Connect a submerged area/velocity bare-lead sensor cable to a junction box
When a submerged area/velocity bare-lead sensor cable is used, connect the sensor cable to a
junction box.
1. Remove the four cover screws, cover and cover gasket from the junction box.
2. Remove the cable-clamp hex nut on the junction box.
3. Push the sensor cable into the junction box. Connect the sensor cable to the junction box. Refer
to the wiring diagram on the cover of the junction box.
4. Connect the tube in the sensor cable to the clear tube in the junction box. The clear tube is
connected to the exit fitting. Refer to
Figure 4 .
5. Push the sensor cable farther into the junction box sufficient to make a slight loop in the wires and
tubing, then tighten the cable-clamp hex nut.
6. Attach the cover and cover gasket to the junction box with the screws.
7. Connect the clear tube that is on the top tube fitting on the air dryer canister to the brass tube
fitting on the junction box.
8. Connect the short, quick-connect sensor cable to the Velocity port on the flow meter.
