4. Connect the DG-700 to the Blower Door fan speed controller using the fan control cable. Plug one end of the cable
into the 3.5 mm fan control output jack on the top of the DG-700, and plug the other end of the cable into the
communication jack on the side of the fan speed controller box.
5. Connect tubing between the DG-700 and the Blower Door system (tubing connections are detailed in the Blower
Door operation manual).
