INSTALLATION INSTRUCTIONS
QUICK INSTALLATION & BATTERY ESSENTIALS
Pump Sentry™ is designed to operate with an external battery or battery bank
whose nominal operating voltage is 12V, and whose single or combined A-
Hr. rating does not exceed 250 A-hr. A full recharge will take 13 hours or 30
hours for batteries of 100 A-hr. and 250 A-hr. respectively. Pump Sentry™
will maintain batteries at full charge while electricity is available. See page 13
of this manual to learn more about the charger function indicators.
BATTERY TYPE
Only batteries conforming to Battery Council International (BCI) group size
27 or larger are recommended (up to size 31). Only deep cycle batteries are
designed for the type of service which Pump Sentry™ requires. INSTALL
ONLY deep cycle batteries. (wet cell or AGM type) The marine-variety is
acceptable. DO NOT use car batteries. (See page 8 for some suggested
sources.)
BATTERY BOX
Your selected battery(ies) should be installed in a high quality plastic or metal
battery box that comes with a lid that is designed for said box. It is available
at the point of battery purchase.
BATTERY CABLES
Use only the cables furnished with Pump Sentry™ that are packaged in its
carton. They are equipped with the terminations necessary for reliable and
solid connection.
The ends with the blade terminals mate with the RED and BLACK battery
cable connectors on the Pump Sentry, while the other ends are furnished with
Ring terminals designed to fit over the wing nut posts of most batteries.

How The Pump Sentry Works
When electricity is present, the Pump Sentry™ charges a 12-volt battery and
surveys the power line. At the instant that a power failure occurs, the Pump
Sentry converts the energy stored in the battery to AC power to operate your
pump. When AC utility power is restored, the Pump Sentry automatically
switches your pump back to AC utility power, recharges the battery, and
monitors the power line.
While the Pump Sentry is a sophisticated electronic device, it should not be
expected to perform beyond its limitations, and extreme care should be taken
to insure safe operation within specifications.

WARNING:
RISK OF ELECTRICAL
SHOCK
In the event of a short circuit,
grounding reduces the risk of
electrical shock by providing a
safe path to ground. The Pump
Sentry must be properly grounded.
The Pump Sentry is equipped with
a cord having a ground wire with
an appropriate three pronged plug.
The plug must be used with an
outlet that has been installed and
grounded in accordance with all
local electrical codes and
ordinances. Where a two pronged
wall outlet is encountered, it must
be replaced with a three pronged
outlet by a qualified Electrician to
reduce the risk of shock, the third
prong must not be cut off the plug.
DO NOT attempt to defeat this
safety feature.
Use Pump Sentry only with
adequate wiring that is up to
electrical code specifications.
Connect to properly grounded
outlets only.
WARNING:
RISK OF ELECTRICAL
SHOCK
The Pump Sentry is capable of,
and intended to generate electrical
voltage when unplugged from a
wall outlet or when AC power is
shut off.
Because Pump Sentry uses batteries to
generate 120 volts of AC power, both
the batteries and the power cord must be
disconnected to neutralize the Pump
Sentry. Failure to disconnect both the
batteries and the power cord could result
in electrical shock sufficient to cause
injury or death
FAILURE TO COMPLY WITH THE ABOVE WARNINGS COULD
RESULT IN INJURY OR DEATH

 Do Not block either the fan
or the exit air ports of the
Pump Sentry. Allow at least
2 inches of air clearance on
all sides. Any room in which
the Pump Sentry is mounted
should have adequate
ventilation.
UNDER NO
CIRCUMSTANCES
Should the Pump Sentry be
mounted in a confined area or in
a sump pump pit or crock.
 Pump Sentry is not only an
electrical appliance, but also
produces a potentially
dangerous and hazardous
electrical current even when
a power outage occurs. It is
safe when installed and used
properly. Keep children
away.
WARNING! The Pump Sentry has several components with
electrical contacts that switch electrical currents. Opening or
closing any of these electrical contacts can produce a spark that
could ignite an explosive air mixture. To prevent fire or
explosion, do not install the Pump Sentry in any area which
might contain flammable liquids or gases. Do not install Pump
Sentry in the same confined area as the battery box.

