WPLLD System Installation
IMPORTANT! If there is a Stage II Vapor Recovery System installed in the site that includes a device in the pressurized
piping, see “WPLLD Installation with Stage II Vapor Recovery Systems” on page 4-14 for installation guidelines. For
both non-manifolded and manifolded installations, ball valves are recommended to minimize spillage during service and
to aid in verification of system leaks.
Red Jacket Pumps (Except Quantum and The Red Jacket)
SWIFTCHECK VALVE INSTALLATION
The SwiftCheck valve mounts directly into the Mechanical Line Leak Detector (LLD) pump port. It eliminates the need
to break product lines for installation and service. It also provides a means of precision testing on the packer discharge
O-ring and threaded discharge.
Since the SwiftCheck valve replaces the existing mechanical device, it is suitable in applications where there is no sump.
Follow these steps to install a SwiftCheck valve in the pump for non-manifolded installations:
1. Turn Off, tag, and lockout power to pump.
2. If the pump is equipped with a Mechanical Line Leak Detector (LLD), remove the mechanical unit and any related
tubing and fittings. Plug any tubing openings using appropriate fittings and seal using a UL-classified thread sealant
suitable for the fuel involved.
3. If the pump is not equipped with a mechanical LLD, remove the 2-inch mechanical LLD port plug.
4. Ensure that the sealing surface for the valve’s external O-ring is smooth and free from corrosion, pitting, and any
material build-up [Figure 4-1].
IMPORTANT! Failure to ensure a smooth sealing surface may result in false line leak alarms.
5. Catch all fuel drainage in an approved container and return to the tank. Do not contaminate the environment.
WARNING
TURN POWER OFF TO THE CONSOLE AND SUBMERSIBLE PUMP WHEN INSTALLING
THE WPLLD TRANSDUCER AND/OR SWIFTCHECK VALVE.
This equipment uses lethal voltages and attaches to accessory components which operate in
areas where flammable liquids and vapors may be present. When installing this product:
1. Use only supplied service parts to avoid compromising safety.
2. Do not allow WPLLD pump control wires to share conduit with wires from intrinsically
safe devices such as probes and sensors.
3. Wiring must comply with all applicable requirements of the National Electrical Code;
federal, state, and local codes; and any other safety codes.
