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.

IRN37 - 160K - CC & IRN50 - 200H -CC & IRN75 - 160K - 2S & IRN100 - 200H - 2S & IRN 250 - 300H - 2S http://air.irco.com

5.0 SAFETY

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 incorrectlyhandled. 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

warning

AVOID INGESTION, SKIN CONTACT AND

INHALATION OF FUMES

For further information, request and consult the coolant Material Data Sheet (UK ACGP 011/96 −ULTRA COOLANT ACGP 029/90−food grade coolant. For USA served areas, use MSDS sheet APDD 236) from your local IR office, Distributor or Air Center.

Should compressor lubricant come into contact with the eyes, then irrigate with water for at least 5 minutes.

Should compressor lubricant come into contact with the skin, then wash off immediately.

Consult a physician if large amounts of compressor lubricant are ingested.

Consult a physician if compressor lubricant is inhaled.

Never give fluids or induce vomiting if the patient is unconscious or having convulsions.

The above information contains data supplied in support of United Kingdom Control of Substances Hazardous to Health (C.O.S.H.H.) regulations

Transport

When loading or transporting machines ensure that the 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-General Information 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.

5.0 SAFETY

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 IRACA145 or APDD190.

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.

All 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.

For 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.

It is the responsibility of the installer and owner to provide the appropriate service pipework to and from the machine.

warning

“Ingersoll Rand air compressors are not designed, intended, or approved for breathing air applications. Ingersoll Rand does not approve specialized equipment for breathing air application and assumes no responsibility or liability for compressors used for breathing air services.”

warning

No portable communication devices emitting more than 7.5 volts per metre in the frequency range from 250 MHz to 280 MHz should be operated within 5m (16.5ft) of the unit.

warning

The motor rotor contains a powerful magnetic field. This field can effect the operation of digital devices such as watches, mobile phones etc. Assembly or handling of the rotor should not be attempted by personnel with cardiac pacemakers, defibrillators or other implanted electronic medical device.

warning

The specification of this machine is such that the machine is not suitable for use in flammable gas risk areas. If such an application is required then all local regulations, codes of practice and site rules must be observed. To ensure that the machine can operate in a safe and reliable manner, additional equipment such as gas detection and intake (shut−off) valves may be required, dependant on local regulations or the degree of risk involved.

warning

The compressor can operate in a pressurized shutdown mode. If the compressor stops automatically, the airend, separator tank and oil system can contain high pressure air. This can be relieved by pressing the emergency stop button and can be verified by unscrewing the coolant fill plug which has a vent hole through which any residual pressure will be vented. Downstream of the separator tank may still contain system pressure which must also be vented

7.0 INSTALLATION

For technical information see section 8.0.

7.1 LOCATION IN PLANT

Ensure that the correct tie down points are used.

For major overhaul (i.e. motor removal) position the machine to obtain lifting access e.g. fork lift truck.

See diagram in reference section for minimum space requirements for normal operation and maintenance.

Ambient temperatures higher than 46° C (115° F) must be avoided as well as areas of high humidity.

Consider also the environment surrounding or near the compressor. The area selected for the location of the compressor should be free of dust, chemicals, metal filings, paint fumes and overspray.

Hard surfaces may reflect noise with an apparent increase in the decibel level. When sound transmission is important, a sheet of rubber or cork can be installed beneath the machine to reduce noise. Flexible piping may be required.

It is recommended that provision be made for lifting heavy components during major overhaul. Use only lifting points provided.

Minimum space in front of control panel door as required by National or Local codes must be maintained.

The compressor can be installed on any level floor capable of supporting it. A dry, well ventilated area where the atmosphere is as clean as possible is recommended.

Sufficient space all round and above the compressor must be allowed, to enable the effective removal of the cooling air which, in turn, will reduce the risk of recirculating the cooling air back through the compressor.

caution

A minimum of 1 m (3.3ft) all round the compressor is recommended. If headroom is restricted, then the exhaust should be ducted or deflected away from the machine.

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.

The machine is shipped with the shipping restraints in place. Ensure that these are removed to allow free movement of the drive assembly during operation. Each restraint is painted yellow.

7.0 INSTALLATION

7.2 DISCHARGE AND CONDENSATE PIPING

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.

A receiver [2] may be necessary to ensure that the total system volume is not less than 2.0 U.S. Gal. per rated delivery C.F.M.

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 good practice to locate an isolation valve close to the compressor and to install line filters [4].

Include a means [6] to vent the discharge pipework downstream from the minimum pressure check valve located on the separator tank. Upstream of the first system isolation valve [7].

The discharged air contains a very small percentage of compressor lubricating oil and care should be taken to ensure that downstream equipment is compatible.

When two rotary units are operated in parallel, provide an isolation vaIve and drain trap for each compressor before the common receiver.

