BATTERY BACKUP SYSTEM (BBU)

INSTALLATION AND OPERATION

NOTICE:

• 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.

NOTICE: Study pages 4-6 to determine which installation

method will be best for you. The “Separate Discharge”

(Figure 2, Page 4), installation is recommended.

NOTICE: 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,

Page 4) option.

NOTICE: 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.

Personal injury and flood hazard. Do not

turn the pump on until all the fittings are glued and the

glue has dried. Loose fittings can explode off of pipes

and cause personal injury and flooding.

Risk of electrical shock. At the circuit breaker

or fuse box, turn off the electrical power to the sump

pump before beginning this installation.

Setup

1. Locate the high water level in your sump pit (the

water level at which the existing (primary) sump

pump starts - see Figure 1). Turn off power to pump

and mark this point on the discharge pipe with a

pencil or marker.

2. Drain the sump pit as far as possible without running

the pump dry. Do this by:

A. Piggyback switch: Unplug the pump and switch

from the outlet, then unplug the pump from the

piggyback switch. Reset the circuit breaker or

reinstall the fuse and plug the pump directly into

the outlet. The pump will start. Drain the pit and

unplug the pump. OR

b. No piggyback switch: Reset the circuit breaker

or reinstall the fuse and use a non-conducting

broom handle or stick to raise the float switch;

the pump should start. Drain the pit and then

release the switch.

3. When the pit has drained, turn off (open) the circuit

breaker or remove the fuse again to avoid electrical

shock while working on the installation.
