PLLD Site Prep and Installation Guide PLLD Installation in Red Jacket Quantum Pumps with SpikeCheck Valve <br /> PLLD Installation in Red Jacket Quantum Pumps with SpikeCheck Valve <br /> The PLLD transducer mounts directly into the mechanical line leak detector pump port.It eliminates the need to break <br /> product lines for installation and service. <br /> Since the PLLD transducer replaces the existing mechanical device,it is suitable in applications where there is no sump. <br /> 1. Do one of the following: <br /> a. If the submersible turbine pump is equipped with a mechanical LLD,remove the mechanical unit and any related <br /> tubing and fittings,or <br /> b. If the submersible turbine pump is not equipped with a mechanical LLD,remove the 2-inch mechanical LLD port <br /> plug. <br /> 2. Thread the PLLD transducer directly into the mechanical LLD port on the pump(see Figure 4-10). <br /> IMPORTANT! Seal any pipe threads using a UL-classified,nontoxic pipe sealant suitable for the fuel involved. <br /> 3. Feed the PLLD transducer cable through the watertight cord grip on the PLLD transducer junction box.Tighten the <br /> nut on the cord grip to ensure a watertight seal. <br /> �70ftvq antunper.ePs i <br /> I <br /> . ✓ `� _, PLLD <br /> 'I = transducer <br /> f t!

PLLD Installation in Red Jacket Quantum Pumps(w/SpikeCheck Valve Assy) <br /> Manifolded Product Line PLLD Installation <br /> Version 9/109 or later software provides a feature that permits the use of PLLD on product lines supplied by: (1)two <br /> submersible pumps in a single tank or(2)two tanks with two submersible pumps,up to a combined maximum of eight <br /> tanks and pumps.Please refer to the System Setup Manual (Manual No.576013-623)for detailed instructions on <br /> selecting this option.For additional parts you need when installing a manifolded PLLD system,see"Before You Begin' <br /> on page 1-2. <br /> DUAL PUMPS IN SINGLE TANK <br /> Follow these guidelines as you install a manifolded PLLD system with dual pumps in a single tank: <br /> • Dielectric unions and flexible piping elements should be used as required by federal,state,and local requirements for <br /> the specific piping application.Location of unions may vary with configuration. <br /> • An interlock relay must be installed so that the slave pump is energized only when dispensing(but is switched Off <br /> when performing line tests). <br /> • A Non-Vented SwiftCheck valve must be installed in the slave pump. <br /> 4-9 <br />
