Handling Teflon hoses and connections
Pay attention to the following points when handling Teflon
hoses:
− Do not kink the hoses.
− Avoid excess mechanical strain on the Teflon hoses.
− When reconnecting, push the connections completely
onto the fittings and tighten the lock-nuts up to the
stop.
− If white stress marks can be seen on a hose, replace it
– white marks on Teflon hoses indicate damages.
− When shortening hoses, cut at right angles using a
sharp knife (do not pinch off or crimp using side
cutters or similar tools).
Perform a test run after service and maintenance
After service or maintenance you must always perform a test
run and check the equipment for anything unusual (e.g. leaks,
noises).
