2. Loosen the conical nut using an 1/8”
Allen wrench.
3. Carefully remove thrust washer and
thrust bearing, taking note of their
orientation. The thrust washer can
crack if it is dropped on a hard
surface.
4. Using needlenose pliers, remove
the impeller rotor. Take care not to
damage the mounting face of the
thrust washer with the pliers.
5. Thoroughly clean the filter with
soapy water. 
6. Remove any debris from impeller
vanes and passages. Wash impeller
in soapy water. Impeller magnet
will crack if it is dropped on a hard
surface.
7. Inspect thrust bearing. If its
thickness is less than 0.15” or if it is
cracked or damaged, replace.
8. Inspect the three impeller drives
that engage with the thrust
washer. Replace impeller if they are
worn.
9. Inspect thrust washer. Replace if
the thrust surface is worn. 
10. Reassemble parts in reverse order,
as shown in Figure 5. For proper
orientation of the thrust washer,
refer to Figure 6. Do not
overtighten the conical nut. Be
careful not to damage the float
when installing the filter cap.
2. Do not operate the pump unless it is
submerged in water. Dry running
causes pump failure.
3. While the pump is draining the pit,
verify that the discharge piping is
carrying the water to a point several
feet away from the foundation.
4. If pump discharge line is exposed to
freezing temperature, the exposed
line must be pitched to drain.
Trapped water will freeze and
damage the pump.
Maintenance
Always disconnect
the electrical
supply before attempting to install,
service, relocate or perform 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.
When necessary, 
remove the filter
for cleaning. If the pump is used in a
dirty environment, frequent cleaning is
necessary to assure adequate
performance. Never sweep dirt or
garbage into the sump pit. 
Do not operate 
the pump without
the filter in place. The filter protects
critical areas inside the pump from
damage due to foreign objects.
Operating the pump without the filter
will void the warranty.
Before disabling 
your pump, have
ready an appropriate way to evacuate
the sump pit should it refill with water
while your pump is out of commission.
Disconnect the power cord from the
Power Supply/Battery Charger (PS/BC)
to the pump. Simply unplugging the
PS/BC from the AC power will not shut
off the pump.
FILTER, IMPELLER AND THRUST
BEARING
1. Remove the pump from the sump
pit. Loosen the three (3) through
bolts that hold the filter cap in
place. 
Be careful not to 
damage the float
switch, which is permanently installed
in the motor housing. Attempting to
remove the float switch will cause
irreversible motor damage.

Operation
(Continued)
PROPER GROUNDING OF AC POWER
CORD
1. A ground fault circuit interrupter
(GFCI) is required (See Figure 4).
2. The PS/BC is only for use on 120 volt
(single-phase), 60 hz service and is
equipped with a 3-conductor cord and
3-prong, grounding type plug. The
plug MUST be plugged into a
ground fault circuit interrupter
outlet that is properly installed
and grounded in accordance
with all local codes and
ordinances. 
If you ever feel even a
sight shock from this or any electrical
appliance, or equipment connected
to it, STOP. Turn off electricity to
outlet, and have it inspected by an
electrician. You may have a
dangerous, improperly wired outlet.
IMPORTANT: Never cut off the round
grounding prong. Cutting the cord or
plug will void the warranty and make
the pump inoperable.
3. Insert the PS/BC power cord plug
directly into the GFCI outlet (See
Figure 4).
TO TEST
Make certain there
is at least 6 inches
of water in the sump prior to
connecting the pump to the PS/BC.
Failure to do so may cause damage to
pump.
1. Fill sump with water. The pump will
start automatically when the water
has filled the sump to a depth of
approximately 12“. The pump will
stop when the water depth is
approximately 6”. The pump will
recycle thereafter as required.

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.

DANGER
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.
Always
disconnect
the electrical supply before
attempting to install, service,
relocate or perform any
maintenance. 
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

DANGER
!
WARNING
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.
3. Inspect the terminals and clamps for
corrosion and tightness. Clean and
tighten as required.
4. Check for proper pump operation.
BATTERY TEST
1.  Unplug AC power.
2. Fill sump with water. Pump will start
automatically when water reaches
edge of filter cap.
3. If low battery light (yellow LED)
illuminates, batteries should be
replaced. Replace batteries as a set.
