Veeder-Root Line Leak Applin Guide 0 <br />Special Installations <br />Manifolded Line Applications <br />PLLD and WPLLD leak detection systems can handle product lines supplied by multiple tanks and pumps, to a maximum of 8 <br />tanks and pumps per product line. <br />Standard line leak sensing and check valve equipment should be installed at the primary pump. <br />To perform 0.2 and 0.1 gph tests, a non -vented SwiftCheck valve (P/N 330020-416), or new Red Jacket 65 psi relief valve (P/N <br />410153-002),or SpikeCheck Valve Non -PSI Relief Valve for Standard Pump (P/N 410557-002), or FE Petro 65 psi Relief Check <br />Valve (FE P/N 402459931) should be installed on each of the other pumps supporting the manifolded product line. The Non - <br />Vented SwiftCheck Valve is rated to a maximum 70 gpm. <br />QNOTE: For 5 HP Maxxum pumps in diesel, an addtional in-line check valve with no pressure relief should be installed <br />' on the `Slave' pump to prevent backflow. <br />A relay on a Four -Relay module or 1/0 Combination module (TLS -350) or 1/0 Module (TLS -450) must be available to control <br />each secondary pump. The standard line leak modules will provide pump control output for the primary pump and the "Pump In" <br />signal for the set. <br />A typical manifolded line installation for PLLD is shown below: <br />To Dispensers <br />Flexible Pipe with <br />Flexible Pipe with <br />Swivel or Union Swivel or Union <br />Ball Valve Ball Valve Non -Vented <br />PLLD Sensor/ SwiftCheck <br />SwiftCheck Valve Valve (if req'd.) <br />Assembly <br />• O Q <br />• , 0 <br />❑ O <br />Warning Tag Master Pump Slave Pump <br />plldvnfdtanks.eps Lower Numbered Tank Higher Numbered Tank <br />Transducer Installation - Red Jacket CPT and Quantum CPT Pumps <br />This installation procedure is to be used with Red Jacket CPT and Quantum CPT Pumps. <br />1. Install the Red Jacket CPT Transducer Adapter Kit (Red Jacket part number 144-326-5) following the instructions with the <br />kit. Thread the PLLD transducer in the mechanical LLD port of the pump. <br />OIMPORTANT! Seal any pipe threads using a UL -classified, nontoxic pipe sealant suitable for the fuel involved. <br />The figure below illustrates two PLLD transducer installations in Red Jacket CPT pumps - consult "Check Valve Require- <br />ments" on page 5, to determine what check valve you will need to install to perform your intended level of testing. <br />2. Verify that the TLS -350 Console has Version x19 or later (TLS -450 has Version 1 or later) software. <br />10 <br />
