Installation and connection
NOTE NOTE
Foreign bodies in the inlet line can damage the
vacuum pump.
>
Prevent particles and contaminants from being aspirated or
being able to flow back.
>
If necessary, install suitable filters upstream of the vacuum
pump to avoid the aspiration of particles and dust. Ensure
that the filters are chemically resistant, clog‑proof and have
a reliable flow rate, appropriate for your application.
>
Do not use rigid pipelines. Rigid pipelines can transmit
mechanical load between the vacuum pump and the appli‑
cation.
>
Use elastic hoses or flexible elements to avoid mechanical
load due to rigid pipelines.
>
Use a sufficiently stable vacuum hose that is designed for
the required vacuum range.
>
Keep the vacuum hose as short as possible.
>
Connect a vacuum hose with as large as possible cross‑
section.
>
The connection between vacuum hose and the vacuum
pump must be gas‑tight.
>
Avoid kinks in the vacuum hose.
Connect the vacuum hose
1. 1. Remove the blind flange on the inlet flange.
>
Connect a vacuum hose with small flange KF DN 16 to the
inlet flange, ensuring the connection is gas‑tight.
>
Alternatively, you can use an adapter from small flange
KF DN 16 to hose nozzle and attach a vacuum hose to it.
Secure hose connections on hose nozzles, e.g., with a hose
clip.
>
If necessary, install an in‑line solenoid valve or shut‑off valve
in the inlet line to isolate your application from the vacuum
pump to allow the pump to warm up before pumping con ‑
densable vapors and to clean the pump after use before it is
switched off.
