Installation Instructions

QUIETCOOLSYSTEMS.COM

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 airflow and performance.

2.2 Installing AFG (Attic Fan Gable) 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 wood 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.

2.3 NOTE ABOUT THE AFG SMT-3.0

The AFG SMT-3.0 features a 10-speed ECM motor that automatically

changes speed based on temperature and humidity conditions

within the attic.

Sometimes this automatic speed change can cause a slight, tinny vibration sound on certain gable vents

when the fan is switching down to the lower speed ranges.

To prevent this, please follow the steps below.

1. Purchase general silicon caulking from any hardware

store.

2. Caulk over the steel mesh that touches the horizontal

slats of the gable vent.

3. Proceed to the installation in section 2.1.
