Page 27: Connect The Pump Outlet
Remove the outlet nozzle and replace it with an NW25 flange adaptor (available as an optional accessory, refer to Section 7.4.13) and then connect to the NW25 flange. © Edwards Limited 2011. All rights reserved. Page 21 Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 28: Gas-Ballast Inlet Connection
Leak-test the system and seal any leaks found after you have installed the pump, to prevent leakage of substances out of the system and leakage of air into the system. Page 22 © Edwards Limited 2011. All rights reserved. Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 29: Operation
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 2011. All rights reserved. Page 23 Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 30: 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 31: 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 32: 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.

Page 33: Maintenance
The pump may have overheated if it was misused, if it malfunctioned or if it was in a fire. Edwards Material Safety Data sheets for fluorinated materials used in the pump are available on request: contact your supplier or Edwards.
Page 34: Check The Oil-Level
Repeat this step until the oil reservoir is clean. 6. Refit the oil drain-plug, remove the block and reconnect the pump to your vacuum system. Page 28 © Edwards Limited 2011. All rights reserved. Edwards and the Edwards logo are trademarks of Edwards Limited.
