  • It will go through its initial power on so don't expect the fans to start immediently.

  • If you have a message on the screen saying check filters you can clear it (once the filters have been cleaned) by:

    • Waiting until Normal airflow xx% is displayed on the screen

    • Press and hold the up and down arrows for 5 seconds

    • This will reset the cycle for the filter clean. Whenever you see the check filter message clean the filter (remember this is separate to the cell).

    • Keeping your MVHR cleaned to the Vent-Axia recommendations gives you the best chance of having many years of trouble free service.
