Turning On The Pump

If all of the pump's electrical requirements have been met, place the circuit breaker or power ON/OFF switch in the ON position.

The CB3 control box has an operation switch located on the front cover. This switch has 3 positions, AUTO, MANUAL and OFF. The AUTO position allows the pump to run in an un-attended mode.

The MANUAL position will let the pump run without the float switches controlling the pump. When in the manual mode be careful not to let the pump run dry. Severe damage to the pump may occur if it is allowed to run dry. NEVER let the pump run dry.

Manual Operation

1.For manual operation of the pump, place the 3-position operation switch (Figure Figure 13) on the control box in the MANUAL position.

Figure 13. Manual-Off-On SW. (Man. Position)

2.The AC power indicator lamp (Figure 14) should be lit (ON).

3.Wait a few seconds and water should begin to flow from the discharge hose.

4.If water is not flowing from the discharge hose or not flowing freely after a few minutes, remove the power from the pump and check the system for leaks.

5.To stop the pump from pumping, place the operation switch in the OFF position.

Automatic Operation

1.For unattended operation of the pump, place the operation switch (Figure 15) in the AUTO position.

Figure 15. Manual-Off-On SW. (AUTO Position)

2.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.

3.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.

Shut-Down

1.Place the 3-position operation switch on the control box in the OFF position (Figure 16).

Figure 16. Manual-Off-On SW. (OFF Position)

2.Verify that the control box power ON light is OFF.

3.Remove the power from the pump by turning off the circuit breaker or switch that provides power to the pump. Remember to make sure that hands are dry (not wet), and feet are not standing in water when removing or disconnecting power from the pump.

4.Using the lifting rope, lift the pump up from its current position. Remove the discharge hose from the discharge port on the pump.

5.Remove all power cables and float switches from the control box. Place cables and float switches in a suitable container where they will not get damaged.
