MAINTENANCE

This section refers to the various components which require

periodic maintenance and replacement.

. It should be noted that the intervals between service requirement
may be significantly reduced as a consequence of poor operating
environment. This would include effects of atmospheric contamination
and extremes of temperature.

The SERVICE/MAINTENANCE CHART indicates the various
components’ descriptions and the intervals when maintenance has to
take place. Oil capacities, etc., can be found in the GENERAL
INFORMATION section of this manual.

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 .

CAUTION: Before beginning any work on the compressor, open,
lock and tag the main electrical disconnect and close the isolation
valve on the compressor discharge. Vent pressure from the unit
by slowly unscrewing the coolant fill cap one turn. Unscrewing
the fill cap opens a vent hole, drilled in the cap, allowing pressure
to release to atmosphere. Do not remove the fill cap until all
pressure has vented from the unit. Also vent piping by slightly
opening the drain valve. When opening the drain valve or the
coolant fill cap, stand clear of the valve discharge and wear
appropriate eye protection.

Ensure that maintenance personnel are properly trained,
competent and have read the Maintenance Manuals.

Prior to attempting any maintenance work, ensure that:–

. all air pressure is fully discharged and isolated from the system. If
the automatic blowdown valve is used for this purpose, then allow
enough time for it to complete the operation.

. the machine cannot be started accidently or otherwise.

. all residual electrical power sources (mains and battery) are
isolated.

Prior to opening or removing panels or covers to work inside
a machine, ensure that:–

. anyone entering the machine is aware of the reduced level of
protection and the additional hazards, including hot surfaces and
intermittently moving parts.

. the machine cannot be started accidently or otherwise.

Prior to attempting any maintenance work on a running
machine, ensure that:–
