Two ways to connect ductwork to a factory-shipped unit.

IMPORTANT:

Remove shipping tape from damper

Remove the shipping tape from the damper flap and make sure that damper flap opens and closes freely inside the ductwork. Use duct tape to make ductwork connections secure and air-tight.

Remove shipping ring from blower inlet

Remove the shipping ring from the blower inlet before operating the ventilator.
