SAFETY PRECAUTIONSTo be read attentively and acted accordingly before installing, operating or repairing the unit.

These recommendations apply to machinery processing or consuming air or inert gas. Processing of any other gas requiresadditional safety precautions typical to the application which are not included herein.

In addition to normal safety rules which should be observed with stationery air compressors and equipment, the following safety directions and precautionsare of special importance.

When operating this unit, the operator must employ safe working practices and observe all related local work safety requirements and ordinances.

The owner is responsible for maintaining the unit in a safe operating condition. Parts and accessories shall be replaced if unsuitable for safe operation.

Installation, operation, maintenance and repair shall only be performed by authorized, trained, competent personnel.

Normal ratings (pressures, temperatures, time settings etc.) shall be durably marked.

Any modifications on the compressor shall only be performed in agreement with CP and under supervision of authorized, competent personnel.

If any statement in this book, especially with regard to safety, does notcomply with local legislation, the stricter of the two shall apply.

These precautions are general and cover several machine types andequipment; hence some statements may not apply to the unit(s) describedin this book.

Installation

Apart from general engineering practice in conformity with the local safetyregulations, the following directives are specially stressed:

1. A compressor shal l be l i f ted only with adequate equipment inconformity with local safety rules.

Loose or pivoting parts shall be securely fastened before lifting. It isstrictly forbidden do dwell or stay in the risk zone under a lifted load.Lifting acceleration and retardation shall be kept within safe limits.

Wear a safety helmet when working in the area of overhead or liftingequipment.

2. Any blanking f langes, plugs, caps and desiccant bags shall beremoved before connecting up the pipes. Distribution pipes andconnections shall be of correct size and suitable for the workingpressure.

3. Place the unit where the ambient air is as cool and clean as possible.If necessary, install a suction duct. Never obstruct the air inlet. Careshall be taken to minimize the entry of moisture with the inlet air.

4. The aspirated air shall be free from flammable fumes or vapours,e.g. paint solvents, that can lead to internal fire or explosion.

5. Air-cooled units shall be installed in such a way that an adequate

flow of cooling air is available and that the exhausted air does notrecirculate to the inlet.

6. Arrange the air intake so that loose clothing of people cannot besucked in.

7. Ensure that the discharge pipe from the compressor to the aftercooler or air net is free to expand under heat and that it is not incontact with or close to flammable material.

8. No external force may be exerted on the air outlet valve; theconnected pipe must be free of strain.

9. If remote control is installed, the unit shall bear an obvious signreading:

DANGER: This machine is remotely controlled and may startwithout warning.

As a further safeguard, persons switching or remotely controlledunits shall take adequate precautions to ensure that there is no onechecking or working on the machine. To this end, a suitable noticeshall be affixed to the start equipment.

10. On units with automatic start-stop system, a sign stating “Thismachine may start without warning” shall be attached near theinstrument panel.

11. In multiple compressor systems manual valves shall be installed toisolate each compressor. Non-return valves (check valves) shall notbe relied upon for isolating pressure systems.

12. Never remove or tamper with the safety devices, guards or insulationsfitted on the unit. Every pressure vessel or auxiliary installed outsidethe unit to contain air above atmosph eric. pressure shall be protectedby a pressure-relieving device or devices as required.

13. Pipework or other parts with a temperature in excess of 80 degresscelsius and which may be accidentally touched by personnel in normaloperation shall be guarded or insulated. Other high-temperature pipeworkshall be clearly marked.

14. If the ground is not level or can be subject to variable inclination, consultChicago Pneumatic.

15. The electrical connections shall correspond to the local codes. Theunits shall be grounded and protected against short circuits by fuses.

Operation

1. Air hoses shall be of correct size and suitable for the working pressure.Never use frayed, damaged or deteriorated hoses. Use only the correcttype and size of hose and fittings and connections. When blowing througha hose or air line, ensure that the open end is held securely. A free endwil l whip and may cause injury. Make sure that a hose is ful lydepressurized before disconnecting it.Never play with compressed air. Do not apply it to your skin or direct anair stream at people. Never use it to clean dirt from your clothes. Whenusing it to clean equipment, do so with extreme caution and use eyeprotection.

2. The compressor is not considered as capable of producing air ofbreathing quality. For breathing air quality, the compressed air must beadequately purified according to local legislation and standards.

