1. Inspect and test the system for proper operations at least
every 3 months.
(a) Red power on indicator light should be “on” indicatingAC
power is on.
(b) Unplug primary pump and the control charger from power
supply.
(c) Fillsumpwithwatertothe“on”levelfortheDCpump.Allow
pump to run a few minutes.
(d) The alarm will sound approximately 5 seconds after the
pump starts to run.
(e) Push alarm reset switch.The alarm will go “off”.
(f) Pump will shut off after water level is lowered and the float
drops to the off position.
2. Plug the control charger and the primary pump into the wall
outlet.
(a) The primary pump will come on and lower the water to the
normal operating level and shut off.
(b) The “yellow” charging light should be on. The charger is
replacingthe energy consumed during thetest.The “green”
light will come on after the charger has replaced the energy
consumed during the test.
3. Batteryshouldbeagitatedgentlyevery3months.
Battery acid is dangerous. Take proper safety precautions. Do
notsplashtheacid.Adddistilledwatertobatterywhennecessary
per battery manufacturer's instructions.
1. Charging and charged LED’s alternate frequently.
(a) This is normal.
2. DC Pump won’t run.
(a) Check 15 amp fuse in line from pump to switch (see fig. 5).
If fuse is blown, replace with 15 amp Littelfuse type 3AG,
series 311.
(b) Check for proper connections.
(c) Check all wire terminal points. Clean if required.
(d) Check for low battery. Service battery if required.
3. Pump runs but pumps very little or no water.
(a) Check for low battery. Battery will recharge if Red power
“on” light indicates power has been restored and the float
switch is in the off position.
(b) If immediate usage is required, remove and replace dead
battery with a full recharged battery.
(c) Due to varying conditions the pump may continue to run
on a low battery without sufficient power to remove wa-
ter. Pump will not stop running until battery is completely
discharged.
(d) Weak batteries can be recharged but
may not store sufficient energy for full service.Aweak
recharged battery can only be detected by reduced pump-
ing time or by checking each cell with a hydrometer. If your
emergency pump system is used frequently the battery
should be checked by a qualified battery dealer.
4. Pump cycles too frequently.
(a) Check positions of rubber stops on float rod.
(b) Adjust upper rubber float stop as required. Recommended
for standard installation.
5. Float switch in “on” position. Pump won’t run.
(a) Remove pump. Check for obstruction in pump preventing
impeller from rotating.
6. Pump runs, but pumps water intermittently.
(a) Pump is air locking. Check flow of water incoming to
sump. If water is entering the sump at a high velocity cre-
ating a turbulent condition, a mixture of air and water may
cause a complete or partial air lock and reduce or stop the
flow of water in the discharge pipe.
(b) Baffle the incoming stream of water to reduce turbulence.
Diverting water stream against wall of basin usually cor-
rects an air lock problem.

The DC controller is equipped with a 10 amp charger for maintaining the battery in a ready state and recharging the battery after use when
AC power is restored. Time for recharge depends upon the amount of power consumed by the pumping cycle during the AC power inter-
ruption. The pump may go back to the ready run position in a very short period of time.Acompletely drained battery may require up to 24
hours for full recharge. If after 24 hours of charging the battery has not reached 6 volts, the alarm will sound and not reset until the battery
is brought up to a voltage of 6.5-7.0 volts. © Copyright 2009 Zoeller Co. All rights reserved.

Checklist
Performance
The DC emergency pump system requires a good quality, 12 volt battery to obtain maximum pumping time during a power outage.Adeep-
cycle, 12 volt, 105 amp-hour marine battery or larger is recommended and will provide approximately 7½ hours of continuous pumping
time in a sump pump installation with 8' of head pressure. In most installations the pump runs intermittently and the battery life is extended
accordingly.Batteries with top terminals are recommendedfor easeof installation.These batteries contain acid and proper precautionmust
be taken when handling. Maximum battery size 12½" Length x 7" Width x 9½" Height.

