post, and the RED wire to the POSITIVE (+)

Pump
When the water rises in the sump pit and
activates the float switch, the pump will begin
pumping, and the “Pump was activated” light
and alarm will turn on. Try to determine what
caused the system to activate.
• Check the main AC pump for failure. It may
not be working, the float switch may be stuck,
or it may be too small to handle the inflow of
water.
• Make sure the check valve is working
• Make sure the discharge pipe is not clogged or
frozen
• If the power was out, the backup pump was
automatically activated and protected your
basement. You need to push the YELLOW
button on the front of the control panel to
silence the alarm.
REPLACING THE BACKUP PUMP
Before you begin
this process you
will need a new
backup pump. You
may also want to
change the check
valves at this time.
The backup pump
uses a 1-1/4” check
valve, the primary pump uses a 1-1/2” check
valve. (See parts list on page 13.)
Risk of electrical shock or battery explosion,
which can cause serious injury or death.
Wear eye protection. Work in a well-
ventilated area. Do not smoke or allow a
spark or flame in the vicinity of the battery.
Avoid dropping metal tools on the battery.
Review the safety instructions on page 1.
REFER TO THE PHOTOS AT RIGHT
1. Unplug the primary pump from the blue
controller.
2. Remove the charger plug from the back of the
black controller.
3. Unplug the backup pump from the back of the
black controller.
4. Remove the sensor from the battery.
5. Remove the battery wires from the battery
terminals.
Be sure they do not touch each
other while one is connected to the battery.
6. Slowly loosen the rubber union on the top of
the combination pump assembly to separate
the pipes. The water trapped in the pipe will
pour out into the sump as the rubber union is
loosened.
7. Separate the pump assembly from the rubber
union and lift it out of the sump by the
handle on the primary pump.
8. Turn the assembly up side down over the
sump pit to allow the remaining water in the
system to drain.
9. Loosen the screws on the no-hub connector
on the elbow of the backup pump.
10. Unscrew the screw on the bottom of the
pump bracket with a Phillips head
screwdriver, and lift the pump off of the
bracket. Then pull the pump down out of
the no-hub connector.
11. Unscrew the check valve on the elbow of the
backup pump. Now reverse the process.
12. Screw the check valve on to the new pump.
(You can use the existing check valve, or
preferably replace it with a new one.)
13.
You must drill a 1/8” hole in the elbow of
the new pump to prevent an air lock in the
system. An air lock will prevent the pump
from operating. Drill the hole on a
downward slope below the check valve on
the elbow.
14. Push the pump and check valve back up into
the no-hub connector, and place the pump
on the pump bracket.
15. Screw the pump onto the bracket.
16. Tighten the hose clamp on the no-hub
connector.
17. Lower the pump system back into the sump
pit.
18. Connect the top of the system to the rubber
union and tighten the hose clamp.
19. Connect the battery cables to the battery
terminals, BLACK to the NEGATIVE (-) post,
and RED to the POSITIVE (+) post.
20. Insert the fluid sensor into the top of the
battery.
21. Plug the backup pump into the back of the
black controller.
22. Plug the charger into the back of the black
controller.
23. Plug the primary pump into the blue
controller.
