SAFETY PRECAUTIONS
To 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 requires
additional safety precautions typical to the application which are not included herein.
In addition to normal safety rules which should be observed with stationary
air compressors and equipment, the following safety directions and
precautions are 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 modification on the compressor shall only be performed in agreement
with Atlas Copco and under supervision of authorized, competent
personnel.
If any statement in this book, especially with regard to safety, does not
comply with local legislation, the stricter of the two shall apply.
These precautions are general and cover several machine types and
equipment; hence some statements may not apply to the unit(s) described
in this book.
Installation
Apart from general engineering practice in conformity with the local safety
regulations, the following directives are specially stressed:
1. A compressor shall be lifted only with adequate equipment in
conformity with local safety rules.
Loose or pivoting parts shall be securely fastened before lifting. It
is strictly forbidden to 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 lifting
equipment.
2. Any blanking flanges, plugs, caps and desiccant bags shall be
removed before connecting up the pipes. Distribution pipes and
connections shall be of correct size and suitable for the working
pressure.
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.
Care shall 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 not
recirculate to the inlet.
6. Arrange the air intake so that loose clothing of people cannot be
sucked 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 in contact
with or close to flammable material.
8. No external force may be exerted on the air outlet valve; the
connected pipe must be free of strain.
9. If remote control is installed, the unit shall bear an obvious sign
reading:
DANGER: This machine is remotely controlled and may start
without warning.
As a further safeguard, persons switching on remotely controlled
units shall take adequate precautions to ensure that there is no one
checking or working on the machine. To this end, a suitable notice
shall be affixed to the start equipment.
10. On units with automatic start-stop system, a sign stating "This
machine may start without warning" shall be attached near the
instrument panel.
11. In multiple compressor systems manual valves shall be installed to
isolate each compressor. Non-return valves (check valves) shall
not be relied upon for isolating pressure systems.
12. Never remove or tamper with the safety devices, guards or
insulations fitted on the unit. Every pressure vessel or auxiliary
installed outside the unit to contain air above atmospheric pressure
shall be protected by a pressure-relieving device or devices as
required.
