CAUTION
Deposits and condensate inside the vacuum
pump.
Deposits and condensate in the pump may lead to in ‑
creased temperatures even to the point of exceeding
the maximum permitted temperatures. Deposits may
cause seizing of the pump unit.
>
Check the inlet and outlet of the vacuum pump for
deposits.
>
Check the oil condition.
>
Inspect the pump unit regularly, if there is a danger of
forming deposits inside the vacuum pump. Clean the
pump unit if necessary.
Working materials which get into the vacuum pump with the gas
flow can damage the vacuum pump. Substances can be deposited
in the vacuum pump.

>
Always ensure that the outlet line is clear and has no back
pressure. The outlet must not be blocked, to ensure that
gases can exit freely.
>
Prevent uncontrolled overpressure (e.g., due to a locked or
blocked piping system, condensate, or clogged outlet line).
>
Do not operate the pump with closed outlet. Closing the outlet
during operation may cause damage to pump or components
next in line.
