Operating Instructions
Transmission Operation
Because of the variety of transmissions available for these pumps, the methods of operating them are not explained in this
section. For information on Waterous transmissions, refer to transmission operation instructions.
Pumping from Water Tank
WARNING
!
Pressure Hazard. May result in personal injury.
Prior to connection or removal of hoses, caps or other
closures with pump intake or pump discharge connec‐
tions, relieve pressure by opening drains.
WARNING
!
Scalding Water Hazard. May result in serious burns.
When operating the pump, be sure to open at least
one discharge valve slightly to prevent the pump from
overheating. If the pump runs for a few minutes com‐
pletely closed, it may heat the water enough to scald
someone when the valve is opened. Overheating can
damage the packing, seals and other pump parts. If
the apparatus builder has installed a by-pass system
or other provision designed to prevent overheating,
opening a discharge valve may be unnecessary.
WARNING
!
Unexpected Truck Movement. May result in seri‐
ous personal injury or death.
Failure to properly shift transmission in accordance to
the transmission operating instructions may result in
unexpected truck movement which may result in seri‐
ous personal injury or death.
1.
Engage pump in accordance with transmission
instructions.
2.
Open valve(s) in piping between water tank and pump
intake and at least one discharge valve.
3.
Allow about 30 seconds for water to flow into pump.
NOTE: Priming the pump may be necessary
because of air trapped in piping.
4.
Accelerate engine to obtain desired discharge
pressure and capacity.
5.
Set relief valves or other pressure governing device to
desired pressure.
NOTE: For extra pressure stage pumping
instructions, see page 8.
After Pumping
WARNING
!
Pressure Hazard. May result in personal injury or
death.
Prior to removal of hoses, caps or other closures with
pump intake or pump discharge connections, relieve
pressure by opening drains.
1.
Disengage pump drive in accordance with
transmission instructions.
2.
If pumping anything but clean water, remove all intake
and discharge caps, open all valves and open all
drains. Flush entire system with clean, fresh water for
several minutes to remove all traces of impurities.
3.
If pump is kept full of water when not in use, make
sure water is clean and non-corrosive. Make sure the
pump is completely full or completely drained - never
partially full.
CAUTION
If the pump is exposed to freezing temperatures, drain
all water from pump, lines and accessories.
4.
Close all drains and install intake and discharge caps.
