START-UP, OPERATION & TECHNICAL SUPPORT
Make sure that all wiring and connections have been made per this manual and acceptable wiring standards.
Make sure that no tools or construction debris have been left on, inside, or around the Whole House Fan. Plug the
power cord into a 120v grounded outlet. Verify main panel breaker supplying power to 120V outlet is energized.
Turn the unit ON using the arrow up button on the wall switch control. The damper doors will open and there will
be a 10 second delay before the fans turn on. Once the fans start running in low speed, press the up button again
to change to high speed to verify that the unit runs in both speeds. Allow for a slight delay when changing speeds
for the fans to adjust speed. Use the arrow up and down buttons to change between speeds while the unit is run-
ning. The VentCool 1.7 model has 2 speed settings.
Always turn the fan on using the UP button. Use the up and down arrows to change between the speeds. Turn
the unit on before pressing the timer button. Press the timer button 1 time for 1 hour, up to 12 times for 12 hour
operation. You can vary speeds while the timer is programmed, but turning the unit off will cancel the remaining
time on timer.
When the power is turned OFF, the fans will shut down and the damper door(s) begin to close. The door(s) will
shut tightly within 60 seconds.
