TRANSFORMER WIRING
TEST THE SYSTEM
Once the damper, pressure switch, and probe is installed. Turn on the range hood to high speed and confirm that the damper opens.
Turn off the hood and check to see if the damper closes.
A qualified HVAC contractor should also ensure the proper operation and venting of all combustion equipment in the home.
FALSE TRIPPING
Under certain extreme conditions there could be false tripping of the damper (opening when the range hood blower is off). If false tripping
is encountered, place an in-line backdraft damper (7" model no. 97, 8" model no. 438, 10" model no. 421) between the probe and the roof
or wall cap.
