Operation - Briggs & Stratton WP20 Manual Del Operario

Operation

If you have any problems operating your water pump, please
contact the store at which you purchased the unit or any
authorized dealer.
Safe Operating Considerations
Clearances and Air Movement
WARNING Exhaust heat/gases could ignite
combustibles, structures or damage fuel tank
causing a fire, resulting in death, serious injury and/
or property damage.
• Keep at least 1.5 m (5 ft) of clearance on all sides of water
pump including overhead.
Place water pump outdoors in an area that will not
accumulate deadly exhaust gas. DO NOT place water pump
where exhaust gas could accumulate and enter inside or be
drawn into a potentially occupied building. Ensure exhaust
gas is kept away from any windows, doors, ventilation
intakes, or other openings that can allow exhaust gas to
collect in a confined area. Prevailing winds and air currents
should be taken into consideration when positioning water
pump.
WARNING Running engine gives off carbon monoxide,
an odorless, colorless, poison gas.
Breathing carbon monoxide could result in death,
serious injury, headache, fatigue, dizziness,
vomiting, confusion, seizures, nausea or fainting.
• Operate water pump ONLY outdoors.
• DO NOT start or run engine indoors or in an enclosed
area, even if windows and doors are open.
• Keep exhaust gas from entering a confined area through
windows, doors, ventilation intakes, or other openings.

What is "Head"?
Head refers to the height of a column of water that can be
delivered by the discharge of the pump.
Suction Head (A) is the vertical distance between the center
of the pump and the surface of the liquid on the suction side
of the pump. May also be referred to as "suction lift". The
atmospheric pressure of 1 bar (14.5 psi) at sea level limits
suction head lift to less than approximately 8 m (26 ft) for
any pump.
Discharge Head (B) is the vertical distance between the
pump's discharge port and the point of discharge, which is
the liquid surface if the hose is submerged or pumping into
the bottom of a tank.
Total Head (C) is the sum of the suction head value plus the
discharge head value.
As water pumping height increases, pump output decreases.
The length, type, and size of the suction and discharge
hoses can also significantly affect pump output.
It is important for the suction operation to be the shorter part
of the total pumping action. This will decrease the priming
time and improve pump performance by increasing the
discharge head.
See Specifications for maximum head values.
