Page 8: Description
Section 1.3 for more information about gas-ballast. Your pump is water cooled. Edwards recommend that you use a thermostatic controlled valve to regulate water flow. This will ensure optimum pump working temperature, maintain economies in water use, and provide assistance with gas-ballast protection. - Page 9 1, item 1) open, when you switch the pump off, the pressure inside the pump will rise to atmospheric pressure. With the gas-ballast control closed, when you switch off the E2M175 and E2M275 pumps the vacuum will be maintained inside the pump.

Page 16: Installation
WARNING We do not recommend that you use the E2M175 and E2M275 pumps to pump hazardous substances. You must ensure that the pump is suitable for your application. If you have any doubt about the suitability of the pump for your application, refer to the Edwards guidelines on vacuum pump and vacuum system safety. -
Page 17: Unpack And Inspect
If you pump oxygen or other dangerous gases and vapours, you must use a chemically inert and stable oil (such as perfluoropolyether). For information on pumping dangerous gases and vapours, refer to the Edwards guidelines on vacuum pump and vacuum system safety (see Associated Publications at the end of the contents list). -
