IMPORTANT INFORMATION ON DEF "CRYSTAL LOCKED" ROTORS: DEF
will crystallize almost immediately upon contact with air; if air gets to the DEF in the
rotor cavity, it can crystallize the DEF and lock the rotor in place. If this occurs, the
following procedure will clear the vanes of crystals and return the pump to
operation:
1) Remove the strainer cover
2) Pour de-ionized water into the strainer opening; the DEF crystals will dissolve
instantly.
3) Reinstall strainer cover and torque to 50 inch lbs.
4) Pump at 5 - 10 gallons of DEF through the system to flush the water from the
pump.
Bold text indicates repairs that are not serviceable by the owner; pump must be returned to
the point of purchase for repairs.

compromise the integrity of the construction and will void any existing warranty and
certification (UL listing).
