Page 16: Check The Direction Of Motor Rotation
Step 1 to ensure that the direction of rotation is now correct. • On a 1-phase pump, do not use the pump. Contact your supplier or Edwards for advice. Connect the pump-inlet to the vacuum system Ensure that debris does not get into the pump when you install it. If the pump is to replace a pump in an existing system, purge the existing pump with nitrogen for 15 minutes before you disconnect it. -

Note: When you switch off the pump, the cooling-fan may stop and then rotate in the reverse direction for a few revolutions. Use the procedure below to shut down the pump. 1. Close the vacuum system isolation-valve (to prevent suck-back into the vacuum system). 2. Switch off the electrical supply to the pump. ESDP30A Scroll Pump... -
Page 19: Maintenance
Service We recommend that the ESDP30A pump is serviced by Edwards service engineers at least once a year (if the pump is in continuous use) or every 8500 hours of pump operation; contact your supplier or Edwards to arrange these services. -
