Page 23: Installation
You must ensure that the RV pump is suitable for your application. If you have any doubt as to the suitability of the RV pump for your application, refer to the Edwards guidelines on vacuum pump and vacuum system safety (see the Associated publications at the end of the Contents list at the front of this manual).
Page 24: Unpack And Inspect
The mass of the RV8 and RV12 pumps is approximately 26 kg. The RV3 and RV5 pumps have a lifting handle which you can use to move the pump by hand. If you wish to use mechanical lifting equipment, do not attach the equipment to the handle; for stability, use slings around the motor and the pump-body.

Page 26: Check The Direction Of Rotation
If the direction of rotation is incorrect, switch off the electrical supply immediately and contact your supplier or Edwards for advice. Page 20 © Edwards Limited 2007. All rights reserved. Edwards and the Edwards logo are trade marks of Edwards Limited.

Use a suitable valve to isolate the pump from your vacuum system if you need to pump condensable vapours or maintain vacuum when the pump is switched off. Ensure that sealing surfaces are clean and scratch-free. Page 24 © Edwards Limited 2007. All rights reserved. Edwards and the Edwards logo are trade marks of Edwards Limited.
Page 31: Leak-Test The System
Leak-test the system and seal any leaks found after you have installed the RV pump, to prevent leakage of substances out of the system and leakage of air into the system. © Edwards Limited 2007. All rights reserved. Page 25 Edwards and the Edwards logo are trade marks of Edwards Limited.
Page 33: 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 2007. All rights reserved. Page 27 Edwards and the Edwards logo are trade marks of Edwards Limited.
Page 34: Gas Purges
If liquids that produce flammable vapours could be present in the pump foreline, then the inert gas purge to the RV3, RV5, RV8 and RV12 rotary vane pump should be left on all the time this liquid is present. Flammable liquids could be present in the foreline as a result of condensation, or may be carried over from the process.
Page 35: Mode Selector
Where possible, we recommend that you select low flow gas-ballast (position ‘I’) rather than high flow gas-ballast (position ‘II’) to minimise the loss of oil. © Edwards Limited 2007. All rights reserved. Page 29 Edwards and the Edwards logo are trade marks of Edwards Limited.
Page 36: Start-Up Procedure
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, see below) must be much lower than the specified ultimate vacuum of the pump.
Page 37: To Pump Condensable Vapours
If necessary, change the mode selector to High Throughput mode and reduce the thermal load from the pumped gases, to prevent overheating of the pump. © Edwards Limited 2007. All rights reserved. Page 31 Edwards and the Edwards logo are trade marks of Edwards Limited.

4. On single-phase pumps, use the on/off switch to switch off the pump. 5. Switch off the electrical supply to the pump. Page 32 © Edwards Limited 2007. All rights reserved. Edwards and the Edwards logo are trade marks of Edwards Limited.
Page 39: Maintenance
Data Sheets for fluorinated materials used in the pump are available on request: contact your supplier or Edwards. If necessary, maintain the motor as specified in the manufacturers information supplied with the motor. © Edwards Limited 2007. All rights reserved. Page 33 Edwards and the Edwards logo are trade marks of Edwards Limited.
Page 40: Maintenance Plan
If necessary, adjust the maintenance plan according to your experience. When you maintain the RV pump, use Edwards spares and maintenance kits; these contain all of the components necessary to complete maintenance operations successfully. The Item Numbers of the spares and kits are given in Section 7.3...
