2-3 STORAGE BEFORE USE

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.

PRODUCT 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™ inter-
face 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.

BATTERY 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 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.
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.
