Shut-down

Edwards recommends, as described in the following procedure, decontaminating the oil before shutting down the
pump; this will prevent damage to the pump by the contaminates in the oil.
1. Refer to Section 4.6 and decontaminate the oil, as required.
2. Close the vacuum system isolation-valve (if not already closed).
3. Close gas-ballast (set the gas-ballast control to position '0').
4. On single-phase pumps, use the on/off switch to switch off the pump.
5. Switch off the electrical supply to the pump.
