5.2.1 — Clearances and Air Movement
Running engine gives off carbon monoxide,
an odorless, colorless, poisonous gas.
Breathing carbon monoxide can cause head-
ache, fatigue, dizziness, vomiting, confusion,
seizures, nausea, fainting or death. For more
information, reference the CO warnings in the
"Safety" section.
Place water pump outdoors in an area that will not accu-
mulate deadly exhaust gas. NEVER 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, ven-
tilation 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 posi-
tioning water pump (Figure 5-1).
• Operate water pump ONLY outdoors.
• Keep exhaust gas from entering a confined area
through windows, doors, ventilation intakes, or other
openings.
• NEVER start or run engine indoors, in a vehicle or in
an enclosed area, EVEN if windows and doors are
open.
Exhaust heat/gases can ignite combus-
tibles, structures or damage fuel tank
causing a fire.
• Keep at least 5 ft. (152 cm) clearance on all sides of
water pump including overhead.

OCATION
Figure 5-1. Building Clearances
Place the pump on a level surface free from any obstruc-
tions or potential hazards. The pump should be placed
close to the water level to ensure maximum performance.
Pump output will be affected by the type, length, and size
of the suction and discharge hoses. The pumping height,
total head, is the distance from the water level to the
point of discharge (Figure 5-2). As this distance
increases, the pump output decreases. The discharge
capacity is greater than the suction capacity, therefore it
is important to keep the suction head less than the dis-
charge head. The time required to draw water from the
source to the pump (self-priming time) can be decreased
by minimizing the suction head.
