• 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.
Secure hose connections at the pump ap-
propriately, e.g., with hose clamps, to protect
against accidental detachment.
NOTICE
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.

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. If this constitutes a potential source of danger,
take appropriate safety measures.
When assembling, ensure vacuum-tightness. After as-
sembly, check the whole system for leaks.
Use a suitable valve to isolate the pump from the vacuum
application. This is to allow the pump to warm up before
pumping condensable vapors and to clean the pump after
use before it is switched off.
