OPERATING INSTRUCTIONS

Whole House Fans cool your home by pulling in fresh, cooler air from outside through open windows and

doors. For best results in a multi-story home, windows should be opened on alternate levels for most effi-

cient cooling. NEVER operate the fan without open doors or windows.

An added benefit of Whole House Fans is that they also provide forced attic ventilation, contributing to

cooler attic temperatures, assisting in reducing energy costs, as well as wear and tear on roofing compo-

nents.

Caution: If your home has a fireplace, be sure that the flue damper is closed to prevent chimney soot from

being drawn into the house by the fan. DO NOT operate the fan when a fire is burning in the fireplace.

WIRING INSTRUCTIONS

WARNING: Before proceeding with this step, disconnect the power supply at the service entrance,

or switch off the appropriate circuit breaker.

electrical and fire codes. Wire to 120 Volt, 60 Hz. circuit only, using 14-3 two-conductor

wiring with ground.

Install the included switches in a double gang, UL listed wiring box, in a wall close to the fan.
