Connect the tubing correctly
No inadmissible pressure must be created at the vacuum pump
outlet. If the back pressure at the outlet is inadmissibly high,
pumped media may escape,

>
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).
>
At the gas connections, the connections for the inlet and
outlet must not be mixed up. The inlet is indicated by a
directional arrow on the connecting flange.
>
Observe the maximum pressures at the inlet and outlet of the
vacuum pump, as specified in chapter
8.1.1 Technical data 8.1.1 Technical data

.
>
The system to be evacuated as well as all hose connections
must be mechanically stable.
>
Attach hoses to optional hose nozzles (e.g., vapor condenser,
adapters at pump connections) so that they do not come
loose unintentionally.
Sealing gas to protect the vacuum pump
To protect the bearings of the vacuum pump, a permanent gas
flow (ambient air sucked in inside the pump casing, hereinafter
referred to as sealing gas) is added at the outlet side of the suction
chamber. This mixes with the pumped media and is conveyed to
the pump outlet. Pumped media can form reactive mixtures with
the sealing gas (ambient air).
>
Do not use the vacuum pump in processes in which the
pumped media can form an explosive mixture with air.
Avoid overpressure
