Operation 5

1.The shaft seal depends on water for lubrication. Do not operate the pump unless it is submerged in water; running it dry may damage the seal.

2.If the pump overheats, an automatic-reset ther- mal protector cuts off the power and stops the motor before it can be damaged. The motor will automatically restart when it cools. If the protec- tor trips repeatedly, unplug the pump, remove it from the sump, and check it for the cause of the difficulty. Low voltage, long extension cords, clogged impeller, very low lift, a plugged or frozen discharge pipe, etc., can all cause cycling and overheating.

3.This pump will not remove all the water in the sump. If you are running the pump manually and water stops coming out of the discharge, the pump has probably run dry. Shut it off immedi- ately and check the water level.

Figure 7 – LIFT: Lift is the vertical distance the pump actually lifts water.The higher the lift, the lower the flow.

NOTE: The friction caused by water running through the pipe will also, on longer pipe runs, reduce the flow.
