SECTION 1

Preparing the Exhaust Fan

1 - Grill

1 - Damper Assembly (attached)

1 - Mounting Bracket

1 - Hardware Bag

1 - Electrical Connector

3 - Wire Nuts

1 - Instruction/Safety Sheet

2.Snap the fan body into the bracket (Figure 4). The fan can be snapped into position with the duct collar facing to the left or the right depending which is most convenient.

SECTION 3

Existing Construction

2.Remove the wire compartment cover and store in the carton until needed so it does not get damaged or lost (Figure 1).

Figure 1

3.Choose the location for your fan. To ensure the best air and sound performance, it is recommended that the length of ducting and the number of elbows be kept to a minimum, and that insulated hard ducting be used.

Larger duct sizes will reduce noise and airflow restrictions.

4. Select the most convenient electrical knockout and remove using a straight-blade screw driver (Figure 2).

SECTION 2	Figure 2
New Construction

1.Using the gauge on the mounting bracket, line up the bracket on the joist so the bottom of the fan will be flush with the finished ceiling. Nail or screw the bracket in place securely (Figure 3).

1.Position housing against the joist or stud and trace an outline of the housing onto the ceiling/wall material. Set housing aside and cut opening, being careful not to cut or damage any electrical or other hidden utilities (Figure 5).

2.Line up the bracket on the joist so the bottom of the fan will be flush with the finished ceiling. Nail or screw the snap-in bracket in place securely (Figure 3).

3.Snap the fan body into the bracket (Figure 4). The fan can be snapped into position with the duct collar facing to the left or the right depending which is most convenient.

SECTION 4
