against the frame rib. Transfer the two bracket
mounting holes to the frame. Using a .281dia. drill
bit, drill the two holes through the damper frame.
2. Remove the switch cover and attach the electrical
wires to the appropriate terminals of the switch.
Reassemble the cover to the switch. Make sure
the wires do not short each other. Tighten the
screws that hold the switch and cover to the
bracket.
3. Attach the switch bracket to the frame using
the supplied screws and nuts. Make sure the
switch bracket is pushed against the frame rib,
then tighten the fasteners. Cycle the switch lever
to make sure that it clears the frame ribs and
operates freely. If interference detected, bend the
switch lever or reposition the moutning bracket.
