PLLD Transducer Installation Red Jacket Standard and Quantum Pumps(PLLD w/SwiftCheck) <br /> Red Jacket Standard and Quantum Pumps (PLLD w/SwiftCheck) <br /> Use this installation procedure to install a PLLD transducer with a SwiftCheck valve in a Red Jacket Standard or <br /> Quantum pump. <br /> 1. Switch Off,tag,and lockout all AC power to the TLS console,dispensers and submersible pumps. <br /> 2. If a ball valve is installed down line from the pump,close it. <br /> 3. Do one of the following: <br /> a. If the submersible turbine pump is equipped with a mechanical LLD, remove the mechanical unit and any <br /> related tubing and fittings,or <br /> b. If the submersible turbine pump is not equipped with a mechanical LLD, remove the 2-inch mechanical <br /> LLD port plug. <br /> 4. Ensure that the sealing surface for the SwiftCheck valve's external o-ring is smooth and free from corrosion, <br /> pitting,and any material build-up [Figure 3]. <br /> QIMPORTANT!Failure to ensure a smooth seal surface can result in false line leak alarms. <br /> Pressurstat Functional element <br /> (adjustable (non-adjustable type) <br /> functional O <br /> element) <br /> 0 <br /> OR <br /> ® Sealing surface <br /> of pump port <br /> z <br /> E <br /> Figure 3.

Lubricate the external o-ring on the SwiftCheck valve using mineral oil or other suitable lubricant. <br /> 6. If there is no Stage II vapor recovery, install the SwiftCheck valve [Figure 41 in the mechanical LLD pump port. <br /> Thread the PLLD transducer into the SwiftCheck Valve. <br /> IMPORTANT!Do not overtighten the SwiftCheck valve when installing it into the pump.Overtightening the <br /> valve can cause a flow restriction in the line! <br /> Seal the NPT threads only with a UL-classified,nontoxic pipe sealant suitable for the fuel involved. <br /> 10 <br />
