CHAPTER 12

OPERATION

SAFE OPERATING PRECAUTIONS
To safely realize the full potential of this pump, you need a complete understanding of its operation and a certain
amount of practice with its controls.
Before operating the pump for the first time, please review the IMPORTANT SAFETY INFORMATION on page 9 and the
chapter titled CHECK BEFORE OPERATION.
For your safety, avoid starting or operating the engine in an enclosed area, such as a garage. Your engine' s exhaust
contains poisonous carbon monoxide gas which can collect rapidly in an enclosed area and cause illness or death.
Pump only fresh water that is not intended for human consumption. Pumping flammable liquids, such as gasoline
or fuel oils, can result in a fire or 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 with the least self-priming time.
As head (pumping height) increases, pump output decreases. The length, type, and size of the suction and discharge
hoses can also significantly affect pump output.
Discharge head capability is always greater than suction 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 a 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.
Do not use a hose smaller than the pump' s suction port size. Minimum hose size: 1.5 in (40 mm)
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.
