Use a suitable valve (see “Accessories / Spare
parts”, pg. 92) to isolate the pump from the
vacuum application. This is to allow the pump
to warm up before pumping condensable va-
pors and to clean the pump after use before it
is switched off.
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.
NOTICE
Separator (AK) at the inlet
The separator at the inlet protects against
droplets and particles from entering the pump.
☞
Enhances lifetimes of diaphragms and
valves.
☞
Improves vacuum performance in applica-
tions with condensable vapors.
➨
Assemble the separator (AK) with clamping
ring and centring ring KF DN 25.
Catchpot:
The catchpot is coated with a protective layer
to protect against shattering in case of break-
age or implosion.
➨
Assemble the catchpot at the inlet using a
joint clip.
