The pumps come with unique features that set them apart from non-intelligent pumps. For specific warranty details, please refer to fillrite.com.

Product Usage Instructions

Before using the NX25-120 & NX25-240 Series AC Fuel Transfer Pumps, it is important to read and adhere to the safety warnings and precautions provided in the manual. Failure to do so may result in serious bodily injury or death.

Static Electricity Prevention

To minimize the risk of static electricity build-up and potential explosions, follow these precautions:

• Use only static wire conductive hose when pumping flammable fluids.
• Keep the fill nozzle in contact with the container being filled during the filling process.
• Avoid spark or static discharge.

Proper Sealing of Pipe Joints and Connections

To prevent leaks and reduce the risk of fire and explosion, seal threaded pipe joints and connections with appropriate sealant or sealant tape.

Thermal Overload Protection

The pump motor is equipped with electronic protection from thermal overload. If the motor overheats, it will slow down. To reset this safety feature and continue using the pump, allow the motor to cool down and then cycle power or the switch. The pump will not restart until properly cooled.

Fluid Compatibility

The NX25-120 & NX25-240 Series AC Fuel Transfer Pumps are not suitable for use with fluids intended for human consumption or fluids containing water. The materials of construction are not food grade. If water enters the pump, flush it immediately with a petroleum product (gasoline, diesel, kerosene, etc.) to remove residual water and prevent rust and corrosion.

Use of FillRite Filter

It is recommended to use a FillRite filter on the pump outlet to ensure that no foreign material is transferred to the fuel tank. Foreign material can damage the equipment being fueled.

Fueling Safety

When fueling, it is crucial to remove all possible sources of ignition to a safe distance or extinguish them. Sources of ignition include open flames, cigarettes, static discharge, and electrical connections that can create a spark. Igniting explosive vapors can result in explosions, fires, and severe injuries or death.

Unique Features of the Nextec Pump

Your next fuel transfer pump will perform differently from non‑intelligent pumps on start‑up and while operating. You will want to keep the following in mind as you begin to use and learn how your nextec Intelligence pump operates.

• On initial start-up, the pump may rev momentarily, but will slow down, as if idling, as it responds to the load it senses. This is a normal condition, and it will continue at this low
  speed until you squeeze the handle on the dispensing nozzle to begin fluid flow.

• When you squeeze the nozzle handle to begin flow, the microprocessor in the pump will sense the change and will raise the RPMs to meet the load.
  It is not uncommon for the pump to change RPMs during operation. It will do this as it senses performance parameters are changing; for example, if you increase or decrease the
  flow at the nozzle, the electronics controlling the motor will sense the changes and adjust the motor speed to optimize performance.

• If the pump senses a condition that is outside normal operating parameters (e.g. low input voltage), it will sound a series of tones to alert you to the condition, and to help you
  diagnose it. See the “Intelligent Tones” section of the Troubleshooting Guide on page 14 for greater detail on this feature.

• Your nextec pump has a Continuous Duty Cycle, meaning it does not have to be shut off to “rest” after a specific period of use. This allows you to move from fueling one piece of
  equipment to another without having to shut the pump off. The Nextec Intelligence does, however, have an automatic shut-off if the pump is left running in bypass mode (without
  dispensing any fluid) for 20 minutes. This feature protects from unnecessary power consumption and excessive wear to the pump in the event you forget to shut the pump off.
  Should the pump turn itself off under these conditions, simply cycle the power switch off, and then back on to restore pump operation.

• The next Intelligence will also shut the motor down if:

• Pump temperature exceeds threshold parameters

• Input voltage is outside threshold parameters

• The rotor is locked

NOTICE

A Fill‑Rite filter should be used on the pump outlet to ensure no foreign material is transferred to the fuel tank. Foreign material can damage the equipment being fueled.

Fueling Safety

DANGER

Fumes accumulated while fueling create an Explosive Atmosphere. It is CRITICAL that all possible sources of ignition be removed to a safe distance or extinguished. Sources of ignition would include (but not limited to) open flames, cigarettes, static discharge, or electrical connections that can create a spark. Explosion, fire, and severe injury or death will occur if the explosive vapors are ignited.

As a tank is being filled, air is displaced and exits via the fuel tank vent creating fumes, which when accumulated create an Explosive Atmosphere. To avoid possible explosion of accumulated vapors, it is critical to keep possible sources of spark/ignition at safe distances from the fuel vapors. The accompanying diagram shows the minimum safe distances between the storage tank, dispenser, and power source

WARNING

• static electric spark can occur when filling portable containers sitting on truck bed liners, or on any vehicle’s carpeting or floor matting. This spark will explosively ignite a gasoline vapor fire and cause SERIOUS INJURY or DEATH.
• STATIC ELECTRIC SPARK EXPLOSION HAZARD.
• NEVER fill portable containers that are in or on vehicles.
• ALWAYS PLACE CONTAINERS ON THE GROUND.
• Keep the nozzle in contact with the container while filling.

