INSTALLING THE BACKUP PUMP:
Sump pump ON level must be lower than the backup
pump ON level. Set the backup pump switch higher
than the primary switch.
1. Place the pump into the pit. Secure the dis-
charge piping and attach the switch to the pipe.
Make sure the switch ON level is at least 4 inches
below the top of your pit and it is set at a level
higher than the primary switch’s ON level. Once
in place, tighten the switch clamp securely to the
pipe.
2. Once the switch is set in place and the di charge
piping is properly installed, you can piggy back
plug the pump and the switch into the receptacle
located on the StormPro power supply. Then
plug the power supply into the wall outlet.
3. Test run your system on AC power by activating
the switch, then unplug the power supply from the
electrical outlet and test the pump on DC power
by activating the switch. Be sure to plug the
power unit plug back into the wall outlet.

4. If battery voltage falls below a usable charge,
PUMP WILLSTOP:
• Power loss (inverter on) light OFF
• Battey charging light FLASH
• Fully charged light OFF
5. Battery voltage may recover and allow brief peri-
ods of Operation.
To test the Unit simply unplug it from the receptacle
add water to sump until pump pumps sump down.
Only run the Pump supplied with the Battery Back-
Up System for a few cycles. You can repeat this if
you wish but it is not necessary. If the Unit works the
first time it is sure to work time and time again. Be
sure that you remember to plug the Unit back into the
receptacle after you have completed the test. NOTE:
If while testing the Unit the Pump does not turn on,
the following steps should be taken:
1. Check the charger and inverter lights to see if
they are on.
2. Check the circuit breaker.
3. Plug the Pump you have plugged into the Unit
directly into a live building receptacle. If the Pump
runs, recheck all the battery connections, and
battery voltage.
4. Check sump water level to see that Pump is be-
ing required to run.
