Éviter de faire tomber des objets en métal
sur les bornes de la batterie: cela pourrait créer des étincelles ou des
courts-circuits du système ou de la batterie, provoquant une explosion.
Installation may take several hours. Have
appropriate means of removing water while sump pumps are disabled.
INSTALLATION
1. Turn power to main pump off.
2. Pump must be installed using 1-¼ in. or 1-1/2 in. rigid PVC
piping.
The backup pump can be installed with a separate dedicated dis-
charge line (Method 1), or tied into an existing sump pump line with
a check valve (Method 2).
Unplug the existing AC pump. Failure to follow
this warning could result in fatal electric shock.
Débrancher la pompe c.A. Ne pas respecter cet
avertissement pourrait entraîner un choc électrique mortel.
1. Verify that the existing AC pump is in good working order. If the
AC pump is questionable, it is typically recommended that the
unit be replaced with a 1/3 HP or 1/2 HP pump.
2. Remove any silt or accumulated debris from the sump pit and
surrounding area.
METHOD 1 (PREFERRED)
1. Locate the backup pump on a solid, level surface in the sump
pit. Do not place the pump on a loose or sandy surface. Small
stones or sand may damage the pump resulting in potential
pump failure.
2. This pump has a 1-1/2 in. NPT discharge. If a 1-1/4 in. dis
charge pipe is desired, an adapter (not included) will be
necessary. Smaller diameter piping will reduce pump flow, rate
and performance.
3. Cut a 4 ft. section of 1-1/2 in. or 1-1/4 in. diameter rigid PVC
pipe. Cement pipe to a threaded fitting. Cement pipe into pipe
coupling. Attach pipe section to the backup pump discharge
adapter.
4. Screw on to pump discharge.
Be careful NOT to strip or cross thread plastic
fittings or check valves. Flex hose is prohibited. Rigid PVC or metal pipe
is required for permanent installation.
5. Place the pump with the 4 ft. section of PVC pipe on a solid,
level surface in the sump pit on an elevated surface.
6. Attach the required rubber check valve (sold separately) to the
top of the discharge pipe. This will allow the pump or check valve
to be removed easily for servicing.
NOTE: Check valves can be placed directly in the pump discharge
if desired. However, for ease of disassembly, it is recommended
that check valves be placed above the sump as shown in Figure 1.
The remainder of the discharge pipe installation will vary depend-
ing on individual circumstances. Using sound plumbing practices,
route the discharge pipe to an exterior wall by the shortest path.
Keep turns to a minimum because they reduce flow output of the
pump. The pipe that exits the building structure should be sloped
downward so that water will not freeze in the pipe.
When installing the separate discharge pipe, drill through the
outside wall with appropriate drilling equipment. Seal the hole to
prevent water from entering.

Method 2
If a separate, dedicated discharge is not possible as in Method
1, the backup pump can be tied into the AC operated pump's
discharge pipe by installing a "Y" connector. Two check valves will
be required.
1. Locate the backup pump on a solid, level surface in
the sump pit. Do not place the pump on a loose or
sandy surface. Small stones or sand may damage the
pump resulting on potential pump failure.
2. This pump has a 1-1/2 in. NPT discharge. If a 1-1/4 in.
discharge pipe is desired, an adapter (not included) will
be necessary. Smaller piping will reduce pump flow,
rate and performance.
3. A check valve is required in the discharge line
of BOTH the Main AC pump and the backup pump to
prevent recirculation of water into the sump pit.
4. Cut a 4 ft. section of 1-1/2 in. or 1-1/4 in. diameter rigid PVC
pipe. Cement pipe to a threaded fitting. Cement pipe into pipe
coupling. Attach pipe section to the back-up pump discharge
adapter.
5. Screw on to pump discharge.
Be careful NOT to strip or cross thread plastic
fittings or check valves. Flex hose is prohibited. Rigid PVC or metal pipe
is required for permanent installation.
6. Place the pump with the 4 ft. section of PVC pipe on the
sump floor or on an elevated surface if required.
7. Attach the required rubber check valve (sold separately) to the
top of the discharge pipe. This will allow the pump or check
valve to be removed easily for servicing.
8. Duplicate the discharge piping arrangement for the
primary AC pump if the discharge line has to be
adjusted to accomodate a second pump.
9. Glue a 45º elbow to the short pipe on the back-up
pump. Glue a "Y" adapter to the short pipe on the
existing pump, as shown in illustration for Method 2.
10. Glue a short piece of PVC pipe between the 45º elbow
and the "Y".
NOTE: Check valves can be placed directly in the pump
discharge if desired. However, for ease of disassembly, it is
recommended that check valves be placed above the sump as
shown in Figure 2.
