line, pump casing, and discharge line up to the
level of supply.
3. Where the pump is operating with suction
lift and the suction line is equipped with a
foot valve, remove the priming plug from the
discharge tee (see Figures 5-8) and fill the
pump body and suction pipe completely with
water. No additional water will be needed for
subsequent start-ups unless the pump body is
drained.
4. After the pump is turned on it will require 2-5
minutes before all air is evacuated from the
suction line and water begins to flow. If there
is no water after 5 minutes, turn the pump off
and check the following:
5. Any air leaks on the suction line must be
eliminated.
6. Suction pipe inlet should be a minimum of 5
feet below the water level.
7. Total suction lift cannot be greater than 25 feet.
8. Any restrictions in the discharge pipe, such as a
closed valve must be eliminated.
NOTE: Unit must be full of liquid before operating.
Never run dry, or against a closed discharge. Dry
running or running unit against a closed discharge
will cause damage to the shaft seal. Do not pump
dirty water or abrasive liquids, otherwise the same
may occur as if running dry.
MOTOR ROTATION
1. Single phase models are one (1) rotation only
(counterclockwise when facing the pump
suction tapping) and cannot be reversed.

2. Proper rotation of pump impeller is critical for
three phase pumps. Pump motor should turn
counterclockwise (CCW) when facing pump
suction tapping. Momentarily “bump” (apply
power for less than a second) the motor to check
for proper rotation. To change rotation on three
phase units, interchange any two (2) incoming
line (power) leads.
