OPERATION
USING THE WATER PUMP
Safe Operating Considerations
Clearances and Air Movement
The water pump must be at least 5 ft. (152 cm) from
structures having combustible walls and/or other
combustible materials. Leave at least 3 ft. (92 cm) all around
water pump including overhead, for adequate cooling,
maintenance and servicing.
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
(Figure 8). Prevailing winds and air currents should be taken
into consideration when positioning water pump.
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 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 14.7 psi at sea level limits suction
head lift to less than approximately 26 feet for any pump.
Discharge Head 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 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.
Suction head is a maximum of 25 feet and discharge head
should be a maximum of 81 feet.Total head can not be
more than 106 feet (Figure 9, next page).
Move Water Pump to Safe
Operating Location
For best pump performance, locate the pump on a flat, level
surface as close as possible to the water to be pumped.
Secure water pump to avoid tipover. Use hoses that are no
longer than necessary.
IMPORTANT: Direct open end of discharge hose away
from home, electrical devices or anything not desired to
get wet.

Typical Water Pump Shown
• Operate water pump ONLY outdoors.
• Keep exhaust gas from entering a confined area through
windows, doors, ventilation intakes or other openings.
• DO NOT operate water pump inside any building, confined
area or enclosure, such as basements, garages or a similar
location, even if doors or windows are open.
Running water pump gives off carbon monoxide,
an odorless, colorless, poison gas.
Breathing carbon monoxide may cause nausea,
fainting or death.
WARNING
WHEN OPERATING EQUIPMENT
• This water pump is not for use in mobile equipment or
marine applications.
• DO NOT tip engine or equipment at angle which causes fuel
to spill.
• Secure water pump. Loads from hoses may cause tipover.
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
