5 MAINTENANCE
5.1 Introduction
The ESDP30A pump is designed to require little user maintenance. Do the following checks
when you maintain your vacuum system:
•
Check that the vacuum connections are secure.
•
Check that the electrical connections are secure and that the electrical cable is not damaged.
•
Check that the cooling-fins on the pump are not obstructed or blocked.
5.2 Inspect the inlet screen
Whenever you disconnect the pump from your vacuum system, we recommend that you:
•
Remove any debris trapped by the inlet screen (in the inlet-port).
•
Inspect the inlet screen and if necessary, clean it with a cleaning solution suitable for the
substances pumped. To remove the inlet screen, remove the circlip which secures the inlet
screen in the inlet-port. Refit the inlet screen in the inlet-port and secure with the circlip
before you reconnect the pump to your vacuum system.
5.3 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.
