TOP GRILLE OR FAN MOTOR MOUNT ADJUSTMENT FOR FAN CLEARANCE

Sometimes during shipping, either the fan motor mounting or top grille may become out of alignment. This may cause the
fan motor blade to not clear the orifice ring. If this situation occurs, simply adjust either or both the fan motor mount or top
grille positions to allow proper clearance. The top grille four fastener insertion points to the plastic top and motor mount
locations are larger than the fasteners used to secure the grille and fan motor mounts. Use the procedures provided in figure
37 to adjust for fan clearance.

The four mounting point holes that secure the top grille to the
plastic top are larger than the fasteners used to secure the grille.
this is also true for the four fasteners securing the fan motor to
the top grille. To provide more clearance, preform either or both
of the following procedures.

TOP GRILLE ADJUSTMENT

loosen the four grille mounting fasteners and push the grille
forward. tighten mounting hardware. if there is still insufficient
clearance proceed to Fan Motor Position Adjustment.

ORIFICE RING

FAN MOTOR POSITION ADJUSTMENT

Loosen the four fan motor grille mounting fasteners and push the
fan motor forward. tighten mounting hardware.
