    • 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.

결론

Your heat cell is now clean. Vent-Axia recommend you clean the cell once a year.

Remember to clean your filters as needed. If you want any extra information all appropriate manuals are attached to this guide.

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 :)

Hi

I followed this great guide on a vent axia unit installed in a council property,the arrows however did not correspond I.e black to black red to red before I extracted the cell.Has it been incorrectly installed all this time(10 years)?Which way around do I insert it now?

the same as he was removed (or in the correct way). it’s your choice

As far as I know the arrows are there to note which way round the installer decided to fit the unit. If you were to take the back off on my unit the other side would have red arrows. I don’t know what the impact would be but as long as the ducting is connected properly I doubt it would be a huge problem. You could ask Vent Axia support, they are very helpful. Its been going strong for 10 years so it can’t be that bad!

In terms of the correct way round I would say arrow to arrow should be fine. I assume that’s the way you took it out?
