Safety information
2.4.4 Eliminate sources of danger
Take mechanical stability into account
The high compression ratio of the pump may result in a higher
pressure at the outlet than the mechanical stability of the system
allows.
>
Always ensure that the outlet line is clear and non‑pressur‑
ized. 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 IN and
outlet EX must not be mixed up.
>
Be aware of the max. pressures at the inlet and outlet of the
pump as well as the max. admissible differential pressure
between the inlet and outlet, according to 8.1.1 Technical data
on page 75 .
>
The system to be evacuated as well as all hose connections
must be mechanically stable.
Prevent condensate return
Condensate can damage the pump head. Condensate must not
flow back into the outlet EX or pump head through the hose line.
Liquid must not accumulate inside the exhaust gas hose.
>
Avoid condensate return by using a separator (accessory).
Condensate must not enter the inside of the housing via the
hose lines.
>
Preferably route the exhaust gas hose with a fall from the out‑
let, i.e., running downward so that no backup forms.
Prevent backup in
the outlet line
