    • Remove any dead flies

  • Put the cover back on

  • Insert the screws and secure the cover to the MVHR.

  • Leave the internal and external filter out for now

    • We will slide them through the filter flaps later.

Kommentar hinzufügen

  • Insert the filters into each flap (clean if needed using a hoover)

  • Close the flap

Kommentar hinzufügen

  • Turn the heat recovery back on

  • 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.

Yes, this was an extremely useful guide. The maintenance manual simply says “withdraw the heat exchanger”, but it was as tight as a gnat’s a**e. Tom’s guide gave me the confidence to use a bit of gentle persuasion. Thanks :)
