Determine Pump Rotation - Pentair BERKELEY Manual Del Usuario

Start-up • Determine Pump Rotation
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.
NOTICE: This pump rotates clockwise.
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 off incoming power (L1, L2, L3)
until proper rotation is obtained. Reverse L1 and L2,
or L2 and L3, or L1 and L3.

• Pump running backward - Centrifugal pumps will still
pump liquids, however, GPM and head (discharge
pressure) will be a fraction of the published
performance.
