INSTALLATION AND OPERATION MANUAL 3 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 reponds to the load it senses.
| NX25-DDC SERIES DC FUEL TRANSFER PUMP 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, light oil, etc) to eradicate residual water.
INSTALLATION AND OPERATION MANUAL IMPORTANT! Do not use check valves or foot valves; valves reduce rate of flow and performance of the pump. 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.
| NX25-DDC SERIES DC FUEL TRANSFER PUMP Anti-Siphon Device NX25-DDC pumps come 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.
INSTALLATION AND OPERATION MANUAL 7 DC Power Connection DANGER! Be certain the switch is “OFF” prior to connecting the power cables to the power source or installing the cable into the pump to prevent unexpected starting of the motor. Unexpected motor start can cause unintended discharge of fuel, creating an explosion and fire hazard. Note that the switch does not interrupt power to the motor; it triggers a relay that tells the motor to turn on.
| NX25-DDC SERIES DC FUEL TRANSFER PUMP Operational Safety DANGER! DO NOT use pump in enclosed areas when pumping hazardous or explosive fluids. Pumping area should be well ventilated. Concentrated vapors in an enclosed area are noxious and highly explosive! WARNING! NEVER disconnect the power cable from the pump while pump is switched on or connected to a power source. ALWAYS switch the pump off and disconnect all the clamps from the power source PRIOR to disconnecting the power cable from the pump.
