3 . Push the diffuser frame in until it compresses against the
foam seal and the room side frame is flush against the
drywall. Be sure the diffuser frame is level and plumb and
secure it with the two (2) screws provided.
Note: When installed correctly the diffuser frame should seal
to the cabinet discharge air opening and no discharge
air will be lost between the unit and the wall cavity.
