For all warranty andproduct questions, please contact Fill-Rite Technical Support at 1 (800) 720-*****************************************(M-F,8AM–5PMET).About This ManualFrom initial concept and design through its final production, your Fill-Rite pump is built to give you years of trouble-free use. To insure it provides that service, it is critical that you read this entire manual prior to attempting to install or operate your new pump. Become familiar with the terms and diagrams, and pay close attention to the highlighted*************************(M-F,8AM–5PMET).Safety InformationInstallationThe Fill-Rite FR300V series pump is designed to offer several different mounting configurations. It can be mounted on a skid tank using the tank adapter supplied with the pump (see attached diagrams) or mounted on a concrete island using an optional pedestal adapter (available through your Fill-Rite distributor). Regardless of mounting style, all tanks must be properly vented.The FR300V series pump has a built-in check valve with pressure relief to reduce unsafe excess pressure from thermal expansion of the fluid. It also features an integral bypass valve to help minimize wear when the pump is operating with the nozzle closed.Typical Skid Tank Installation Materials• 1-1/4" pipe cut to a length that will terminate at least 3" from the bottom of thetank when installed into the tank adapter with the tank adapter installed intothe tank flange (see SKID TANK INSTALLATION diagram).• Threaded pipe joint sealant appropriate for application.Installation Procedure1. Thread the 1-1/4" pipe into the tank adapter. Seal threads liquid tight withappropriate thread sealant.2. Screw the tank adapter into the tank flange; seal threads liquid tight withappropriate thread sealant.3. Mount the pump on the adapter; seal threads liquid tight with appropriatethread sealant.4. Fill-Rite recommends installation of an Anti-Siphon Device.Typical “Pedestal / Island” Installation Materials• 1-1/4" threaded suction pipe, cut to extend 32-1/2" above the island.• FRPA125 Pedestal Kit (includes Pedestal Pipe, Base, & Coupler).• Threaded pipe joint sealant appropriate for application.Installation Procedure 1. Remove the coupler from the pedestal pipe by loosening the set screws.2. Slip the pedestal pipe/pump base assembly over the 1-1/4" suction pipe.3. Loosen the screws in the pedestal base to allow the pedestal pipe to slide downexposing the end of the suction pipe.4. Screw the coupler onto the suction pipe; seal threads liquid tight withappropriate thread sealant.5. Slide the pedestal pipe into the coupler and tighten the set screws.6. Tighten the screws in the pedestal base.7. Mount the pump on the coupler seal threads liquid tight with appropriate thread sealant.Bung Adapter / Suction Pipe Assembly and InstallationFR300V series pumps feature a 2" Bung Adapter with integral connection for ananti-siphon device. When installing the suction pipe into the bung adapter, the suctionpipe must be inserted into the bung adapter correctly for proper operation. The suctionpipe threads into the tank adapter, and must be cut to a length that positions it at least 3"from the bottom of the tank.1. Measure and cut suction pipe to fit as described above.2. Examine the bung adapter to determine top and bottom for proper insertion ofthe suction pipe. The bung adapter is labeled to help: the end marked “PUMPSIDE” is the top of the bung adapter. Note that the internal threads for thesuction pipe are at the TOP of the opening.3. Wrap the threads of the suction pipe with the appropriate sealant for the fluidbeing pumped. Insert the suction pipe (with the threaded side up) into thebottom of the bung adapter until the threads engage.4. Tighten the suction tube into the bung adapter to create an air / fluid tight seal.5. Apply an anti-seize thread compound to the external threads on the bottom ofthe bung adapter. Install the assembled bung adapter and suction pipe into thebung opening on the tank. Tighten to a fluid / air tight seal.6. Install pump onto bung adapter using appropriate fluid sealant, and tighten to afluid / air tight seal.Anti-Siphon DeviceYour FR300V series pump comes from the factory ready to install an anti-siphon tube back to the tank. An anti-siphon device (a.k.a. vacuum breaker) is important because it will break a liquid siphon if there is an open nozzleor a leaking hose below the fluid level in the tank when the pump is