The built−in aftercooler reduces the discharge air temperature below the dew point (for most ambient conditions), therefore, considerable water vapor

is condensed. To remove this condensation, each compressor with built−in aftercooler is furnished with a combination condensate separator/trap.

A dripleg assembly and isolation valve should be mounted near the compressor discharge. A drain line should be connected to the condensate drain in the base.

IMPORTANT: The drain line must slope downward from the base to work properly. For ease of inspection of the automatic drain trap operation, the drain piping should include an open funnel.

NOTICE

For low volume systems that may not include a receiver [2], compressor response time may need adjusting. Contact your local IR service agent.

caution

The use of plastic bowls on line filters and other plastic air line components without metal guards can be hazardous. Their safety can be affected by either synthetic coolants or the additives used in mineral oils. From a safety standpoint, metal bowls should be used on any pressurized system.

NOTICE

Do not use the compressor to support the discharge pipe.

7.0 INSTALLATION

7.3 ELECTRICAL

caution

This procedure should only be carried out by a qualified electrician, electrical contractor or your local Ingersoll Rand Distributor or Air Center.

The compressor and drive should be properly grounded / earthed in accordance with Local and National Code requirements.

Installation of this compressor must be in accordance with recognized electrical codes and any local Health and Safety Codes.

The compressor must have its own isolator situated adjacent to it. The fuse protecting the circuit and the compressor must be selected in accordance with local and national code requirements on the basis of the data provided in the general information section

Feeder cables 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.

Cable sizes may vary considerably so the mains terminals will accept up to 50mm2 (1awg) (37/45k & 50/60H) and up to 90mm2 (3/0awg) (55/75k & 75/100H) cable. The N75K−160K and N100H−200H

machines mains terminals will accept 2 x 120mm2 (4/0 AWG) cables. The N250H−300H−2S machines main terminals will accept 2 x 400 MCM cables.

Feeder cable connections to incoming terminals L1−L2−L3 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.

A hole is provided for incoming power connection. If it is necessary to make a hole in the control box in a different location, care should be taken to not allow metal shavings to enter the starter and other electrical components within the box. If another hole is used, the original hole must be blocked off.

The feeder cable must be suitably glanded into the power drive module (P.D.M.) electrical box to ensure that dirty air does not by−pass the filter pads or degrade the cooling air flow.

On completion of electrical installation, check that blower motor rotation is correct. N250H−300H utilizes a fan.

This machine is designed for use in heavy industrial environments, where the electricity supply is separated from nearby residential and commercial areas. If the machine is to be used in the light industrial, residential or commercial environment where the local supply network is shared, further radio frequency (RF) screening measures may be required. Consult your local distributor/supplier for details of the optional RF filter. RF filter supplied as standard on N250−300H−2S

The compressor has a anti−condensation heater and thermostat in the electrical box. This circuit can be connected to an independent electrical supply of either 110V or 230V single phase, dependant on the country of installation. The supply should be suitable fused

and an independent isolator installed adjacent to the compressor.

This should be done in accordance with local and national codes. It is good practice and sometimes mandatory, to display suitable signs warning that the machine has two separate electrical supplies which both must be isolated before any work is attempted.

Alternately it can be supplied from the 110V tapping of the control transformer and connected as shown on schematic wiring diagram.

7.0 INSTALLATION

caution

VERY IMPORTANT

Supply voltage must be kept to a maximum imbalance of 2% on 50Hz and 3% on 60Hz applications. Voltage imbalances greater than these levels can cause permanent damage to the drive.

Compressor must not be subjected to any voltage spikes or surges in excess of 575V. Exposure to spikes/surges in excess of 575V can permanently damage the drive. If the possibility of such exists it is recommended that adequate surge protection is fitted such as an Ingersoll Rand line reactor. See your local Ingersoll Rand representative.

Failure of the drive due to voltage spikes, line notching, harmonics or other power quality related problems, will not be covered by the standard compressor warranty.

The correct type and rating of line input fuse MUST BE fitted onto the customers isolator or breaker close to the compressor. For Amp rating see technical information in Section 8.1.

Cooling Water Piping

 

Venting the water system

 

 

 

 

Water piping to and from the compressor package must be 1”diameter or larger for N37/75K (N50/100H), 11/2” diameter or larger for N75/160K (N100H/200H) and 2.0” diameter or larger for N250/300H−2S. Isolation valves with side drains should be installed on both the inlet and outlet lines. Also a strainer of 2mm−mesh size should

be installed on the inlet line. Strainers are available from Ingersoll Rand. Ingersoll Rand CPN 54689997 (N37/45K & N50/60H) or CPN 54690029 (N55/75K & N75/100H)

A normally closed solenoid valve is fitted to the water outlet side of the compressor package. This is wired into the compressor control circuit and closes when the compressor stops.

