from repeated, short cycles when it shuts
off. This time delay feature will allow the
pump to run 20-25 seconds after the
switch reaches the off position.

Operation (continued)
4. The control box contains a multicolored
indicator light. When AC power is
present, the light will indicate the
charging state, and not reflect actual
battery voltage, particularly with a
defective battery. In order for the
indicator light to provide an accurate
reading, steps “a” through “d” must be
followed. a. Unplug primary AC pump and
the charger--a power off alert tone will
sound for 30 seconds.
b. Lift and release the float switch to
activate the back-up pump.
c. When the back-up pump stops, read
the test light:
Green: Indicates battery is
charged.
Yellow: Voltage is low,
indicating battery is partially
charged.
Red: Battery is completely
discharged or defective.
d. Plug in charger and main AC pump.
When AC power is out, and when pump
has been running, the light will indicate
battery status.
5. A chirping sound from the control box
will accompany the red light, indicating
that the battery may require attention or
replacement. Voltage is only an indicator
of battery condition and may not reflect
the true condition of the battery. See
Maintenance for instructions on
assessing battery condition.
6. A single 30-second tone will sound when
power to the system is interrupted. The
unit will reset automatically when power
is restored. A 3-second tone will sound
every time the pump starts.
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.
1. Once a month, check battery condition.
2. Unplug the wall charger.
3. 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.
4. Inspect the terminals and clamps for
corrosion and tightness. Clean and
tighten as required.
5. Unplug the main pump and fill sump
with water until back-up pump turns on.
Repeat process two times to be sure
pump is operating normally.
6. If pump operates normally, plug charger
into wall outlet, turn on main pump. If
pump fails to operate normally, see
Troubleshooting chart and correct
problem. Repeat step 5. 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.

Symptom(s)
Possible Cause(s)
Corrective Action(s)
Pump will not run
1. Connections not secure
2. Low battery
3. Float switch obstruction
4. Defective or blown fuse
1. Check all connections
2. Check battery and replace if low
3. Make sure nothing is interfering with the operation of the switch
4. Check internal fuse located inside the control box. Pull the charger from the wall outlet
and remove. If the fuse is blown, replace it with a 15 amp automotive type fuse
Motor hums but
pump won’t run
1. Defective battery
2. Obstructed impeller
1. Check battery and replace if low or defective
2. Unplug pump and check to see if impeller is free to turn. If impeller is locked, remove the 4
screws on the bottom of the pump to release the housing around the impeller. Remove
the obstruction. Reassemble pump and reconnect
Pump runs but
pumps very little or
no water
1. Check valve missing or improperly
installed
2. Obstruction in discharge pipe
3. Pump not rotated 30˚
4. Pump air locked
5. Discharge pipe length and / or height
exceeds capacity of pump
6. Low or defective battery
1. Check to make sure a check valve is installed and functioning between primary pump
discharge and standby sump pump tee fitting
2. Check for obstruction and clear if necessary
3. Check that pump is rotated 30˚ in tee fitting in ESP15 Installation section, Figure 3, on page
2
4. The impeller housing has a small hole on its side. This hole must be open for the pump to
prime. With the pump unplugged, remove the 4 screws on the bottom of the pump to
release the housing around the impeller. Clean out the hole and replace cover
5. If discharge is too high, a separate line may be required with a lower discharge height
6. Check battery and replace if low or defective
Pump cycles too
frequently
1. Main check valve located between the 1. Install check valve or repair as required
discharge of the primary pump and the back-up sump pump tee fitting or the back-up
sump pump flapper valve not installed or working properly
