1. SYSTEM OVERVIEW
1.1 INTRODUCTION
CONGRATULATIONS
on the purchase of your new QuietCool Smart Attic Fan!
QuietCool Attic Fans are the best in the business. New for 2020,
our Smart Line of attic fans have gotten even smarter! Now through
the use of a smartphone app, you can control all the settings of your
Smart Attic Fan right from your couch!
With the QuietCool Smart Control App, you can see your current
attic temperature and humidity, modify the temperatures for the
multiple speeds of the fan, setup presets for the different seasons of
the year, and even operate your fan on a timer!
QuietCool Attic Fans work almost everywhere, anytime. During the
summer, an attic can be 40-50 degrees hotter than the outside tem-
perature, which in turn heats up the house much faster. With an attic
fan, you can cool the attic to the same temperature as it is outside,
greatly reducing the house from heating as quickly.

1.3 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 mini-
mum 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.
Vent Type Model Type Average Size Venting Sq. Ft.

READ BEFORE ATTEMPTING TO INSTALL AN AFR FAN
GETTING STARTED
NOTE: Always follow local building codes because the fan may require specic fasteners or
anchoring systems not discussed in this installation guide. Installation should be done by a
licensed roong contractor.
GENERAL SAFETY INFORMATION
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. HEED WARNINGS - All warnings should be followed.
4. FOLLOW INSTRUCTIONS - All installation and operating instructions should be followed.
5. WATER - The QuietCool system should not be used near water. If you live in a very humid climate,
be sure to cover your damper box with insulation to reduce condensation.
6. HEAT - The QuietCool system should be situated away from heat sources.
7. DAMAGE REQUIRING SERVICE - Only qualied service personnel should service the QuietCool system.
The user should not attempt to service the product.
8. SAFETY PRECAUTIONS -
+ Do not install the fan in wet or windy conditions
+ Tie-off both yourself and your equipment when working on steep pitched roofs to avoid falls
+ Wear safety glasses and protective gloves when using power tools
+ Always wear slip-resistant shoes when working on the roof
+ Do not cut through any rafters or structural members of the roof during installation
TOOLS YOU WILL NEED
+ Cordless Drill with Nut Driver
+ Roong Nails
+ Measuring Tape
+ Reciprocating Saw
+ Weatherproof Roong Grade Sealant
+ Roong Knife
+ Carpenter Pencil
+ Flashing Material (If Needed)
CHOOSING THE RIGHT LOCATION
(MAX ROOF PITCH - 9/12)
Choose a location to install your QuietCool roof mounted fan that allows for balanced airow throughout the
attic space. We always recommend the fan to be installed centrally located on the roof three feet below the
ridge line. This will allow you to access the fan very easily. Your roof mount fan should not be installed any
closer than within 5 feet to an existing passive vent, ridge vent, or additional fan unit.
IMPORTANT: Do not cut through any rafters or structural members while cutting the fan hole.
Only cut out the roof decking.

2. INSTALLATION
2.1 INSTALLING AFR
1. Determine in which area you would like to install your
QuietCool AFR.
2. From inside the attic, nd 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 the
tiles out of the way before tracing and cutting. (See Figure
2.1A)
3. Go to the roof. Using the screw as a reference point and the
provided template, trace out the 16” diameter circle.
4. Use a reciprocating saw to cut out the traced hole pattern
from the roof decking. Remove the cut out decking material
from around the hole as needed. (See Figure 2.1B)
5. 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 fan hole, begin cutting in a
sweeping motion under the shingles, cutting through any
roong nails or staples. Continue cutting counterclockwise
around the fan hole until reaching the 9 o’clock position. Using
a roong knife, cut a 4 inch horizontal slit in the shingles at the
9 o’clock and 3 o’clock positions of the hole, allowing the fan’s
ashing to slide underneath the shingles.
6. Apply weatherproof material to the roof. (See Figure 2.1C)
7. Position the fan so that it is centered with the fan hole and
allow the power cord to hang freely from the bottom of the
fan unit. The power cord comes in 20 ft length.
(See Figure 2.1D)
NOTE: Power cord CANNOT be used outdoors.
8. Lifting the fan unit up at an angle, apply weatherproof caulking
to the bottom side of the fan unit. This will help keep the fan in
place and will seal nice and tight.

NOTE: Wiring Diagrams are for examples ONLY. Wiring should be done by an
experienced electrician.
NOTE: Your fan came with the Smart Control Hub pre-wired to a power cord for testing purposes
before installation. If you would like to hard-wire the fan, or it is required by your local building
codes, please follow the wiring instructions below.

Secure the fan ashing to the roof. Finish caulking
around the fan and ashing it into the roof to make
a nice seal. (See Figure 2.1E)
10. If installing on a tile roof, cut tile appropriately
and re-install the tile to t snuggly around the fan
housing. (See Figure 2.1F)

4.3 FREQUENTLY ASKED QUESTIONS
WHAT PROTOCAL DOES THIS CONTROL USE?
This control operates over Bluetooth to connect to your phone. The control uses Wi-Fi for rmware
updates.
WILL MY NEIGHBOR BE ABLE TO CONTROL MY FAN IF THEY HAVE THE SAME
SET UP AS ME?
No. In order to connect to your Smart Attic Fan Control Hub, you must rst pair your device by
using the Pair button on the Hub.
WHAT IS THE RANGE?
The range restriction between your phone and the attic fan is 50 ft through average household
obstructions.
WHY ARE ALL MY LIGHTS BLINKING ON THE HUB AND NOTHING IS
WORKING?
If you’re experiencing blinking lights on all LED indicators on the hub then it is an indication that
your DIP switches are not selected, or multiple DIP switches are selected. Disconnect power, adjust
your DIP switches, and the only light that should be lit is your RED power light.
HOW DO I CHANGE THE DIP SWITCH TO THE CORRECT SPEED OF MY FAN?
You will need to disconnect power, make your adjustment inside the hub, and then reconnect power.
CAN YOU CONNECT THE ATTIC FAN SMART CONTROL TO A SMART HOME
SYSTEM LIKE ALEXA, GOOGLE HOME, OR APPLE HOMEKIT?
No, in the current conguration the Smart Attic Fan Control cannot connect to a smart home
system. Smart home system control is not neccesary as the fan runs on it’s own and hardly ever
needs manual control.
WHAT HAPPENS IF I GET A NEW PHONE?
If you get a new phone, you will need to pair your new phone to the Hub. This is very easy to do
if you still have your old phone, or have another phone in the home that is currently paired to the
Hub. If you have another device that is paired to the Hub, follow the instructions on page 16 for
Pair Mode. If you do not have any other devices in the home that are paired to the Hub, you will
need to press the physical Pair button on the Hub.
This control features an innovative re safety shut-off that will automatically turn the fan off if it
detects a temperature above 182ºF in your attic. The purpose of this is to shut off in the event of a
house re to prevent the spread of ames.
