IMPORTANT OPERATING TIPS

The following important tips for operating this fan have also been provided.
• NEVER operate this fan without also opening a window or door. Doing so can excessively depressurize the
home.
• Only operate this fan when the outdoor air temperature is cooler than the indoor temperature.
• Make sure the home's air conditioner and furnace are OFF before turning on this fan. Running either of
these together with this whole house fan wastes money because the fan will force expensively conditioned
or heated air out of the home.
• We recommend running this fan through the night. The goal of using a whole house fan is to cool the entire
home, not just the air inside it. Once heated, the home's structure and contents continue to radiate heat
until reaching the temperature of the surrounding air. Running this fan through the night speeds up this cool
ing process and can then further "pre-cool" the home, reducing or eliminating the need to use air conditioning
the next day.
• If the home has a basement, extra cooling can be achieved by drawing in air through the basement
windows.
• This fan's cooling e ect can be increased or concentrated in particular areas by adjusting the location of
open windows. Visualize the path air will travel from the windows to your fan's opening. Generally, the
longer the path, the more cooling.
