1. Place battery box within six feet of
the sump and a 115 VAC separately
fused outlet. The outlet must be
protected by a ground fault circuit
interrupter (GFCI). The area must also
be clean, dry and well-ventilated.
2. Wave cardboard over batteries to
blow away any gas that may be
present.
3. Connect jumper wire between
batteries as shown on Figure 1.
4. Connect power wires from PS/BC to
battery terminals as shown in
Figure 1. Connect the red wire to
the unconnected positive terminal
of battery A and then connect the
black wire to the unconnected
negative terminal of battery B. The
yellow light should now be on.
5. Plug the pump and then the float
into the PS/BC. The connections are
marked.
6. Test pump operation by filling the
sump with water while the main
pump is unplugged. If the pump
operates properly, plug the PS/BC
into the GFCI protected outlet to
begin charging the battery.
NOTE: Protect electrical cord from sharp
objects, hot surfaces, oil and chemicals.
Avoid kinking the cord and replace
damaged components immediately.
Operation
Always disconnect the power
source before attempting to
install, service, relocate or
maintain the pump. Never touch sump
pump, pump motor, water or discharge
piping when pump is connected to
electrical power. Never handle a pump
or pump motor with wet hands or when
standing on wet or damp surface or in
water. Fatal electrical shock could occur.
Risk of electrical shock! Use a
GFCI receptacle to reduce the
risk of fatal electrical shock.
Cutting the cord or plug will void the
warranty and make the pump inoperable.
1. After installation, the backup pump
will start when the water level rises
above the depth that the primary
pump should start.
2. The PS/BC has a DC charger designed
to shorten the recharging time of
your battery, and to prevent
overcharging. In addition, the
control box has a time delay which
keeps the pump from repeated,
short cycles when it shuts off. This
time delay feature will allow the
pump to run 15 seconds after the
switch reaches the off position.
Maintenance
Unplug main AC pump and the
charger. Risk of electrical
shock!
Always disconnect the
electrical supply before
attempting to install, service,
relocate or per-form any maintenance. If
the power source is out of sight, lock and
tag in the open (off) position to prevent
unexpected power application. Failure to
do so could result in fatal electrical
shock. Only qualified electricians should
repair this unit. Improper repair could
result in fatal electrical shock.
Once a month,
check the condition
of the battery. In order to review the
battery condition, follow the steps that
are listed below:
BATTERIES
Dangerous
hydrogen gas can
be released from batteries while
charging. Sparks can ignite the gas in
an enclosed space. Wear safety goggles
when connecting batteries. Battery
connections should be made in a well-
ventilated area.
Working in the
vicinity of lead acid
batteries can be dangerous. Before making
connections or servicing the batteries, read
and follow instructions in all applicable
instruction manuals. To reduce the risk of
battery explosion, follow the instructions
in this manual and those published by the
battery manufacturer, as well as those of
any other equipment used in the
surrounding area.
If battery acid contacts your eye(s),
flush with cold running water for 10
minutes and seek immediate medical
attention. If acid contacts your skin or
clothing, wash immediately with soap
and water.
Never smoke or allow a spark or flame
in the vicinity of the battery.
Avoid dropping metal tools on the
battery posts because they may spark
or short-circuit the system or battery,
causing an explosion.
Follow battery manufacturer’s
maintenance procedures and
schedules. Be certain that the area
around the batteries is well ventilated.
Before servicing the batteries, blow
away gasses by waving a piece of
cardboard near the batteries.
1. Unplug the PS/BC.
2. For batteries with top caps that can
be removed, the electrolyte level
should be checked and filled to
manufacturer’s specifications. The
charge for each cell should be
checked with a hydrometer. A
specific gravity of 1.265 indicates
the battery is at full charge. If the
specific gravity of any of the cells
varies more than .050, the battery
should be replaced.
NOTE: An inexpensive hydrometer
can be purchased at an automotive
parts dealer.

Operating Instructions and Parts Manual
3. A check valve will be required in
the discharge line of BOTH the
Main AC pump and the ESP45
pump to prevent recirculation of
water into the sump pit. System will
not function without two check
valves.
4. Cut a 4’ section of 11/4" or 11/2"
diameter rigid PVC pipe. Cement
11/2" pipe to a threaded fitting.
Cement 11/4" pipe into pipe
coupling. Attach 11/4" pipe section
to the ESP45 discharge adapter.
5. Screw on to pump discharge.
Be careful not to
strip or cross thread
plastic fittings or check valves. Flex hose
is not recommended. Rigid PVC or metal
pipe is required for a permanent
installation.
6. Place the pump with the 4’ section
of PVC pipe on the sump floor or
on an elevated surface if required.
7. Attach a rubber check valve (sold
separately) to the top of the
discharge pipe. This will allow the
pump or check valve to be removed
easily for servicing.
8. Duplicate the discharge piping
arrangement for the primary AC
pump if the existing discharge line
has to be adjusted to accommodate
a second pump.
9. Glue a 45º elbow to the short pipe
on the ESP45 pump. Glue a “Y”
adapter to the short pipe on the
existing pump, as shown in
illustration for Method 2.
10. Glue a short piece of PVC pipe
between the 45º elbow and the “Y”.
NOTE: Check valves can be placed
directly in the pump discharge if
desired. However, for ease of
disassembly, it is recommended that
check valves be placed above the sump
as shown in Figure 3.
The remainder of the discharge pipe
installation will vary depending on
individual circumstances. Using sound
plumbing practices, route the
discharge pipe to an exterior wall by
the shortest distance.
Methods 1 and 2
Install float switch at least 10”-12”
above bottom of sump pit so that
backup unit turns on only when the
water level is higher than the normal
“on” level for main pump. Use the hose
clamps provided to secure the switch to
the discharge pipe. Make sure power
wires and hose clamp ends do not
interfere with float switch, pump inlet,
or main pump operation. Backup pump
must not be allowed to run dry.
PS/BC Installation
Use Power Supply/
Battery Charger
(PS/BC) indoors, in a well-ventilated
area. Do not expose PS/BC to rain or
snow. Do not use an extension cord. Do
not disassemble PS/BC. Be sure PS/BC
ventilation holes are unobstructed. If
PS/BC is dropped or damaged, do not
operate; return to manufacturer for
service.
Risk of electrical
shock! Use a GFCI
(Ground Fault Circuit Interrupter)
receptacle to reduce the risk of fatal
electrical shock. Grounded receptacle must
be rated for at least 5 amps.
Always disconnect
AC power and
remove pump fuse before connecting or
disconnecting battery.
1. Select a suitable position on the floor
near the sump pit to place the battery
case. Be certain that the PS/BC power
cord will reach AC power, and that
the sump pump power cord will reach
the PS/BC. Make sure the battery case
vent holes are unobstructed.
ELEVATE PS/BC BY MOUNTING ON
WALL OR SETTING ON A SHELF. SLOTS
IN THE BACK SIDE OF PS/BC ARE
AVAILABLE FOR WALL MOUNTING.
Control Box Installation
If cables are
reversed, damage
to the PS/BC or battery could result,
and warranty will be void.
Dangerous hydrogen gas can be
released from batteries while charging.
Sparks can ignite the gas in an
enclosed space. Wear safety goggles
when connecting batteries. Battery
connections should be made in a well-
ventilated area.
