    There is a short initialising routine, during which a beep sounds and all light elements light up briefly to confirm operation. Switch on the miVac Modular Concentrator and set the run type to “---” (no venting) see the miVac Modular Concentrator User Manual for details. The operation of the pressure controller may be erratic if alternative concentrator methods H2O (water) or –OH (alchohols) are selected.

  • Page 13: Changing The Control Parameters

    Pressure Controller Changing the Control Parameters The Pressure Controller must be inactive to allow access to the control parameter settings. Press the STOP key to deactivate the pressure controller. Select the required operating mode. See Selecting the Operating Mode for details.

  • Page 14: Changing The Pressure Set Point During Operation

    Take no action. The set point reverts to the previously set value when the STOP key is pressed. Additional Information The miVac Pressure Controller is not compatible for use with the H2O (water) and –OH (alchohols) run type settings of the miVac concentrator. This is because the concentrator controls the system vacuum using a timed pump venting sequence when these run types are selected.
