Test the Assembly:
1. Plug the primary pump into a properly grounded 3-prong
outlet.
2.FLU the sump with water to start the primary
pump.
Check for leaks.
3. Unplug the primary pump and fig 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 58 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 llglht: C0nstant voltage charge
stage. Cells are being equalized.
4. Green
LED light: Roat 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 prequallflcation
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
LEDis 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.

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.
