as long as the water is above the float. When
the water drops below the float switch, an
internal timer in the control unit will keep the
pump running an additional 25 seconds to
empty the sump pit. The switch should be
mounted about six (6) inches above the water
level line in the sump pit. Attach the float
switch very securely to the discharge pipe
with the plastic wire tie. Be 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!
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.
If you are not using a Basement Watchdog
Standby battery or if you are using a
maintenance free (AGM) 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. DO NOT apply
corrosion resisting sprays or pads to the
terminal rings or posts, since this could
prevent the battery from charging properly.
Be sure to slide the switch on the front of the
controller to the type of battery used with the
system (maintenance free or non-maintenance
free battery).
5. Connecting two batteries: If you are
connecting two batteries to the system,
before you replace the wing nuts, connect the