Installation

NX25‑120 and NX25‑240 pumps are 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 (model FRPA125 is available through your Fill‑Rite distributor). Regardless of mounting style, all tanks must be properly vented.

CAUTION Do not use check valves or foot valves unless they have a proper pressure relief valve built into them. Note that check valves will reduce rate of flow. Nozzle Boot Installation

Install the nozzle boot using the supplied attaching bolt. Note that the bolt is inserted through the hole closest to the nozzle opening, and the boot is then positioned so the peg on the pump mounting surface inserts in the top second hole of the boot. This allows for correct alignment of the nozzle when inserted into the boot. Foot Mount Installation
The mounting foot is bolted to the bottom of the pump using the four supplied socket head cap screws. Mount the foot with the bolt flanges inboard of the mounts on the pump as illustrated. Torque to 50 in‑lbs with 4mm hex key.

Anti-Siphon Device

NX25‑120 and NX25‑240 pumps 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 nozzle or a leaking hose below the fluid level in the tank when the pump is turned off. Fill‑Rite recommends that anti‑siphon kit #KIT321ASN 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 prevent siphoning. It is very important there are no liquid traps in the tubing; it must have a continuous slope from the pump down to the tank, and can be connected into any opening in the top of the tank if the tank adapter is not used. Use reducer bushings as required for proper fit and seal. The ¼” NPT opening in the side of the tank adapter terminates in the vapor space of the tank. Make liquid‑tight connections using the appropriate sealant from the adapter to the anti‑siphon outlet using a minimum of ¼” metal tubing that is compatible with whatever liquid is being pumped. If the anti‑siphon tank adapter is being used and the ¼” NPT opening is not used for the tubing, leave the factory-installed plug in place. Fill‑Rite offers Anti‑Siphon kit

KIT321ASN (available through your Fill‑Rite distributor). This kit contains

the necessary fittings and tubing to complete the installation as pictured in this section.
NOTE: This kit ONLY works for tank top installations.

Tank Installation

NX25‑120 and NX25‑240 pumps are mounted to the bung of a tank by way of the tank adapter that is bolted to the inlet flange. The suction tube threads into the bottom of the tank adapter, and must be cut to a length that positions it at least 3″ from the bottom of the tank. The tank must be equipped with a vent cap.

Materials

• 1‑1/4″ steel pipe cut to a length at least 3″ above of the bottom of the tank when screwed into the tank adapter, with the tank adapter screwed into the bung connection on top of the tank.
• Thread pipe joint sealant appropriate for the application.

Installation Procedure

1. Thread the 1‑1/4″ pipe into the tank adapter. Seal threads liquid‑tight with the appropriate sealant (Figure 1).
2. Screw the tank adapter (with suction pipe) into the tank bung; seal threads liquid‑tight with appropriate thread sealant (Figure 2).
3. Mount the pump on the adapter; making sure the seal and screen are installed as shown (Figure 3).
   NOTE: Tank adapters come in either NPT or BSP threads, depending on the model you purchase (see page 11 for model-specific information).

NOTICE

Be certain the screen is properly seated in the indentation in the tank adapter before installing the seal and tank adapter to the pump. Failure to properly seat the screen can result in fluid leakage

Electrical Wiring

WARNING

Electrical wiring should be performed ONLY by a licensed electrician in compliance with local, state, and national electrical codes NEC/ANSI/ NFPA 70, NFPA30, and NFPA 30A, as appropriate to the intended use of the pump. Threaded rigid conduit, sealed fittings, and conductor seal should be used. The pump must be properly grounded. Improper installation or use of this pump can result in serious bodily injury or death!

CAUTION

All pumps should be operated at the Rated Nameplate Voltage. Power should be supplied to the pump from a dedicated 20 amp circuit breaker. No other equipment should be powered by this circuit. Wiring must be of sufficient size to carry the correct current for the pump. Voltage drop will vary with distance to pump and size of wire; refer to the National Electrical Code (NEC), or local codes, for Voltage Drop Compensation to be sure you are using the correct size wire for your application.

Wiring Procedure

NOTICE

Be certain the gasket for the cover is in place, and the screws draw the cover down tight over the junction box. There must be no gap between the junction box and it’s cover.

1. Remove the junction box cover and straighten the wires to make sure the stripped wire ends are accessible outside the junction box.
2. Connect the pump wires to the power supply lines according to the diagram. Be certain to properly insulate the connections with the appropriate wire nuts or other connectors. Note that the ground wire MUST be connected. The conduit connection is ½” NPT threading. (For all NX25‑240B models, single location, entry threads are M20 x 1.5).
3. Fold the wires back into the junction box and replace the cover, making sure the cover gasket is in place. Torque fasteners to 44 in‑lbs with 4mm hex key.

WARNING

NX25‑120 & NX25‑240 pumps are NOT dual voltage. Wire according to the voltage on motor tag.

Operational Safety

DANGER

DO NOT use pumps in enclosed areas when pumping hazardous or explosive fluids. The pumping area should be well-ventilated. Concentrated vapors in an enclosed area are noxious and highly explosive!

