of moisture at the inlet air.
3. Any blanking flanges, plugs, caps and desiccant bags must be removed before connecting
the pipe.
4. Air hoses must be of correct size and suitable for the working pressure. Never use frayed,
damaged or worn hose. Distribution pipes and connections must be of the correct sixe and
suitable for the working pressure.
5. The aspirated air must be free of flammable fumes, vapours and particles, e.g. paint
solvents, that can lead to internal fire or explosion.
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 materials.
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 machine must bear a clear sign stating: DANGER: This
machine is remotely controlled and may start without warning.
The operator has to make sure that the machine is stopped and that the isolating switch is
open and locked before any maintenance or repair. As a further safeguard, persons
switching on remotely controlled machines 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. Air-cooled machines must 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 compressor air inlet or
cooling air inlet.
11. The electrical connections must correspond to the local codes. The machines must be
earthed and protected against short circuits by fuses in all phases. A lockable power
isolating switch must be installed near the compressor.
12. On machines with automatic start-up system or if the automatic restart function after
voltage failure is activated, a sign stating
”
This machine may start without warning
”
must
be affixed near the instrument panel.
13. In multiple compressor system, Manual valves must be installed to isolated each
compressor. Non-return valves( check valves) must not be relied upon for isolating
pressure system.
14. Never remove or tamper with the safety devices, guards or insulation fitted on the machine.
Every pressure vessel or auxiliary installed outside the machine to contain air above
atmospheric pressure must be protected by a pressure- relieving device or device as
required.
15. Pipe work or other parts with a temperature in excess of 80 degree C (176 degree F) and
which may be accidentally touched by personnel in normal operation must be guarded or
isolated. Other high-temperature pipework must be clearly marked.
16. For water-cooled machine, the cooling water system installed outside the machine has to
be protected by a safety device with set pressure according to the maximum cooling water
inlet pressure.
17. If the ground is not level or can be subject to variable inclination, consult the manufacturer.
Also consult following safety precautions; Safety precautions during
operation and safety precautions during maintenance.
These precautions apply to machinery processing or consuming air or inlet
gas.
Processing of any other gas requires additional safety precautions typical
to the application which are not included herein.
Some precautions are general and cover several machine types and
equipment, hence some statements may not apply to your machine.
