Installation Instructions

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

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)

2 - Mounting Brackets

1 - Mounting Flange

4 - 10-32 Nuts

1 - Instruction/Safety Sheet

2.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. This fan will require at least 10" of clearance in the ceiling or wall, and will mount through drywall up to 3/4" thick.

3. Select the most convenient electrical knockout and remove using a straight- blade screw driver (Figure 1).
