Unique Features of the nextec Pump
Your nextec 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 RPM’s to meet the load.
It is not uncommon for the pump to change RPM’s 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 features 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, then back on to restore pump operation.
• The nextec Intelligence will also shut the motor down if:
►Pump temperature exceeds threshold parameters
►Input voltage is outside threshold parameters
►Rotor is locked

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.
Mounting peg
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.
Mounting bolt
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 minimum safe distances between the storage tank, dispenser, and power source.
Fueling Safety
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 This product is not suited for use with fluids intended for human consumption or fluids containing water. Materials of construction are not food
grade. Water will cause rust and corrosion in the pump housing. If water enters the pump, flush immediately with a petroleum product (gasoline,
diesel, kerosene, etc.) to eradicate residual water.
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.
NOTICE
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.
DANGER
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 GROUND.
• Keep nozzle in contact with container while
filling.
WARNING
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.

Tank Installation
NX25‑120 and NX25‑240 pumps mount 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 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).

Figure 1
TYPICAL TANK INSTALLATION
3" Min.
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 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.
ANTI-SIPHON INSTALLATION
Anti‑Siphon Line
Be certain the screen is properly seated in the indentation in the tank adapter before installing seal and tank adapter to the pump. Failure to
properly seat the screen can result in fluid leakage.

Servicing the Bypass Valve (Disassembly)
1. Using needle nose pliers, place the bypass valve retainer on top of the bypass valve spring. Carefully align the slot in 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).
Servicing the Bypass Valve (Reassembly)
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 (Figure 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 (Figure 2 & 3).

Intelligent Tones
Your nextec 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pumps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,
arrowspointingdown(↓) indicate low tones. Conditions listed in BOLD are not field serviceable, and require the pump to be returned to the manufacturer.
3-Tone Faults (Application / Installation faults)
Tones Condition Solution
↑ ↓ ↓ Low input voltage (auto shut‑off) Check input wiring gauge, length, and connections
↑ ↓ ↑ High input voltage (auto shut‑off) Check incoming voltage
↓ ↑ ↑ Locked rotor (auto shut‑off) Turn switch off and inspect rotor and vanes*
↓ ↑ ↓ Priming / Suction / Lift failure Check for leaks in suction tube, inlet connections, inside tank plumbing restrictions, excessive vertical suction lift,
empty tank
4-Tone Faults (Hardware faults)
Tones Condition Solution
↓ ↑ ↑ ↑ Hardware fault (auto shut-off) Troubleshoot as described below**
↓ ↑ ↓ ↓ Hardware over temperature (auto shut‑off) Turn switch off and allow pump to cool*
↓ ↓ ↑ ↑ Motor over temperature (auto shut‑off) Turn switch off and allow pump to cool*
↓ ↓ ↑ ↓ Motor overvoltage (auto shut-off) Troubleshoot as described below**
↓ ↓ ↓ ↑ Motor undervoltage(auto shut-off) Troubleshoot as described below**
*This condition will shut the motor off. To restart the motor, cycle the switch off, then back on, or cycle power to motor.
** Prior to returning pump to place of purchase, perform this procedure: cycle the switch off and disconnect power for at least one minute. Reconnect power, and cycle
theswitch back on. Verify proper pump operation. If this procedure does not restart the pump, or if you have additional questions, contact Technical Support at

