When assembling, ensure vacuum-tightness. After as-

sembly, check the whole system for leaks.

Use a suitable valve to isolate the pump from the vacuum

application. This is to allow the pump to warm up before

pumping condensable vapors and to clean the pump after

use before it is switched off.

NOTICE

Connecting the outlet

Outlet via silencer.

Attention: Use the silencer only in case of low

gas throughput. Check the silencer regularly

for permeability! In case, install a hose nozzle

instead (see „Accessories“, pg. 44).„Accessories“, pg. 44).).

Connecting an exhaust line at the pump outlet:

Unscrew the silencer and install a hose noz-

zle DN 6 mm or a hose nozzle DN 10/6 mm

(thread G1/8”).

➨ If dangerous or polluting uids could be released at

the outlet, install an appropriate system to catch and

dispose of those uids.

NOTICE

outlet

+ Connect a gas-tight exhaust line at the pump

outlet (see above) if necessary. Always vent

exhaust gases appropriately (e.g., into a

fume hood).

+ Never block the gas outlet. The exhaust

line must always be free of obstructions (no

back pressure) to ensure an unimpeded

discharge of gas. The cross-section of the

outlet tubing must be at least the size of the

pump’s exhaust connection.

✔

✘

• Reduce the transmission of vibration. Prevent mechan-

ical load due to rigid pipelines. Insert elastic hoses or

exible elements as couplings between the pump and

rigid pipes.
