  • Page 36: Mode Selector

    When using either low flow or high flow gas-ballast, there will be an increased rate of oil loss from the pump. Where possible, we recommend that low flow gas-ballast (position ‘I’) is selected, rather than high flow gas-ballast (position ‘II’), to minimise the loss of oil. A65201880_AA Page 36 03/2021 - ©Edwards Limited...

  • Page 37: Start-Up Procedure

    Turn the mode selector to select High Throughput mode S , set the gas-ballast control to low flow (position ‘I’) and operate the pump for at least 1 hour (or overnight) to thoroughly purge the oil of contaminants. A65201880_AA Page 37 03/2021 - ©Edwards Limited...

  • Page 38: To Pump Condensable Vapours

    If necessary, change the mode selector to High Throughput mode S and reduce the thermal load from the pumped gases, to prevent overheating of the pump. A65201880_AA Page 38 03/2021 - ©Edwards Limited...

  • Page 39: Shut-Down

    Close the vacuum system isolation-valve (if not already closed). Close gas-ballast (set the gas-ballast control to position ‘0’).
