are you twisting? lifting upwards? pulling towards yourself?

I've tried all of those. Pulling in every direction and from every side.
I will contact Ventaxia and ask them..

Assuming it’s installed the right way up the front cover slides to the right then pull towards you , small plug in one end of the pcb is removed and rotated 180 degrees and refitted to adjust from low to high speed .

Thanks, but I have this manual. The instructions there are for the flat cosmetic front cover, not the main cover that contains the pcb

If you can’t simply lift off the cover the installers may have contaminated it with silicon , effectively glueing it in place .
