Test the Assembly:
1. Plug the primary pump into a properly grounded 3-prong
outlet.
2. Fill the sump with water to start the primary pump.
Check for leaks.
3. Unplug the primary pump and fill the sump with water
to start the backup system pump. Check for leaks.
4. Plug the primary pump back into a properly grounded
3-prong outlet. The system is now ready for operation.
CHARGER OPERATION
The backup pump will activate automatically and an alarm
will sound 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, the required vertical pumping distance, and the size
of the sump.
Extended periods of operation (for example, during an ex-
tended power outage) may exhaust the battery. The battery
charger will begin charging the battery as long as the battery
has a voltage differential of 3 Volts or more.
Recharge Time:
It will take approximately 43 hours to fully recharge a 24M
battery in a “discharged battery condition”. The approxi-
mate recharge time for the 27M battery is 56 hours.
Industrial standards define a “discharged battery condition”
as 10.5 Volts or less.
The 5 Stages of the Charging Process:
NOTICE:
All LED’s will illuminate once the AC power has
been applied. They will not light up if the charger is not
plugged in. The RED LED will remain on continuously to in-
dicate power to the charger. See Figure 6.
1.
Flashing yellow LED light:
Battery prequalification test
stage. Normal duration of this stage is from 40 seconds to
3 hours.
2.
Continuous Yellow LED light:
Constant current charge
stage. Charger is charging battery at the full rated output.
3.
Continuous Yellow LED light:
Constant voltage charge
stage. Cells are being equalized.
4.
Green LED light:
Float charge stage. Battery terminal
voltage has been regulated and system is ready for use.
Charging has stopped.
5.
Recycle charge stage.
Charger will automatically initi-
ate a charge cycle that begins with the prequalification
test stage. This occurs once the battery has been in the
float charge stage for 28 days.
Special Features:
• The charger is equipped with reverse battery, short cir-
cuit, 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 system has a 70 hour safety
timer.
• To reset the charger simply unplug it from the 120V out-
let for 10 seconds and then plug it back in.
BATTERY REQUIREMENTS
Hazardous electrical current.
Can cause se-
vere burns and start a fire if battery terminals are short cir-
cuited. Install battery in a battery box (See Key No. 10, Page
9). To prevent accidental shorting across battery terminals,
strap cover securely (See Figure 7) on the battery box. Do
not leave 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 perfor-
mance of the pump. We recommend the use of a size 27M
Deep Cycle Marine Battery or a size 24M Deep Cycle Marine
Battery. They will perform as indicated in Table III, below,
and stand up well to long periods of little or no use.
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.
