GENERAL INFORMATION
The Battery-Powered Back-up Sump Pump is not a substitute
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 op-
eration. Do not use it to pump flammable liquids or chemi-
cals.
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 sys-
tem battery as soon as possible.
CHARGER OPERATION
Backup pump vdll 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 actuated) op-
eration, alarm is locked-out until about 4 sec6nds 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 but-
ton 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 in-
terrupted. 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, and power is available to the charger.
After power is restored, charger will automatically re<barge
battery fully in about six hours.
NOTICE: Some trouble conditions will cause the alarm to
sound. See chart below for causes and action:
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.

BATTERY REQUIREMENTS
[A WARNING] Hazardous electrical current. Can cause se-
vere burns and start a fire if battery terminals are short cir-
cuited. 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 perfor-
mance 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 standard
automobile battery may be used. However, an automotive
battery may require charging after only 1to 2 hours of con-
tinuous 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 bat-
tery box (maximum size 12-5/8" long, 7" wide and 9-3/8"
high including terminals).
PUMP INSTALLATION
and OPERATION
NOTICE: We recommend atrial fitting of all components
before gluing anything. This will allow you to check pump
mounting height, float switch clearance, etc., while adjust-
ments can still be easily made.
1. Mark side of sump six inches down from top.
2.Fill scamp 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 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 2A).
4.Make sure that installation will not interfere with primary
sump pump operation as follows:
A. Backup pump installation must not interfere with pri-
mary 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 Figures 2A and 2B).
How 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 (Key No. 10, Page 7) 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 2B). 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.
lO.Using PVC glue, permanently reinstall tee in primary
sump pump discharge pipe.

by disconnecting power to primary sump pump and fill-
ing sump until Backup Sump Pump starts. Run Backup
Pump through one complete cycle.
ELECTRICAL CONNECTIONS
AWARNING JHazardous voltage. Can cause serious or
fatal electrical shock. Review safety instructions, Page 2, be-
fore 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. Battery
charger is double insulated. DO NOT modify cord or plug.
CHARGER/BATI'ERY 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 3.
A. Connect Positive (+) lead from charger to positive battery
post.
B. Connect Negative (-) lead from charger to negative bat-
tery post.
C. Third lead from charger is factory connected to lead from
pump motor/float gwitch.
NOTICE: If charger is connected backwards, pump will
not operate properly, battery will not charge.
2. Plug in power cord to a115-125 Volt AC outlet delivering
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 iplugged in, the
panel on the front of the charger will appear _ in one of
the following:
A. If battery is dead, charger will supply about 10 amps
power (see Figure 4A).
B. If battery is near full charge, charger will deliver about
5 amps power (see Figure 4B).
C. If battery is fully charged, charging current will be 0
amps and green LED lamp will be lighted (see Figure
4C).

C. Charge comlSlete - current 0amps, LED lightsup.

4. The charger is equipped with aiself-resetting circuit
breaker which protects it from teanporary overloads. In
case of an overload, the circuit breaker will open. It au-
tomatically resets after a short cool<lown 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 dick-
ing sound as the breaker opens and resets.
NOTICE: If the clicking sound continues for more than
30 minutes or so, check for reversed charger connections
to the battery and for shorted cells in the battery.
BATTERY MAINTENANCE
NOTICE: To protect battery case from chipping and goug-
ing, do not let battery sit on concrete floor. Install battery on
a shelf or protective pad (plywood, 2x4s, etc.). Always in-
stall 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 hyclrometer (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 cor-
rosion. Clean and tighten as needed.
5. Plug in battery charger.
TROUBLESHOOTING

I. 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 Figure 5
see ifimpeller is free to turn. Ifimpeller is locked, remove
the housing around the impeller and remove the ob-
struction. 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 tittle or no water:
1. Make sure a check valve is installed and functioning be-
tween primary pump discharge and Backup Sump Pump
tee. Figure 6
2. Check for obstruction in discharge pipe.
3. Discharge pipe length and/or height exceeds capacity of
pump. See Table I, Page 4, for pump capacity.
4. Check for low or defective battery. Figure 7
