Switch Off,tag,and lockout all AC power to the TLS console,dispensers and submersible pumps. <br /> 2. If a ball valve is installed down line from the pump,close it. <br /> 3. Do one of the following: <br /> a. If the submersible turbine pump is equipped with a mechanical LLD,remove the mechanical unit and any <br /> related tubing and fittings,or <br /> b. If the submersible turbine pump is not equipped with a mechanical LLD,remove the 2-inch mechanical <br /> LLD port plug. <br /> 4. Thread the PLLD transducer into the LLD port(Figure 5). <br /> IMPORTANT!Seal any pipe threads using a.UL-classiified,nontoxic pipe sealant suitable for the fuel Involved. <br /> Pressurstat <br /> (adjustable PLLD transducer <br /> functional <br /> element) <br /> n <br /> Figure 7. PLLD/Pressurstat installation <br /> 5. Get a watertight cord grip from the transducer installation kit and coat its 1/2" NPT threaded end with UL- <br /> classified,nontoxic pipe sealant suitable for the fuel involved.Screw the cord grip into one of the openings in <br /> the weatherproof junction box. Feed the end of the PLLD transducer cable through the cord grip and then <br /> tighten the nut to ensure a watertight seal.Connect and seal the pressure transducer wires to the wires from <br /> the TLS console as described in`Epoxy Sealing PLLD Transducer Field Wiring Connections'on page 21. <br /> 6. Open the ball valve down line from the pump. <br /> 13 <br />
