WARNING
Pressure Hazard. May result in personal injury or
death.
Prior to connection of hoses, caps or other closures
with pump intake or pump discharge connections,
relieve pressure by opening drains or bleeder valves.
!
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 even for a few minutes
completely closed it may heat the water enough to
scald someone when the valve is opened. Overheat-
ing 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 over-
heating, opening a discharge valve may be unneces-
sary.
Pumping from Hydrant or in Relay
After Pumping
NOTE: Limit inlet pressure to 150 psi (10.3 bar) if
possible. The pump will operate properly with higher
intake pressure but it will accelerate mechanical seal
wear.
1. Engage pump drive.
2. Open intake, hydrant and other valves as necessary
to allow water to enter pump.
NOTE: Bleeder valves should be used while fill-
ing a hose connected to an intake with water.
3. Open discharge valves and accelerate engine to ob-
tain desired discharge pressure and capacity.
4. Set relief valve or other pressure governing device to
desired pressure.
1. Disengage pump drive.
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 wa-
ter for several minutes to remove all traces of impuri-
ties.
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.
4. Close all drains and install intake and discharge
caps.
5. If truck is equipped with a priming pump, operate it
until fluid is discharged from priming pump discharge
pipe. Also check fluid level in priming tank, and refill
if necessary.
CAUTION
Freezing water hazard. May cause damage to
the pump.
If the pump is exposed to freezing temperatures,
drain all water from pump, lines and accessories.

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 or bleeder valves.
CAUTION
Do not attempt to pump more water than is
available from hydrant or relaying pumper. Al-
ways make sure compound gage reading stays
above zero.