WARNING

NEVER disconnect the power wiring from the pump while the pump is switched on or connected to a power source. ALWAYS switch the pump off and disconnect the power source PRIOR to disconnecting the power wiring from the pump. Electrical shorts, sparks, or unexpected start-ups can occur.

WARNING

Use caution when operating the pump. The hoses can be a trip hazard; caution should be exercised while moving around the hoses to avoid tripping or entanglement.

WARNING

The pump assembly can become hot with extended use. Use caution if you have to touch the pump after e WARNING extended periods of use.

Operating Instructions

NOTICE

The motor has power at all times when connected to a power source. The switch does not apply or interrupt power to the motor. High voltage may still be present inside the pump after power is removed.

CAUTION

Always keep the nozzle in contact with the container being filled during the filling process to minimize the possibility of static e CAUTION electricity build up.

1. Remove the dispensing nozzle from the nozzle boot.
2. Move the switch lever to the “ON” (raised) position to start the motor. The pump should start and settle into a slow idle.
3. Insert the dispensing nozzle into the container to be filled.
4. Operate the nozzle to dispense fluid; release the nozzle when the desired amount of fluidhas been dispensed.
5. Move the switch lever to the “OFF” (lowered) position to stop the motor.
6. Remove the dispensing nozzle from the container being filled and store it in the nozzle boot.

Pad Locking

Your Fill‑Rite nozzle can be padlocked to the pump for added security. With the pump turned off, and the nozzle in the stored position, a padlock can be inserted through the locking link and the nozzle handle opening. This configuration prevents the nozzle from being removed from the nozzle boot. The locking link is located on the nozzle side of the pump and can be pivoted into position to work with the nozzle listed on the barrel label of your NX25‑120 or NX25‑240 pump. Use the appropriate position and hole to lock your nozzle securely to your NX25‑120 or NX25‑240 series pump.

Servicing the Bypass Valve (Disassembly)

WARNING

Disconnect electrical power and relieve any pressure in the lines prior to servicing this pump! Failure to do so can result in damage to the equipment and personal injury or death!

NOTICE

Removal of the bypass valve in the NX25‑120 or NX25‑240 series pump requires special attention; please adhere to the replacement procedure in the kit instructions to minimize the possibility of damaging the pump housing during the removal and re‑installation process. Kit instructions are available at fillrite.com.

The bypass valve is located inside the pump housing.
It is accessed through the inlet and outlet openings.

It consists of three main components (Figure 1):

• A. Bypass Valve Retainer
• B. Bypass Valve Spring
• C. Bypass Valve

1. Unbolt the pump from the tank adapter.
2. Using a blunt object approximately 4″ long (i.e. a deep well socket on an extension) inserted in the inlet opening, push the bypass valve firmly in place against the seat it seals on (Figure 2).
3. While holding the bypass valve firmly in place with the socket, insert needle nose pliers (at least 4″ long) into the outlet opening and grasp the bypass valve retainer (Figures 2 & 3).
4. Push the bypass valve retainer down slightly and rotate it 90 degrees counter‑clockwise. This will align the slot in the retainer with the key on the valve, allowing you to remove the retainer (Figures 2 & 3).

Servicing the Bypass Valve (Reassembly)

WARNING

Always wear eye protection anytime you look into the Pump Outlet; a mispositioned or improperly installed valve spring retainer can pop up unexpectedly. Note that the use of a small flashlight can help you better see and more easily align the components in this task.

1. Using needle nose pliers, place the bypass valve retainer on top of the bypass valve spring. Carefully align the slot at the top of the bypass valve retainer with the locking tab on top of the bypass valve (Figure 4).
2. Push the bypass valve retainer down over the locking tab on the bypass valve. Push the retainer down (compressing the spring) until it is completely below the locking tab (Figure 5).
3. Rotate the bypass valve retainer 90 degrees counterclockwise and allow the spring to gently push it back up to contact the locking tab. The locking tab MUST be seated in the indentation in the bypass valve retainer (Figure 6).

WARNING

It is critical that the locking tab be seated in the indentation in the bypass valve retainer as illustrated. Failure to do so can cause the retainer to come off when operating in bypass mode, potentially damaging the pump, or ejecting upward through the pump outlet while servicing.

Intelligent Tones
Your next pump features a self‑diagnostic system that will aid you in troubleshooting should the need arise. The pump will emit a series of tones; note the order and number of high and low-pitched tones to determine the fault condition.
Depending on the condition the pump senses, it will generate either a 3-tone code or a 4-tone code:

• 3-Tone codes indicate an application fault; something dealing with the installation of the pump, like a priming or supply voltage concern.
• 4-Tone codes indicate a pump fault; a condition outside the operating parameters of the pump, like an over‑temperature condition, or something dealing with the pump’s internal electronics.
  Refer to the table below to determine which condition your pump is detecting, and how to resolve it. In the chart below, arrows pointing up (↑) indicate high tones, and arrows pointing down (↓) indicate low tones. Conditions listed in BOLD are not field serviceable, and require the pump to be returned to the manufacturer.
