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 backup system control
unit on the discharge pipe, be sure the charger
cord will reach the AC power outlet and the
pump cable and the float switch will reach the
bottom of the sump. Position the unit in a well-
ventilated area. Do not place anything on top of
the battery. (Diagram C)
1. Mounting the backup control unit: (a)
Thread one plastic cable tie through the two
mounting brackets on the back of the control
unit. (b) Secure the controller to the
discharge pipe by wrapping the tie around the
pipe and pulling it tight.
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 the top of the cap. Do not glue the sensor
into the cap. (b) If you have battery B, a hole
has been molded into the top of the battery to
accept the fluid sensor rod. The sensor hole is
marked by the label on top of the battery.
Hold the sensor straight and press it firmly into
the hole all the way up to the connector. Do
not bend the sensor rod.
If your battery looks like the battery above,
follow these directions.
1. If you have not purchased a battery box,
place a plastic garbage bag on the floor with
some paper towels or newspaper on top of it
while you are filling the battery. Place the dry
(unfilled) battery on top of the paper. If you
have purchased a battery box, place it directly
on the floor and place the battery in it.
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 up it from the groove on the
side of the battery. It may damage the vent.
3. (a) 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.
(b) Position the acid pack and battery as
shown below. 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 the cells filled
equally or the battery will not operate
properly. The acid should reach a level about
3/16” below the cap rings. (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.
Within 15-30 minutes of adding acid, the battery
will be 70-80% charged. The system will then
finish charging the battery. During this time, the
alarm may sound. This is normal.
Remove the paper and plastic bag from beneath
the battery. Roll it up with the plastic on the
outside and place it in the trash.
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.
