1. Safety Information
RISK OF ELECTRIC SHOCK - Accidental contact with
electrically live parts, items, fluid, or water can cause serious in-
jury or death.
 ALWAYS disconnect BOTH the primary and backup pumps from their power sources before handling or making any adjust-
ments to either pump.
 Only qualified personnel should complete fixed wiring, battery and electrical connections, according to all local and national
electrical codes, during a pump installation.
 After installation, be certain that the pump is properly grounded, using its supplied grounding conductor. Use with a Ground
Fault Circuit Interrupter (GFCI) is highly recommended, even in areas where GFCI use is not mandated by code.
 During flood conditions, submerged electrical connections (including batteries) can energize the water. Always wear dielectric
rubber boots and other applicable Personal Protective Equipment (PPE) when water is on the floor and you must service an en-
ergized pump. DO NOT ENTER THE WATER if the water level is higher than that of the protection your PPE offers or if your
PPE is not watertight.
 NEVER lift or carry a pump by its power cord. This will damage the power cord, and could expose the electrically live wires
inside the power cord.
 DO NOT bypass grounding wires.
 The electrical power supply shall be located within the length limitations of the pump power cord, and for below grade installa-
tions it shall be at least 1.22 m (4 feet) above floor level.
 NEVER use this product in applications where human contact with the pumped fluid is common (such as swimming pools,
fountains, marine areas, etc.).

 During construction, if the pump is installed before its power cord can be plugged in or direct wired, the power cord must be
protected from the environment to prevent water from wicking through the cord end into the pump housing. If water enters the
pump an electrical short can occur from the pump to its surroundings, which will energize the surroundings.
RISK OF FIRE
 DO NOT use an extension cord to power the product. Extension cords can overload both the product and extension cord supply
wires. Overloaded wires will get very hot and can catch on fire.
 This product requires a separate, properly fused and grounded branch circuit, sized for the voltage and amperage requirements of
the pump, as noted on the nameplate. Overloaded branch circuit wires will get very hot and can catch on fire.
 NEVER use this product with or near flammable liquids. If the rotating elements inside this pump strike any foreign object,
sparks may occur. Sparks could ignite flammable liquids.
 DO NOT install this product in locations classified as hazardous or in explosive atmospheres as defined by any applicable safety
code.
 Keep battery in a well ventilated area, away from sparks and open flames. Batteries generate flammable gasses both charging
and discharging, which can explode or catch fire if ignited.
RISK OF SERIOUS INJURY OR DEATH
 The pump must be installed in accordance with all applicable codes and ordinances.
 DO NOT allow children to play with the pump.
 DO NOT allow children, or any person who is unqualified to use the pump. Any person who is unaware of the dangers of this
pump, or whom has not read this manual, can easily be injured by the pump.
 Wear adequate PPE when working on pumps or piping that have been exposed to wastewater. Sump and sewage pumps often
handle materials which can transmit illness or disease upon contact with your skin and other tissues.
 DO NOT remove any tags or labels from the pump or its cord.
 ALWAYS, keep clear of the pump’s suction and discharge openings. The rotating elements of this pump are designed to draw
in and pass foreign objects.
 NEVER, insert fingers into pump while it is energized. A stopped, energized pump may start without warning, via external test
features built into the control system.
 Wear adequate PPE when working with batteries. Batteries contain strong acids that can cause severe burns to skin and soft
tissues, if spilled. Prior to servicing your battery, refer to the battery manufacturers instruction manual or Safety Data Sheet
(SDS) for a listing of proper PPE, proper handling techniques, and proper spill response, to minimize your risk of injury.
 DO NOT touch the finned top surface of the charging unit. This surface becomes hot during normal battery charging may burn
exposed skin. Unplug the charger and allow it to cool prior to servicing.

 This pump and its floats have been evaluated for use with water only. Keep sump clear of debris. Debris can jam the pump and/
or its floats, resulting in flooding.
 DO NOT, use this pump as your primary sump pump.
 This pump should be placed on a separate, properly fused and grounded branch circuit, from the primary sump pump. This al-
lows your backup to continue to function and charge your battery, in the event your primary pump trips an electrical breaker
under normal operating conditions
 DO NOT use this product to pump corrosive liquids. Pump components can be damaged from corrosive liquids and cause prod-
uct malfunction or failure.
 NEVER dispose of materials such as paint thinner or other chemicals down drains. Doing so could chemically attack and dam-
age pump components and cause product malfunction or failure.
 DO NOT use pumps with fluid over 40°C. Operating the pump in fluid above this temperature can overheat the pump, resulting
in pump failure.
 DO NOT use pumps with mud, sand, cement, oil or chemicals. Pump components can be damaged from these items causing
product malfunction or failure. Additionally, flooding can occur if these items jam the impeller or piping.
 DO NOT modify the pump in any way. Modifications may affect seals, change the electrical loading of the pump, or damage the
pump and its components. Modifications can void your warranty on this product.
 DO NOT run this pump dry.
 Batteries and their chargers generate Carbon Monoxide (CO) during normal operation. To avoid nuisance alarms, make sure that
any CO detectors are a minimum of 15 feet away from this backup product. Please refer to your CO detector manual for more
information on installation.

