Before Start-Up
Check Rotation:
Beforepumpisputintooperation,rotationaldirection
must be checked to assure proper performance of pump.
Refertoillustrationshownbelow.
Direction of pump rotation is determined by viewing
liquid end of pump from the back or shaft side, and not
from looking into the impeller eye or front of volute case.
A rotation direction arrow is cast into the pump body
and shows correct rotation.
Risk of electric shock. Can shock, burn or
kill. Disconnect power to pump before servicing. Do not
attempt any wiring changes without first disconnecting
power to pump.
• Single Phase Motors:Refertowiringinformationon
the motor plate to obtain proper rotation.
• Three Phase Motors: If pump runs backwards,
reverse any two leads coming off incoming power
(L1,L2,L3)untilproperrotationisobtained.Reverse
L1andL2,orL2andL3,orL1andL3.
• Pump running backward - Centrifugal pumps

NOTICE A motor protection device must be installed for
all three-phase pump motors.
