SP24 Battery Backup Manual and Troubleshooting Guide.pdf 2 3/27/15 9:31 AM
Entire Sump System
The SP24 backup sump pump is designed as an
emergency backup system to support your main
AC sump pump, and it will automatically begin
pumping any time the float switch is activated by
rising water.
If your main AC pump breaks or is unable to keep
up with all the incoming water, the SP24 pump is
capable of running without discharging the battery,
as long as the AC power is on. As soon as the AC
power is interrupted, the battery takes over. Should
any malfunction or emergency occur that involves
the sump pump, the battery, or the AC power, the
SP24 system will sound an alarm. A light on the
display panel of the control unit will indicate the
cause of the alarm and the corrective action.
For added reliability, the float switch has, not one,
but two floats mounted within a protective cage.
Should one float fail to operate, the second float
automatically activates the pump. The protective
cage prevents debris or other wires from interfering
with the movement of the floats.
To extend the battery run time, two batteries may
be connected to the backup pump system by
purchasing a second battery and acid pack, as well
as a set of battery jumper cables. Jumper cables
specifically designed for this use are available from
Standard Water Control Systems.

The next section deals largely with battery
maintenance. Since April of 2016 we
have installed maintenance free batteries.
Which means adding uid is not necessary
and a lot of this section may not apply to
you. Still, this section is important for all
customers who have had Battery Backup
Sump Pump Systems installed. It details
how to access, connect, and/or disconnect
the battery and will be helpful to everyone
who owns a Battery Backup Sump Pump
System.

A new Pro Series 2200 Standby Battery will run
this system for a minimum of 8 hours continuously.
However, most of the time the pump will turn
on and off, and this battery will run the pump
intermittently for days.
To increase the running time of this system to 16
hours of continuous pumping, two batteries can
be connected together. Ideally the batteries should
be of similar age and capacity. Connecting an old
and new battery together will not charge properly.
Specific connection instructions will be explained
on pages 4 and 5.
In addition, the unique materials in the Pro Series
2200 Standby Batteries enable them to last for five
to seven years in standby service.
The Pro Series Standby batteries are shipped dry
(without acid) so they never lose power before
you take them home. A battery is activated when
the acid is added, and then it slowly begins to
deteriorate as it ages. By adding the acid just
A newly filled battery will sometimes require
additional acid after about 20 minutes. Re-examine
the fill level, and add additional acid if necessary.
The battery acid may bubble at this time and give
off a sulfur-like smell, but this is normal. After
the battery has been filled, screw the six (6) caps
securely on the top of the battery.
The battery will be charged 70-80% 30 minutes
after adding the acid. The system will then finish
charging the battery. During this time the alarm
may sound. The alarm will shut off within 24 hours.
This backup system will also accommodate a
maintenance-free battery, eliminating the need to
fill the battery. Slide the switch on the front of the
controller panel to the type of battery being used

battery has been filled, press the caps securely on
the top of the battery.
Position the control unit in a
secure place approximately
four (4) feet above the floor.
Be sure the power cord will
reach the AC power outlet, and
the pump cable and the float

and it will remain running as long as the water
is above the float. When the water drops below
the float switch, an internal timer in the control
unit will keep the pump running an additional
25 seconds to empty the sump pit. The switch
should be mounted about six (6) inches above the
water level line in the sump pit. (a) Attach the float
switch very securely to the discharge pipe with
the stainless steel hose clamp. (b) If the pump
is stacked above the main AC pump in a narrow
sump pit, the float may be attached to the elbow
of the pump. Unscrew the clamp. Wrap it around
the float bracket and pipe, and then tighten the
screw until the float is secure. Be sure the switch
is positioned vertically with the mounting bracket
at the top. Do not tilt the switch. Do not position
the float switch on the side of the discharge
pipe facing the drain tile or any incoming rush of
water!
2. Connecting the pump: Remove the security tag
from the pump and plug the pump wires into the
pump connector on the back of the control unit.
Keep the backup pump wire, the AC pump wire,
and the float wire separate from each other. Do
not let them cross on the final installation.
3. Installing the battery fluid sensor: Remove the
cover of the battery box by pushing in the tabs
on the front and back, then lifting up. Fan the
area around the top of the battery with a piece
of cardboard (or other non-metallic material) to
remove any hydrogen or oxygen gas that may
have been emitted from the battery. (a) Place the
fluid sensor in the hole provided on the top of the
battery. It is located in the second cell from the
positive post, and the location is marked by an
arrow on the top label. Hold the sensor straight
up and press it firmly in to the hole. Do not bend

