• Locate this fan in a central location, away from windows that will be opened during
its operation. Installing this fan centrally promotes an even replacement of air through-
out the home, and the longer the path of air travels from an open window to the fan,
the greater the cooling e ect.
• The damper provided with this fan can only be installed in a horizontal orientation,
thereby requiring the unit to be installed in the ceiling.
• Locate this fan at the highest point possible. This exploits natural convection and helps
the fan exhaust the hottest indoor air from the home.
• Typically, the ideal location for this fan in a two-story home is in the open area at the top
of the stairs.
• Avoid locating this fan in a narrow space or over hard  ooring as sound re ecting o of
hard surfaces can amplify its perceived noise.
• Even though the Cascade series fan systems are engineered to be extremely quiet, we
speci cally recommend against installing it in a bedroom as humans’ perception of noise
is far greater when the surrounding environment is quiet (such as within a bedroom at
night).
By running this fan through the night, homeowners can extract the maximum possible amount of heat from their
home’s structure and contents. This essentially “pre-cools” the home ahead of the rise in temperature the next day,
which can reduce or even eliminate the need for air conditioning. This Cascade Whole House Fan has been designed
speci cally for quiet and e cient operation. As such, we strongly recommend homeowners run this fan through the
night to reduce their energy expense.
With these principles of operation in mind, adhere to the following guidelines when choosing a location for
this fan:
WHERE TO LOCATE THIS FAN
The best location for this fan is determined by an under-
standing of its 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 up their heat
slowly and, in doing so, continue to heat the home’s inte-
rior even though the outdoor temperature may, in fact, be
very comfortable in the evening and at night. Thus, home-
owners are forced to either endure the hot conditions in-
side of their homes or turn on their air conditioners and
bear the expense thereof.
When operated properly, this whole house fan can resolve
this dilemma by forcing the hot air inside a home out and
drawing cool air from outside in. The illustration to the right
depicts how this fan exhausts hot air into the attic and draws
cool air into the house from outdoors through open windows
and/or doors.
