Product Operation
The dual float switch on the primary pump
contains two large floating rings enclosed within
a protective cage. Water will lift the bottom
float by ¼”, which will activate the pump. If for
any reason the lower float does not activate the
pump, the water will rise to the second float,
and it will activate the pump. As the pump
evacuates the water from the pit, the floats will
drop. The pump will run for an additional 10
seconds to extend the cycle after the lower float
drops. The blue controller for the primary pump
powers this switch.
During a power outage, or when more water is
entering the sump than the primary pump can
handle, the backup pump will automatically
begin pumping. It also has a dual float switch,
so if one float fails to activate the pump, the
second float will activate the pump as soon as
the water reaches that level. As the water
recedes below the float switch, a timer in the
control unit will run the pump an additional 25
seconds to empty the pit.
While the pumps are
active, water will come out
of the 1/8” hole that is
drilled in the pipe above
the pump. This is normal.
The hole is needed to prevent an air lock within the
system. Do not obstruct this hole or an air lock may
prevent the pump from activating, and the
basement will flood.
Batteries and sump pumps need maintenance.
The control unit on the backup system monitors
the battery and power conditions, and sounds an
alarm when maintenance is required. Following
is an explanation of the warnings and alarms.
Understanding the Warnings
and Alarms
The Pro Series control unit features a series of
warning lights that pinpoint potential problems.
In addition, an alarm sounds to alert you to the
problem. In some cases the lights and alarm will
go off automatically when the problem has been
solved. In others, the GRAY button must be
pushed to silence the alarm. Refer to the table
at the right for a quick review of the features and
their corresponding alarm status.
SILENCING THE ALARM DURING AN
EMERGENCY
If the alarm can be silenced before the problem
is corrected, you may silence it for two (2)
minutes by holding down the GRAY button for
one (1) second. The alarm will be silenced, but
the light will stay on. To silence the alarm for
24 hours, hold down the GRAY button for five (5)
seconds. It will automatically reset itself after
24 hours. The warning light will stay on.

Risk of electrical shock or battery explosion,
which can cause serious injury or death. Wear
eye protection. Work in a well-ventilated

If this warning light and alarm are on, you need
to add distilled water to the battery.
1. Unplug the control unit power cord from the
wall outlet.
2. Remove the cover of the battery box by
pushing in the tabs on the front and back,
then lifting up.
3. 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.
4. Then unscrew the wing nuts and remove the
battery cables and the fluid sensor from the
battery.
5. Pry up the two battery caps, or unscrew the
six battery caps depending on the
configuration of your battery. Add distilled
water to the battery filler bottle and replace
the nozzle. Place the nozzle of the battery
filler into each cell of the battery and press
down. It will fill the battery cell to the
correct level and stop automatically. If
distilled water is not available, tap water with
a low mineral content may be used. Well
water is not recommended. NEVER ADD
MORE ACID.
6. Replace the battery caps. Replace the fluid
sensor in the hole on the top of the battery or
in the yellow battery cap, depending on
