How do I reset the service mode on the ProMist 75 and 100 pumps?

When the pump's total running time reaches 300 hours, the maintenance icon displays and the alarm sounds. This status does not stop normal operations of the pump, but it is highly advised to perform maintenance at this time.

Please review the entirety of the following instructions before beginning.

To reset the maintenance notification:

  1. When the machine is standing by, press and hold the (MODE) button and the (TEMPERATURE) buttons at the same time for 3 seconds, then the system enters into service mode.
    • While in service mode, the system automatically returns to normal mode if no buttons are pressed for 15 seconds.
  2. Press the (ENTER) button to cycle through service modes 1, 2 & 3. The mode will be displayed in the top left corner of the screen.
    1. Go to mode 2.
    2. Press and hold the (DOWN) button for 3 seconds.
    3. Maintenance notifications are now reset.
  3. To return the system to normal operation, you may press the (MODE) button or wait 15 seconds for service mode to time out.