2-3STORAGE BEFORE USE
Only place the pump in a wet pit when it can be operated. Water can wick
through the power cord into the pump causing an electrical short from the
pump to its surroundings.
 If it is necessary to store this backup pump system for a long period of time, it should be stored indoors in a clean, dry, tempera-
ture-stable environment. The pump, charger, and user interface should be covered for protection from dirt and water. All cable
ends must be protected against moisture.
2-4PRODUCT DESIGN
 While this pump has been designed to operate for long periods of time, it is not intended to be solely operated as a primary
pump.
 This backup pump has a check valve incorporated into the discharge of the volute, and therefore does not require the installation
of a check valve in the backup pump discharge line. However, if this backup is connected into the primary pump’s discharge
line, a check valve must be installed for the primary pump prior to the tee where the backup pump’s discharge connection is
made. See Section 2-6.
 This pump has been designed to directly accept a 1.5” pipe or street fitting to integrate into the discharge piping.
 You can test your battery backup pump with the push of button. Simply push the pump test button on your StormCell® interface
and your pump will run itself to verify that the pump is in working order.
 The float is easily installed: snap the float onto any 1.5” pipe, then adjust it to the desired height. The pipe clamp is made of
PVC; if desired, it can be glued in place on the pipe using PVC primer and cement.
 The communication cable between your user interface and battery backup charger is a standard shielded Ethernet cable. If you
wish to move your device more than 8 feet away from the charger, you can purchase a longer shielded Ethernet cable. Be sure it
is a shielded cable; it should have a metal wrap around the outside of the connector that makes contact with the Ethernet jack.
You can use the cable provided with your charger for an example of a shielded connector. DO NOT use a standard non-shielded
cable; use of non-shielded cables may cause communication issues between your charger and UI.
 This product has built-in high water level alarm functionality. In addition to sounding an alarm, the high water level float switch
will act as a redundant pump switch in the event that the primary 442 backup pump switch has failed. If this occurs (or any other
scenario occurs that results in the float switches operating out of order) the user interface and charger will signal a float fault.
 The backup pump interface has audible alerts that signal a low battery condition or that the 442 backup pump is running. If your
system is equipped with NightEye® functionality this information (and more) can be viewed from the associated mobile device.
Refer to NightEye® quick-start guide for more information.
2-5BATTERY SELECTION
 For the longest battery life, a deep cycle battery must be used with this backup system. Deep cycle batteries are designed to han-
dle multiple long deep discharges. For best results, install a Liberty Pumps StormCell® Battery with your backup pump.
However, if you choose to supply your own deep cycle battery, any 12V lead-acid battery may be used safely with Liberty’s
charging system.
 For greatest system capacity, deep cycle group 27 and 31 batteries are recommended. Larger batteries can be used, charged, and
maintained with this system, though these batteries will not fit in the Liberty supplied battery box. In the event of an extended
power outage, any charged 12 Volt DC car battery can be substituted for your deep cycle battery to prevent flooding. When
power returns, be sure to put your deep cycle battery back into service with your backup system.
Only use 12 volt lead acid batteries with this backup system. Use of
batteries with higher or lower output voltages, can damage your
backup up system, leak acid, or explode.

2-6INSTALLATION TYPES
If you have the ability to plumb a complete second discharge piping network for your new backup, this is the best possible installa-
tion, as it offers you an added backup solution in the event the primary pump discharge ever becomes blocked. To accomplish this,
install a 90° street elbow (included) into the 442 (tightening to 15 in-lb) and plumb a second line. Two alternate methods of installing
a 442 into existing primary pump piping are shown below.
Method B: Side-by-side Installation, a popular option in larger sump pits when it is desirable to have the backup pump and primary
pump on the same level. This installation will require a tee, a 90° elbow, and two sections of piping. A 90° street elbow is supplied.
Method A: Vertical installation is recommended for compact sump pits and sump pits where the buildup of sediment (rocks, sand,
mud, etc.) is an issue. The 442 comes with all fittings for this installation (included 90° street elbow is not used in this installation).

