1.3 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 the manufacturer.
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. 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. 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. Arrange the air intake so that loose clothing worn by people cannot be sucked in.
8. Ensure that the discharge pipe from the dryer to the 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 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.
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 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 dryer.
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. 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.
