NOTICE
DO NOT
attempt to connect fire hydrant discharge to
the suction side of the pump as a water source to fill
the tank. The high psi discharge of the fire hydrant will
damage the pump casing.

MUST BE
primed. This
is accomplished by removing the Pump Fill Cap and
filling the Pump Casing with water and then re-securing
the fill cap.
