wires (one from the compression bushing [240 Vac power source] and one from the ump) in the capacitor housing.
Using the electrical connector provided, connect the two orange leads to the other wire from the WPLLD transducer.
6. Twist the WPLLD/Adaptor assembly a couple of turns counterclockwise and then screw it into the capacitor housing
port.
7. Remove the plug from the Line Test port and install the port fitting in its place (see Figure 4-11).
8. Connect one end of the Sensing Line to the Line Test port fitting and the other end to the WPLLD transducer
(Figure 4-11). Tighten connections and attach one of the “WARNING” tags to the Sensing Line. With the two 6-32 x
0.375” screws provided, attach the conduit box cover bracket to the top of the transducer. Snap the removed capacitor
housing cover into the storage bracket.

4. Install the pump fitting from the kit in the Pressure Test Port. IMPORTANT! Seal the NPT pipe threads on the fitting
with a UL-classified nontoxic thread sealant suitable for the fuel involved. Do not apply sealant to the threads
adjacent to the flare fitting.