turned off. Fill-Rite recommends anti-siphonkit # KIT700AS be installed from the pump outlet back to the vapor space in the tank.This illustration shows where to install the tube so that it terminates in the vapor space at the top of the tank.The tube must terminate in the vapor space; if it terminates below the fluid level in the tank, it will not preventsiphoning. It is very important there are no liquid traps in the tubing; it must have a continuous slope from thepump down to the tank, and can be connected into any opening in the top of the tank if the tank adapter is notused. Use reducer bushings as required for proper fit and seal.The 1/4" NPT opening in the side of the tank adapter terminates in the vapor space of the tank. Make liquid tightconnections using the appropriate sealant from the adapter to the anti-siphon outlet using a minimum of 1/4"metal tubing that is compatible with whatever liquid is being pumped. If the anti-siphon tank adapter is beingused and the 1/4" NPT opening is not used for the tubing, leave the factory installed plug in place.Fill-Rite offers Anti-Siphon kit # KIT700AS (available through your Fill-Rite distributor). This kit contains thenecessary fittings and tubing to complete the installation as pictured in this section. NOTE: This kit ONLY worksfor tank top installations.If not using the KIT700AS, you will need the KIT700AVB. This will allow you to connect a line either back to thetank, or to the bung adapter.TOP1 1/4" SUCTION PIPEANTI-SIPHON LINEWiring ProcedureUse the Voltage Selector Switch on the end of the pump to select the input voltage for the pump. NOTE: The pump comes from the factory pre-set to 115V AC position.Electric WiringOperating Instructions 1. Reset Meter to “0” (if applicable).2. Remove dispensing nozzle from nozzle boot.3. Move the switch lever to the “ON” position to power the pump.4. Insert the dispensing nozzle into the container to be filled.5. Operate the nozzle to dispense fluid; release nozzle when the desired amount of fluid has been dispensed.6. Move switch lever to the “OFF” position to stop the pump.7. Remove the dispensing nozzle from the container and store it in the nozzle boot.PadlockingYour Fill-Rite pump nozzle can bepadlocked for added security.With the pump turned off, and thenozzle in the stored position, a padlockcan be inserted through the nozzlerest and nozzle handle opening. Thisconfiguration prevents the nozzle frombeing removed from the nozzle cover.Diesel fuel, kerosene, mineral spirits, Stoddard solvents, heptane, bio-diesel (B20 max.), and bio-diesel (B21 – B100) using KIT300BD.Technical Information / SpecificationsDesign Features:• Inlet: Bung: 2" male NPT; Suction pipe: 1-1/4" female NPT or for “E” series models Bung: 2" male BSPT; Suction pipe: 1-1/2" BSPP.• Outlet: 1" NPT, or 1" BSPT (BSPT on “E” series models).• Cast iron pump housing: iron (composite) rotor, and carbon (composite) vanes.• Security: Pump equipped for padlocking (see page 7 for details).• Thermal overload protection.• Heavy duty switch.• 30 minute duty cycle.• Explosion proof motor UL listed with sealed bearings that require nomaintenance.• Integral check valve with pressure relief on inlet side prevents pressure build up and improves vertical lift.• Easy access strainer.• Automatic bypass valve.• 2" threaded base for tank openings.• Constant Amp Draw (Service Factor of 1.0):0 115V AC 60Hz – 9.8 amps / 50Hz – 11.4 amps.0 230V AC 60Hz – 4.9 amps / 50Hz – 5.7 amps.Overall Dimensions:• Model FR310V: 17.12" wide X 15" high x 14.9" deep.• Model FR311V: 17.12" wide X 19.25" high x 14.9" deep.• Model FR319V: 17.12" wide x 19.4" high x 14.9" deep.Shipping Weight:FR310V: 80 lbs. / FR311V: 91 lbs. / FR319V: 92 lbs.Accessories:See page 9 for a complete list of available accessories.Performance:• 26 psi (1.79 bar) maximum pressure at pump outlet.• Up to 35 gallons (132 liters) per minute.• Maximum viscosity of fluid pumped: #2 diesel fuel.• Maximum Pump Operating Temperature: 150 degrees F (66 degrees C).• Minimum Pump Operating Temperature: minus 13 degrees F (minus 25 degreesC) (note that for operation at lower temperatures, we recommend the “Arctic Nozzle” and “Arctic Hose” accessories section on page 9).Suction Lift:The lift in feet is equal to the vertical distance from the surface of the fluid in the tank to the inlet of the pump, LESS friction losses through the vertical and horizontal runsof pipe, all elbows, and other fittings.
