1. SYSTEM OVERVIEW WELCOME 1.1 INTRODUCTION CONGRATULATIONS on the purchase of your new QuietCool Roof Mount Whole House Fan! INSTALLATION The QuietCool Roof Mount Fans offer great versatility for any system you are looking to put in. QuietCool Roof Mount Fans can be used in many applications such as a whole house fan with a duct, or as a whole house fan that pulls air through air intake grilles in multiple rooms.
1.3 SYSTEM VENTING REQUIREMENTS ! ! VERY IMPORTANT: 1 SQUARE FOOT OF NET FREE VENT AREA PER 750 CFM Vent Type RECOMMENDED: 2 TO 4 SQUARE FEET OF INLET VENTS PER FAN Venting plays a very significant role in the performance of QuietCool fans. QuietCool recommends a minimum of 1 SQ. FT. of venting 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.
READ BEFORE ATTEMPTING TO INSTALL AN RM FAN ! WELCOME GETTING STARTED NOTE: Always follow local building codes because the fan may require specific fasteners or anchoring systems not discussed in this installation guide. Installation should be done by a licensed roofing contractor. GENERAL SAFETY INFORMATION INSTALLATION 1. READ INSTRUCTIONS - All safety and operation instructions must be read. 2. RETAIN INSTRUCTIONS - The safety and operating instructions should be kept for future reference. 3.
2. INSTALLATION 2.1 INSTALLING THE RM WHF-4.0 Installation Video: Watch the video by scanning the QR code or visit www.QuietCoolSystems.com/support 1. Determine in which area you would like to install your QuietCool Roof Mount Fan (see diagrams below) 24” on center 16” or 24” on center 24” on center 16” or 24” on center 16” or 24” on center 24” on center 16” or 24” on center 2.
! WELCOME 3. From inside the attic, find the center point between the two roof rafters and mark it as the center of the fan hole. Partially insert a screw into the center point mark. NOTE: If you have a tile roof, you will need to move tiles out of the way before tracing and cutting. 4. Go to the roof. Using the screw as a reference point and the provided template, trace out the 22” diameter circle. 5. Use a reciprocating saw to cut out the traced hole pattern from the roof decking.
Shingle Roofs: 12. If you have a shingle roof, insert the reciprocating saw sideways between the shingles and roof decking. Starting at the 3 o’clock position of the vent hole, begin cutting in a sweeping motion under the shingles, cutting through any roofing nails or staples. Continue cutting counter-clockwise around the vent hole until reaching the 9 o’clock position.
Figure 2.2B WELCOME 2. Determine the location for your damper box. Ensure that the duct will fit with an adequate bend. 3. Go up into the attic to mark the exact location for the damper box. Take the cardboard cutout template and a small screwdriver with you. Make sure the template fits between the framing. 5. From below, place the cutout 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.
! IMPORTANT: You must fasten the damper box to the ceiling joists AND drywall. The purpose of this is to make sure the damper box stays in place when you are screwing in the grille. If you do not fasten the damper box to the drywall, the damper box will not stay in place when attempting to screw in the grille. 10. Center the grille over the damper box. Install the grille with the white screws provided by screwing through the drywall into the flange of the damper box. (See Figure 2.2I) ! Figure 2.
2.4 INSTALLING THE RM WHF-4.0-DG2 WELCOME Use the following instructions to finish the installation of your accessory kit. These instructions are for installing the RM WHF-4.0 with (2) 16” x 16” damper grilles. 1. Using a stud finder, find and measure your ceiling joists and determine the location for your damper grilles. Make sure the fan is equally centered between the two damper grille locations. Make sure the damper grilles are installed in the same joist bay as the fan. INSTALLATION 2.
2. Secure the Flash Mount to the roof. Finish sealing around the Flash Mount and flash it into the roof to make a nice seal. If using peel and stick to flash the flash mount, be sure to not apply too high on the flash mount so it does not interfere with the plenum box when sliding the box over the flash mount. (See Figure 2.5C) Take the plenum box and slide the Flash Mount lip into the plenum box. (See Figure 2.5D) 3. Adjust the plenum box legs to position the plenum box properly on the roof.
Figure 2.5M ! WELCOME NOTE: The Plenum Box includes a weatherproof EMT compression connector. The connector is installed to the plenum box in the proper orientation to run electrical piping directly into the plenum box, however, you can also swap the connector around if you want to install a weatherproof junction box.
3. WIRING ! ! ! IMPORTANT: Wiring Diagrams are for examples ONLY. Wiring should be done by a licensed electrician following local building and electrical codes and/or NEC guidelines. NOTE FOR BUILDERS: Where use of arc-fault breakers are 100% implemented in the home, or if the whole house fan is installed in a wet area such as a bathroom, wiring a dedicated circuit may be required. NOTE: Your fan came with the RF Hub pre-wired to a power cord for testing purposes before installation.

HOW DOES RF WORK? A small electronic device is used to transmit and/or receive radio signals between two devices. In an embedded system, it often communicates with another device wirelessly. This wireless communication may be accomplished through optical communication or through radio frequency (RF) communication. WILL RF INTERFERE WITH OTHER DEVICES IN MY HOME? The RF will not interfere with other wireless or RF devices in your house.
4.3 WHEN TO RUN A QUIETCOOL WHOLE HOUSE FAN WELCOME 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.