3. Mechanical Installation
Never work in a sump pit with energized pumps. Doing so is
an electrical shock hazard, and can result in injury or death.
Unplug all pumps, including primary pumps, prior to work-
ing on or installing this backup
1. Locate the level at which the primary pump activates by watching when the
pump turns on and measuring or marking the level in the sump.
2. Look at the supplied snap-on compact float and compare it to the image
shown to the right. The bumps on the left side of the LP lettering represent
the levels at which the switches inside the housing activate. Before cutting
your primary discharge piping, ensure that your float enclosure can be
mounted with the “Pump On” bump a minimum of 3” above the turn on
level of the primary pump, as measured in step 1.
3. Drain your sump pit to enjoy a clean, easy, and dry installation process.
Disconnecting and modifying the primary pump’s discharge piping is re-
quired to complete the installation of the 442. Complete this installation
during a time when the sump pit will not require pumping.
Instructions are continued by specific installation method below, as described in
Section 2-6. It is always recommended to do a ‘dry fit’ of piping, with no glue,
prior to gluing the piping in place. Be sure to not glue check valves closed.
Method A
4. Make a cut in the primary pump’s discharge piping above the primary
pump’s check valve. This cut will locate the tee used to install the 442
pump.
5. Install the tee and pre-glued nipple into the 442 pump discharge. Tighten
the hose clamp to 15 in-lbs, and mock up your 442 installation inside the sump pit without glue. Ensure that the 442 will not
interfere with the primary pump’s activation float.
6. Using a primer and glue approved for PVC use, glue the tee, nipple, and 442 assembly to the primary pump’s discharge pipe,
being careful not to glue the primary pump check valve closed.
7. Reinstall the remaining system discharge piping into the tee using an approved PVC glue and primer.
8. Install the compact snap-on float to the discharge piping, ensuring that the “Pump On” level is a minimum of 3” above the turn
on level of the primary pump. Use a small dab of PVC glue to secure the snap-on float to the discharge pipe.
Method B
4. Make a cut in the primary pump’s discharge piping above the primary pump. This will locate the tee used to install the 442
pump.
5. Install the supplied street elbow into the 442 pump discharge, with the street elbow facing the top of the pump. Tighten the hose
clamp to 15 in-lbs.
6. Install the tee, piping, and 90° elbow as depicted in the Method B image in Section 2-6, using PVC glue and primer and ensur-
ing that there will be no primary pump interference. Measurements for piping will vary by primary pump, system, and sump.
7. Reinstall the remaining system discharge piping into the tee using an approved PVC glue and primer.
8. Install the compact snap-on float to the discharge piping, ensuring that the “Pump On” level is a minimum of 3” above the turn
on level of the primary pump. Use a small dab of PVC glue to secure the snap-on float to the discharge pipe.

6. Operation, Repair, and Troubleshooting
6-1CHARGER AND PUMP OPERATION
The 442 backup pump will activate when the sump water level is high enough to actuate the “Pump On” float switch. The 442 back-
up pump run time depends on the Amp-hour capacity of the battery, the battery charge level, whether or not the charger has AC pow-
er, and the required equivalent vertical pumping distance.
Extended periods of operation (power outage, primary pump failure, etc.) may exhaust the battery. If this occurs, the charger will
recharge the battery when the period of extended operation ends. Recharge time from a “dead battery” state will be a minimum of 12
hours.

6-3 TROUBLESHOOTING OTHER ISSUES
Motor hums but pump does not run:
1. Battery charge has dropped below that which is required to run the pump. This can be temporarily rectified by swapping the
dead battery for a charged battery.
2. Check for jammed pump impeller.
Pump runs but pumps very little or no water / Pump cycles too frequently:
1. Ensure that check valve is installed and functioning between primary pump discharge and 442 connection tee.
2. Check for obstruction in discharge pipe.
3. Discharge pipe length and / or height exceeds capacity of pump.
Probable Symptom: Failed fuse, fuse LED illuminated, pump not running.
Check: Check all wiring connections, replace pump control fuse if required. Also,
verify that the pump has not jammed causing the fuse to fail. After fuse replace-
ment, test pump to confirm the problem is fixed.
Probable Symptom: Low battery alarm.
Check: Check all wiring connections. If AC power is out and the battery is
exhausted, it will charge upon return of AC power. If problem persists have the
12V battery tested.
Probable Symptom: Low battery alarm, pump not running.
Check: Check all wiring connections. If AC power is out and the battery is ex-
hausted, it will charge upon return of AC power. If problem persists have the 12V
