GENERAL INFORMATION
The Battery Backup Combo Kit is pre-plumbed up to the hose
and clamp assembly. The system includes the primary sump
pump (PSP), backup sump pump (BSP) assembly, and vertical
float switch. The unit is equipped with two check valves - one
for the primary pump and one for the backup pump.
The battery backup pump is not a substitute for your primary
sump pump. It is designed to temporarily backup your primary
sump pump during a power outage or other problem which
prevents normal operation of the primary pump. Do not use
this system to pump flammable liquids or chemicals. Pump
clear sump water only with this pump. For residential use only.
Keep the battery charger dry and protected from damage.
This system is designed to work with either a sealed lead-acid
AGM battery or a flooded lead-acid battery. Use of a true Gel
Cell (often confused for AGM) or a standard automotive battery
with this charger is not recommended. An automotive battery
may require charging after only 1-2 hours of continuous use,
and the repeated charging cycles may cause early plate failure
in the battery.

BACKUP ASSEMBLY INSTALLATION
Attach backup pump assembly to primary pump. To do so,
un-screw bottom nut on check valve and remove rubber seal.
Place nut from check valve around discharge PVC pipe on
primary pump, then place rubber seal. Attach backup pump
assembly to the primary pump by tightening nut to the rest
of the check valve unit. Adjust backup pump to sit at an angle
(approx. 10°).
FLOAT SWITCH INSTALLATION
Assemble float switch as shown.
COMBO UNIT INSTALLATION
Suggested Materials Needed: Screwdriver, tape measure,
hacksaw, cable ties.
1. Drain the sump pit as far as possible without running the
pump dry. Do this by:
 Piggyback switch: Unplug the pump and switch from
the outlet, then unplug the pump from the piggyback
switch. Reset the circuit breaker or reinstall the fuse
and plug the pump directly into the outlet. The pump
will start. Drain the pit and unplug the pump. OR
 No piggyback switch: Reset the circuit breaker or
reinstall the fuse and use a non-conducting broom
handle or stick to raise the float switch; the pump
should start. Drain the pit and then release the switch.
 When the pit has drained, turn off (open) the circuit
breaker or remove the fuse again to avoid electrical
shock while working on the installation.
 Unplug existing sump pump and place power cord and
piggyback switch out of the way of work and water.
2. Measure height of MBSP-2C Combo Kit from base to top of
hose clamp assembly. Subtract 1”.
Drop the tape measure into the bottom of sump pit and
mark the cut line on the discharge pipe (1” less than total
height of the Combo Kit).
3. Use hacksaw to cut horizontally along cut line completely
through pipe.
NOTICE: Depending on where your current check valve is
located, there may be excess water. Let the water drain/
drip into the sump pit.
4. Remove old sump from sump pit.
NOTICE: Remove all sand, clay, and gravel before
installing.
5. Place Combo Kit into sump pit. Make sure vertical float
switches can operate freely inside sump pit.

6MY1013 (03-30-2021)
6. Once the Combo Kit is firmly seated in the base of the
pit, connect the hose and clamp switch to the existing
discharge pipe and clamp it securely.
7. Secure power cord (PSP & BSP), piggyback switch, and
reed switch cord high up and around pipe with a cable tie.
Plug the primary pump into a standard household 15 amp
outlet.
NOTICE: The circuit should be dedicated to the sump pump
exclusively.
Remember: Do not handle the pump while it is plugged in;
whether it is running or not.
8. Connect BBU. See “BBU Wiring and Setup”.
9. Once all wiring is complete, fill your pit with water and
verify that the PSP removes the water and the BBU doesn't
run. Then, unplug your PSP and refill your pit with water.
Verify that the BBU removes the water.
10. Make sure that the power is on to both pumps, and your
system is ready to use.
OPERATION
Risk of electric shock. Can shock, burn or kill. Do not
handle a pump or pump motor with wet hands or when standing
on wet or damp surface, or in water.
1. Shaft seal depends on water for lubrication. Do not operate
pump unless it is submerged in water as seal may be
damaged if allowed to run dry.
2. Motor is equipped with automatic reset thermal protector.
If temperature in motor should rise, switch will cut off all
power before damage can be done to motor. When motor
has cooled, switch will reset automatically and restart
motor. If protector trips repeatedly, pump should be
removed and checked. Low voltage, long extension cords,
clogged impeller, very low head or lift, or a plugged or
frozen discharge pipe, etc., could cause cycling.
3. Pump will not remove all water. If operating a pump
manually and suddenly no water comes out of the
discharge hose, shut off the unit immediately. The unit has
broken prime due to a very low water level.
Risk of electric shock. Can shock, burn or kill. Before
attempting to check why unit has stopped operating,
disconnect power from unit.

