that senses the exhaust duct static pressure caused by the operation of the

range hood. A direct low-voltage wiring connection between the pressure kit

sensor and the Damper is required.

 Any Range Hood and Most Bathroom or Utility Room Exhaust Fans

‐ The universal design of the pressure switch kit makes it compatible with virtually

any range hood and any bathroom or utility room exhaust system that has an

exhaust duct static pressure of at least 0.05 in w.g. A direct low-voltage wiring

connection between the pressure kit sensor and the Damper is required.
