Pre-Qualification Test – 1 and 2
Charger is charging at a very low level to try to bring a
dead battery back to life. If the battery is taking too long,
try resetting the charger once or twice (push the 'System
Test' and 'Silence Alarm' buttons to reset the charger).
Special Features
The charger is equipped with reverse battery, short
circuit, and "run-away charge" protection.
Battery Requirements
Risk of electric shock. Can shock, burn or
kill. Can start a fire if the battery terminals are short
circuited. Install the battery in the battery case as
described previously. To prevent accidental shorting
across battery terminals, close and latch the battery
case securely. Do not leave the battery uncovered. Do
not allow children to play around the battery backup
system installation.
Your backup sump pump depends on the battery used
with it for power. The better the battery, the better the
performance of the pump. We recommend the use of a
size 27M Marine Deep Cycle Battery. It will perform as
indicated in Specifications and will stand up well to long
periods of little or no use.
This system is designed to work with a deep cycle
marine battery, either a flooded lead-acid battery or a
sealed maintenance free lead-acid AGM battery. Use
of a standard automobile battery with this charger is
not recommended. An automobile battery may require
charging after only 1 –2 hours of continuous use, and the
repeated charging cycles may cause early plate failure in
the battery.
Use only the recommended battery or one of the same
type and size so it will fit in the battery box (maximum
size 13" long, 7" wide and 10" high [330.2mm x
177.8mm x 254mm] including terminals) and supply
enough voltage for full performance.
Battery Maintenance
Risk of burns. Battery posts, terminals
and related accessories contain lead and lead
compounds, chemicals known to the State of California
to cause cancer and reproductive harm. Wash hands
after handling.
NOTICE To protect the battery case from chipping and
gouging, do not let the battery sit on a concrete floor.
Install the battery on a shelf or protective pad (plywood,
2x4s, etc.). Always install the battery in a dry location
that is protected from flooding.
Follow the battery manufacturer's recommendations for
maintenance and safe use of the battery.
Troubleshooting
Pump won't run.
1. Check all the wiring connections.
2. Check for a low or defective battery.
3. Check that the automatic switch is free to move up
and down.
4. Press the circuit breaker reset button on the
control panel.
Motor hums but pump won't run:
Check for low or defective battery.
Pump runs but pumps very little or no water:
1. Make sure a check valve is installed and functioning
between the primary pump discharge and the Battery
Backup tee.
2. Check for an obstruction in the discharge pipe.
3. The discharge pipe length and/or height exceeds
the capacity of the pump. See Specifications for
pump capacity.
4. Check for a low or defective battery.
5. The Positive (+) and negative (–) pump wires are
reversed. Disconnect them and reconnect correctly.
Pump cycles too frequently:
The check valve located between the discharge of
the primary pump and the Battery Backup tee is
not installed or is not working properly. Install the
auxiliary check valve (see Installation) or replace the
existing check valve as required.
