RULES FOR SAFE INSTALLATION AND OPERATION

CHARGER OPERATION
Backup pump will start automatically when sump water
level rises far enough to trip float switch. After a delay of
about 4 seconds, alarm will sound. Silence alarm by
pushing ALARM TEST/RESET button. In normal (switch ac-
tuated) operation, alarm is locked out until about 4
seconds after float switch has dropped to OFF position;
cycle can then begin again.
Test alarm by pushing ALARM TEST/RESET button when
alarm is not sounding. Alarm will then sound as long as
button is held down. Pushing ALARM TEST/RESET button
to test alarm overrides lockout, so alarm can be tested at
any time.
If alarm sounds, check operation of primary pump, which
may need service. If battery backup operation is due to a
power outage, alarm will sound, but no service is likely to
be required to primary pump.
Battery charger has capacity to run pump and charge
battery at the same time as long as power to the charger is
not interrupted. If power to charger circuit is interrupted,
the length of time that the backup pump will run depends
on the Ampere-hour capacity of the battery used.
Extended periods of operation (for example, during an ex-
tended power outage) may exhaust the battery. However,
once the load is removed, usually it will self-regenerate far
enough to allow the charger to start. The battery charger
will begin charging the battery as long as the battery has a
charge of at least 1/2 volt.
After power is restored, charger will automatically re-
charge battery fully in about six hours.
NOTICE: If battery has not reached a satisfactory voltage
after 24 hours of charging, alarm will sound. In this case
alarm cannot be reset. Possible causes are:
PROBLEM ACTION
Back-up pump has run Push ’Reset’. Check main pump.
Power out more than Disconnect charger from battery.
24 hours Call power company.
Continuous charging Disconnect charger from battery.
more than 24 hours Check for defective battery.
Loose connection or Disconnect charger from battery.
no power to charger Check plug, receptacle, and
power at main breaker.
After restoring power or replacing battery, alarm can be
reset.

GENERAL INFORMATION
The Battery-Powered Back-up Sump Pump is not a sub-
stitute for your primary sump pump. It is designed as a
backup pump to pinch-hit for your primary sump pump
during a power outage or other problem which prevents
normal operation. Do not use it to pump flammable
liquids or chemicals. If pumping salt water, flush the
pump with clear water after use.
Keep battery charger dry and protected from damage.
In an emergency (such as an extended power outage)
which depletes the system battery, your automobile
battery may be temporarily substituted. Be sure to replace
the system battery as soon as possible.

BATTERY REQUIREMENTS
Hazardous electrical current. Can cause
severe burns and start a fire if battery terminals are short
circuited. Install battery in box. To prevent accidental
shorting across battery terminals, strap cover securely on
battery box. Do not leave battery uncovered. Do not
allow children to play around sump pump installation.
Your Backup Sump Pump depends on the battery used
with it for power. The better the battery, the better the
performance of the pump. We recommend use of a SEARS
DieHard Size 27M or 24M Deep-Cycle Marine battery.
This battery will perform well for many hours and stands
up well to long periods of little or no use.
In an emergency a SEARS DieHard Size 27M or 24M stan-
dard automobile battery may be used. However, an auto-
motive battery may require charging after only 1 to 2
hours of continuous use, and the repeated charging cycles
may cause early plate failure in the battery.
Use only a new, fully charged battery that will fit in the
battery box (maximum size 12-5/8" long, 7" wide and 9-
3/8" high (320.7mm x 177.8mm x 238mm) including
terminals).
PUMP INSTALLATION and OPERATION
NOTICE: We recommend a trial fitting of all components
before gluing anything. This will allow you to check pump
mounting height, float switch clearance, etc., while
adjustments can still be easily made.
1.Mark side of sump six inches (154mm) down from top.
2.Fill sump until primary sump pump starts; normal high
water level should not be above mark made in step 1.
If it is higher, backup float switch may not swing far
enough for proper operation. To lower high water
level, adjust switch on primary sump pump. See
primary pump owner’s manual.
3.Drain sump. Measure down 11 inches (279.4mm)
from top of sump; mark this point on side of sump.
Install tee with center of threaded inlet at least this far
below top of sump to allow sufficient room for float
switch to swing (see Figure 1A).
4.Make sure that installation will not interfere with
primary sump pump operation as follows:
A. Backup pump installation must not interfere with
primary sump pump float switch swing.
B. Normal high water level must never be high
enough to start backup sump pump.
C. Install a check valve (SEARS Stock No. 2789) in the
main sump pump discharge pipe between the
pump and the backup mounting tee (see Figure 1).
Flow through this check valve must be away from
the main sump pump; don’t install it backwards!
This check valve will prevent recirculation into the
sump during battery-powered pump operation.
5.Cut rigid discharge pipe from primary sump pump to
length. Use PVC piping. Tee supplied is 1-1/2" slip fit;
if necessary use 1-1/4" bushings supplied.
NOTICE: Use any tee that fits sump pump discharge
line; the adapter that is supplied will fit any galvanized
or plastic 1-1/4" tee. Do not glue the tee until all parts
have been trial fitted.
6.Thread adapter into tee (Figure 1B). When installed,
molded-in ‘up’ should be on top.
7.Install backup pump check valve in adapter. Tab on
backup pump check valve fits into notch at top of
adapter.
8.For trial assembly, slip pump into backup pump check
valve to check pump mounting height and to make
sure that there is no interference with float switch
operation on either pump; be sure floats will not rub
on side of sump, catch between pump and sump wall,
interfere with each other, etc.
9.Remove pump from adapter; remove tee.
10.Using PVC glue, permanently reinstall tee in primary
sump pump discharge pipe.

