Safety precautions during installation

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.

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. In case the device is a compressor, 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. Care must be taken to
minimize the entry of moisture at the inlet air.

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. In case the device is a compressor, the aspirated air must be free of flammable fumes, vapors and

particles, e.g. paint solvents, that can lead to internal fire or explosion.

7. In case the device is a compressor, arrange the air intake so that loose clothing worn by people cannot

be drawn in.

8. 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.

9. No external force may be exerted on the air outlet valve; the connected pipe must be free of strain.

10. 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 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 on or off 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.

11. 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.

12. 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 compressor.

13. 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.

14. 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.

15. 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.
