1. Cut hole in cabinet as well as holes in wall or floor as neces-
sary.
2. Mount the roof or wall cap and work back towards the cabinet,
attaching all ductwork, elbows and transitions as previously
planned. Tape all ductwork connections to make them secure
and air tight.
3. Connect ductwork (and transition, if required) to downdraft.
If necessary, LOOSEN nuts and screws that hold the blower
in place, and slide blower left or right to meet ductwork. Re-
tighten screws and nuts.
Note: A 3¼" x 10" collar (3¼" x 14" collar for external blower)
is provided for installers who prefer to rivet the ductwork to the
unit. This will allow blower to be removed and replaced easily in
service situations without disturbing ductwork.

2. Secure the downdraft to the countertop as follows: Hold the
downdraft against the back of countertop cut-out and tighten-
ing the two mounting screws (one on each end of unit) on
underside of countertop. Use a wood shim between screw
and underside of granite countertops.
3. Screw leveling brackets to bottom of cabinet. Tighten screws
holding leveling bracket to unit on each side.
