NOTICE Avoid throttling losses by using connecting pipes with large diameter and by keeping
them as short as possible.
Assemble silencer or hose nozzle at the outlet of the pump.
Attention: Use the silencer only in case of small gas throughput. Check the silencer
regularly for permeability!
Install outlet pipelines always falling to avoid backflow of condensate towards the
pump.
Use of a suitable valve to isolate the pump from the vacuum system is recommended
to allow the pump to warm up before pumping condensable vapours or to clean the
pump before it is switched off.
When assembling, ensure vacuum-tightness. After assembly, check the whole sys-
tem for leaks.
Secure hose connections at the pump appropriately against unintentional detach-
ing.

Connection lines at the pump inlet have to be gas tight. Particles and dust must
not be aspirated, the user has to provide appropriate filters if necessary. The user
must ensure their suitability concerning gas flow, chemical resistance and safe-
ness against clogging prior to use.
Connect an exhaust line gas tight at the pump outlet if necessary. Always dispose
of exhaust gases appropriately (e.g. into a fume hood). If there is risk of release of
dangerous or polluting fluids, install an appropriate system to catch and dispose
of those fluids.
Reduce the transmission of vibration and prevent mechanical load due to rig-
id pipelines. Insert elastic hoses or flexible elements as couplings between the
pump and rigid pipes. Attention: Flexible elements tend to shrink when evacu-
ated.
The gas outlet must never be blocked. The exhaust line has always to be free
(pressureless) to ensure an unimpeded discharge of gas.
A power failure may cause unintentional ventilation of the pump. In case this con-
stitutes a potential source of danger, take appropriate safety measures.
Make sure ventilation is adequate especially if the pump is installed in a housing
or if the ambient temperature is elevated. Provide external ventilation if neces-
sary.
During operation
Maximum ambient temperature: 40 °C
Make sure ventilation is adequate especially if the pump is installed in a housing
or if the ambient temperature is elevated. Keep a distance of minimum 20 cm
between fan (underside the pump) and ambient parts (e.g. housing, walls, ...).
Potentially dangerous gases or vapours at the outlet of the pump have to be
drained and disposed appropriately.