 Remove power cord from
the AC wall outlet to
simulate a power failure.
The fan will not necessarily
be activated. It is thermostat
controlled and will turn only
when the temperature of the
wall of the stove sentry
exceeds 45C (113F).
 Cycle the pump to ensure
operation in “battery back
up” mode.
 Plug the Pump Sentry AC
power cord back into the
wall outlet. Cycle the pump.
Note that after 2 seconds at
least one of the Battery
Monitor LEDs has lit. This
is normal and is an
indication that the Pump
Sentry has recognized the
return of normal AC power.
The Pump Sentry is no

12
longer in “battery back up”
mode and has returned to its
normal state of charging the
battery and providing line
power.
CHANGING
THE
BATTERY
If for any reason the battery needs
changing, it is important to follow
the steps below, in the order shown
to avoid damage to the Pump
Sentry unit.
1. Turn the ON/OFF switch
on the Pump Sentry to the
OFF position.
2. Unplug the input power cord
of the Pump Sentry from the
AC outlet.
3. Unplug the input power cord

DISCONNECTING
BATTERY CABLES.
5. Replace the battery.
6. Reconnect the Pump Sentry
following the steps under
the heading MAKING
CONNECTIONS.
MAINTENANCE
Once properly connected, the
Pump Sentry requires no
maintenance. When AC power
fails, it will automatically convert
battery power to AC power for
operation of the pump. It will
automatically recharge the battery
when AC power returns. During
all of these times and power
transitions, the Pump Sentry
requires no manual adjustments.
SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE.

13
Charger Function s
The smart charging system in Pump Sentry is microprocessor controlled to yield optimum charging rates
and long battery life.
When the electrical source is restored allowing the resumption of the charging process, there is a 2
second delay during which the charge state of the battery is assessed. After this delay, the bottom of the
two LED indicators comprising the battery monitor will illuminate. These LEDs inform the user
regarding the state of the battery:
LED State of Battery
Bottom LED “Flashing” - The battery is in the process of recharging.
Bottom LED “On” - The battery is fully charged.
Replace Battery LED - When batteries age to the point where they can maintain their fully
charged state only for short periods of time, it is an indication that their capacity
has decreased. They no longer have the ability to sustain their loads as they did
when they were new. The Pump Sentry detects this degradation causing the
Replace Battery LED to illuminate. When the battery reaches below 50% of its
new battery state, this condition is detected by the monitor. Other LED’s may be
lit at the same time.
Figure #1 on page 14 shows the Battery Monitor LED array.
Uninterruptible Power Indicator
The “Power Output” indicator shown in Figure #1 informs the user that AC power is present at the
output receptacle providing power to the load. This LED is applicable to both the standby (AC line
power present) and Back Up (Battery Power) states.
This LED will be extinguished in the following situations:
a) The main fuse is blown (in the Standby or Back Up states). See Section on Fuses (Page 15)
b) The battery is exhausted (in the Standby state)
Figure #1 on page 14 shows the location of this Uninterruptible Power Indicator.
Fan Operation
The air-intake fan, located adjacent to the red DC cable terminal, is thermostat controlled. It operates
only when the internal surface of the Pump Sentry exceeds 100F. This eliminates unnecessary fan
operation thereby minimizing battery loading.

How to Discern When Pump Sentry is Operational in the Backup Mode
When all LED’s of the battery monitor are OFF, and the pump sentry is plugged into an AC outlet, the
unit is in the back up mode. In this mode when there is sufficient energy in the battery to operate the
system, the uninterruptible power LED is illuminated. Once the battery is depleted the uninterruptible
power light will extinguish, indicating an absence of AC power at the Pump Sentry’s output.
How to Discern When Pump Sentry is Operational in the Standby (Line Power) Mode
When at least one of the Battery Monitor LED’s in ON, and the pump sentry is plugged into an AC
outlet, the unit is in standby mode. In this mode, the uninterruptible power LED remains illuminated.
Fuses
Figure #2 on page 14 shows the location of two protective fuses F1 and F2.
F1, the charger fuse, provides protection against charger or battery catastrophic failure. When this fuse is
blown the pump sentry will operate on standby power only until the battery is depleted.
F2, the main fuse, provides secondary protection against severe overload. When this fuse is blown, 120
VAC to the output receptacle of the pump sentry is cut off. In this state, the Uninterruptible Power LED
will be OFF. Replace fuses only with the types indicated on the fuse rating label of your unit which can
be found next to the fuse holders on the flat side of the unit to the left of the line cord.
Audible Alarm
While operating on Battery Backup Power, when the battery is depleted to the point where it dips below
10.8V, a high pitched audible alarm is emanated from the Pump Sentry. This is a sign, to the user, that
he will imminently loose battery power. If the maintenance of battery power is crucial, the user may
substitute the spent battery for a fully charged one, by carefully following the directions in the section
“Changing the Battery” on page 12.
If the audible alarm is found to be irritable, it may be turned off by simply turning off the ON/OFF
switch of the pump sentry. IT IS IMPORTANT TO TURN THIS SWITCH BACK “ON” WHEN THE
UNIT’S OPERATION IS REINSTATED. This should take place when utility power comes back on or
after the battery has been replaced. FAILURE TO DO THIS WILL LEAVE THE USER WITHOUT
BACK UP PROTECTION.
