Three Phase Installation
Three phase pumps are nonautomatic. To operate
automatically, a control panel is required. Follow the
instructions provided with the panel to wire the system.
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 cord (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, should provide
the proper rotation.
Refer to the wiring diagram supplied with specific
electrical control panel for correct cable termination
locations.
NOTE:
Sensor cable includes 5 leads; 2 leads for thermal sensor, 2 leads for moisture sensor, and a green ground lead. Sensor wire colors are as shown.
