OPERATION
FILLING THE WATER TANK (FIRE HYDRANT)
1. Remove the water tank cap.
2. Attach hydrant adapter to fire hydrant if necessary.
3. Attach fire hydrant discharge hose between the 2" steel
water tank pipe QD port and the fire hydrant.
4. Make sure there are no bends or sharp kinks in the
hose between the fire hydrant and water tank fill port.
5. Slowly open the hydrant valve. Water tank should
begin to fill.
6. Fill the water tank to the desired level and close the
fire hydrant valve.
7. Remove fire hydrant discharge hose and allow the hose
to drain. Remove the hydrant adapter.
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.
NOTICE
Prior to engine start, the pump
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.
