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. The pump must be properly grounded. If installing in deviation of this manual, a licensed
electrician must perform the installation. Improper installation or use of this product could 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!
• DO NOT use the pump near flammable liquids! Fire can result!
• This product shall not be used to transfer fluids into any type of aircraft.
WARNING! Threaded pipe joints and connections should be sealed with the appropriate sealant or sealant
tape to minimize the possibility of leaks. Leaking fluids may cause a hazard.
WARNING! On Fill-Rite DEF pumps equipped with AC motors, the pump motor is equipped with thermal
overload protection. If overheated, the motor will shut off to prevent damage to the windings. If this happens,
TURN THE PUMP OFF! When the motor cools, it will restart without warning if the power is on.
CAUTION! This product is not suited for use with fluids intended for human consumption. Materials of
construction are not food grade.
About Diesel Exhaust Fluid (DEF / AdBlue)
The FIll-Rite DEF pump is designed to pump AUS32 (Aqueous Urea Solution 32.5%), better known as Diesel Exhaust
Fluid, often called "DEF", or "AdBlue".
DEF / AdBlue is used by modern diesel engines which are equipped with an SCR (Selective Catalytic Reduction)
system. The common misconception is that it is an additive to the fuel, but DEF / AdBlue never comes into contact with
the fuel. DEF / AdBlue is carried onboard the vehicle in its own storage tank. It is injected into the exhaust gases as a
post combustion process through an SCR (Selective Cataltic Reduction) where it breaks harmful NOx (Nitrous Oxide)
emissions down into mostly nitrogen and oxygen.
Because the specific purity of the DEF / AdBlue solution is critical to the catalytic reaction, the Fill-Rite DEF pump is
designed to maintain the integrity by using components made of materials that will not taint or alter the solutions chemical
structure.
IMPORTANT! To maintian the purity of DEF / AdBlue, it is important the dispensing system is a "closed loop",
or sealed system. DEF / AdBlue will crystalize on contact with oxygen, so having sealed containers, sealed
lines and equipment, and a dispensing nozzle imersed in water are all paramount to maintining the integrity of
the DEF / AdBlue solution.
IMPORTANT! After initial assembly and installation, flush the entire dispensing system by pumping 5 – 10
gallons of DEF through it. This purges the system of air, and insures any impurities that may have been in
the system are washed out. Dispose of the DEF used to flush the system using approved DEF handling
procedures; do not return the fluid to the drum or tote, or use it in a vehicle.
