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.
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.

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.
Control Box Installation
If cables are
reversed, damage
to the PS/BC or battery could result,
and warranty will be void.
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.
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.
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.

minutes and seek immediate medical
attention. If acid contacts your skin or
clothing, wash immediately with soap
and water.

Maintenance
Unplug main AC pump and the
charger. Risk of electrical
shock!
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.
Never smoke or allow a spark or flame
in the vicinity of the battery.
Always disconnect the
electrical supply before
attempting to install, service,
Avoid dropping metal tools on the
battery posts because they may spark
or short-circuit the system or battery,
causing an explosion.
NOTE: Protect electrical cord from sharp
objects, hot surfaces, oil and chemicals.
Avoid kinking the cord and replace
damaged components immediately.
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.
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.
Operation
Once a month,
check the condition
of the battery. In order to review the
battery condition, follow the steps that
are listed below:
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.
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.
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.
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.
NOTE: An inexpensive hydrometer
can be purchased at an automotive
parts dealer.
