Hi,

THANKS for the help. I didn't realize that the grill was removable,
figured that it was welded to the housing. Got mine out by just taking
the plastic screws out above it, loosing the 6 bolts, and I was able to
slide it out the top. It was a tight fit but sure beats lowering the
unit.

The screw came out of the latch like a dream. I used a driver bit and it
did the trick.

Thanks again
michael
