Control Unit Hookup
1. Positioning the control unit:
Position the control unit in a secure
place approximately four feet (4´)
above the floor. Be sure the power
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 it on
top of the battery.
Do not place
anything on top of the control unit.

2. Selecting the main or backup
mode: The Basement Watchdog is
strong enough to be used as your
main and only pump, or it can be
used as a backup pump to support
your AC sump pump. If you are using
it as a MAIN pump, push the blue
button for 1 second to turn OFF the
“Pump was activated” alarm, or the
control unit will sound an alarm every
time the pump goes on. The RED
light next to the button should be lit.
If you are using the Basement
Watchdog as a BACKUP pump, push
the blue button for 1 second to turn
ON the alarm. The GREEN light will
be lit. In this mode the alarm will
notify you if the water rises high
enough to activate the pump. It may
be caused by heavy rains, a power
outage, or because your main pump
broke.
3. Positioning the float switch: The
float switch will turn on the pump
when the water rises to the top of the
switch, and it will remain running as
long as the water is above the float
switch. When the water drops below
the float, the internal timer in the
control unit will keep the pump
running an additional 30-40 seconds
to empty the sump pit. The switch
should be mounted six inches (6˝)
above the activation level of the main
AC pump. Attach the float switch
very securely to the discharge pipe
of the backup pump with a wire tie.
(If you are stacking the pumps in a
narrow sump pit, the float may be
attached to the elbow of the
Basement Watchdog backup pump.)
Make sure the switch is positioned
vertically with the mounting bracket
at the top. Do not tilt the switch. Do
not position the float switch on the
side of the discharge pipe facing the
drain tile or any incoming rush of
water! Do not position it next to the
power cord from the AC pump. 4. Installing the battery fluid sensor:
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
sump pump 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.
If you are not using the
Basement Watchdog Standby
Battery, you cannot use the battery
fluid sensor.
However you must
attach the sensor to the POSITIVE
(+) post of the battery or the alarm
will sound continuously.
The Basement Watchdog Sump Pump
System will not warn you if the fluid level
is low in this configuration. You will need
to check your battery every couple of
months to see if it needs water.
