Use an inert gas purge into the pump gas ballast connection to prevent the condensation of flammable  vapours within the pump mechanism and exhaust pipeline. © Edwards Limited 2012. All rights reserved. Page 19 Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 26: Gas Purges
When you operate the pump with the gas-ballast control open, there will be an increased rate of oil loss from the pump. Ideally, a mist filter and oil return kit should be used on clean applications.

Page 27: Start-Up
2.2, make sure that this is not due to your system design before you contact your supplier or Edwards for advice, In particular, the vapour pressure of all materials used in your vacuum system (including pump oil, refer to below) must be much lower than the specified ultimate vacuum of the pump.
Page 28: To Pump Condensable Vapours
2. Close the vacuum system isolation-valve (if not already closed). 3. Close gas-ballast (that is, turn the gas-ballast control clockwise). 4. Switch off the electrical supply to the pump.
