Hello, not a great design. I agree but the upper plenum has to be removed to get to the coils to access the plugs, They are blocked by the upper plenum as you know. I wish it was easier. I have included a couple files showing the repairs and this is why book time is as high as it is, see below , a copy from the manual

here are the links as well
