PRE-INSTALLATION
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.