Caractéristiques exclusives de la pompe nextec
La pompe de transfert de carburant nextec se comporte différemment des pompes non intelligentes au démarrage et durant la marche. Gardez les points suivants à l’esprit lorsque vous
commencerez à utiliser votre pompe intelligence nextec et que vous apprendrez à vous en servir.
• Au démarrage, il se peut que la pompe monte brièvement en régime puis redescende jusqu’à une sorte de ralenti, alors qu’elle s’adapte à la charge détectée. C’est un
comportement normal et la pompe reste à bas régime jusqu’à ce qu’on serre la gâchette du pistolet de distribution pour faire circuler le liquide.
• Lorsqu’on serre la gâchette du pistolet pour commencer à pomper, le microprocesseur dans la pompe détecte le changement et augmente le régime de la pompe en fonction de la charge.
Il n’est pas rare que le régime de la pompe varie durant la marche. Si les paramètres de fonctionnement changent, par exemple lorsqu’on augmente ou qu’on diminue le débit à
travers le pistolet, l’électronique de commande du moteur détecte ces changements et ajuste le régime du moteur de façon à obtenir un rendement optimal.
• Si la pompe détecte une situation qui est en dehors des paramètres normaux d’exploitation (faible tension d’entrée, par exemple), elle produit une série de tonalités pour signaler
le problème et aider à le diagnostiquer. Pour plus de détails sur cette fonctionnalité, voir la section «Avertisseur Intelligent Tones» du Guide de dépannage à la page 14.
• La pompe nextec est à service continu, à savoir qu’elle n’a pas besoin d’être mise à l’arrêt et au «repos» après une durée d’utilisation particulière. Cela permet d’effectuer du
ravitaillement d’un réservoir à l’autre sans devoir mettre la pompe à l’arrêt. La commande intelligente nextec prévoit toutefois une mise à l’arrêt automatique de la pompe au bout de 20
minutes en mode de dérivation (sans distribution de liquide). Cette fonction permet d’éviter une consommation électrique inutile et une usure excessive de la pompe, au cas où on oublierait
de la mettre à l’arrêt. Si la pompe s’éteint d’elle-même sous ces conditions, il suffit de mettre l’interrupteur d’alimentation en position d’arrêt puis de marche pour redémarrer la pompe.
• La commande intelligente nextec met également le moteur à l’arrêt si:
►La température de la pompe dépasse les valeurs de seuil
►La tension d’entrée est en dehors des valeurs de seuil
►Le rotor est bloqué

À propos de ce manuel
Du concept initial jusqu’à la fabrication finale, votre pompe Fill-Rite est construite pour vous offrir des années d’utilisation sans problème. Pour assurer ces résultats et pour écarter les
risques de blessure ou de mort, il est impératif que vous lisiez entièrement ce manuel avant de tenter d’installer ou de faire fonctionner votre nouvelle pompe. Familiarisez-vous avec les
termes utilisés et les schémas et accordez une attention particulière aux sections mises en évidence comme suit :
DANGER Le câblage électrique doit être exécuté avec toutes les précautions de rigueur et en conformité avec le code de l’électricité en vigueur, NEC/ANSI/NFPA
70, NFPA 30 et NFPA 30A, comme il se doit en fonction de l’utilisation prévue de la pompe. Utiliser des conduits rigides filetés, des raccords étanches et
un joint conducteur s’il y a lieu. La pompe doit être correctement reliée à la terre. Si l’installation s’écarte des instructions du présent manuel, elle devra
être confiée à un électricien agréé. Une installation ou utilisation incorrecte de ce produit entraînera de blessures corporelles graves ou la mort!
DANGER Pour assurer la sécurité et le bon fonctionnement du matériel, il est essentiel de lire et de respecter toutes les mises en garde et précautions
suivantes. Le non-respect des instructions ci-dessous ou une installation ou utilisation incorrecte de ce produit entraîneront des blessures
corporelles graves ou la mort!
• NE JAMAIS fumer à proximité de la pompe ni utiliser la pompe à proximité de flammes nues lors du pompage d’un liquide inflammable! Cela peut
provoquer un incendie!
• Ne pas utiliser ce produit pour transférer des liquides dans un quelconque type d’avion.
DANGER Pour minimiser l’accumulation d’électricité statique et le risque d’explosion, utiliser uniquement un tuyau flexible à conducteur antistatique pour
le pompage de liquides inflammables et maintenir le pistolet de distribution en contact avec le récipient à remplir durant le remplissage. Les
étincelles et décharge d’électricité statique provoquent des explosions.
Informations sur la sécurité
Le moteur de la pompe est équipé d’une protection électronique contre la surcharge thermique; en cas de surchauffe, le moteur s’arrête. Une fois
que le moteur a refroidi, il est possible de couper et rétablir l’alimentation ou l’interrupteur pour réinitialiser cette fonction de sécurité et poursuivre
l’utilisation. La pompe ne redémarre pas avant d’avoir correctement refroidi.
ATTENTION
L’étanchéité des joints et raccords de tuyauterie filetés doit être assurée au moyen d’une pâte ou d’un ruban d’étanchéité adapté afin de minimiser
les risques de fuite. Les fuites de carburant présentent un risque d’incendie et d’explosion.

