grounding. All electrical installations must conform to the National Electric Code and all local
codes.
• ELECTRICAL SHOCK ALERT.
Connect the AC adapter to a properly-grounded 115 volt circuit equipped with a Ground Fault
Circuit Interrupter (GFCI) device. Make sure the electrical supply circuit is equipped with fuses or
circuit breakers with a minimum capacity of 15 amps.
• ELECTRICAL SHOCK ALERT.
Never use an extension cord.
• ELECTRICAL SHOCK ALERT.
Do not remove or replace the power cord.
• ELECTRICAL SHOCK ALERT.
Protect electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid kinking the cord.
• ELECTRICAL SHOCK ALERT.

PREPARATION
Estimated Installation Time: 2-4 hours
Materials required for assembly: Deep-cycle marine battery, discharge piping and fittings (PVC,
poly pipe or galvanized steel), ‘Y’ pipe, 1-1/2-in 45° elbow, 1-1/2-in check valve, 1-1/4” MNPT x 1-1/2”
PVC socket adapter and 2-step PVC glue system (primer and sealer).
GENERAL PUMP INFORMATION
SPECIFICATIONS
MODEL PERFORMANCE IN GALLONS PER MINUTE
0 FT. 5 FT. 10 FT. 14 FT.
STBB100 29 20 10 Shut Off
This pump is designed to be installed in a sump basin along with a primary, 115V sump pump
for removing clear drain water. It is not a substitute for a primary sump pump. It is designed to
temporarily backup the primary sump pump in the event of a power outage or 115V pump failure.
The sump basin must be at least 18-in deep by 14-in diameter.
This system is designed to work with a deep-cycle marine battery, either a  ooded lead-acid battery
or a sealed, maintenance-free lead-acid battery. Use of an automobile battery instead of a deep-cycle
marine battery in this system will signi cantly reduce pump performance. Automobile batteries are not
designed for this type of application and will not stand up to repeated charge and discharge cycling.
Both the primary pump and DC backup pumps will require check valves in the discharge pipes for
proper operation.
NOTE: Pump must be submerged in water before operation. Running the pump dry will cause
damage and void the warranty.
NOTE: The alarm will sound after connecting the battery. It will continue to sound until all
connections are made and the  oat switch is in the down position.
The pump will continue to run for an additional 10 seconds after the float has been lowered. The
alarm will continue to sound while the pump is working.
Place the battery in a cool, dry, well-ventilated area on a shelf or protective plywood board. If a carbon
monoxide (CO detector) is installed in the same area as the DC pump system, it must be at least
15 ft. away from the battery in order to avoid nuisance CO alarms. Refer to CO detector installation
guidelines for more information.

INSTALLATION INSTRUCTIONS
NOTE: Install the battery backup system when the
primary pump is not needed. Read instructions and
prepare all supplies before beginning installation.
1. Verify that the existing 115V sump pump is in
good working order. It is best to use a primary
sump pump with a vertical  oat switch. Pumps
with tethered  oat switches require more space
and may interfere with the operation of the
backup sump pump switch.

2. Manually operate the primary sump pump to
remove as much water as possible from the
basin. Do not let the pump run dry.
3. Disconnect the primary sump pump from power
source before installing the DC pump.
WARNING: Never handle a pump with wet
hands or when standing on wet or damp
surface or in water. Fatal electrical shock
could occur.

10. Loosely attach the DC pump switch clamp to
the DC pump discharge pipe. Slide the switch
mounting bracket under the switch clamp.
Adjust the position of the switch so that the ‘ON’
level of the DC pump is above the ‘ON’ level of
the primary pump. Tighten the mounting clamp
of the DC pump switch in the correct location.
11. Place a fully-charged, deep-cycle marine battery
inside the battery box. Connect the leads inside
the battery box from the controller to the battery:
WARNING: Connecting the wires to the wrong
terminals on the battery may cause damage to the
controller.

NOTE: The alarm will sound after connecting
the battery. It will continue to sound until all
connections are made and the float switch is in the

NOTE: Be sure the battery box ventilation holes are
unobstructed. Battery control box must be set up in a
well-ventilated area, away from any smoke, flames or
pilot lights.

NOTE: Assemble pipe and fittings without glue to
check for proper fit.
9. Connect pumps, pipe, check valve and fittings
to verify the position in the sump pit. Once fitting
is correct, glue all joints using 2-step PVC glue
and primer.
Both the primary pump and DC backup pumps
will require check valves in the discharge pipes
for proper operation. BOTH check valves should
be located between pump discharge and where
the discharge pipes are joined.

13. Test DC pump operation by lifting up the DC
float switch and holding it in place. The pump
‘Pump Status’ LED will show a continuous light
and the alarm will beep steadily. The pump
should start at this time. If it doesn’t start, check
all connections.
NOTE: The pump will continue to run for an
additional 10 seconds after the float has been
lowered. The alarm will continue to sound while
the pump is working.
14. Test all system connections by pressing the
‘RESET’ button for 1 - 4 seconds. The alarm
will sound. This will cause the system to run
a self-test and the DC pump will run for 3
seconds.
To silence the alarm, press the ‘RESET’ button,
hold for 4 - 8 seconds and release. The alarm
should stop.
After the system returns to normal status, the
alarm will automatically reset. SW1401 A

NOTE: Sump basin must be filled with water before
operation. Running the pump dry will cause
damage and void the warranty.
1. Verify 115V pump operation by filling the basin
with enough water to raise the float on the
primary sump pump. Pump should start and
remove water.
Unplug the 115V from the power source.
2. Test DC pump operation by refilling the sump
basin with water until the DC pump float moves
to the top of the float rod.
The DC pump should start and pump water out
of the sump basin. If pump does not operate,
check all wire connections.
