INSTALLATION
The pump should be located on a fi rm level surface as close as
possible to the source of the water to be pumped. If possible, the
unit should be bolted down and blocked to prevent creeping due
to vibration. A suction hose should run from the pump directly to
the water; ensure that the hose rises continuously from the water
to the pump with no kinks, which could become an air lock. A foot
valve must be installed at the bottom of the suction line. Use only
suction piping and foot valve sizes, that have the same pipe size
(or larger) as the pump suction tapping.

OPERATION - PRIMING THE PUMP
WARNING:
DO NOT RUN THE PUMP BEFORE PRIMING IT; THE SEAL AND IMPELLER COULD BE
PERMANENTLY
DAMAGED.
1)
Before starting this pump, check the engine
oil level
and
refi ll if necessary.
2)
These pumps are not self priming. A foot valve must be in-
stalled on the suction line as shown in Fig. 1. Fill the pump
casing and the suction line with water (see installation dia-
gram). Do not run the pump dry, or seal damage will occur.
Start the engine and allow it to run 1/2 a minute. If the
pump does not deliver water by this time, stop the engine
and repeat the priming operation. Several attempts may be
necessary to expel air in the suction line.
MAINTENANCE
WARNING
•
Review chemical manufacturer's safety precautions before
handling.
•
Make sure all connections are tight.
•
Do not breathe or ingest fumes or chemicals.
•
Never use with fl ammable fl uids.
•
Turn off engine before servicing.
•
If fuel is spilled, avoid creating any source of ignition until the
fuel vapors have been cleaned up and removed.
1)
Check engine oil level regularly
. Refer to the manufacturer
instruction booklet for maintenance.
2)
To disassemble the pump for periodic cleaning:
a)
Disconnect the suction and discharge hoses.
b)
Remove four bolts and take off casing.
c)
Unscrew the impeller in a counter clockwise direction.
d)
Slip the seal and sleeve off the engine shaft.
e)
Remove adapter from the engine, being very careful not
to damage the ceramic seat.
f)
Inspect the ceramic seat, if it needs replacing, press it
out of the adapter from the engine side.
3)
To
reassemble:
a)
Clean all parts thoroughly before reassembly. Lubricate
the rubber cup of the ceramic seat with soapy water
and push it into the adapter. Make sure that the smooth
surface of the seal faces out.
b)
Assemble the adapter to the engine, being careful not to
damage the ceramic seat.
c)
Lubricate the inner rubber ring of the rotating portion of
the seal and slip it onto the sleeve and then slip the as-
sembly onto the engine shaft with the rotating seal face
toward the ceramic seat. Make sure that the seal face
on the rotating seal is in contact with the ceramic seat.
d)
Screw on the impeller. Install a new gasket and assem-
ble the casing using the supplied mounting hardware.
Use thread locking/sealing compound on casing bolts
to prevent leaks. Check to ensure that the impeller can
rotate freely in the casing.
e)
Reconnect pump to suction and discharge hoses.
f)
All models have a fl inger on the shaft. This fl inger must
not be removed, unless it needs to be replaced.
