Answered AC access

How do you open this access panel?

 

[Neal]

One side is hinged. Once you determine that, pull down the other side. It can be hard as it uses strong magnets.

Thanks, @Neal those are some tough magnets, all good now

There is an L shaped tool, like wire hanger material. Use that to open the panel. Insert in openings on pass side, turn and pull down

While open we cleaned the black filters on the inlet side every two months.

Actually bought another set at the mothership and just replaced them then cleaned and stored spares until next time.
