CHARGER OPERATION
Backup pump will start automatically when sump water
level rises far enough to trip float switch. After a delay of
about 4 seconds, alarm will sound. Silence alarm by
pushing ALARM RESET button. In normal (switch ac-
tuated) operation, alarm is locked out until about 4
seconds after float switch has dropped to OFF position;
cycle can then begin again.
Test alarm by pushing ALARM RESET button when alarm
is not sounding. Alarm will then sound as long as button is
held down. Pushing ALARM RESET button to test alarm
overrides lockout, so alarm can be tested at any time.
If alarm sounds, check operation of primary pump, which
may need service. If battery backup operation is due to a
power outage, alarm will sound, but no service is likely to
be required to primary pump.
Battery charger has capacity to run pump and charge
battery at the same time as long as power to the charger is
not interrupted. If power to charger circuit is interrupted,
the length of time that the backup pump will run depends
on the Ampere-hour capacity of the battery used.
NOTICE: Charger will not start to charge battery unless
battery voltage is above 4 volts. If battery voltage is below
4 volts, charger will not start. In many cases, a battery that
has been exhausted (for example, after an extended power
outage) will self-regenerate far enough to allow charger to
start. This process may take several hours.
After power is restored, charger will automatically re-
charge battery fully in about 6 hours.
If battery has not reached a satisfactory voltage after 24
hours of charging, alarm will sound. In this case alarm
cannot be reset. Possible causes are:
1. Extended operation during power outage.
2. Battery depleted to less than 4 volts, extending
charging cycle to more than 24 hours.
3. Defective battery.
4. An intermittent open circuit (such as a loose
connection to battery clamp) can also cause alarm
to sound.
After restoring power or replacing battery, alarm can be
reset.

GENERAL INFORMATION
The Battery-Powered Back-up Sump Pump is not a sub-
stitute for your primary sump pump. It is designed as a
backup pump to pinch-hit for your primary sump pump
during a power outage or other problem which prevents
normal operation. Do not use it to pump flammable
liquids or chemicals. If pumping salt water, flush the
pump with clear water after use.
Keep battery charger dry and protected from damage.
In an emergency (such as an extended power outage)
which depletes the system battery, your automobile
battery may be temporarily substituted. Be sure to replace
the system battery as soon as possible.
