Operation
CHARGER OPERATION
The backup pump will activate automatically when the
backup sump water level rises far enough to trip the float
switch.
If the power to the charger circuit is interrupted, the
length of time that the backup pump will run depends on
the Ampere-hour capacity of the battery used, the battery
charge level, and the required vertical pumping distance.
Extended periods of operation (for example, during an
extended power outage) may exhaust the battery. The
battery charger will begin charging the battery as long as
the battery has a voltage differential of 3Volts or more.
Recharge Time:
A5500: Approximately 19 hours to fully recharge a size
27M Marine Deep Cycle Battery in a "dead battery con-
dition". The approximate recharge time for a size 24M
Marine Deep Cycle Battery is 15 hours. Industrial stan-
dards define a "dead battery condition" as 9 Volts or less.
The 5 Stages of the Charging Process:
NOTICE: The LED's will only illuminate once the AC
power has been applied. They will not light up if the
charger is not plugged in.
1. Yellow "charging"(bicolor) LED flashing slowly
indicates:
A. Prequalification test stage is in progress. The nor-
mal duration of this stage is 20 seconds to 3 min-
utes. However, if a battery has been left in a state
of discharge for long periods this stage may require
2 hours to determine if the battery will even accept
a charge.
Yellow "charging" (bicolor) LED flashing slowly
and the "low battery alarm" Red LED also flashing
at the same rate as the yellow LED indicates:
B. A third prequalification test will be applied to the
battery if:
• it is a 6 Volt battery
• the battery has two or more bad cells
• the battery is in a heavily discharge state.
2. Yellow (bicolor)"charging" LED continuously on
indicates:
Constant current charge stage. Charger is charging

3. Yellow (bicolor)"charging" LED flashing quickly
indicates:
Constant voltage charge stage. Battery cells are being
equalized.
4. Green (bicolor) "charging" LED indicates:
Float charge stage. Battery terminal voltage is reduced
to a regulated voltage and battery is being maintained
at full charge.
5. Recycle charge stage:
The charger automatically initiates a charge cycle that
begins with the prequalification test stage. This occurs
once the battery has been in the float charge stage for
84 days.
Special Features:
• The chargers are equipped with reverse battery, short
circuit, and "run-away charge" protection.
• A built-in safety timer starts when the charger enters
the Constant Current/Constant Voltage Charge stage
(Yellow LED is continuously on). The A5500 system
has a 20.5 hour safety timer.
• To reset the charger simply unplug it from the 120V
outlet for 10 seconds and then plug it back in.
BATTERY REQUIREMENTS
Hazardous electrical current. Can cause
severe burns and start a fire if battery terminals are short cir-
cuited. Install the battery in a battery box (See Key No. 9,
Page 13). To prevent accidental shorting across battery ter-
minals, strap cover securely (See Figure 10) on the battery
box. Do not leave battery uncovered. Do not allow children
to play around the battery backup system installation.
