5. Locate mounting holes in base pan.
6. Pre-drill the mounting holes in roof with 15/64"
bit with a drill gun using a depth gauge.
Do NOT drill without depth gauge to en-
sure bit does NOT penetrate cold air duct.
7. Match3″lagwithbondedsealingwasher.
8. Drivescrewusing9/16″socket.Finishinstalla-
tion with socket until base pan is lightly seated
on Dometic cubes. See (FIG. 30).
 Tighten mounting bolts to achieve
proper foam block compression. Overtightening
could damage unit’s base pan. Under tighten-
ing will allow an inadequate roof seal, and could
cause a leak.
Proper compression is achieved when
foam blocks compress to approximately
1-1/6″ so that Dometic cubes no longer
move freely beneath the base pan. There
should be slight resistance between Do-
metic cubes and base pan upon attempt-
ed removal of cubes.
