GENERAL INFORMATION
The battery backup sump system 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 water only with this pump.
Keep the battery charger dry and protected from damage.
This system is designed to work with a deep cycle sealed
maintenance free lead-acid AGM battery. It will also work with
a flooded lead acid battery. Gel and Sealed flooded lead acid
batteries are not recommended.
In an emergency (such as an extended power outage) which
depletes the system deep cycle battery, your automobile
battery may be temporarily substituted. Be sure to replace the
system deep cycle battery as soon as possible.
Use of an automobile battery instead of a deep cycle battery
in this system will significantly reduce the system’s total
performance. Automobile batteries are not designed for this
type of application and will be quickly ruined by the repeated
charge/discharge cycling.
NOTE
: This system is not designed for applications involving salt
water, brine, or where fish may be present! Use with these will
void warranty.

BATTERY BACKUP SYSTEM (BBU) INSTALLATION AND OPERATION
Install this system during a time when the primary pump will not
be needed.
Gather all supplies before starting.
Read all warnings and installation steps before you start.
Be prepared for water to leak from the coupling or piping when
disassembling or cutting the discharge pipe. Protect system
components, tools and supplies from getting wet. Dry any work
areas that get wet.
Study pages 5-8 to determine which installation method will be
best for you. The “Separate Discharge” (Figure 2), installation is
recommended.
NOTE:
Check your local codes and ordinances regarding waste
water disposal (especially when running the pump discharge
outside the house) before you start. The installation must
conform to all legal requirements.
If possible, install the BBU so that the discharge goes directly
outdoors (separate discharge pipe from the primary sump pump
discharge pipe). If this is not a practical option, see the “Common
Discharge” (Figure 3) option.
For ALL installations, once the installation is complete, run
both the primary sump pump and the BBU through at least one
complete cycle to make sure that everything operates correctly.
