3. Place the machine where the ambient air is as cool and clean as possible. If
necessary, install a suction duct. Never obstruct the air inlet. Water handling
capacity is limited.
4. Any blanking flanges, plugs, caps and desiccant bags must be removed
before connecting the pipes.
5. Air hoses must be of correct size and suitable for the working pressure. Never
use frayed, damaged or worn hoses. Distribution pipes and connections must
be of the correct size and suitable for the working pressure.
6. 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. Arrange the air intake so that loose clothing worn by people cannot be sucked
in.
8. No external force may be exerted on the inlet and outlet connections; the
connected pipes 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, depressurized
and that the electrical isolating switch is open, locked and labelled with a
temporary warning before any maintenance or repair. As a further safeguard,
persons switching 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
inlet.
11. The electrical connections must correspond to the applicable 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 pump.
12. On machines with automatic start/stop 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 vacuum pump systems, manual valves must be installed to isolate
each pump. Non-return valves (check valves) must not be relied upon for
isolating multiple systems.
14. Never remove or tamper with the safety devices, guards or insulation fitted on
the machine.
15. Piping or other parts with a temperature in excess of 70 ˚C (158 ˚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.
18. Pump outlet air contains traces of oil mist. Ensure compatibility with the
working environment.
