1 9 <br />Veeder-Root Line Leak Applicion Guide <br />Special Installations <br />Manifolded Line Applications <br />DPLLD, PLLD and WPLLD leak detection systems can handle product lines supplied by multiple tanks and pumps, to a maxi- <br />mum of 8 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 />NOTE: 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 Series) or 1/0 Module (TLS -450 Series) must be available <br />to control each secondary pump. The standard line leak modules will provide pump control output for the primary pump and the <br />"Pump In" signal for the set. <br />A typical manifolded line installation for DPLLD and 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 />DPLLD or PLLD Sensor SwiftCheck <br />SwiftCheck Valve Valve (if req'd.) <br />Assembly <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 />QIMPORTANT! Seal any pipe threads using a UL -classified, nontoxic pipe sealant suitable for the fuel involved. <br />• The figure below illustrates two DPLLD and PLLD transducer installations in Red Jacket CPT pumps - consult "Check Valve <br />Requirements" on page 6, to determine what check valve you will need to install to perform your intended level of testing. <br />2. Verify that the TLS -350 Series Console has Version x19 or later (TLS -450 Series Console has Version 1 or later) software. <br />3. Verify that the CPT Controller has Version 1.02 or later software installed. <br />11 <br />