ventilated place away from fire or flame.
11.Put clamp on adapter; leave loose. Mount backup
pump check valve in adapter; thread assembly into
tee.
12.Slip pump into check valve. Tighten clamp.
13.Make sure battery is fully charged; then check opera-
tion by disconnecting power to primary sump pump
and filling sump until Backup Sump Pump starts. Run
Backup Pump through one complete cycle.
ELECTRICAL CONNECTIONS
Hazardous voltage. Can cause serious or
fatal electrical shock. Review safety instructions, Page 2,
before operating charger.
If your outlet is not grounded, install a copper wire (at
least 14 gauge) from the outlet box to a cold water pipe.
Use ground clamp on pipe. BE SURE that the cold water
pipe used has metal continuity to electrical ground. Do
not modify cord or plug; do not use an extension cord.
CHARGER/BATTERY INSTALLATION
NOTICE: Alarm will sound when charger is first
connected to battery. Press ALARM TEST/RESET button on
charger. If alarm continues to sound, disconnect one
charger lead from the battery and reconnect it. Press
ALARM TEST/RESET again; alarm will stop sounding.
1. Connect charger as shown in Figure 2.
A. Connect Positive (+) lead from charger to positive
battery post.
B. Connect Negative (–) lead from charger to negative
battery post.
C. Third lead from charger is factory connected to
lead from pump motor/float switch.
NOTICE: If charger is connected backwards, pump
will not operate properly, battery will not charge.
2. Plug in power cord to a 115-125 Volt AC outlet deliv-
ering at least 2 amps. Do not use a switch controlled
outlet. Mark circuit in main power panel “Backup
sump pump power supply; do not turn off”.
3. With charger properly connected and plugged in, the
panel on the front of the charger will appear as in one
of the following:
A. If battery is dead, charger will supply about 10
amps power (see Figure 3A).
B. If battery is near full charge, charger will deliver
about 5 amps power (see Figure 3B).
C. If battery is fully charged, charging current will be
0 amps and green LED lamp will be lighted (see
Figure 3C).
4. The charger is equipped with a self-resetting circuit

breaker which protects it from temporary overloads. In
case of an overload, the circuit breaker will open. It
automatically resets after a short cool-down period. In
some conditions where the overload is extended the
breaker will cycle , repeating the open/reset process
indefinitely. When this happens, normally the charger
will emit a clicking sound as the breaker opens and
resets.
NOTICE: If the clicking sound continues for more than
30 minutes or so, check for reversed charger con-
nections to the battery and for shorted cells in the
battery.
BATTERY MAINTENANCE
NOTICE: To protect battery case from chipping and
gouging, do not let battery sit on concrete floor. Install
battery on a shelf or protective pad (plywood, 2x4s, etc.).
Always install battery in a dry location that is protected
from flooding.
Every three months, check battery as follows to maintain
battery in best condition:
1. Unplug battery charger.
2. On batteries with removable top caps, measure
specific gravity of the electrolyte. Use a hydrometer
(available at auto parts stores). If the specific gravity of
any cell is less than 1.225 or if there is more than .050
variation between cells, replace the battery.
3. Check electrolyte level and refill as needed.
4. Check battery terminals and clamps for tightness and
corrosion. Clean and tighten as needed.
5. Plug in battery charger.
TROUBLESHOOTING
Pump won’t run.
1. Check all connections.
2. Check for low or defective battery.
3. Check that automatic switch is free to swing up and
down.
4. Blown fuse in switch circuit. Unplug pump and check
to see if impeller is free to turn. If impeller is locked,
remove the housing around the impeller and remove
the obstruction. Reassemble pump and reconnect.
Replace fuse.
Motor hums but pump won’t run:
1. Check for low or defective battery.
Pump runs but pumps very little or no water:
1. Make sure a check valve is installed and functioning
between primary pump discharge and Backup Sump
Pump tee.
2. Check for obstruction in discharge pipe.
3. Discharge pipe length and/or height exceeds capacity
of pump. See Table I, Page 3, for pump capacity.
4. Check for low or defective battery.
Pump cycles too frequently:
1. Tether length too short on automatic float switch. Make
sure that tether is at least 2" (51mm); see Figure 1.
2. Main check valve located between discharge of primary
pump and the Backup Sump Pump tee or check valve
not installed or working properly. Install or repair as
required.

SWITCH REPLACEMENT
1. Unplug battery charger from wall outlet.
2. Disconnect both battery clamps from battery
terminals.
3. Unbolt black switch wire from battery clamp.
4. Unplug fuse holder in white wire; save fuse.
5. Make a note of tether length (see Figure 1) before
loosening cord clamp.
6. Remove cord from cord clamp and replace with new
cord. Make sure tether length is the same as the old
switch’s tether.
7. Strip insulation off of white wire on new switch,
leaving 3/8" (9.5mm) bare wire exposed at the wire
end (see Figure 4).
8. Insert stripped wire end in small end of fuse holder
half; crimp holder onto wire and check crimp for
tightness (Figure 5).
NOTICE: Be sure that fuse holder half which you are
installing will mate with fuse holder half on pump
wire.
9. Insert fuse into holder and snap halves of housing
together (Figure 6).
10.Remount block on band and cord clamp assembly on
pump.
11.Strip black switch wire back 3/8" (9.5mm) from end of
