HOW TO USE YOUR QUIETCOOL

1.1 INTRODUCTION

CONGRATULATIONS
on the purchase of your new QuietCool Whole House Fan!
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. The difference between QuietCool and a standard whole house fan is a mix between its’ astounding energy efficiency and its’ jaw-dropping sound level. A standard whole house fan operates around 75dB; that’s equivalent to a loud vacuum cleaner running!
The QuietCool system uses a cutting-edge, patented design to get our sound levels down to a respectable level. Our fans suspend in the attic and use an acoustical duct that connects to a ceiling box and grille. The result is an easy installation and quiet operation.
Once the air outside is cooler than the indoor air, crack open a few windows, turn your QuietCool on, and enjoy the hot air being sucked out of your home and pushed out of your attic with a nice, cool breeze. While performing 15-22 complete air exchanges per hour, the QuietCool whole house fan system will force the hot stale air out of the attic which will help your house stay cooler during the hotter hours of the next day!

1.3 WHEN TO RUN THE QUIETCOOL WHOLE HOUSE FAN
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.

1.4 WHERE TO START COOLING THE HOME
We recommend cooling the area where you are going to be spending the most time for the next few hours. For example, in most family situations, the early evening is spent in the kitchen or family room area. Assuming this to be true, this is where you would want to start the cooling process. Begin opening a few windows in the area you are going to be spending your time and turn on all of your QuietCool fans at once, for maximum cooling. The cool outside air will immediately begin to create a breeze in the home making you instantly feel up to 10 ºF cooler. Opening windows too wide or opening too many windows will lessen the cooling breeze you feel.
The breeze will flow through your home and make its way to each QuietCool you have in operation. As it gets later in the evening, and even cooler outside, you can begin to open windows in other rooms of your home, to prepare for bedtime. Then when it’s time for bed, you should close all the windows in your main living space, but leave the windows in your occupied bedrooms open. This will provide each room with a cool breeze as long as desired.
Using the timer, you can automate your fan and have it turn off when you anticipate it being comfortable for sleeping. If you have a QuietCool installed in each bedroom as we recommend, you can enjoy the breeze and your privacy with your door closed.

1.5 HOW QUIETCOOL WORKS

1. Open a few windows anytime it’s cooler outside than inside, typically in the morning and evening.
2. Turn your QuietCool fan on by setting the speed and timer.
3. Quiet Cool pulls in cool, fresh air from outside and expels hot, stale air out attic vents.
4. Your home has now been made cooler, healthier, and more comfortable.

1.6 INDOOR AIR QUALITY
You will want to ventilate your home on a very regular basis. Many studies, such as one from the Environmental Protection Agency, show that the air inside a home can be 2-5 times more polluted than the air outside, even in the smoggiest of cities. Your QuietCool system can greatly reduce this problem by bringing in fresh air and exhausting stale polluted air. Even in the cold winter months, running your QuietCool for just a few minutes each day will allow you and your family to breathe happier and healthier.

1.7 USING QUIETCOOL DURING THE WINTER
During the winter, you can use the QuietCool to warm up your home during the warmer parts of the day.
Usually this occurs mid-day.
By running the QuietCool during the warmer parts of the day in the winter, you can heat up the thermal mass in your home so your heater doesn’t have to work as hard. This also allows you to purge your home of the old, stale air that accumulates in your home during the winter due to lack of opening windows.

2.2 SYSTEM VENTING REQUIREMENTS
VERY IMPORTANT: 1 SQUARE FOOT OF NET FREE VENT AREA PER 750 CFM
RECOMMENDED: 2 TO 4 SQUARE FEET OF INLET VENTS PER FAN
Venting plays a very significant role in the performace 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. If an attic has less than 1:750 attic venting, the system may not operate as efficiently, or effectively, as it could with 1:750 attic venting.
But don’t worry, the system will still operate if there is not enough venting.
Insufficient venting is a very simple problem to fix. Roofing contractors can add extra venting to most homes simply and easily. The most common types of venting is shown in the chart below.

http://qr.w69b.com/g/otELNGVrO

Installing the QuietCool system is very easy. Simply follow the steps given below:
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. Make sure you have a minimum of 30” of clearance. Take the cardboard cutout template and a small screwdriver with you. Make sure the template fits between the framing.

1. When you have chosen your exact spot, place the provided template on the spot and mark it at each corner by pushing the screwdriver through at each corner to make a hole so that you can find it from below.

2. 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.

3. Using a drywall saw or similar device, cut out the hole in the ceiling.

4. 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.

5. Take the main assembly, which includes the motor housing, damper box, and duct into the attic through the crawl hole and move into position near the ceiling cut-out hole.
   TIP: If your attic access is far from your fan location, you can remove the duct from the motor housing and pass the motor housing, duct, and damper box through the ceiling cut out hole and reattach the duct to the motor housing in the attic.

6. Pre-screw two wood screws into the rafter almost all the way. Usingthe new hanger strap with eyelet holes, hang the motor head from the two wood screws and tighten the screws. Make sure that the handy box on the motor head is at the very top. Secure duct to damper box using three black sharp screws. Make sure the housing is angeled slightly up and the duct has a gentle 90 degree bend to help reduce noise level. The angle is important so the fan does not disturb any blown-in insulation in your attic.
   NOTE: Once your QuietCool fan is hung, it’s time to go below and install the damper box and ceiling grille.
   NOTE: If you are installing the damper box with a vertical adapter, please follow the instructions on page 12.

7. 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. Do this along the entire edge of the flange and it will pop off.
   NOTE: The damper box flange is designed to sit on the backside of the drywall, inside the attic. Do not attempt to install the damper box with the flanges on the outer side of the drywall in the home.

8. Using the included drywall screws, fasten the damper box to both the drywall and the joist in the attic.
   NOTE: Remember that 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.

9. Remove ceiling grille and screws from its packaging. 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.

10. 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. The installation of the fan is now complete.
    NOTE: Do not install the QuietCool grille over a staircase, to prevent any risks during grille maintenance.
    NOTE: Some ceiling surfaces are uneven and may cause a small gap to be present. This can easily be caulked later if excessive.
    NOTE: Local building codes and standards must be adhered to in the installation of this unit.
    NOTE: Additional insulation can be added to the top of the damper box to provide additional sound dampening.
    NOTE FOR BUILDERS: When installing prior to sheetrock, the flange should be removed on all four edges, for both 24” and 16” on center to facilitate damper box exchange without damaging sheetrock. Damper box should be screwed to the bottom joists from inside the damper box, away from the doors and grille insert areas.

3.2 INSTALLING VERTICAL ADAPTER
A vertical wall adpater 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 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. If they are wider than 16” on center, you will only need to follow steps 1 & 4.
NOTE: The damper box MUST be installed with the damper doors oriented vertically. If the damper box is mounted on the wall with the damper doors horizontally, the damper doors will not operate correctly.

1. Note the T (TOP) side of the vertical adapter. Place the vertical adapter with the T side up onto the damper box with the side that has only two flanges, flush on the damper box.

2. If you have studs spaced at 16” on center, you will need to remove certain flanges on the damper box and vertical adapter. Using a flat head screwdriver, remove the two side flanges on the vertical adapter. (See Figure 3.2A)

3. Using a flat head screwdriver, remove the two side flanges on the damper box. Make sure that you are removing the flanges on the same side as the flanges you removed on the vertical adapter. (See Figure 3.2B)

4. Using the included black sharp screws, attach the vertical adapter to the damper box by screwing them together through the two remaining flanges.

5. The vertical adapter is now installed. Go back to step 8 on page 10 and continue your installation.

WIRING AND CONTROLS

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.