3. Never operate the unit when there is a possibility of taking in flammableor toxic fumes.

4. Never operate the unit at pressures below or in excess of its limit ratingsas indicated on the Principal Data sheet.

5. Keep all bodywork doors shut during operation. The doors may be openedfor short period ony e.g. to carry out checks. Wear ear protectors whenopening a door.

6. People staying in environments or rooms where the sound pressurelevel reaches or exceeds 90 dB (A) shall wear ear protectors.

7. Periodically check that:a. All guards are in place and securely fastened

b. All hoses and / or pipes inside the unit are in good condition, secureand not rubbing.

c. There are no leaksd. All fasteners are tight

e. All electrical leads are secure and in good order.f. Safety valves and other pressure - relief devices are not obstructed

by dirt or paint.

g. Air outlet valve and air net, i.e. pipes, couplings, manifolds, valves,hoses, etc. are in good repair, free of water or abuse.

8. If warm cooling air from compressors is used in air heating systems e.g.to warm up a workroom, take precautions against air pollution andpossible contamination of the breating air.

9. Do not remove any of, or tamper with, the sound - damping material.

MaintenanceMaintenance and repair work shall only be carried out under supervisior of

someone qualified for the job.

1. Use only the correct tools for maintenance and repair work.2. Use only genuine spare parts.

3. All maintenance work, other than routine attention, shall only beundertaken when the unit is stopped, the main power supply is switchedoff and the machine has cooled down. Take positive precaution to ensurethat the unit cannot be started inadvertently. In addition, a warning signbearing a legend such as “work in progress; do not start” shall be attached

to the srarting equipment.4. Before removing any pressurized component, effectively isolate the unit

from all sources of pressure and relieve the entire system of pressure.

5. Never use flammable solvents or carbon tetrachloride for cleaning parts.Take safety precautions against toxic vapours of cleaning liquids.

6. Scrupulously observe cleanlines during maintenance and repair. Keepdirt away by covering the parts and exposed openings with a clean cloth,paper or tape.

7. Never weld or perform any operation involving heat near the oil system.Oil tanks must be completely purged. e.g. by steam-cleaning, beforecarrying out such operations.Never weld on, or in any way modify, pressure vessels.

Whenever there is an indication or any suspicion that an internal part ofa machine is overheated, the machine shall be stopped but no inspectioncovers shall be opened before sufficient cooling time has elapsed; thisto avoid the risk of spontaneous ignition of the oil vapour when air isadmitted.

Never use a light source with open flame for inspecting the interior ofmachine, pressure vessel, etc.

8. Make sure that no tools, loose parts or rags ae left in or on the unit.9. Before cleaning the unit for use after maintenance or overhaul, check

that operating pressures, temperaturea and time settings are correctand tha the control and shut-down devices function correctly. If removed,check that the coupling guard of the compressor drive shaft has beenreinstalled.

10. Every time the separator element is renewed, examine the dischargepipe and the inside of the oil separator vessel for carbon deposits; ifexcessive, the deposits should be removed.

11. Protect the motor, air filter, electrical and regulating components, etc. toprevent moisture from entering them e.g. when steam-cleaning.

12. Make sure that all sound-damping material, e.g. on the bodywork and inthe air inlet and outlet systems of the compressor, is in good condtions.If damaged, repalce it by genuine CP material to prevent the soundpressure level from increasing.

13. Never use caustic solvents which can damage materials of the air net,e.g. polycarbonate bowls.

14. The following safety precautions are stressed when handling refregerant:a Never inhale refrigerant vapours. Check that the working area is

adequately ventilated; if rquired, use breathing protection.b Always wear special gloves. In case of regrigerant contact with

the skin, rinse the shin with water. If liquid refrigerant contacts theskin through clothing, never tear off or remove the latter; flushabundantlty with fresh water over seek medical until all regrigerantis flushed away; then seek medical first aid.

c Always wear safety glasses.

15. protect hands to avoid injury from hot machine parts, e.g. during drainingof oil.

Note : With stationery machine units driven by an internalcombustion engine, allowance has to be made for

extra safety precautions, e.g. sparkarrestors, fuelling care, etc. C o n s u l tChicago Pneumatic.

All responsibility for any damage or injury resulting from neglectingthese precautions, or by non-obsrvance of ordinary caution and duecare required in handling, operating, maintenance or repair, evenif not expressly mentioned in this book, will be discalimed byChicago Pneumatic.
