Questions about this item

What power supply does the 100-240V motor need to operate?

The motor runs on 100-240V AC so you must wire it to a mains circuit with a matching voltage and a suitable disconnect.

Will the 25 in square rough opening match my existing 27 in square ductwork?

The damper fits a 25 in by 25 in rough opening; the 27 in overall frame overlaps the duct so the opening must be cut to 25 in square.

How do I confirm the actuator cycles correctly after installation?

Apply power and watch the single panel open fully; remove power and the spring should return it to the closed position.
