WHERE TO LOCATE Whole House Fans are designed to pull in fresh, cool air from the outside through open windows in your home. Hot air that is in the home is pulled up through the fan and into the attic, and then exhausted through vents in the roof, under eaves, soffits or gables. STEP 1: SELECT THE INSTALLATION SITE 1. The unit is designed to be installed on the floor of the attic between the joist that are a minimum of 16" on center. Most modern homes are built with either 16" or 24" on-center (OC) joists.

INSTALLATION 1. **Warning: Cut out drywall to the dimensions of the Grille and not to the dimensions of the metal damper box.  From inside the attic at your predetermined location drill two holes at the edge of the joist approximately 12 inches apart.  From inside the home use the two newly drilled holes as a guide to align the inner edge of the grill and outline with a pencil.  Using a drywall saw or similar tool, cut out the drywall.

3. Installing Damper Box  Attach the supplied brackets to the joist as shown in the picture below using the 1 ½” hex screws.  Place the damper box on top of the brackets as shown in the picture below and screw one side of the damper box to the joist. The brackets will support the weight of the damper box.

4. Attaching the Ducting ***IMPORTANT*** DO NOT stretch ducting tight from end to end, as this could cause the tape securing the ducting to the metal collar to pull away over time. However, you do want to use the full length of the ducting while leaving a little slack to get the quietest operation. Place one end of the duct collar over the fan shroud and secure with at least four of the selftaping screws evenly spaced around the shroud. .

 Using the black nylon strap hang the ducting from the rafters with 1 ½” hex screws and flat washers. Note: For quietest operation it is best to get a 90 degree bend in the ducting.  Place the other end of the duct collar over the damper box and secure with the supplied self-taping screws.

5. Installing Grille  Install the grille over the opening and secure with the four grille screws provided. 6. Remote Control Operation  Plug the electrical cord from the fan housing into the remote control outlet Note: if you do not have an electrical outlet in your attic you will need to install one. Be sure to have a licensed electrician install all electrical wiring. Failure to have a professional install electrical wiring could result in injury or death. 7.

REQUIRED VENTING AREA For proper operation of your Comfort Cool whole house fan, it is CRITICAL that your attic has sufficient venting area; otherwise the hot air cannot easily escape and creates back-pressure that can substantially reduce the performance of your new whole house fan. The “net-free” area of a vent is the total vent opening minus the loss caused by the interference of the screen, louver or grille covering the vent.  The Centric Air 1.5 requires a MINIMUM of 1.5 sq. ft.
