Checking the direction of rotation
The direction of rotation and the flow direction are indicated by arrows on the pump. The direction of ro-
tation of the motor specifies the direction of rotation of the pump. That is to say, the fan impeller of the
motor must rotate in the direction in which the arrow on the pump is pointing to indicate direction of ro-
tation.
For information on checking the direction of rotation please refer to the pump operating instruc-
tions.