Carefully inspect your water system before installing the compressor package. Ensure that the piping is free of scale and deposits that may restrict water flow to the compressor package.

Proper operation of your compressor requires that the water flow listed below be provided at a maximum supply temperature of 46° C (115° F).

Water temperature and pressure gauges should be installed in the water piping for use in any fault finding of the water system. Water pressure should ideally be between 3 and 5 bar (43.5 and 72.5 psi) but must not be above 10 Bar (145 psi)

Water cleanliness is also extremely important. Cleaning of coolers as a result of fouling is a customer responsibility. Therefore, it is highly recommended that proper water quality must meet the requirements listed in WATER QUALITY RECOMMENDATIONS later in this section.

At the initial installation or for start−up after draining the water system proceed to vent the system as follows.

1.Locate the water system vent cocks on top of the aftercooler and lubricant cooler.

2.Open the water valve(s) allowing water to flow to the package.

3.Open the vent cocks and allow all air to escape from the system. When water is observed at the vent cocks, close them.

The system is now vented.

Draining the water system

Should it become necessary to completely drain the water system, proceed as follows.

1.Disconnect the inlet and discharge water lines from the connections located at the rear of the unit.

2.Locate the aftercooler and lubricant cooler. Remove the drain plugs located at the bottom of the coolers. Allow the system to completely drain.

N75−160k, N100−200H Watercooled

See piping and instrumentation diagram (Section 8.3). The coolers are piped in a ”parallel” water flow arrangement with a manual trim valve controlling the flow through the aftercooler. An additional automatic anti−condensation thermal valve controls the flow of water to the oilcooler. It has a sensor in the separator

tank and capillary to signal the valve to open and close in order to avoid water condensing in the tank.

Adjusting the Aftercooler Trim Valve

The anti−condensation valve has no adjustment. The Aftercooler Trim Valve is factory set and should not need adjusting but if disturbed use following procedure. Close valve fully clockwise and then open 1/4 turn. With machine running loaded observe the package discharge temperature Intellisys display. It should be be approx 15° F (8° C) above the water inlet temperature. If it is higher, open the valve a little more. Put a ’Warning − Do Not Adjust’ label on the valve or fit a lock.

Water quality recommendations

Water quality recommendations Water quality is often overlooked when the cooling system of a water−cooled air compressor is examined. Water quality determines how effective the heat transfer rate, as well as the flow rate will remain during the life of the unit. It should

be noted that the quality of water used in any cooling system does not remain constant during the operation of the system. Evaporation, corrosion, chemical and temperature changes, aeration, scale and biological formations effect the water makeup. Most problems in a cooling system show up first in a reduction in the heat transfer rate, then in a reduced flow rate and finally with damage to the system.

Scale: Scale formation inhibits effective heat transfer, yet it does help prevent corrosion. Therefore, a thin uniform coating of calcium carbonate is desired on the inner surface. Perhaps the largest contributor to scale formation is the precipitation of calcium carbonate out of the water. This is dependent on temperature and pH. The higher the pH value, the greater the chance of scale formation. Scale can be controlled with water treatment.

Corrosion: In contrast to scale formation is the problem of corrosion. Chlorides cause problems because of their size and conductivity. Low pH levels promote corrosion, as well as high levels of dissolved oxygen.

Fouling: Biological and organic substances (slime) can also cause problems, but in elevated temperature environments such as cooling processes they are not a major concern. If they create problems with clogging, commercial shock treatment are available.

To ensure good operation life and performance of the compressor cooling system, the recommended acceptable ranges for different water constituents are included below:

7.5 SEA WATERCOOLED UNITS (SELECTED UNITS ONLY)

Water cleanliness is extremely important. Strainers are available from Ingersoll Rand. Cleaning of coolers as a result of fouling is a customer responsibility.

Isolation valves with side drains should be installed on both the inlet and outlet lines.

A normally closed solenoid valve is fitted to the water outlet side of the compressor package.

It is important to ensure that the recommended flow rate cannot be exceeded. This will normally mean that an orifice plate must be fitted in the pipework at least 1m (3.3ft) before the cooler, with the orifice size calculated to ensure that the maximum sea water flow rate cannot be exceeded. If these precautions are not taken, it is possible that the sea water flow rate through the cooler may be several times the recommended maximum, which will lead to rapid failure.

No oil cooler manufacturer can guarantee that its products will have an indefinite life and for this reason, we suggest that the cooling system is designed to minimize any damage caused by a leaking oil cooler. This can be achieved as follows ;

1.The oil pressure should be higher than the sea water pressure, so that in the event of a leak occurring, the oil will not be contaminated.

2.If the sea water pressure is 100PSIG (7BARG) or above it is recommended that the water solenoid valve is changed to the water inlet side. This will protect the system from high pressure surges when not in use.

3.The sea water outlet pipe from the cooler should have a free run to waste.
