SECTION 1

Preparing the Exhaust Fan

1.Unpack fan from the carton and confirm that all pieces are present. In addition to the exhaust fan you should have:

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.

Figure 4

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).

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

Ducting

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL AND NATIONAL BUILDING CODES.

1.Connect the ducting to the fan’s duct collar (Figure 6). Secure in place using tape or screw clamp. Always duct the fan to the outside through a wall or roof cap.

Wiring

CAUTION: MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE STARTING INSTALLATION.

CAUTION: ALL ELECTRICAL CONNECTIONS MUST BE MADE IN ACCORDANCE WITH LOCAL CODES, ORDINANCES, OR NATIONAL ELECTRICAL CODE. IF YOU ARE UNFAMILIAR WITH METHODS OF INSTALLING ELECTRICAL WIRING, SECURE THE SERVICES OF A QUALIFIED ELECTRICIAN.

1.Run wiring from an approved wall switch carrying the appropriate rating. One neutral (white), one ground (green or bare copper), and one hot (black lead connected to the switch). Secure the electrical wires to the housing with an approved electrical connector. Make sure you leave enough wiring in the box to make the connection to the fan’s receptacle.

2.From where you have access to inside the fan’s junction box, connect the White wire from the house to the White wire from the fan’s receptacle. Connect the Black wire from the wall switch to the Black wire from the fan’s receptacle. Connect the ground wire from the house to the Green wire from the fan’s receptacle (Figure 7). Use approved methods for all connections.

SECTION 6

Completing the Installation

1.Reinstall the fan’s wire compartment cover. Rotate the blower wheel by hand to ensure it spins freely. Plug the fan’s quick connect motor cord into the receptacle. This cord will only fit one way into the receptacle (Figure 8).

Figure 8

2.Install the grill by squeezing the two ends of the springs together and installing them up into the slots of the fan’s housing. Push the grill up into position (Figure 9).

Figure 9

3. Restore power and test your installation.
