7.3.2 Instructions for the Pneumatic Connection
Use only screw unions with cylindrical G-threads for the compressed air and vacuum connection!
To ensure problem-free operation and a long service life of the ejector, only use adequately maintained
compressed air and consider the following requirements:
•
Use of air or neutral gas in accordance with EN 983, filtered 20 μm, oiled or
unoiled.
•
Dirt particles or foreign bodies in the ejector connections, hoses or pipelines
can lead to partial or complete ejector malfunction.
1. Shorten the hoses and pipelines as much as possible.
2. Keep hose lines free of bends and crimps.
