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 ft. <br /> 3. If the pump does not have a Stage II vapor recovery device installed in the pressurized piping,remove the 2" <br /> NPT plug from line leak detector port. <br /> Install the PLLD transducer into the 2"NPT port as shown in Figure 12. <br /> IMPORTANT!Seal any pipe threads using a UL-classified,nontoxic pipe sealant suitable for the fuel In- <br /> volved. <br /> 4. If the pump does have a Stage 11 vapor recovery device installed in the pressurized piping,lubricate the <br /> external o-ring on the SwiftCheck valve using mineral oil or other suitable lubricant and thread the valve into <br /> the Red Jacket leak detector fitting(PfN 038-072)as shown in Figure 5 on page 11 instead of in the pump's <br /> leak detector port.Next thread the PLLD transducer into the SwiftCheck valve. <br /> IMPORTANT!Seal any pipe threads using a UL-classified,nontoxic pipe sealant suitable for the fuel in- <br /> J&1 volved. <br /> Because the PLLD transducer must be installed downstream from these devices,a monitored containment <br /> sump is required. <br /> There must not be a check valve installed between the SwiftCheck valve and the pump for PLLD to function <br /> properly. <br /> Ensure that the Healy pump is wired according to the manufacturer's instructions and utilizes isolation relays. <br /> 5. For PLLD operation there must be a FE Petro model R precision check valve in the pump,If necessary,replace <br /> the current check valve with a model R precision check valve (ref.Figure 12). <br /> Pressure Test Port-remove plug to access <br /> ,, <br /> valve clamp adjustment screw.Turn screw <br /> CCW until valve damp is all the way up and <br /> ® <br /> Manifold snug against manifold cover. <br /> �J <br /> cover <br /> valve clamp FE Petro O-ring <br /> (should be snug ' /� Part No.400211238 or 400333238 <br /> up against cover) I/"'*"\•I�' <br /> (``,�•,� I PLLD transducer <br /> � I <br /> Check valve <br /> spring <br /> Model R ( ! <br /> Precision \� <br /> check valve i j I 46 <br /> �o <br /> PU."VWIPAM <br /> I <br /> Figura 12 Locatlon of PLLD transducer and model R precision check valve in FE Petro pump <br /> 18 <br />
