Beforeoperatingtheenginefortherst
time, please review the IMPORTANT SAFETY
INFORMATION and BEFORE OPERATION.
Pump only water that is not intended for human
consumption.Pumpingammableliquids,such

explosion, causing serious injury. Pumping sea
water, beverages, acids, chemical solutions or
any other liquid that promotes corrosion, can
damage the pump.
PUMP PLACEMENT
For best pump performance, place the pump
near the water level, and use hoses that are
no longer than necessary. That will enable the
pump to produce the greatest output.
As head (pumping height) increase, pump
outputdecreases.Maximumheadspecications
and pump performance curves are shown in
the table on page 2. The length, type and size
of the suction and discharge hoses can also
signicantlyaffectpumpoutput.
Discharge head capability is always greater
than such head capability. So it is important
for suction head to be the shorter part of total
head.
Minimizing suction head (placing the pump
near the water level) is also very important for
reducing self-priming time. Self-priming time
is the time it takes the pump to bring water
the distance of the suction head during initial
operation.
SUCTION HOSE INSTALLATION
Use the commercially available hose and hose
connector with the hose clamp provided with
the pump. The suction hose must be reinforced
with a non-collapsible wall or braided wire
construction.
The suction hose should be no longer than
necessary. Pump performance is best when the
pump is near the water level and the hoses are
short.
Use a hose clamp to securely fasten the hose
connector to the suction hose in order to
prevent air leakage and loss of suction. Verify
that the hose connector sealing washer is in
good condition.
Install the strainer (provided with the pump) on
the other end of the suction hose, and secure
it with a hose clamp. The strainer will help to
prevent the pump from becoming clogged or
damaged by debris.
Securely tighten the hose connector on the
pump suction port.
