9. If compressed air is used in the food industry and more specifically for direct food contact, Pneumatech
recommends, for optimal safety, the use of certified Class 0 compressors in combination with appropriate
filtration depending on the application. Please contact your Pneumatech Customer Center for advice on
specific filtration.
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.
3. Place the machine where the ambient air is as cool and clean as possible.
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. 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.
7. No external force may be exerted on the air outlet valve; the connected pipe must be free of strain.
8. 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.
9. 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.
10. 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.
11. 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.
12. Pipework 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
pipework must be clearly marked.
13. 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 .
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.
