DISCONNECT SWITCH BRACKET
FOR UNITS WITH OPTIONAL BELT-DRIVE BLOWER

A special bracket for mounting a field-supplied disconnect
switch is provided in each unit ordered with an optional
belt-drive supply air blower. The bracket is shipped inside the
blower compartment taped to the top of the blower housing.

Install the bracket on the left hand side of the unit as shown in
Figure 5. Several existing screws at the top of the unit and one
screw approximately midway down from the top will be used
for mounting the bracket. Screws should be loosened only -
NOT REMOVED. Matching holes in the bracket have
elongated keyways allowing easy installation. Re-tighten
screws after bracket is in place to ensure panels will remain
leak tight.
