When you fill the battery for the FIRST time,
it will be the ONLY time you add acid to the
battery. In the future, when the fluid level is
low, add distilled water to the cells. Never
add more acid.
System Connections
Risk of electrical shock or battery explosion,
which can cause serious injury or death.
Unplug the main AC pump to avoid electrical
shock. 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.
MOUNTING THE CONTROLLER
When you position the battery with the control
unit on the top, be sure the charger cord will
reach the AC power outlet, and the pump cable
and float switch will reach the bottom of the
sump. Position the unit in a well-ventilated
area. (Diagram C)
1. Mounting the backup control unit: (a)
Thread the wires on the backup controller
through the hole in the top of the battery
box. (b) Secure the controller to the top of
the battery box by lining up the Velcro strips
and pressing them together.
2. Connecting the backup pump: Remove the
security tag from the pump and plug the
pump wires into the pump connector on the
back of the control unit.
3. Installing the battery fluid sensor:
Remove the cover of the battery box and 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. (a) If you have battery A,
replace the battery cap that is 2nd from the
POSITIVE (+) post of the battery with the
battery cap that is provided in the Basement
Watchdog package. An arrow on the top of
the battery marks this position. There are
two holes in the battery cap. Insert the
fluid sensor in the hole that is off-center on
When you fill the battery for the FIRST time, it
will be the ONLY time you add acid to the
battery. In the future, when the fluid level is
low, add distilled water to the cells. NEVER add
more acid.
If your battery looks like the battery above,
follow these directions.
1. Remove the cover of the battery box by
pushing the tabs on the front and back of the
box and lifting up. Place the battery box on
the floor. Place the dry (unfilled) battery into
the battery box.
2. Remove the two battery caps by carefully
prying them up with a screwdriver. Place the
screwdriver in the groove in the middle of the
cap on the top of the battery. DO NOT lift the
cap by prying it up from the groove on the
side of the battery. It may damage the vent.
3. Carefully push in the perforated tab at the top
of the acid pack. Lift up the large tab and
pull out the dispensing hose. Hold the hose
upright above the pack and squeeze the hose
forcing all the acid back into the pack.
4. Position the acid pack and battery as shown
at the right. Pinch the end of the hose
together and cut off the tip. Insert the end
of the hose into each cell. Control the flow
by pinching the hose with thumb and
forefinger
. Fill each cell of the battery to a
level just covering the battery plates, and
then go back and top off each cell equally.
It is important to have all of the cells filled
equally or the battery will not operate
properly. The acid should reach a level about
1/4” below the cap rings. You may top off
each cell with a little distilled water, if
necessary. DO NOT OVERFILL THE BATTERY.
(Diagram B)
A newly filled battery will sometimes require
additional acid after about ten minutes.
Reexamine the fill level and add additional acid,
if necessary. The battery acid may bubble at this
time and give off a sulfur-like smell, but this is
normal. After the battery has been filled, press
the two caps on the top of the battery.
The battery will be charged 70%-80% 30 minutes
after adding the acid. The system will then finish
charging the battery. During this time the alarm
may sound.
