REPLACING THE PRIMARY PUMP
Before you begin this process you will need a
new AC 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 12.)
! DANGER
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 of 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
YOU WILL BE DISCONNECTING ALL THE
WIRES. BE SURE THEY DO NOT FALL INTO THE
SUMP PIT. SEE DIAGRAM ON PAGE 12 FOR
PARTS DESCRIPTION.
1. Unplug the primary pump from the blue
controller.
2. Remove the charger plug from the back of the
backup controller.
3. Unplug the backup pump from the back of the
backup controller.
4. Remove the cover of the battery box by
pushing in the tabs on the front and back,
then lifting up. Fan the area around the top
of the battery with a piece of cardboard (or
another non-metallic material) to remove any
hydrogen or oxygen gas that may have been
emitted from the battery.
5. Remove the sensor from the battery.
6. Remove the battery wires from the battery
terminals. Be sure they do not touch each
other while one is connected to the battery.
7. 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.
8. Separate the pump assembly from the rubber
union and lift it out of the sump by the
handle on the primary pump.

switch and remove the float switch.
11. Cut the cable ties on the backup float switch
and remove it.
12. Loosen the hose clamp on the top of the no-
hub connector on the primary pump.
13. Loosen the hose clamp on the top of the no-
hub connector on the backup pump.

out of the handle of the primary pump. Now
reverse the process.
17. Carefully slide the backup pump and bracket
into the handle of the new primary pump.
18. Screw in the check valve on the top of the
primary pump. (You can use the existing
check valve, or preferably replace it with a
new one.)
19. Connect the Y-connector to the top of the
check valve with the no-hub connector and
tighten the hose clamp.
20. Connect the backup pump to the other side
of the Y-connector with the other no-hub
connector.
21. Replace the caged float switch by tightening
it with its hose clamp.
22. Replace the backup pump float switch using 2
new cable ties. Make sure the float moves
easily, and will not get hung up on the pump.
23. Lower the pump back into the pit by the
handle of the primary pump.
24. Connect the top of the system to the rubber
union and tighten the hose clamp.
25. Connect the battery cables to the battery
terminals, WHITE to the NEGATIVE (-) post,
and BLACK to the POSITIVE (+) post.
26. Insert the fluid sensor into the top of the
battery and replace the cover of the battery
box.
27. Plug the backup pump into the back of the
backup controller.
28. Plug the charger into the back of the backup
controller.
29. Plug the primary pump into the blue
