Full Load Current (FLC) Amps Dial A Setting

1.Set dial A pointer (Figure 16) to 10.5. This setting represents the running amps of the pump. This information can be located on the pump's nameplate

Reset Dial Setting

1.Depending on the application, Set RESET dial B pointer (Figure 16) to either AUTO or MAN.

Manual Operation

1.From the voltage source set the circuit breaker or quick disconnect switch to the ON position.

2.For manual operation of the pump, place the 3-position operation switch (Figure 17) on the control box in the MANUAL position.

Figure 17. Manual-Off-On SW. (Man Position)

3.Verify that the ON indicator (Figure 18) on the control box is LIT. This means that power is being supplied to the control box.

Figure 18. Control Box Power ON Indicator

4.In the manual mode the pump will run continuously. Pay close attention when running the pump in this mode. Severe DAMAGE to the pump may occur if pump is not immersed in water.

Automatic Operation

1.From the voltage source set the circuit breaker or quick disconnect switch to the ON position.

2.Make sure float switches have been connected to the control box. References Figures 9,10 and 11.

3.For automatic operation of the pump, place the 3-position operation switch (Figure 19) on the control box in the AUTO position.

Figure 19. Manual-Off-On SW. (AUTO Position)

4.In the AUTO mode the pump will run as long as there is a sufficient amount of water for the start float switch to be activated. This water level is determined by the setting of the float switches.

The stop float switch contacts will open when the water level is low and power will be removed from the pump's motor.

5.Once the water level has risen back to the appropriate level the start float switch contacts will close and power will be restored to the pump's motor.
