PUMP CORD
Run the wires from both pumps to the bottom of
the control box by means of one of the methods
described in your pump or basin installation
instructions. A hole must be cut into the control
box (use the same procedure as that described for
incoming power supply lines).
Connect red, white and black wires to terminals
marked M1, M2 and M3 (for 3 phase applications),
or connect the red, white and black wires to
terminals marked R, W and B (for 1 phase
applications). Fasten green wire to ground lug.
WGL pumps may have an additional brown wire in
the pump cord. This is for the seal leak probe and it
should be connected to the terminal strip in the
control box. See wiring diagram for the proper
terminal connections.
NOTE: On 3 phase installations check for proper
pump rotation. See the “ROTATION OF 3
PHASE PUMPS” section in this manual.
FLOAT CORDS
See basin instructions for the proper depth at which
to set the floats. Strip the float cord wires

", twist
strands together, and connect black and white
wires to terminal strip in the control box. See wiring
diagram for proper terminal connections.
CONNECTING PUMPS AND FLOATS TO CONTROL BOX
OPERATING PUMPS
1. Make sure that all wires are inside the control box
and not in a position to be pinched or shorted
when the door is closed.
2. Turn on power to the control box.
3. Turn hand-off-auto switches to the “HAND”
position. The pumps should start and the pump
run lights should come on. (On duplex panels,
this should be done for both pumps).
4. To put into service, put the hand-off-auto switch
in the “AUTO” position. (On duplex panels, this
should be done fore both pumps). See basin
instructions.
5. If unit does not operate as described, see
troubleshooting chart.
NOTE: Addition of electrical components and
circuitry to this unit is expressly forbidden
unless written factory authorization is
obtained. Failure to do so will result in
warranty cancellation.
ROTATION OF THREE PHASE PUMPS
IMPORTANT
Rotation of three phase pumps must be established
by one of the two methods described below.
CAUTION
Keep hands and feet clear of impeller when
checking rotation. Be sure to disconnect power to
the control box while handling pumps. Make sure
pump is wired and readied for rotation test before
the control box is energized.
1. Before positioning pump in basin, run wires to
control box. Lay the pump unit on its side and
secure so that the starting torque of the motor
will not cause the pump to roll. Energize the
pump by turning the circuit breaker on and the
hand-off-auto to “HAND”. The rotation should be
counterclockwise as observed facing the bottom
of the pump.
If you do not get the proper rotation, disconnect
the power to the control box and change the
position of any two of the black motor leads in
the terminal blocks.
2. Install the pump in the basin and run in some
water so the pump can operate. Energize the
pump by turning the circuit breaker on and the
hand-of-auto switch to “HAND”. Let the pump
pull the water down in the basin, and when the
water reaches the bottom of the pump the
rotation of the water can be observed. The water
should rotate in a clockwise direction if the
pump rotation is correct.
If you do not get the proper rotation, disconnect
the power to the control box and change the
position of any two of the black motor leads in
the terminal blocks.
