INSTALLATION/OPERATION
9. After piping, check valve and float switch have been installed, the
unit is ready for operation.
10. Secure power cords to the discharge pipe so they are out of the
way for proper float switch operation, prior to testing the unit.
Figure 3 - Secure Power Cords
11. Check the pump operation by filling sump with water and
observing pump operation through one complete cycle. For switch
settings see the Electrical and Switch Specifications chart in this
manual.
Risk of flooding. Can cause personal injury and/or
property damage. Failure to make this operational check may lead
to improper operation, premature failure, and flooding.

OPERATION
1. The shaft seal depends on water for lubrication. Do not operate
pump unless it is submerged in water as seal may be damaged if
allowed to run dry.
2. Motor is equipped with automatic reset thermal protector. If
temperature in motor should rise excessively, switch will cut off all
power before damage can be done to motor. When motor has cooled
sufficiently, switch will reset automatically and restart motor. If
protector trips repeatedly, pump should be removed and checked
as to cause of difficulty. Low voltage, long extension cords, clogged
impeller, very low head or lift, or a plugged or frozen discharge pipe,
etc., could cause cycling.
3. Pump will not remove all water. If operating a pump manually, and
suddenly no water comes out of the discharge hose, shut off the
unit immediately. The water level is probably very low and the unit

has broken prime.

Risk of electric shock. Can shock, burn or kill. Do not
handle a pump or pump motor with wet hands or when standing on
wet or damp surface, or in water.
Risk of electric shock. Can shock, burn or kill. Before
attempting to check why unit has stopped operating, disconnect
power from unit.
Lift is the vertical distance the pump actually lifts water. The higher
the lift, the lower the flow.
The friction caused by water running through the pipe will also,
on longer pipe runs, reduce the flow. Pipe smaller than the pump
discharge also reduces flow.
