Liberty Pumps 441 is a battery back-up sump pump system with alarm. Operating from the power of a marine-grade deep-cycle 12V battery. It is designed to temporarily back up a primary sump pump during a power outage or other problem which prevents normal operation of the primary pump. The Liberty 441 is not intended to be used as the main sump water removal pump.Advanced Charging System of the Liberty Pumps 441 outperforms "trickle" chargers with a 5-stage charging process. The system tests the battery and maintains a maximum charge without running the battery down or selfdischarging. A sophisticated charging algorithm continuously tests the charging process from start to finish.This Battery Back-up Sump Pump System features time dependent charging with built-in 150-hour safety timer. If the safety timer "times-out," the red "Fault" L.E.D. is displayed and charging is discontinued to protect equipment from "run-away" battery under charge.NOTE Frequency of pump cycle, length of running time and pumping head will vary the lifetime of battery operation. Under a continuous-run situation the battery will last up to 4 hours and up to 30 hours in intermittent operation.Audible alarm and light advises of emergency pump operation. The alarm, located in the junction box, automatically sounds when the system runs if the alarm is in the "Enable" position. The alarm is silenced when the alarm switch is in the "Disable" position.There are two ways to install the Liberty 441 Battery Back-up Sump Pump. See included documentation.IMPORTANTDo not use this system to pump flammable liquids or chemicals.Pump clear water only with this pump.Keep battery charger dry and protected from damage.Automobile batteries are not designed for this type of application and may be substituted temporarily in an emergency. The Automobile battery will be quickly ruined by the repeated charge/discharge cycling. Use of an automobile battery will significantly reduce system total performance.
