Veeder-Root Line Leak Application Guide Special Installations Manifolded Line Applications DPLLD, PLLD and WPLLD leak detection systems can handle product lines supplied by multiple tanks and pumps,to a maxi- mum of 8 tanks and pumps per product line. Standard line leak sensing and check valve equipment should be installed at the primary pump. 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 410153-002),or SpikeCheck Valve Non-PSI Relief Valve for Standard Pump(P/N 410557-002), or FE Petro 65 psi Relief Check Valve(FE P/N 402459931)should be installed on each of the other pumps supporting the manifolded product line.The Non- Vented SwiftCheck Valve is rated to a maximum 70 gpm. For 5 HP Maxxum pumps in diesel,an additional in-line check valve with no pressure relief should be installed on the'Slave'pump to prevent backflow. 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 to control each secondary pump.The standard line leak modules will provide pump control output for the primary pump and the "Pump In"signal for the set. A typical manifolded line installation for DPLLD and PLLD is shown below: To Dispensers Flexible Pipe with 1 Flexible Pipe with Swivel or Union Swivel or Union DPLLD or PLLD Sensor Ball Valve Ball Valve Non-Vented SwiftCheck Valve SwiftCheck Valve(if req'd.)

Install the Red Jacket CPT Transducer Adapter Kit(Red Jacket part number 144-326-5)following the instructions with the kit.Thread the PLLD transducer in the mechanical LLD port of the pump. Seal any pipe threads using a UL-classified, nontoxic pipe sealant suitable for the fuel involved. The figure below illustrates two DPLLD and PLLD transducer installations in Red Jacket CPT pumps-consult"Check Valve Requirements"on page 6,to determine what check valve you will need to install to perform your intended level of testing. 2. Verify that the TLS-350 Series Console has Version x19 or later(TLS-450 Series Console has Version 1 or later)software. 3. Verify that the CPT Controller has Version 1.02 or later software installed. 12
