Seal Fail Sensor Wiring
The motor has integral moisture sensors that must be properly connected to a control panel with seal-fail
circuitry. The pump can be removed from service when moisture is detected in the seal-fail chamber. The
presence of water in this chamber energizes the seal leak warning light inside the control panel (if so
equipped with this option).
IMPORTANT: Improper wiring of the seal fail sensor to the control panel will void the warranty and
Class 1 listing.
NOTE: This is a warning light only and will not keep the pump from continuing to operate.
• Connect the red (W1) and orange (W2) moisture sensor leads to the seal terminal in the control
panel.
• Connect the green ground wire to ground inside the control panel.
Impeller Rotation
Risk of damage to pump or other equipment.
• Improper impeller rotation will result in damage to the pump. Rotation must be checked at installa-
tion.
1. Verify the disconnect switch is in the "Off" position.
2. Lay the pump on its side.
3. Verify the impeller rotates counterclockwise by briefly turning the disconnect switch to the "On" posi-
tion.
• Startup kickback rotation is also counterclockwise when viewed from the top of the suspended
pump.
4. To change rotation of 3-phase motors, interchange any two of the white, red, or black wires of the
pump at the disconnect box.
Level Sensing Controls
• Pump Off Control: Should be set to turn the pump off when the water level is at the top of the motor
housing. By setting the control at this point you are utilizing the liquid being pumped to help cool the
motor which improves the life expectancy of the motor.
• Pump On Control: Should be set to turn the pump on between 6" to 12" below the Lag/Alarm control
device. An optimum cycle for these products would be between 2 to 3 minutes of run time per cycle.
Lag/Alarm Control: Should be set between 6" to 12" below the inlet of the station. It is important to
•
note that no control device should ever be set above the inlet of any station.
