9. Place the shield (from the installation kit) into the capacitor housing with open side up. Hold the shield at an angle
and place notched tab into the compartment first. Guide the two wires from the WPLLD transducer into the notch on
the shield [Figure 4-6 on page 4-6], leaving as much slack in the wires as possible above the shield (this will prevent
stressing them when the transducer is threaded into the pump).
10. Rotate the transducer about three turns counterclockwise, then screw it into the pump compartment and tighten it
securely.
11. Connect one end of the Sensing Line to the WPLLD transducer. Attach the other end of the Sensing Line to the
Pressure Test Port. 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 capacitor cover bracket to the top of the transducer. Snap the capacitor cover
into the storage bracket (Figure 4-14).

DUAL PUMPS IN SINGLE TANK
Follow these guidelines as you install a manifolded WPLLD system with dual pumps in a single tank:
•
Dielectric unions and flexible piping elements should be used as required by federal, state, and local requirements for
the specific piping application. Location of unions may vary with configuration.
•
An Interlock Relay must be installed so that the
secondary
pump is energized only when dispensing (but is turned Off
when
performing line tests). Refer to page
5-1 for specific installation instructions.
•
A non-vented SwiftCheck valve must be installed in the
secondary
pump.
1.
Turn Off, tag, and lockout AC power to the submersible pumps and console before beginning the installation.
2.
If the system is equipped with an in-line shutoff valve, close the valve to reduce the amount of drainage from the
product lines. Collect drained fuel in an approved container.
3.
Install the non-vented SwiftCheck in the
secondary
pump’s mechanical LLD pump port.
4.
Install the Non-Vented Check Valve in the pump discharge port of the
secondary
pump [Figure

IN FUEL SPRAYING DURING DISPENSER, PRODUCT
LINE, LEAK DETECTOR OR STP SERVICE.
PERFORM THE FOLLOWING BEFORE BEGINNING SERVICE:
1. CLOSE AFFECTED DISPENSER SHEAR VALVE AND TEST
FOR PROPER SHUTOFF OF THE VALVE IF PERFORMING
DISPENSER HYDRAULIC SERVICE.
2. REMOVE POWER TO THE SUBMERGED PUMP (STP) AND
TO LLD-300 AND LINE LEAK DETECTOR SYSTEM.
3. WEAR EYE PROTECTION.
4. COLLECT FUEL IN APPROVED CONTAINERS.
DO NOT CONTAMINATE ENVIRONMENT.
