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!
2. Connecting the pump: Remove the security
tag from the pump and plug the pump wires
into the pump connector on the back of the
control unit. Keep the backup pump wire, the
AC pump wire, and the float wire separate
from each other. Do not let them cross on the
final installation.
3. Installing the battery fluid sensor:
BASEMENT WATCHDOG BATTERIES COME IN
TWO CONFIGURATIONS. THE HOLE FOR THE
FLUID SENSOR IS MARKED BY AN ARROW ON
THE TOP OF EACH BATTERY. Remove the cover
of the battery box by pushing in the tabs on
the front and back, then lifting up. 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 the top of the battery has six
small battery caps, replace the battery cap
that is 2nd from the POSITIVE (+) post 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 this 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 the top of the battery has
two large caps, place the fluid sensor in the
hole molded on the top of the battery. It is
located in the second cell from the positive
post, and the location is marked by an arrow
on the top label. Hold the sensor straight and
press it firmly into the hole. Do not bend the
sensor. You will not need the additional
battery cap provided in the carton if you have
this battery.
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. If the
battery dries out, the system will not work.
4. Connecting the battery: Remove the wing
nuts from the battery terminals. Remove the
security tag from the battery cables. Attach
the battery cables to the battery…the WHITE
wire to the NEGATIVE (-) post, and the BLACK
wire to the POSITIVE (+) post. Replace the
wing nuts and tighten them.
5. Connecting two batteries: If you are
connecting two batteries to the system,
before you replace the wing nuts, connect the
additional cable to the two batteries….the
BLACK wires to the POSITIVE (+) posts and the
WHITE wires to the NEGATIVE (-) posts of each
battery. NEVER attach one end of the positive
wire to the positive post and the other end of
the positive wire to the negative post on the
other battery.
