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

Safety Information
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!
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.
