6.3 Connecting the vacuum side
Preventing pressure losses
Using the shortest possible vacuum connection lines with large nominal diameter
prevents pressure losses.
Condensate separator
We recommend using a condensate separator in cases where the system to be
evacuated contains fluid, resulting in steam being generated during evacuation.
Connecting the vacuum side
1. Remove the locking cap from the vacuum connection.
2. Install the connection between pump and vacuum system so that it is as short as possible.
3. Install a condensate separator upstream of the pump.
4. Connect the pump to the vacuum system using the vacuum connection.
6.4 Connecting the exhaust side
Condensate separator
We recommend using a condensate separator in cases where the system to be
evacuated contains fluid, resulting in steam being generated during evacuation.
Connecting the exhaust side
1. Observe the official accident prevention regulations.
– This applies in particular where you install a shut-off unit for internal operating reasons, mean-
ing that overpressure can build in the line.
2. Remove protective caps.
3. Install the line downward from the pump, so that condensation does not flow back into the pump.
4. Connect pump and vacuum chambers with the shortest possible connection, with a minimum
nominal diameter equal to that of the vacuum connection.
5. Make sure that no piping system forces are acting on the pump.
6. Support or hang the pipes.
7. Only use the silencer at low gas throughput, and check it regularly to ensure that it is unobstruct-
ed.