Installation
movedon the discharge pipe orthe rubber stops can beadjusted
as necessary. Cut extra float rod length below lower float stop to
prevent debris from interfering with float operation.
12. If the old primary pump discharge piping is being replaced with
PVC piping, duplicate the old pipe dimensions and use the exist-
ing drainage connection. If the primary pump and backup pump
isanewinstallation,thedrainageconnectionmustbedetermined
and the discharge pipes fitted accordingly. Solvent weld the up-
per portion of the discharge pipe into the PVC tee outlet (see
figures 1 and 2). Connect the discharge pipe into the drainage
connection. The pipe must be supported from above to ensure
adequate support for the pump assembly. Reinstall pumps in
sump pit with discharge back to its original position.
13. Install DC control charger (see figure 3) by using the wall bracket
and anchors provided. If more convenient, the control charger
may be set on a nearby shelf or ledge. The control charger
should be located 3 or 4 ft. above the sump. To reduce noise
from vibration, it is recommended that the charger be anchored
with the wall bracket provided.
14. Connect the leads from the control charger to the battery termi-
nals. Red pos. (+) lead to positive terminal and black neg. (-)
lead to negative battery terminal. Upon proper connection, test
alarm will sound. Press alarm reset to silence. This indicates
proper charger to battery connection. Correct
battery hook up is essential for operation of the system. Use
wing nuts supplied with battery and eyelet connectors on battery
wireleads. Thepositiveterminalis the larger stud, 3/8" diameter.
The smaller stud, 5/16" diameter is the negative terminal. Apply
grease to the terminals to help prevent corrosion.
15. Connect the black lead from the pump to the negative (-) battery
terminal. Connect the white or red lead from the pump to the
white lead from the switch. This connection is made at the fuse
installedon theswitchwire (see figure3). Connectthe blacklead
from the switch to the positive (+) battery terminal.
16. Connect the blue sensor wire to the sensor connector (figure 3).
17. Close battery box and secure cover with the safety closure strap
provided. Carpeted or wood barrier between the battery case
and the floor is recommended.
18. Plugthecontrolpowercordintothe115Vwall outlet. Theprimary
sump pump and the control box should be on separate circuits.
19. Reconnect power to primary sump pump.
1. The preferred method of installation for backup pumps is shown in
figures 1 and 2. The installation kit includes the necessary fittings
andonecheckvalveforinstallingwiththebackup pumpdischarg-
ing into the primary pump outlet pipe. An additional check valve is
incorporated in the discharge of the backup pump.
2. Remove all parts from shipping carton and make sure all parts are
included. Refer to checklist on page 3.
3. Select location for battery and control charger. Control charger
must be within 6' of a 115V wall outlet and within 6' of pump and
basin. Connect to a separate circuit, different than the primary
pump.
4. Ifprimarypumpis installed,disconnectpower. Iftheprimarypump
is a column pump with adjustable float, and you are installing per
figure2,checkthe“on”pointandadjusttoapproximately7½"from
bottom of pump (see figure 2). Mark the discharge pipe 7" above
the “on” point of the primary column pump or 7" above the top of
the primary submersible pump.
5. If existing discharge pipe is metal or flexible tubing, it will need to
be replaced with SCH. 40 PVC piping. Use a male adapter for
connecting to the primary pump outlet.
6. Remove the discharge pipe and cut off at the mark determined in
step 4. Remove an additional 8" from the bottom portion.
7. Screw the discharge pipe into the primary pump outlet. Tighten
with strap wrench.
8. Assemble discharge fittings per figure 4. Note: Pump must be
glued into tee fitting on a 30° angle to avoid air locking (see figure
4). Rotate pump while gluing until the line on the discharge is
facing up. Use a commercial grade of PVC cleaner and solvent
cement (not furnished with kit) on the socket joints.
9. Install the pump and discharge assembly per figure 1 or 2.
10. Assemble the float assembly per figure 5.
11. Install the float switch assembly bracket above the outlet tee using
the clamp provided (see figures 1 and 2). Make certain the clamp
is tight on the pipe to avoid slippage. Use electrical tape below
the clamp to help prevent the clamp from moving. Ensure that the
“off” level of the float is 1" min. above the discharge tee of the DC
backup pump (see figures 1 and 2). Position pumps in the sump
and move float up and down, making sure of free movement with-
outinterference from any obstructions inside thesump or lid. Very
shallowsumps mayrequiresome adjustmenttoavoid overfillingor
backing up of water into the sump inlet. The float switch can be

a Water/Acid Deep-Cycle Battery which can run the pump continuously for over 7½ hours, and a Maintenance-Free AGM Battery, which will
power the pump for over 3½ hours. These times are based on continuous pumping at 10' of static head.Actual times will vary depending on
static head, volume of water entering the pit, and the condition of the battery.
Follow these recommendations:
• Use a B.C.I. size 27 deep-cycle battery, 175 minute reserve capacity, or larger.
• Do NOT use a “maintenance-free” battery unless it is a Gel-filled orAGM battery.
• Replace your battery every 3 years.
• Do not let corrosion build up on the battery terminals.
• Do not place your battery on a concrete floor where it will discharge faster.
• To check specific gravity, follow the instructions on a hydrometer (not applicable for Gel orAGM batteries).
PROTECT YOUR WARRANTY:
• Water level in batteries must be checked once a month (not applicable for Gel orAGM batteries).

Carbon Monoxide Detectors
Whether you have a “Basement Sentry®” Backup Pump System, or a competitive brand, all use batteries that give off gaseous by-products
whencharging. Some of these by-products can produce arotteneggodor.Also, some of these by-products can causeaCOdetectortofalsely
activate. In order to help prevent false activation, Zoeller Company recommends moving the battery as far apart from the CO detector as pos-
sible or, if necessary, vent the battery to the exterior. Zoeller Company provides the previous statements only as guidelines to help prevent
falseactivation of the CO detector. In no way aretheymeanttosupersede the instructions that accompany the detector nordo theysupersede
advice from the CO detector manufacturer.
If the audible alarm associated with your CO detector is activated, we recommend the following actions:
1) Take immediate action for personal safety as recommended in the CO detector literature.
2) Contact the appropriate agency to determine if the CO is being produced by your furnace, water heater, or any other device which uses
natural gas.
3) Ifyouarecertain thatno COisbeingproduced,then achargingbatterymaybe producinggaseous by-productswhicharecausingtheCO
