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 WHITE
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 WHITE
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.)
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
yellow controller.
3. Unplug the backup pump from the back of the
yellow 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, WHITE to the NEGATIVE (-) post,
and BLACK 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
yellow controller.
22. Plug the charger into the back of the yellow
controller.
23. Plug the primary pump into the blue
controller.
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.)
