2. Insert the sensor cable into the mixed air chamber, stringing the cable to cover the air path, and secure as
needed.
NOTE: The flexible cable can be easily shaped to fit any duct size but observe a minimum bend radius of
two inches to prevent damage to wires or sensors.
3. Fasten the enclosure to the unit by drilling holes in the side of the unit and threading screws through the
mounting holes in the case.
4. For the cable leading to the AFMS controller, attach conduit to the 1/2" NPT threaded connection hole at
the bottom of the enclosure as needed.
5. Open the cover by pulling slightly on the latch on the right side of the enclosure while pulling on the cover.
