Rotation.
Check the direction of the rotation of the pump to be sure that it
agrees with direction indicated on the rotation plate. If the direction
of the rotation is incorrect, consult the following instructions.
F o r a 3 phase, exchange any two incoming wire leads. F o r a 1
phase, follow the connection name plate on the motor. All pump units
should rotate clockwise when viewing from the motor end of the
pump. Securely install the pump on a firm footing to make sure the
pump will not move due to vibration.
Suction System.
Use a suction line that is the same size as the pump
port.
Using a suction line smaller than the pump port size
can cause internal damage to the pump. Horizontal
suction lines should slope up to the pump to prevent
trapped air pockets. Support the weight of the suction line
by installing an adjustable stand, pipe clamp or a floor
flange.
