IMPORTANT OPERATING TIPS
The following important tips for operating this fan have also been provided.
• 
 NEVER
 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 cooling 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.