BBU WIRING AND SETUP
1. Connect the positive (+) charger/controller lead wire
(red) to the positive (+) battery terminal (red). Connect
the negative (–) charger/controller lead wire (black) to
the negative (–) terminal (black) on the battery. If you are
using two batteries, use the set of optional terminals and
connect the second battery. Use lead wires (not included)
to connect the positive (+) charger/controller terminal
to the positive (+) battery terminal and the negative (–)
charger/controller terminal to the negative (–) battery
terminal.
2. The backup pump leads are polarity sensitive; connect
the positive pump lead to the terminal labeled Pump ‘+’
and the negative pump lead to the terminal labeled Pump
‘–’. NOTICE: If the leads are reversed, the pump will run
backward and not pump water.
3. The float switch leads are not polarity sensitive; connect
the float switch leads to the ‘Float Switch’ tabs on the
charger/controller.
4. Test the float and the pump by lifting and holding the
float. The ‘Pump Status’ LED will light continuously and
the buzzer will beep steadily. The pump should start
after 3 seconds. If the pump does not run, check all the
connections and remake them as necessary.
5. To stop the pump, lower the float; after 25 seconds the
pump should stop, the ‘Pump Status’ LED should flash, and
the buzzer should beep.
6. With the pump operating, test the ‘SILENCED ALARM’
button; hold for one second; release. The ‘Silenced
Audible Alarm’ LED should illuminate and the buzzer
should stop sounding. To reset the buzzer (allow it to
sound) and extinguish the ‘Silenced Audible Alarm’ LED,
press the ‘Silence Alarm’ button again for one second.
Depress the ‘System Test’ button; hold it for one second;
release. The ‘Pump Status’ LED should stop flashing.
NOTICE: During normal operation, the flashing ‘Pump
Status’ LED indicates that the pump has run in your
absence.
7. Press and hold ‘System Test’ button. All LEDs will light up,
pump will run and buzzer will sound. Release the button
and LEDs should go off, pump should stop, buzzer should
stop.
8. The ‘Battery Status’ LED indicates the battery capacity
when the A.C. power is off.
 Continuously ON - the battery voltage is above 10.9
Volts Direct Current (10.9VDC) and capacity is above
20%.
 Slow Beep/Slow LED Flash - the battery’s capacity is
between 0 and 20%.
 Fast Beep/Fast LED Flash - the battery is severely
discharged. The battery will continue to charge (as
long as the 115V AC power to the charger is on) at the
rate of .5 AH until the battery’s charge is above 20%.
When the first warning occurs (slow beep/slow flash),
you will have approximately 2 hours (or less) of pump
operation left. The actual time of operation will
depend on the condition of the battery and may be as
little as 15 minutes.
9. Connect the Power Supply cable (supplied) to the Charger/
Controller’s Power Input jack.

BATTERY REQUIREMENTS
Hazardous electric current. Can cause severe
burns and start a fire if the battery terminals are short
circuited. Install the battery in the battery case. To prevent
accidental shorting across battery terminals, close and latch
the battery case securely. Do not leave the battery uncovered.
Do not allow children to play around the battery backup
system installation.
The performance of your backup sump pump depends on
the battery used with it for power. We recommend using
our BAT40. You can also use a group 24M or 27M Deep Cycle
battery. They will provide acceptable performance and will
stand up well to long periods of little or no use.
This system is designed to work with either a sealed lead-acid
AGM battery or a flooded lead-acid battery. Use of a true Gell
Cell (often confused for AGM) or a standard automotive battery
with this charger is not recommended. An automotive battery
may require charging after only 1-2 hours of continuous use,
and the repeated charging cycles may cause early plate failure
in the battery.
Use only lead-acid batteries. This unit is not designed to use
with Li-Ion, NiMh, NiCAD, Liquid Polymer, etc.
Use only the recommended battery or one of the same type
and size so it will fit in the battery box (maximum size: 13” long
x 7” wide x 10” tall (330.2mm x 177.8mm x 254mm) including
terminals) and supply enough voltage for full performance.
BATTERY MAINTENANCE
Severe burn hazard. An acid-filled standard
lead-acid battery contains sulfuric acid. Avoid contact with
skin, eyes or clothing.
NOTICE: To protect the battery case from chipping and
gouging, do not let the battery sit on a concrete floor. Install
the battery on a shelf or protective pad (plywood, 2x4s, etc.).
Always install the battery in a dry location that is protected
from flooding.
PRE-QUALIFICATION TEST – 1 AND 2
Charger is charging at a very low level to try to bring a dead
battery back to life. If the battery is taking too long, try
resetting the charger once or twice (push the ‘System Test’ and
‘Silence Alarm’ buttons together to reset the charger).
Special Features: The charger is equipped with reverse
battery, short circuit, and “runaway charge” protection.
POSSIBLE PROBLEMS AND REMEDIES
1. Wrong Battery Voltage: Reconnect charger to a 12 volt
battery.
2. Reversed Battery Connections: Check all connections.
The negative (black) on the battery must connect to the
negative (black) on the charger, and the positive (red)
on the battery must connect to the positive (red) on the
charger. Reversing the battery connections will cause the
‘System Alert’ and ‘Silenced Audible Alarm’ LEDs to flash.
3. Thermal Runaway Condition: “Thermal Runaway” is the
technical term for the condition of the battery when some
(or all) of the cells have deteriorated to the point that they
won’t take a charge. In this case, replace the battery.
4. Charge Time Monitor – 1 and 2: Battery took too long to
complete its charge. The “Charge Time Monitor” will shut
down the charger after 84 hours of continuous charging.
Possible causes are:
 Pump ran for a long period of time during charging, or
 Battery is too large for the charger (including several
batteries connected in a parallel circuit).
EXCESSIVE BATTERY DRAIN
Pump may have run for a very long time, discharging the
battery. In this case:
1. If 115VAC power is OFF, the charger shuts down until the
power comes back on, but the pump will run as long as the
battery charge lasts. You may need to replace the battery
afterwards.
2. If 115VAC power is ON, the charger/controller continues to
try to charge the battery at a charging rate of .5 AH until
the battery charge is more than 20%, at which point the
charger will resume charging at a rate of 2 AH.
3. If the pump is running and the AC power is on, you may
need to stop the pump to allow the battery to charge.
Follow the battery manufacturer’s recommendations for
maintenance and safe use of the battery.

INFORMATION RELATIVE À LA SÉCURITÉ
IMPORTANTES CONSIGNES DE SÉCURITÉ
Ce manuel contient des consignes importantes qui doivent être suivies
pendant l’installation, l’utilisation et l’entretien du produit.
Ceci est le symbole d’alerte de sécurité. Si vous voyez ce symbole sur
votre pompe ou dans ce manuel, recherchez l’un des mots d’avertissement
ci-dessous et faites attention aux risques de blessures!
indique un danger qui, s’il n’est pas évité, entraînera la mort
ou des blessures graves.
indique un danger qui, s’il n’est pas évité, peut entraîner la
mort ou des blessures graves.
indique un danger qui, s’il n’est pas évité, pourrait entraîner
des blessures légères à modérées.
REMARQUE: Concerne des pratiques non liées aux lésions corporelles.
Lisez attentivement et suivez toutes les instructions de sécurité affichées
dans ce manuel et sur les pompes. Conservez les étiquettes de sécurité en
bon état. Remplacez-les si elles sont manquantes ou endommagées.
L’acide de batterie est corrosif. Évitez les éclaboussures sur la
peau, les vêtements ou le chargeur de batterie. Portez une protection pour les
yeux et la tête lorsque vous manipulez la batterie. Branchez et débranchez les
bornes de sortieCC uniquement après avoir débranché le chargeur de la prise de
courantCA. Ne laissez jamais les bornes de courant continu(CC) se toucher.
Tension dangereuse. Peut provoquer un choc électrique
grave ou mortel. Ne branchez ou ne débranchez pas le chargeur de batterie
lorsque vous vous trouvez sur un plancher mouillé ou dans l’eau. Assurez-vous
de garder une main libre lorsque vous branchez ou débranchez le chargeur. Si
le plancher du sous-sol est mouillé, coupez l’alimentation électrique du
sous-sol avant de marcher sur le plancher. Si la boîte d’arrêt est au sous-sol,
appelez la compagnie ou les autorités d’électricité pour arrêter le service du
domicile ou appelez votre service d’incendie pour obtenir des instructions.
Retirez la pompe et réparez-la ou remplacez-la. Le non-respect de cet
avertissement peut entraîner un choc électrique mortel.
Risque d’inondation. Ne faites pas fonctionner la pompe à
sec. Cela endommagera les joints et pourrait provoquer des fuites et des
dommages matériels.
Risque de choc électrique. Ne soulevez pas la pompe par le
cordon électrique, soulevez-la uniquement par le tuyau d’évacuation, l’anneau
de levage ou la poignée de la pompe. Soulever la pompe par le cordon peut
endommager ce dernier.
AVERTISSEMENT CONCERNANT LA PROPOSITION 65 DE LA
CALIFORNIE

