Install Support Bracket
1. Hold each support bracket flush against outside of sill and tight to bottom of cabinet. Mark brackets at top level of
sill. Mark cabinet bottom at distance of sill width. See Fig. 15 A. Remove support brackets.
2. Attach sill angle brackets to support brackets at marked positions with flat head bolts and nuts. Hand tighten only
at this point. See Fig. 15B.
3. Insert 1/2" long bolts through appropriate holes in cabinet bottom given the sill width distance. Thread the bolts into
the slots of the support brackets. Tighten lock washer nuts onto bolts.
4. Adjust height of sill angle bracket so that bracket rests securely on edge of sill, and so that cabinet has about 7/8" to
1 1/4" downward tilt for proper water drainage (tilted about 2° to 4° downward to the outside, see Fig. 14). Tighten nuts
securely. After proper installation, condensate should not drain from the overflow drain hole during normal use, correct
the slope otherwise.
