GENERAL INFORMATtON
The Battery-Powered Back-up Sump Pump is not a substitute
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 op­
eration. Do not use it to pump flammable liquids or chemi­
cals.
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 sys­
tem battery as soon as possible.
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, alarin will sound. Silence alarm by pushing
ALARM TEST/RESET.button. In normal (switch actuated) op­
eration, 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 TEST/RESET button when
alarm is not soimding. Alarm will then sotmd as long as but­
ton is held down. Pushing ALARM TEST/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 in­
terrupted. 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.
Extended periods of operation (for example, during an ex­
tended power outage) may exhaust the battery. However,
once the load is removed, usually it will self-regenerate &r
enough to allow the charger to start. The battery charger wiU
begin charging the battery as long as the battery has a charge
of at least 1/2 volt, and power is available to the charger.
After power is restored, charger will automatically re-charge
battery fully in about six hours.
NOTICE: Some trouble conditions will cause the alarm to
sound. See chart below for causes and action:
