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 10 minutes. Review the safety
instructions on page 1.
Position the control unit in a secure place
approximately 4 feet 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 anything
on top of the battery. Do not place anything on
top of the control unit. (Diagram F)
1. 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 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 6 inches
above the water level line in the sump pit.
(a) Attach the float switch very securely to
the discharge pipe with the plastic wire tie.
(b) If the pump is stacked above the main AC
pump in a narrow sump pit, the float may be
attached to the elbow of the pump. 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.
3. Installing the battery fluid
sensor: 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
n
on-metallic material) to remove
any hydrogen or oxygen gas that
may have been emitted from the
battery. Replace the battery cap
that is 2nd from the POSITIVE
(+) post of the battery with the
YELLOW 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.
If you are not using the Basement Watchdog
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 then the
BLACK wire to the POSITIVE (+) post. Replace
the wing nuts and tighten.
