Fuse
Unplug the main AC pump before servicing the
backup pump to avoid electric shock. Failure
to do so could cause serious injury or death.
This alarm indicates that the 20 amp safety fuse
on the back of the control unit has blown. This
can be the result of a clogged pump motor, or
pump wires that have been shorted out. To
determine the problem:
REFER TO THE PHOTOS AT LEFT
1. Check the pump plug in the back of the unit
to make sure it is firmly connected. Check the
pump wires to make sure they are connected
securely to the pump plug. Check the rest of
the pump wires for any possible breaks.
2. If the pump wires are intact, the pump may be
clogged. (a) Disconnect the charger from the
wall outlet, and disconnect the battery cables.
(b) Release the union and remove the pumps
by the handle on the primary pump. (c) Clear
any debris from the strainer, and then
reconnect the pump to the discharge pipe.
(d) Connect the control unit, and the battery
cables to the battery…the BLACK wire to the
NEGATIVE (-) post, and then the RED wire to
the POSITIVE (+) post. Tighten the wing nuts
on the battery posts. (e) Plug the charger
back into the wall outlet.
3. (a) Check the DC fuse by pulling it out of the
fuse holder. (b) If the wires are burned and
broken, replace the fuse with a 20 amp DC
safety fuse. If the fuse blows again, unplug
the computer control unit from the wall and
disconnect the battery cables from the
battery. Then call Glentronics technical
support for instructions at 800-991-0466,
option #3. You may need to replace the
pump.
4. Plug the main AC pump back into the wall
outlet.

Risk of electrical 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 15 minutes and get prompt
medical attention. Review the safety
instructions on page 1.

If this warning light and alarm are on, you need
to add distilled water to the battery. Battery
fluid levels should be checked once every four
months.
1. Unplug the charger and the blue AC pump
controller 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. Then unscrew the wing nuts and remove the
battery cables and the fluid sensor from the
battery.
5. Remove the battery caps. Add distilled water
to each cell. If distilled water is not
available, tap water with a low mineral
content may be used. Well water is not
recommended. NEVER ADD MORE ACID. Fill
the battery to level 2 as shown in Diagram B
on page 4. (The Basement Watchdog battery
filler will automatically fill the level to the
correct height. See enclosed order form.)
6. Replace the battery caps. Replace the fluid
sensor in the hole on the top of the battery.
Be sure the fluid sensor is positioned in the
2nd cell from the positive post. The hole is
marked with an arrow. Replace the battery
cables…the BLACK wire to the NEGATIVE (-)
