0 <br /> PLLD Site Prep and Installation Guide Manifolded Product Line PLLD Installation <br /> PLLD System Installation Procedure <br /> rA Product spillage could create serious environmental and safety hazards. <br /> Fire,explosion,or ground contamination could occur. <br /> 1. If the SwiftCheck Valve is being installed at an existing site,drain the <br /> product pipeline using approved containers and procedures that will <br /> prevent product spillage. <br /> 2. Dispose of drained fuel properly.Use an approved container suitable for <br /> moving fuel.Dispose of fuel soaked materials properly and not into trash <br /> barrels that may be used by customers. <br /> 1. Turn off,tag,and lockout AC power to the submersible pumps and console before beginning the installation. <br /> 2. If the system is equipped with an in-line shutoff valve,close the valve to reduce the amount of drainage from the <br /> product lines.Collect drained fuel in an approved container. <br /> 3. Install the Non-Vented SwiftCheck valves in the slave pump's mechanical LLD pump port. <br /> 4. Install the PLLD transducer and SwiftCheck valve2 in the master pump [see Figure 4-11 on page 4-111. <br /> IMPORTANT! Sea] any NPT threads using a UL-classified,nontoxic pipe sealant suitable for the fuel involved. <br /> 5. Wire the system as shown in Figure 5-7,Figure 5-8,Figure 5-10,or Figure 5-11 as applicable.Follow the procedure <br /> described in"PLLD Controller Module Wiring"on page 5-3. <br /> MULTIPLE TANKS <br /> Follow these guidelines as you install a PLLD system into multiple manifolded tanks: <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 /> • A relay must be available on either a Four Relay Module or I/O Combination Module to control the pump on the <br /> higher-ntunbered tank.The PLLD Module will provide pump control output for the primary tank and the"Pump In" <br /> (Dispenser ON)signal for the set. <br /> • A Non-Vented SwiftCheck valve must be installed in the slave pump(s),. <br /> • Remove any other check valve or leak detect device in the line that is not shown. <br /> PLLD System Installation Procedure <br /> 1. Install the Non-Vented SwiftCheck valve3 in the mechanical LLD port of the slave pump(higher numbered tank). <br /> IMPORTANT! Sea]any NPT threads using a UL-classified,nontoxic pipe sealant suitable for the fuel involved. <br /> 2. Install the PLLD transducer and SwiftCheck valve4 in the master pump(lower numbered tank)as shown in Figure 4- <br /> 12 on page 4-11. If you are installing more than two tanks and pumps,connect the additional tanks and pumps the <br /> same way that you installed the higher numbered tank and slave pump. <br /> 1. For Maxxum Big-Flo,set the Pressurstat on the the slave STP to 20-25 psi. <br /> 2. Not required for FE Petro pumps(see Figure 4-8 on page 4-7),or Red Jacket Quantum or Maxxum Big-Flo pumps(see <br /> Figure 4-10 on page 4-9). <br /> 3. For Maxxum Big-Flo,and systems performing 3 gph only testing,set the Pressurstat on the the slave STP to 20-25 psi. <br /> 4. Not required for FE Petro pumps(see Figure 4-8 on page 4-7),or Red Jacket Quantum or Maxxum Big-Flo pumps(see <br /> Figure 4-10 on page 4-9). <br /> 4-10 <br />
