that the standby system was used to empty the
water from the sump. Try to determine what
caused the system to activate.
• Check the main pump for failure. It may not
be working, the float switch may be stuck, or
the pump may be too small to handle the
inflow of water.
• Make sure the check valves are working and
installed correctly. They may need to be
replaced. (See page 12 for check valve
locations).
• Make sure the discharge pipe is not clogged or
frozen.
• If the power was out, and the backup pump
was activated, you need to push the RED
button to silence the alarm.
During a power
outage or times
when the pump is
activated
repeatedly, you can
temporarily silence
the alarm by sliding
the Audible Alarm
switch to OFF. When the primary pump has
resumed normal operation and the backup
pump is no longer activating repeatedly, slide
the switch to the ON position to resume the
full monitoring capability. The alarm and
pump light will still be on. Push the RED button
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 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 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.
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.
9. Turn the assembly up side down over the
sump pit to allow the remaining water in the
system to drain.
10. Loosen the screws on the no-hub connector
on the elbow of the backup pump.
11. 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.
12. Unscrew the check valve on the elbow of the
backup pump. Now reverse the process.
13. Screw the check valve on to the new pump.
(You can use the existing check valve, or
preferably replace it with a new one.)
14. 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.
15. Push the pump and check valve back up into
the no-hub connector, and place the pump
on the pump bracket.
16. Screw the pump onto the bracket.

17. Tighten the hose clamp on the no-hub
connector.
18. Lower the pump system back into the sump pit.
19. Connect the top of the system to the rubber
union and tighten the hose clamp.
20. Connect the battery cables to the battery
terminals, WHITE to the NEGATIVE (-) post,
and BLACK to the POSITIVE (+) post.
21. Insert the fluid sensor into the top of the
battery and replace the cover of the battery
box.
22. Plug the backup pump into the back of the
backup controller.
23. Plug the charger into the back of the backup
controller.
24. Plug the primary pump into the blue
controller.
