• Reduce the transmission of vibration. Pre-
vent mechanical load due to rigid pipelines.
Insert elastic hoses or flexible elements as
couplings between the pump and rigid pipes.
Note: Flexible elements will compress or
flatten when evacuated if not designed for
use under vacuum.
• Hose connections at the pump inlet must al-
ways be gas tight.
Use connecting hoses with large diameter and
keep them as short as possible to avoid flow
losses. Locate the pump as closely as possi-
ble to the application.
NOTICE
✘
✔
Secure hose connections at the pump ap-
propriately, e.g., with hose clamps, to protect
against accidental detachment.
NOTICE
+
Particles and dust must not be aspirated. If necessary,
you must install appropriate filters. You must ensure
their suitability concerning gas flow, chemical resis-
tance and resistance to clogging prior to use.
• A power failure may cause accidental ventilation of the
pump, especially if the gas ballast valve is open. If this
constitutes a potential source of danger, take appropri-
ate safety measures.
When assembling, ensure vacuum-tightness. After as-
sembly, check the whole system for leaks.
