Coleman Mach 15 Ducted Grill

[Lawsoncb]

Recently had my AC replaced with a Coleman Mach 15. The lower grill is very does not seem to be securely installed.

I took it apart to clean filter and the grill is attached with screws directly to ceiling with one screw angled severely to attach to the metal frame. The other three are really loose and I have to move them around to find new places to attach them to get them to hold.

Is this the correct insulation?

The screws should screw into the metal mounting ring, not at an angle but straight up into mounting ring per installation manual. I have seen some into the ceiling but they are not very secure and the screws hole strip out easily. Look at the mounting ring on the ceiling and see if the grill will line up if the grill is turned 90 degrees. The Coleman's I've worked on cleaning condenser coils, fan motor replacement etc. all attached to the mounting ring. But I could be wrong on this one though. Hope this helps.

If nothing else, get some small strips of wood and glue to the ceiling fabric on the upper side of the fabric. This will give better support to the grille and something for the screw to bite into. I did this with the small return grilles on my Suites--worked very well.
Just running a screw into soft material doesn't give us a warm, fuzzy feeling, eh?
