5.2 SAFETY PRECAUTIONS
General Information
Compressed air and electricity can be dangerous.
Before undertaking any work on the compressor,
ensure that the electrical supply has been isolated,
locked off, tagged and the compressor has been
relieved of all pressure.
Make sure that all protective covers are in place and
that the canopy/doors are closed during operation.
Installation of this compressor must be in accordance
with recognized electrical codes and any local Health
and Safety Codes.
Use only safety solvent for cleaning the compressor
and auxiliary equipment.
Compressed air
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 check valves and
isolation valves must be fitted and controlled by work
procedures, so that one machine cannot accidentally
be pressurized / over pressurized by another.
If 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).
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.
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.
When using compressed air always use appropriate
personal protective equipment.

http://air.irco.com 7
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.
The safety valve located in the separator tank must be
checked periodically for correct operation.
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.
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

specified lifting and tie down points are used.
It is recommended that the machine be moved using
the fork lift slots in the machine base.
Refer to section 8 for reference information.
Electrical
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 using a manual disconnect
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 in
accordance with National and Local code
requirements.
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.
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
Condensate cannot be discharged into fresh/surface
water drains. In some regions compressor condensate
containing ULTRA COOLANT can be fed directly into a
drainage system that has downstream sewage
treatment.
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.
Coolant disposal
Steps to be taken in the case of spillage: Soak up with
a suitable absorbent material, then sweep into a plastic
bag for disposal.
Burn in an approved incinerator, or according to local
area or country regulations.
For further information, consult ULTRA COOLANT
Material Data Sheets ACGP 011/96 or APDD 236.
FOOD GRADE COOLANT Material Data Sheets

WARNING
This compressor contains a variable frequency drive. When it is switched off and the motor is stopped, the
internal capacitors store a potentially lethal high voltage. DO NOT REMOVE THE DRIVE COVER or attempt
any work on the drive unless trained. There are no user serviceable items behind the cover.
WARNING
There is a high discharge air temperature shutdown function built into each compressor. lt is factory preset
at 109_C (228_F).This function should be checked at regular intervals for proper operation, once a month is
recommended. Refer to maintenance section.
Failure to adhere to these recommendations can result in mechanical failure, property damage and serious
injury or death.
SAll 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.
SFor the foregoing reasons, the use of plastic piping 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.
SIt is the responsibility of the installer and owner to provide the appropriate service pipework to and from
the machine.

OUR RESPONSIBILITY FOR THIS SHIPMENT CEASED WHEN THE CARRIER SIGNED
BILL OF LADING
If goods are received short or in damaged condition, it is important that you notify the carrier and insist on a
notation of the loss or damage across the face of the freight bill. Otherwise no claim can be enforced against the
transportation company.
If concealed loss or damage is discovered, notify your carrier at once and request an inspection. This is absolutely
necessary. Unless you do this the carrier will not entertain any claim for loss or damage. The agent will make an
inspection and grant a concealed damage notation. If you give the transportation company a clear receipt for
goods that have been damaged or lost in transit, you do so at your own risk and expense.
WE, AT lR, ARE WILLING TO ASSIST YOU IN EVERY POSSIBLE MANNER TO COLLECT CLAIMS FOR LOSS
OR DAMAGE, BUT THE WILLINGNESS ON OUR PART DOES NOT MAKE US RESPONSIBLE FOR
COLLECTION OF CLAIMS OR REPLACEMENT OF MATERIAL. THE ACTUAL FILING AND PROCESSING OF
THE CLAIM IS YOUR RESPONSIBILITY.

6.2 UNPACKING AND HANDLING
The compressor will normally be delivered with a polyethylene or other cover. If a knife has to be used to remove this
cover, ensure that the exterior paintwork of the compressor is not damaged.
Incorporated within the base of the compressor are slots to enable a fork lift truck to move the machine. Ensure truck
forks are fully engaged on both sides. Alternatively a special lifting frame can be utilized to enable a crane or hoist to
move the compressor. Use only marked lifting points.
Once the packaging and pallet are discarded and the unit is in its final position, remove the transit brackets from the
resilient mounts and store for future use or discard.
On N75−160 units remove the screw in the base and slide the separator tank service bracket into the upper position
on the slots and tighten screws.
