Precautions during installation
1. The machine must only be lifted using suitable equipment in accordance with the applicable safety
regulations. Loose or pivoting parts must be securely fastened before lifting. It is strictly forbidden to
dwell or stay in the risk zone under a lifted load. Lifting acceleration and deceleration must be kept
within safe limits. Wear a safety helmet when working in the area of overhead or lifting equipment.
2. The unit is designed for indoor use. If the unit is installed outdoors, special precautions must be taken;
consult your supplier.
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.
19. Whenever air containing hazardous substances is sucked in (i.e. biological or microbiological agents),
use abatement systems placed upstream of the vacuum pump.
20. Any vacuum pump placed in an application with inlet gas stream temperatures above the published
maximum temperature should be approved by Atlas Copco prior to start-up.
