Grille 1-3 When to Run the QuietCool Whole House Fans Anytime it is cooler outside than the inside of your home, the system will work effectively. In the summer this normally happens in the late afternoon to early evening, through to the next morning. We recommend running your fan through the evening. If you have a multi-speed fan, you will get the best cooling effect when you turn the fan on low after desired cooling occurs and let it run throughout the night.
2. SYSTEM OVERVIEW 2-1 INTRODUCTION Congratulations on the purchase of your new QuietCool system! The QuietCool whole house fans dominate the market in energy efficiency and quietness. Whole house fans operate by pulling the cool air from outside your home, through the living space, into your attic, and out your attic vents. This accomplishes a cooling effect that can save you up to 90% off your A/C related energy costs depending on where you live.
2-3 System Venting Recommendation FOR OPTIMAL PERFORMANCE! - 1 SQUARE FOOT OF NET FREE VENTING PER 750 CFM Venting plays a very significant role in the performace of whole house fans. QuietCool recommends a minimum of 1 SQ. FT. for every 750 CFM in the QuietCool system. If an attic has at least 1:750 attic venting, the QuietCool system will operate efficiently and effectively.
3. INSTALLATION TOOLS YOU WILL NEED - Drywall saw 3-1 - Phillips screwdriver - Pencil - Power-drill - Philips bit Installing QuietCool NOTE: Be sure to plug in your fan before attempting to install to ensure that the fan is operational and the fan blade spins freely. Installing the QuietCool system is very easy. Simply follow the steps given below: 1. Determine from down below in which areas you would like to install your QuietCool fan. Go up into the attic to mark the exact location for the fan.
3. From below, place the cut-out template on the ceiling, making sure that you have at least 2 inches of clearance all around it. While holding the template in place, mark its outline with a pencil. 4. Using a drywall saw or similar device, cut out the hole in the ceiling. 5. Open and unpack your QuietCool fan. TIP: If your attic is very tight, you may want to wire your QuietCool motor housing before bringing it into the attic. Please follow the wiring diagrams that start on page 13. 6.
NOTE: If you are installing the damper box with a vertical adapter, please follow the instructions on page 12. 8. Look through the hole and make sure there are no kinks or twists in the ducting. Pull the damper box down through the hole in the ceiling. NOTE: The QuietCool Damper Box includes removable flanges in the case that you are installing the damper box between studs that are exactly 16” on center. To remove the flanges, simply take a screwdriver and pry between the flange surface and the damper box.
insert back in place, simply push it right into place, and it will snap in tight. NOTE: Some ceiling surfaces are uneven near the grille and may cause a small gap to be present. This can easily be caulked later if excessive. 11. Return to the attic. Using the nylon straps and the long wood screws provided, support the duct to the framing. This will stabilize the entire assembly. Replace any insulation that was removed. Make sure the duct is hanging at a nice 90 degree angle.
3-2 Installing Vertical Adapter (vertical adapter models shown on page 8) A vertical wall adapter allows a damper box to be installed in the wall instead of the ceiling. A vertical adapter is installed on the wall with the damper box mounted diagonally to the wall so the damper doors close properly when the fan is turned off. NOTE: Measure the studs in your wall. If they are 16” on center, you will need to follow steps 1 through 4 completely.
4. WIRING NOTE: Wiring Diagrams are for examples only and wiring should be done by an experienced electrician. 12 or 14-gauge romex is common. Check your local building code before choosing the wire type. 4-1. Single Speed Wiring For wiring of the STL PRO-1.5X with one speed. 4-2.