If the battery alarm goes on while the pump is
running and the power is out, you will have a
minimum of one (1) hour of continuous pumping
time to replace the battery. (In most cases, the
pump does not run continuously, and therefore, you
actually have a longer time to replace it.) You will
not be able to silence the alarm. Left unattended,
the basement will flood. In a severe emergency, if
a replacement battery is not available, you could
This light and alarm will come on when the control
unit detects there is less than one (1) hour of
pumping power left in the battery, or that the battery
is defective. The alarm cannot be silenced, because
action needs to be taken to protect your basement.
If your battery is more than five (5) years old, replace
it. If not, here are several situations that would
cause the pump to run the battery for an extended
time and discharge the battery. Check the list below
before you replace the battery.

SP24 Battery Backup Manual and Troubleshooting Guide.pdf 9 3/27/15 9:32 AM
Lift
Float
Your SP24 backup sump pump system has a gauge
which will report the level of charge remaining in the
battery. As the battery’s energy is depleted during
operation without AC power, or simply by aging, the
gauge will indicate the percent of charge remaining
in the battery. Should the level drop below 25%,
the “Battery problem” indicator will light up and the
alarm will sound.
Lift the float up and let go. This will activate the
pump. The control unit will run the pump for
approximately 25 seconds so that it can empty
all the water in the sump pit. While the pump is
active, water will come out of the 1/8̯ hole that
was drilled into the PVC discharge pipe. This is
normal. The hole is needed to prevent an air lock
within the system. DO NOT obstruct the hole or an
air lock may prevent the system from activating. If
there is no water in the pit, the pump can run dry
for this amount of time. The alarm will sound and
the “Pump was activated” light will go on. After
the pump has stopped, push the GRAY button to
silence the alarm. If the GRAY button is pressed
before the pump has stopped, the alarm will go off
temporarily. Wait for the pump to stop pumping,
and then push the GRAY button on the front of the
control unit to completely silence the alarm. BE
SURE TO PLUG IN THE MAIN AC PUMP WHEN
YOU HAVE COMPLETED THE TEST.
The SP24 control unit can be connected to a home
security system or other alarm devices to alert you
to a problem or required maintenance.
The terminal is located on the back of the
control unit. There are three (3) positions for wire
connections on the terminal: N.C. .normally closed,
N.O. – normally open, and common.
Check your security system to determine whether
an open (no contact) or closed (making contact)
connection is needed to activate the alarm.
The security system will provide two connection
terminals. You will need to extend wires from the
security system to the SP24 control unit. Strip
the two wires, 1/4̯ each. Connect either wire to
the common terminal. To secure the wire into the
terminal, insert the exposed wire into the hole on
the back of the terminal next to the screw marked
common. Turn the screw a few turns to lock in the
wire.
You can receive technical support, parts,
or service information by calling
Standard Water Control Systems at
1-800-978-7867 or by visiting
www.StandardWater.com.
Maintenance should be performed 1-2 times per
year.
It is important to manually test the float switch
periodically.

1. Lift the float switch as described at left.
2. Remove all debris from the bottom of the pit.
3. Remove all debris from the water.
4. Remove all debris from the float switch.
5. Fill the pit with water. Make sure the pump
turns on at the intended level.
6. While the pump is running, make sure the
pump is evacuating water at a good pace and
water is coming out of the 1/8̯ air bleed hole.
7. Remove the fluid sensor and yellow cap from
the battery and rinse any residue buildup from
the bottom of the battery cap. Replace the cap
and fluid sensor.
8. Check battery fluid levels once every four to six
months.
Unplug the main AC pump when installing or
servicing the backup pump to avoid electric
shock. Failure to do so could cause serious
injury or death. Review the safety instructions
on page 1.
