1. 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
efciency 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 efciency 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!

Turn your QuietCool fan on by setting the speed and
timer.
Your home has now been made cooler, healthier, and
more comfortable.
Open a few windows anytime it’s cooler outside than
inside, typically in the morning and evening.
QuietCool pulls in cool, fresh air from outside and
expels hot, stale air out attic vents.
1.5 HOW QUIETCOOL WORKS
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 recom-
mend 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 ow 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.

Your home has now been made cooler, healthier, and
more comfortable.
QuietCool pulls in cool, fresh air from outside and
expels hot, stale air out attic vents.
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.
If you have any trouble installing or operating your new QuietCool whole house fan, or for
more tips on running the QuietCool, please visit our website
www.QuietCoolSystems.com or call us at 951-325-6340 for support.
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 signicant 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 efciently and effectively. If an attic has less than 1:750
attic venting, the system may not operate as efciently, 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.
Insufcient venting is a very simple problem to x. Roong contractors can add extra venting to most
homes simply and easily. The most common types of venting is shown in the chart below.

3. INSTALLATION
3.1 INSTALLING STEALTH PRO X WHF
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 ts between the framing.
1. Open and unpack your QuietCool fan.
2. 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
nd it from below.
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.
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. Using
the keyholes on the straps, 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
the duct clasps. 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.
