Before installing a pump, check the pump rotation to insure that wiring has been
connected properly to power source, and that the green lead of power cable (See wiring
diagram), is connected to a valid ground, momentarily energize the pump, observing the
directions of kick back due to starting torque. Rotation is correct if kick back is in the
opposite direction of rotation arrow on the pump casing. If rotation is not correct,
switching of any two power leads other than ground will provide the proper rotation.
DO NOT PLACE HANDS IN PUMP SUCTION WHILE CHECKING
MOTOR ROTATION. TO DO SO WILL CAUSE SEVERE PERSONAL INJURY.
Three phase pumps have integral motor overload protection. It is recommended that all
three phase pumps using a motor starting device also incorporate motor overload
protection. Pumps must be installed in accordance with the National Electrical Code
and all applicable local codes and ordinances. Pumps are not to be installed in locations
classified as hazardous in accordance with National Electrical Code, ANSI/NFPA 70.
