Installation • Operation
6. Once the Combo Kit is firmly seated in the base of the
pit, connect the hose and clamp switch to the existing
discharge pipe and clamp it securely.
7. Secure power cord (PSP & BSP), piggyback switch,
and reed switch cord high up and around pipe with
a cable tie. Plug the primary pump into a standard
household 15 amp outlet.
NOTICE The circuit should be dedicated to the sump
pump exclusively.
Remember: Do not handle the pump while it is
plugged in; whether it is running or not.
8. Connect BBU. See "BBU Wiring and Setup".
9. Once all wiring is complete, fill your pit with water
and verify that the PSP removes the water and the
BBU doesn't run. Then, unplug your PSP and refill
your pit with water. Verify that the BBU removes the
water.
10. Make sure that the power is on to both pumps, and
your system is ready to use.

Operation

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.
1. 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, switch will cut off
all power before damage can be done to motor. When
motor has cooled, switch will reset automatically and
restart motor. If protector trips repeatedly, pump should be
removed and checked. 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 unit has
broken prime due to a very low water level.
Risk of electric shock. Can shock, burn or kill.
Before attempting to check why unit has stopped operating,
disconnect power from unit.
