Safety information
2.4.4 Eliminate sources of danger
Take mechanical stability into account
Due to the high compression ratio of the pump, pressure can de -
velop at the outlet which exceeds that which the mechanical sta-
bility of the system allows.
>
Always ensure that the exhaust gas line is clear and non-pres-
surized. To ensure unhindered emission of gases, the outlet
should not be blocked.
>
Prevent uncontrolled overpressure, e. g, due to a locked or
blocked piping system, condensate or clogged exhaust gas
line.
>
At the gas connections, the connections for the inlet IN and
outlet EX should 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 74
>
The system to be evacuated as well as all hose connections
must be mechanically stable.
>
Fix coolant hoses to the hose nozzles such that they cannot
inadvertently become loose.
Prevent condensate reflow
Condensate can damage the pump head. No condensate should
flow back into the outlet EX and pump head due to the hose line.
No liquid should accumulate inside the exhaust hose.
>
Avoid condensate return by using a separator. No condensate
must enter the housing interior via the vacuum hoses.
>
Preferably lay the exhaust gas hose such that it descends
from the outlet; that is, position it running downward so that no
backup forms.
Prevent backup in
the exhaust gas line
