Operation
Before performing any wiring to sump
pump disconnect power to pump.
1) Plug FloodAlert into a 120-volt
grounded wall outlet.
2) Insert the battery jumper (See
Figure 2).
3) Plug grounded pump into Flood-
Alert outlet.
4) Run the sensor wire to the sump
and fasten using wire ties. Its
tip should be at the level where
you want the pump to begin
operating.
SETTING THE RUN TIM­ER
The run timer sets the pumping depth
and how much water you prefer to
pump out of the pit. It does not start
timing until the water level drops
below the sensor wire. The moment
the water drops below the sensing
wire the run timer starts limiting
the pumps run time. Initially set the
time to 5-seconds. Test the operation
by filling the sump pit with water
until the sensor wire is below water.
The timer should be set so that the
pump turns off before the water level
reaches the pump’s inlet. If the water
level reaches the pump’s inlet, it will no
longer pump water. If a pump has an
inlet on the bottom side of the pump
and the water level is low enough to
allow air into the pump, an air-lock­
condition may occur. Air-lock­ happens
when air is trapped in the pump and
can not escape. Air-lock­ condition can
be avoided if the water level stays
above the pump’s inlet. Adjust set-time
to remove desired amount of water
and to avoid an air-lock­ condition.
BATTERY
The jumper on the cover connects the
battery to the circuitry. If the unit loses
power the battery runs the alarm and
sensor. It should be replaced every year
or when a power loss occurs for over
two days.
To replace battery:
Purchase a 9-volt alk­aline battery.
Unplug the pump from the unit and
unplug the unit from the wall outlet.
Remove the battery jumper. Remove
the 4-screws holding the cover. Remove
the cover from the base by using a
rock­ing motion to free the receptacle
from its slide on tabs. Unsnap the
old battery and snap in the new one.
Replace the cover mak­ing sure to press
hard on the receptacle to slide it fully
onto its 3-tabs. Replace the 4-screws
holding the cover. Plug the unit into
the wall outlet and the pump into the
unit. Replace the battery jumper.
Do not
plug
unit in with the cover removed. High
voltages are present.
WATER SENSING
EST measures the surface area of
liquid contacting two metals. Since the
sump is grounded for safety reasons,
something metal in the sump must be
grounded. This might be the pump
case, the sump itself, or on a plastic
pump, it’s motor shaft. The sensing
wire is the other metal. EST senses the
square inches of contact between the
two metals and their distance. The
purpose is to ignore thin water films
that might coat the surface of a wire
or pipe and only detect the main body
of water. It does not detect resistance
and touching the sensing wire to
ground does not activate it.
OIL FILM­S
EST is able to break­ apart oil films that
might coat its sensing probe. Oil films
float on the surface of water adhering
to the surface of metals preventing
them from mak­ing electrical contact
with the water. EST’s tiny fast moving
electronic pulses move non-conductive
liquids away from the probe, busting
them apart if they manage to coat it.

WATER LEVEL
Water seek­s its own level but
compacted soil causes it to deviate to
the path of least resistance. As a result
ground water will not rise at a uniform
level across your entire basement.
A sump pump pit must not only be
deep enough, but more importantly
maintain a low enough water level to
insure that the path of least resistance
remains underground and not across
the top of your basement floor. An
empty sump draws more groundwater
from surrounding areas than a full one.
Experience shows this to be roughly a
4:1 ratio; a 1-foot below grade peak­
water level draws from only a 4-foot
radius while a 3-foot below grade peak­
water level extends this out to 12-feet.
A common error is setting the water
level as high as possible to minimize
pump cycling and later noticing that
water surfaces some distance away.
Zcross technology in FloodAlert allows
you to set the water level as low as
practical without worrying about high
cycle operation.
