Commissioning (operation) 5.2.4 Operation with gas ballast Description The provision of gas ballast (= addition of gas) ensures that va- pors do not condense inside the vacuum pump but are instead ejected from the pump. This makes it possible to pump larger amounts of condensable vapors, and also prolongs the service life.
Commissioning (operation) 5.3 Shutdown (switch off) Shut down the pumping unit Switch off pumping 1. Stop the process and let the pumping unit run on for about unit 30 minutes, with open gas ballast or open inlet (IN). Condensate and media residues will be flushed out of the vacuum pump.
Commissioning (operation) 5.4 Storage Store the pumping unit 1. Clean the pumping unit if required. 2. Recommendation: Perform preventative maintenance be- fore storing the pumping unit. This is especially important if it ran more than 15,000 operating hours. 3. Close the suction and outlet lines, e.g., with the transport caps.
