CHECK ROTATION:
Before pump is put into operation, rotational direction
must be checked to assure proper performance of
pump. Refer to illustration below to varify proper
rotational direction for each model covered in this
manual.
Hazardous voltage. Can shock, burn, or
cause death. Disconnect power to pump before
servicing.
Do not attempt any wiring changes without first
disconnecting power to pump.
PRIMING:
Pump priming is the displacement of air with water in
the pump and suction piping. Pump MUST BE
completely filled with water when operating.
A self-priming pump only needs to be manually primed
at the first start-up. Once primed, under normal
conditions pump will reprime automatically at each
subsequent start-up.
To prime, remove plug from top of pump case and fill
case with water. Replace plug and start pump. Unit is
equipped with a flapper type check valve which will
open at start-up and allow pump to evacuate air from
the suction line. After several minutes of operation,
pump will be fully primed and pumping water. Priming
time will vary, depending on length and diameter of
suction line.
STARTING (Electric Motor):
NOTICE: Never run pump dry. Running pump without
water will overheat pump and damage internal parts.
Always make sure pump is primed prior to start-up.
NOTICE: Refer to maintenance section if pump has
packing for adjustment prior to start-up.
Prime pump by the above method. Turn on power to
pump. Slowly open discharge valve until desired flow
rate is achieved. Place the “Hand-Off-Auto” selector
switch in the “Auto” position. The pump will start
automatically when the pilot device signals the motor
starter.
STOPPING (Electric Motor):
Pump will stop automatically when the pilot device de-
energizes the motor starter. Turn the “Hand-Off-Auto”
selector switch to “Off” position if you want to stop the
pump while it is running.

ELECTRIC MOTORS:
Single Phase: Refer to wiring information on the
motor plate to obtain proper rotation.
Three Phase: If pump runs backwards, reverse any
two leads coming of incoming power (L1, L2, L3) until
proper rotation is obtained. Reverse L1 and L2, L2
and L3, or L1 and L3.
Pump running backwards - Centrifugal pumps will still
pump liquids, however, GPM and head will be a
fraction of the published performance.
ENGINE DRIVEN:
If engine is used for pump driver, check with engine
instruction and operation manual or engine
manufacturer to determine how rotation is defined,
then use above illustration for proper connection.