| SÉRIES NX25-120 ET NX25-240 MANUEL D’INSTALLATION ET D’UTILISATION
Une étincelle d’électricité statique peut se produire
lors du remplissage d’un récipient portable posé
sur une doublure de plateforme de camionnette
ou sur tout tapis de sol ou moquette de véhicule.
Cette étincelle peut produire une inflammation
explosive des vapeurs d’essence et provoquer des
BLESSURES GRAVES ou la MORT.
• DANGER D’EXPLOSION PAR ÉTINCELLE
D’ÉLECTRICITÉ STATIQUE.
• NE JAMAIS remplir des récipients portables
posés dans ou sur un véhicule.
• TOUJOURS POSER LES RÉCIPIENTS SUR
LE SOL.
• Maintenir le pistolet au contact du récipient
durant le remplissage.
AVERTISSEMENT
ATTENTION Ne pas utiliser de clapets antiretour ou clapets à
pied à moins qu’ils comportent une soupape de
surpression adaptée intégrée. On notera que les
clapets antiretour réduisent le débit.
Durant le remplissage d’un réservoir de carburant, l’air qu’il contient est refoulé par l’évent du réservoir sous forme de vapeurs qui, si elles s’accumulent, créent une atmosphère explosive. Pour
écarter le risque d’explosion des vapeurs accumulées, il est impératif de maintenir les possibles sources d’étincelles ou d’inflammation à des distances sécuritaires des vapeurs de carburant.
Le schéma ci-joint montre les distances minimales de sécurité entre la citerne de stockage, le distributeur et la source d’alimentation.
Sécurité du pompage de carburant
ATTENTION Ce produit ne convient pas à une utilisation avec des liquides prévus pour la consommation humaine ni avec des liquides contenant de l’eau. Ses
matériaux de fabrication ne sont pas de qualité alimentaire. L’eau provoque la rouille et la corrosion du corps de pompe. Si de l’eau pénètre dans la
pompe, la rincer immédiatement avec un produit pétrolier (essence, diesel, huile légère, etc.) pour éliminer tout eau résiduelle.
Prévoir un filtre Fill-Rite à la sortie de la pompe pour éviter de transférer toute matière étrangère vers le réservoir de carburant. Les matières
étrangères peuvent endommager le matériel ravitaillé.
Les vapeurs accumulées durant le pompage de carburant créent une atmosphère explosive. Il est IMPÉRATIF que toutes sources possibles
d’inflammation soient déplacées jusqu’à une distance sécuritaire ou éteintes. Les sources d’inflammation sont notamment (mais sans s’y
limiter) les flammes nues, les cigarettes, les décharges d’électricité statique ou les contacts électriques susceptibles de produire une étincelle.
L’inflammation de vapeurs explosives provoque une explosion, un incendie et des blessures graves, voire mortelles.

Pose de la gaine de pistolet
Monter la gaine de pistolet à l’aide de la vis de fixation fournie. On notera que la vis se
place dans le trou le plus proche de l’ouverture du pistolet et que la gaine se place ensuite
de telle manière que le picot sur la surface de montage de la pompe s’engage dans le
deuxième trou supérieur de la gaine. Cela assure le bon alignement du pistolet lorsqu’il
est placé dans la gaine.
Vis de fixation
Installation
Les pompes NX25 120 et NX25-240 sont conçues pour offrir plusieurs configurations de
montage différentes, soit sur bonde, soit sur socle, telles que sur une citerne plate-forme.
Indépendamment du type de montage, toutes les citernes doivent être correctement aérées.
Picot de fixation
Montage sur socle
Le socle de fixation est boulonné à la base de la pompe à l’aide des vis à tête six pans
creux fournies. Monter le socle avec les brides de boulonnage à l’intérieur des pattes de
fixation de la pompe comme sur l’illustration. Serrer à un couple de 5,6Nm (50po-lb)
avec une clé hexagonale de 4mm.
