Page 9: Description
The distributor valve provides only oil suckback protection when you switch off an E1M40 or E1M80 pump. To obtain air suckback protection when you switch off an E1M40 or E1M80 pump, you must fit a solenoid operated gas-ballast control valve:...
Page 10 With the gas-ballast control closed, when you switch the pump off: E1M40 and E1M80: the pressure inside the pump will slowly rise to atmospheric pressure. (To maintain the vacuum inside the pump, fit a solenoid operated gas-ballast control valve.) E2M40 and E2M80: the vacuum will be maintained inside the pump.

Page 17: Installation
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. (See Associated Publications at the end of the contents list).
Page 18: Unpack And Inspect
If the pump is not to be used immediately, replace the protective covers. Store the pump in suitable conditions, as described in Section 6.1. Page 12 © Edwards Limited 2007. All rights reserved. Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 19: Locate The Pump
When the ambient temperature is 12°C or higher, we recommend that you use Edwards Ultragrade 70 oil. This tested and proven oil will give you the best performance, maintenance intervals and pump life. Otherwise, use another oil with the specification VG ISO 68.

Page 27: Operation
A344-02-880 Issue J Operation WARNING We do not recommend that you use the E1M40, E2M40, E1M80 and E2M80 pumps to pump hazardous substances. Gas-ballast control Use the gas-ballast control (Figure 1, item 11) to change the amount of air (or inert gas) introduced into the low-vacuum stage of the pump.
Page 28: To Achieve Ultimate Vacuum
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, must be much lower than the specified ultimate vacuum of the pump.
Page 29: Unattended Operation
2. Close the vacuum system isolation-valve (if not already closed). 3. Turn gas-ballast control (Figure 9, item 4) clockwise to close. 4. Switch off the electrical supply to the pump. © Edwards Limited 2007. All rights reserved. Page 23 Edwards and the Edwards logo are trademarks of Edwards Limited.
