Operation
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.

the pump actually lifts water.The higher
the lift, the lower the flow.