chimiques considérés par l’État de la Californie comme pouvant causer le cancer,
des anomalies congénitales ou d’autres troubles du système reproducteur.
SÉCURITÉ GÉNÉRALE
1. Renseignez-vous sur l’utilisation, les limites et les dangers potentiels de
la pompe.
2. N’utilisez pas ce produit dans l’eau en présence de poissons. De l’huile
qui s’échappe du moteur peut tuer les poissons.
REMARQUE : Cet appareil n’est pas conçu pour être utilisé comme
pompe de cascade ou de fontaine ou avec de l’eau salée ou de la
saumure! L’utilisation avec des cascades, des fontaines, de l’eau salée
ou de la saumure annule la garantie.
3. Débranchez l’alimentation électrique avant de procéder à l’entretien.
4. Vidangez toute l’eau du système avant de procéder à l’entretien.
5. Fixez la conduite d’évacuation avant de démarrer la pompe. Une conduite
d’évacuation qui n’est pas bien fixée pourrait produire un effet de fouet,
causant des blessures corporelles ou des dommages matériels potentiels.
6. Vérifiez si les tuyaux sont en bon état et non usés avant chaque
utilisation pour vous assurer que tous les raccords sont bien serrées.
7. Inspectez périodiquement les composants du puisard, de la pompe et du
système. Gardez les débris et les objets étrangers à l’écart. Effectuez un
entretien de routine au besoin.
8. Assurez un moyen de décompression pour les pompes dont la conduite
d’évacuation peut être fermée ou obstruée. Relâchez toute la pression
du système avant de procéder à l’entretien d’un composant.
9. Sécurité personnelle:
 Portez des lunettes de sécurité en tout temps lorsque vous
travaillez avec des pompes.
 Gardez la zone de travail propre, dégagée et adéquatement
éclairée. Rangez tous les outils et tout l’équipement inutilisés.
 Gardez les visiteurs à une distance sécuritaire de la zone de travail.
 Faites en sorte que l’atelier ne présente aucun danger pour les
enfants en installant des cadenas et des interrupteurs, et en
retirant les clés de contact.
10. Conformez-vous aux codes de plomberie et d’électricité lorsque
vous installez le système. Il est recommandé d’utiliser un disjoncteur
différentiel de fuite à la terre (DDFT) lors de l’utilisation d’un appareil
électrique immergé sous l’eau.
11. Tout le câblage doit être effectué par un électricien qualifié.
12. Cet équipement uniquement destiné à être utilisé sur 115volts
(monophasé) est équipé d’un cordon à trois conducteurs homologué et
d’une fiche de mise à la terre à trois broches.
13. Une prise murale à deuxbroches doit être remplacée par une prise à
troisbroches correctement mise à la terre et installée conformément
aux codes et aux règlements applicables.
14. Assurez-vous que la source d’alimentation est conforme aux exigences
de votre équipement.
15. Protégez le cordon électrique des objets tranchants, des surfaces
chaudes, de l’huile et des produits chimiques. Évitez de plier le cordon.
Remplacez ou réparez immédiatement un cordon endommagé ou usé.
16. Ne touchez pas un moteur en marche. Les moteurs modernes peuvent
fonctionner à température élevée.
17. Utilisez cette pompe uniquement pour pomper de l’eau claire.
18. La pompe est dotée d’une lubrification permanente installée en usine.
N’essayez pas de la lubrifier!

uniquement.

20 MY1013 (03-30-2021)
RENSEIGNEMENTS GÉNÉRAUX
La trousse combinée de secours à batterie est déjà raccordée à l’ensemble
tuyau et au collier de serrage. Le système comprend la pompe de puisard
principale, l’ensemble de pompe de puisard de secours et l’interrupteur à
flotteur vertical. L’appareil est équipé de deux clapets de non-retour, un
pour la pompe principale et l’autre pour la pompe de secours.
La pompe de secours à batterie ne remplace pas la pompe de puisard
principale. Elle est conçue pour remplacer temporairement votre
pompe de puisard principale pendant une panne de courant ou tout
autre problème qui empêche son fonctionnement normal. N’utilisez
pas cette pompe pour pomper des liquides ou des produits chimiques
inflammables. N’utilisez que de l’eau de puisard claire avec cette pompe.
Pour une utilisation résidentielle seulement.
Gardez le chargeur de batterie au sec et protégez-le contre les dommages.
Ce système est conçu pour fonctionner avec une batterie scellée au
plomb-acide à séparateurs en fibre de verre microporeuse (absorbent
glass mat, ou «AGM»), ou encore une batterie au plomb-acide à
électrolyte liquide. L’utilisation d’une batterie à électrolyte gélifié
(souvent confondue pour AGM) ou d’une batterie automobile standard
avec ce chargeur n’est pas recommandée. Une batterie automobile
pourrait avoir besoin d’être rechargée après seulement 1 à 2heures
d’utilisation continue et les cycles de charge répétés pourraient entraîner
une défaillance prématurée des plaques d’accumulateur de la batterie.
