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 or a size 24M
Marine Deep Cycle Battery. They will perform as indicat-
ed in Table III, on Page 9, and they stand up well to long
periods of little or no use.
NOTICE: A 24M battery will provide the same perfor-
mance as a 27M battery, but for a shorter length of time.
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 12-5/8" long, 7" wide and 9-3/8" high [320.7mm x
177.8mm x 238mm] including terminals) and supply
enough voltage for full performance.
BATTERY MAINTENANCE
Severe burn hazard. A filled battery contains
sulfuric acid. Avoid contact with skin, eyes or clothing.
NOTICE: To protect battery case from chipping and
gouging, do not let battery sit on concrete floor. Install
battery on a shelf or protective pad (plywood, 2x4s, etc.).
Always install battery in a dry location that is protected
from flooding.
Follow the battery manufacturer’s recommendations for
maintenance and safe use of battery.
TROUBLESHOOTING
Pump won’t run.
1. Check all wiring connections.
2. Check for low or defective battery.
3. Check that automatic switch is free to swing up and
down.
4. Check for a blown fuse in the charger of the A5500
system.
Motor hums but pump won’t run:
1. 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 primary pump discharge and Backup Sump
Pump tee.
2. Check for obstruction in discharge pipe.
3. Discharge pipe length and/or height exceeds capaci-
ty of pump. See Table III, Page 9, for pump capacity.
4. Check for low or defective battery.
5. Positive (+) and negative (–) wires are reversed.
Pump cycles too frequently:
1. Tether length too short on automatic float switch.
Make sure that tether is at least 2-1/2" (63mm); see
Figure 6, Page 6.
2. Main check valve located between discharge of pri-
mary pump and the Backup Sump Pump tee is not
installed or is not working properly. Install or repair
as required.
