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.

+ High Efciency Multi-Speed Motors
+App Based Smart Control
+Integrated Mounting Tabs with Anti-Vibration Pads
+Designed and Built in California

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 signicant 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 efciently and effectively. If an attic has less than 1:750 attic
venting, the system may not operate as efciently, 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.
Insufcient venting is a very simple problem to x. Roong contractors can add extra venting to most
homes simply and easily. The most common types of venting is shown in the chart below.

2. INSTALLATION
2.1 INSTALLING ATTIC GABLE FAN
NOTE: The AFG model fans are designed to mount behind existing vents. If no vent exists, one must
be installed. Vent should be installed in the upper center section of the gable.
1. Installing the QuietCool AFG is very easy. To install the AFG, simply mount the gable fan to your gable
vents as shown in the following steps:
Flush Mount: The AFG can be mounted ush to a rectangular type
louver by fastening through the mounting brackets to the frame of the
louver (as shown in Figure 2.1A).
As stated in the note above, any area of the louver that is not covered
by the AFG must be sealed off in order to prevent air leakage, which
may hinder performance.
This is the most conventional method of mounting the AFG. We
recommend using the Flush Mount option if possible for all applications.
Wide Mount: The AFG can be mounted on a wide louver, but additional
mounting steps must be taken in order for the fan to work properly. As
shown in Figure 2.1B, two additional boards must be fastened to the
boards framing the gable vent so the AFG can be mounted securely.
As stated in the note above, any area of the louver that is not covered by
the AFG must be sealed off in order to prevent air leakage, which may
hinder performance.
Odd Mount: The AFG can also be mounted off center for an odd shaped
louver (as shown in Figure 2.1C).
As stated in the note above, any area of the louver that is not covered by
the AFG must be sealed off in order to prevent air leakage, which may
hinder performance.
While this is not the most ideal way to mount the gable fan, it is possible.
However, since the fan is not completely covering the vent, maximum
airow will not be achieved.
NOTE: The AFG can be mounted on many other types of louvers, including triangle vents,
round vents, half-round vents, etc. If the vent is smaller than the area of the fan, we recommend
constructing a chamber that surrounds the vent, and then mount the AFG to the chamber to ensure
maximum airow and performance.

2.2 INSTALLING AFG VENT COVERS
Included with your QuietCool Attic Gable Fan are four vent covers
that are designed to be installed around the attic fan housing to
block any air backdrafting into the attic through a gable vent that
is larger than the attic fan cylinder, causing air to cycle in and out
around the vent.
1. Take the vent cover and match it to one of the sides around
the attic fan housing.
2. Using the two provided screws, attach each corner to the
wood framing around your gable vent. (See picture for screw
locations)
3. Repeat step 1 and 2 for the three additional covers.

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 conguration 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.