The remainder of the discharge pipe installation will vary depending
on individual circumstances. Using sound plumbing practices, route
the discharge pipe to an exterior wall by the shortest distance.
Methods 1 and 2
Install float switch at least 10 in.-12 in. above bottom of sump pit
so that backup unit turns on only when the water level is higher
than the normal "on" level for main pump. Use the hose clamp
provided to secure the switch to the discharge pipe. Make sure
power wires do not interfere with float switch, pump inlet, or main
pump operation. Backup pump must not be allowed to run dry.
Control Box Installation
1. Place battery in box, attach red cable to positive battery
post and black cable to negative battery post.
if cables are reversed, damage to the control box
or battery will result, and void warranty .
MISE EN GARDE
Si les câbles sont inversés, la boîte de
contrôle ou la batterie pourrait être endommagée et la garantie annulée.
2. Plug the float switch, pump and transformer into the
appropriate connectors. The connections are all unique and
cannot be interchanged.
3. Put lid on box, and place the battery within six feet of the
sump and a 115 VAC separately fused outlet. The outlet
must be protected by a ground fault circuit interrupter (GFCI).
The area must also be clean, dry and well ventilated.
Do not allow battery box to get wet, or expose it
to moisture. Electronics will be damaged and void warranty.
MISE EN GARDE
Ne pas laisser le coffre de la batterie être
mouillé ou exposé à l’humidité. Les appareils électroniques seront
endommagés et la garantie sera annulée.
4. Test pump operation by filling the sump with water while the
main pump is unplugged. If the pump operates properly, plug
the transformer into the GFCI protected outlet to begin charg
ing the battery.
5. Protect electrical cord from sharp objects, hot surfaces, oil and
chemicals. Avoid kinking the cord. DO NOT USE PUMP WITH
DAMAGED CORD.
Operating Instructions and Parts Manual

OPERATION
Always disconnect the power source before
attempting to install, service, relocate or maintain the pump. Never
touch sump pump motor, water or discharge piping when pump is
connected to electrical power. Never handle a pump or pump motor
with wet hands or when standing on wet or damp surface or in water.
Fatal electric shock could occur.
Toujours débrancher le cordon
d'alimentation avant d'essayer d'installer, de réparer, de
déplacer ou de faire l'entretien de la pompe. Ne jamais
toucher le moteur de la pompe de puisard, l'eau ou les
tuyaux d'évacuation lorsque la pompe est branchée à une source
d'alimentation électrique. Ne jamais manipuler une pompe ou le moteur
d’une pompe avec les mains humides, ou debout sur une surface
mouillée ou humide ou dans l’eau. Cela pourrait occasionner un choc
électrique.
Risk of electrical shock! Use a GFCI receptacle
to reduce the risk of fatal electric shock. Cutting the cord will void the
warranty and make the pump inoperable.
Risque de choc électrique! Utiliser une prise
avec disjoncteur de fuite à la terre pour réduire le risque de choc
électrique. Couper le cordon annulera la garantie et rendra la pompe
inutilisable.
1. After installation, the backup pump will start when
the water level rises above the backup float switch.
2. The control box has a DC charger designed to shorten the
recharging time of your battery, and to prevent overcharging.
In addition, the control box has a time delay which keeps the
pump from repeated, short cycles when it shuts off. The time
delay feature will allow the pump to run 20-25 seconds after the
switch reaches the off position.
3. The control box contains multi-colored indicator lights. When
AC power is present, the lights will indicate the charging state,
and not reflect actual battery voltage, particularly with a defec-
tive battery. In order for the indicator light to provide an accu
rate reading, steps "a" through "d" must be followed.
Unplug main ac pump and the transformer. Risk
of electrical shock!
Débrancher la pompe principale et le
transformateur de courant c.A. Risque de choc électrique!
a. After main pump and transformer are unplugged, a power off
alert tone will sound for 30 seconds.
b. Press and release the self test button to activate the backup
pump.
c. When the pump stops, read the charge indicator lights:
Green: Indicates the battery is fully charged.
Yellow: Indicates battery is partially charged, but still operable.
Red: Battery is completely discharged or defective.
Red blinking: Battery discharged below level where pumping
can occur. Motor is locked out by controller until battery is
suficiently charged to run pump.
d. Plug in transformer and main AC pump. When main AC power
is out, and when pump has been running, the lights will indi-
cate battery status.
4. A chirping sound from the control box will accompany the red
light, indicating that the battery may require attention or
replacement. Voltage is only an indicator of battery condition
and may not reflect the true condition of the battery. See
maintenance for instruction on assessing battery condition.
5. A single thirty (30) second tone will sound when power to
the system is interrupted and the bottom power failure light
will illuminate. The unit will reset and the light will go out
automatically when power is restored.
6. A three (3) second tone will sound every time the pump starts.
