Whole House Fans are designed to be installed within a home’s attic, which makes them and their sub-
components extremely difficult to access once installed. Test this fan outside of the attic Before in-stalling it.
Connect the fan to its controls and to a power supply, and ensure it operates properly by turning it on and cycling
through its speed settings. If any difficulties are encountered, contact

THEORY OF OPERATION
As a home heats up during the day, a large amount of heat is retained in its structure and contents. These
materials give off their heat slowly and continue to heat the home’s interior even if the outdoor temperature is
comfortable. Homeowners are then forced to endure either uncomfortable hot indoor temperatures, or the
expense of air conditioning.
Tamarack Technologies, Inc.
® and Ventura® whole house fans resolve this
dilemma by exhausting hot indoor air out of, and drawing cool outdoor air into, the home.
Each of our fans has been designed for quiet and efficient operation. As such, we strongly recommend running
this fan through the night to extract the maximum possible amount of heat from the home. This not only helps
maintain a comfortable indoor temperature, but essentially “pre-cools” the home ahead of the next day’s rise in
temperature, which reduces, or can even eliminate, the need for traditional air conditioning.
Fan Location Guidelines
• Locate this fan in a central location away from windows that will be opened to promote an even replacement
of air throughout the home and greater cooling effect.
• Locate this fan at the highest point possible to exploit natural convection and help exhaust the hottest indoor
air from the home.
• In a two-story home, the ideal location for this fan is typically in the open area at the top of the stairs.
• Avoid locating this fan in a narrow space or over hard flooring as the reflection of sound off of hard surfaces
can amplify its perceived noise.
• We specifically recommend against locating this fan in a bedroom as humans’ perception of noise is far
greater when the surrounding environment is quiet (such as within a bedroom at night).
• Within the attic, locating the fan near an electrical outlet or power supply can minimize the need for
additional electrical work.
