INSTALLATION AND OPERATION MANUAL

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 (low input voltage, for example), 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

About This Manual 

From initial concept and design through its final production, your Fill‑Rite pump is built to give you years of trouble‑free use. To ensure it provides that service, and to avoid injury or 
death, 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 areas with the following labels:

Safety Information 

DANGER!

 Emphasizes an area in which personal injury or even 

death 

will 

result from failure to follow instructions properly. 

Mechanical damage may also occur.

DANGER!

 Electrical wiring should be performed with extreme caution and in compliance with local, state, and national electrical code NEC/ANSI/NFPA 70, NFPA 

30, and NFPA 30A, as appropriate for the intended use of the pump. Threaded rigid conduit, sealed fittings, and conductor seal should be used where applicable. 
The pump must be properly grounded. It is recommended that a licensed electrician perform the installation. Improper installation or use of this product will result 
in serious bodily injury or death!  

DANGER! 

To ensure safe and proper operation of your equipment, it is critical to read and adhere to all of the following safety warnings and precautions. Failure to 

follow instructions below, improper installation, or use of this product, will cause serious bodily injury or death!

• 

NEVER

 smoke near the pump, or use the pump near open flames when pumping a flammable liquid! Fire may result!

•  This product shall not be used to transfer fluids into any type of aircraft. 

DANGER! 

To minimize static electricity build up and possible explosion, use only static wire conductive hose when pumping flammable fluids, and keep the fill 

nozzle in contact with the container being filled during the filling process. Spark / static discharge may cause explosions. 

WARNING! 

Threaded pipe joints and connections should be sealed with the appropriate sealant or sealant tape to minimize the possibility of leaks. Leaking fuel may 

cause the potential for fire and explosion.

CAUTION!

 The pump motor is equipped with electronic protection from thermal overload; if overheated, the motor will slow down. After the motor has cooled, you may cycle 

power or the switch to reset this safety feature and continue use. The pump will not restart until properly cooled.

CAUTION!

 Failure to observe a “Caution” may cause damage to 

the equipment. 

WARNING!

 Emphasizes an area in which personal injury or even 

death 

may

 result from failure to follow instructions properly. 

Mechanical damage may also occur. 

IMPORTANT! 

These boxes contain information that illustrates 

a point that may save time, or be key to proper operation, 
or clarifies a step.
