Three key factors that must be
considered when choosing and installing the proper Attic
Breeze solar powered ventilation product for your
application are product orientation, sizing for the
application, and ensuring that the correct amount of intake
ventilation is present. When these factors are properly
balanced, your Attic Breeze solar powered ventilation
product will deliver maximum airflow performance for your
application. Below are some helpful tips to make your
product installation a breeze.
Become Familiar with Your New
Attic Breeze Fan
Attic Breeze solar attic fans ship
completely assembled and ready for installation. Each one
of our solar attic fans are tested before leaving the
factory, conforming to our strict quality assurance
standards. When your new solar attic fan arrives, make sure
to remove the product from the packaging and inspect for any
damage that may have occurred during shipping. Your Attic
Breeze solar attic fan may begin to operate when removed
from its packaging, even with indirect sunlight, so be sure
to keep the solar panel covered until you are ready to use
the product.
Turn the solar attic fan upside down so
that you are directly facing the fan blade. Roof mounted
Attic Breeze solar powered ventilation products are equipped
with a power cable that is securely taped to the inside of
the fan housing for shipping. Make sure to remove the
packaging tape and allow the power cable to hang freely
before installing. If your product is equipped with a
traditional thermal switch or Breeze Mate™ control system,
plug in your attachments to the power cable before
proceeding with installation of the fan.
Test your Attic Breeze solar powered
ventilation product before installation to become familiar
with its operation. The solar panel should be tested in
direct sunlight for maximum performance. The more direct
sunlight the solar panel receives, the faster the Attic
Breeze fan will operate. Please note that our solar powered
ventilation products are designed to be extremely quiet,
even when operating at high speeds. Excessive noise during
testing or unexpected vibration of the product may indicate
that damaged occurred during shipping. If you believe that
your product may be damaged, contact an Attic Breeze
customer support specialist for assistance before
proceeding.
SAFETY NOTICE: Use caution
when testing your Attic Breeze solar powered ventilation
product. Keep hands, hair, and
loose clothing clear of the fan blade during
operation! Do not allow packaging material to interfere with the fan
blade during testing as damage may occur.
When equipped with a traditional thermal
switch, your Attic Breeze solar powered ventilation product
will only operate at temperatures above roughly 75°F. If
the outside ambient temperature is below this range, the fan
may be tested by warming the thermal switch to above its
operational range (for example by holding the switch in your
hand). Contact your Attic Breeze representative for more
information.
Choosing the Best Location for
Installation
Determining the best location for
installation of your new Attic Breeze solar powered
ventilation product is a two-step process. For roof mounted
models, the solar attic fan should be positioned roughly
toward the middle of the home's roof line and approximately
3 feet below ridge. The idea is to balance the air flow
through your attic to achieve a maximum amount of cross-flow
ventilation from all air intake sources. When installing
Attic Breeze products in conjunction with ridge vents, the
solar attic fan unit should be installed a minimum of 5-7
feet below the ridge vent to allow for balanced air flow
through the attic. Experience shows that this distance will
typically allow enough space for proper balancing of air
intake ventilation from both the ridge vent and other
passive roof vents. Wall and Gable mounted fans may be
installed in any location that allows unrestricted airflow
to the fan unit.
Your Attic Breeze solar powered
ventilation products should not be installed any closer than
10 feet within an existing passive vent. Studies show that
installation of powered ventilation products too close to
existing passive vents may result in short circuiting of
airflow and produce poor attic cooling performance. For
best results, block off any passive vents that are too close
to your chosen installation location or find an alternative
location that will allow for the best balancing of airflow
through the attic.
For all areas of North America,
the solar panel on your product should be oriented toward
the south to achieve optimum sun exposure throughout the
day. The appropriate Attic Breeze model and solar panel
bracket system will depend on the location you have chosen
for installation of your product. Roof mounted models
featuring a unit mounted solar panel are best for south,
east, or west orientations. For roofs installations that
face north or in locations that may be partially shaded, an
Attic Breeze model featuring a remote mounted solar panel is
recommended.
Shadows which may cross your product's
solar panel during the day will have a decidedly negative
effect on its performance. Avoid installing your Attic
Breeze solar attic fan in areas that may receive shade
during the day or consider using an Attic Breeze model
featuring a remote mounted solar panel for your application.
Sizing for the Application
The process of determining how much
ventilation your application needs is dependent on many
factors. We encourage you to use the "What's
Right for Me?" section of our website to
find the best Attic Breeze product for your application. In
general, if the correct amount of ventilation is not
installed appropriate to your application, you will not
observe the expected cooling performance. Contact an Attic
Breeze customer support specialist if you need assistance in
determining the correct amount of ventilation for your
application.
Proper Air Intake Ventilation
Proper air intake ventilation is the one
of the most important aspects of ensuring a successful
installation. Attic Breeze solar powered ventilation
products must be supplied with enough make up air to
minimize air flow resistance through the attic for our
products to operate at their optimum performance levels. If
air intake ventilation is insufficient, our solar attic fans
are designed to slow down and generate less air flow,
resulting in decreased cooling performance. This a safety
featured designed to minimize the possibility of attic
depressurization.
To ensure that sufficient air intake
ventilation is present, please read the "Air
Intake Ventilation" section of our
website and confirm that your attic is equipped with the
proper amount of required ventilation. If your product
is equipped with the Breeze Mate™ control system, simply run
the attic depressurization test on your controller to verify
that your Attic Breeze product is installed properly and
operating with the required amount of ventilation.
