Handling Mercury Overfill

  1. On the Manual Control window, open the reservoir evacuation valve. Evacuate for twenty seconds.

The Hg reservoir evacuated indicator should be displayed on the analyzer schematic. If it is not shown, do not proceed to the next step. Instead, verify that the mercury reservoir fill cap is properly sealed on top of the mercury filling funnel (see Maintain Mercury Level). If the Hg reservoir evacuated indicator still is not displayed, contact a Micromeritics Service Representative.

  1. Open the gas inlet valve. Close the gas inlet valve when at least 15 psia or atmosphere is attained.
  2. Open the mercury drain valve.
  3. Open the front panel of the analyzer and locate the Override switch on the small control panel.
  4. Press the switch. This allows mercury to drain back into the reservoir.
  5. Release the switch as soon as the pulsed buzzing stops. Close the mercury drain valve.
  6. Close the reservoir evacuation valve. If the pulsing tone remains, call the Micromeritics Service Department. The analyzer may be powered off.
