BATTERY PROBLEM
This light and alarm will go on when the control
unit senses that the battery has approximately 1
hour of continuous pumping energy left. This
could occur when:
• Corrosion on battery terminals and/or cable
rings is preventing the battery from charging
properly
• The battery is getting old and should be
replaced
• The pump has been running for many hours
and the battery is below the 25% charge level
on the “Battery power level” gauge
Check the battery cables and the battery
terminals for corrosion. Clean and tighten them
as needed. The procedure is described in the
next column.
If the battery alarm goes on while the pump is
running and the power is out, you will have a
minimum of 1 hour of pumping time to replace
the battery. (In most cases, the pump does not
run continuously, and therefore, you actually
have a longer time to replace it.) You will not
be able to silence the alarm. Left unattended,
the basement will flood. In a severe emergency,
if a replacement battery is not available, you
could temporarily use your car battery.
Once the AC power is restored, the battery will
recharge automatically, unless it is old or
damaged. The alarm will remain on until the
GRAY button is pressed for 1 second.
In the event that your Pro Series sump pump
system has pumped for an extended period of
time, the battery may be very depleted. In this
condition, when the AC power is returned to the
unit, a battery alarm will continue to sound. The
battery may need a longer period to recharge.
Press the GRAY button for 5 seconds to silence
the alarm.
If the battery is completely discharged, an
internal safety feature will not allow the
charging system to activate. Call the Glentronics
service department for instructions or replace
the battery.
If the battery is relatively new and the battery
alarm is activated, before you replace the
battery, call the Glentronics service department.
The phone number is 800-991-0466, option 3.
TO CLEAN THE BATTERY TERMINALS
AND CABLES
Risk of electrical shock or battery explosion,
which can cause serious injury of death. Wear
eye protection. Work in a well-ventilated area.
Do not smoke or allow a spark or flame in the
vicinity of the battery. Avoid dropping metal
tools on the battery. If battery acid contacts
eyes, flush with water for 10 minutes. Review
the safety instructions on page 1.
1. Unplug the power cord from the wall outlet.
2. Remove the cover of the battery box by
pushing in the tabs on the front and back,
then lifting up.
3. Fan the area around the top of the battery
with a piece of cardboard (or another non-
metallic material) to remove any hydrogen or
oxygen gas that may have been emitted from
the battery.
4. Unscrew the wing nuts. Remove the battery
cables and clean the battery posts with a
battery post terminal cleaner or a wire brush.
5. Clean the corrosion off of the ring connectors
on the ends of the battery wires. Use a stiff
brush or sandpaper.
6. If the fluid sensor has come out of the
YELLOW battery cap, replace it now. Then
replace the battery cables, WHITE to the
NEGATIVE (-) post, and BLACK to the POSITIVE
(+) post. Tighten the wing nuts.
7. Plug the power cord into the wall outlet. (You
can provide additional protection for the
control unit by using a surge protector.)
REPLACING THE BATTERY
Risk of electric shock or battery explosion,
which can cause serious injury or death.
Wear eye protection. Work in a well-
ventilated area. Do not smoke or allow a
spark or flame in the vicinity of the battery.
Avoid dropping metal tools on the battery.
If battery acid contacts eyes, flush with
water for 10 minutes. Review the safety
instructions on page 1.
