Product Manual

13. In multiple compressor systems, manual valves must be installed to isolate each
compressor. Non-return valves (check valves) must not be relied upon for isolating pressure
systems.
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 devices as
required.
15. Piping or other parts with a temperature in excess of 80˚C (176˚F) and which may be
accidentally touched by personnel in normal operation must be guarded or insulated. Other
high temperature piping must be clearly marked.
16. For water-cooled machines, 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.
1.4 Safety precautions during operation
All responsibility for any damage or injury resulting from neglecting these precautions, or
non observance of the normal caution and care required for installation, operation,
maintenance and repair, even if not expressly stated, will be disclaimed by the
manufacturer.
These precautions 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.
Some precautions are general and cover several machine types and equipment; hence
some statements may not apply to your machine.
Precautions during operation
1.
Never touch any piping or components of the compressor during operation.
2. Use only the correct type and size of hose end fittings and connections. When blowing
through a hose or air line, ensure that the open end is held securely. A free end will whip
and may cause injury. Make sure that a hose is fully depressurized before disconnecting it.
3. 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 remote start equipment.
4. Never operate the machine when there is a possibility of taking in flammable or toxic fumes,
vapors or particles.
5. Never operate the machine below or in excess of its limit ratings.
6. Keep all bodywork doors shut during operation. The doors may be opened for short periods
only, e.g. to carry out routine checks. Wear ear protectors when opening a door.
7. People staying in environments or rooms where the sound pressure level reaches or
exceeds 90 dB(A) shall wear ear protectors.
8. Periodically check that:
• All guards are in place and securely fastened
• All hoses and/or pipes inside the machine are in good condition, secure and not
rubbing
