INSTALLATION
1. Mount the power unit on the wall at least 36 inches off the floor and within 3 feet of a 120 VAC electrical outlet.
Secure to the wall studs or anchor securely to a block wall. Make sure to keep all sides of the power unit clear of
obstructions by at least 12“. DO NOT PLUG THE POWER UNIT INTO THE 120VAC OUTLET AT THIS TIME.
2. Connect the BLACK battery lead to the BLACK terminal on the power unit. Tighten the terminal retention knob
securely by hand. Do not use any tools to tighten as this may break the retention knob.
3. Connect the RED battery lead to the RED terminal on the power unit. Tighten the terminal retention knob securely by
hand. Do not use any tools to tighten the terminal retention knob as this may break the retention knob.
4. Connect the BLACK battery lead to the BLACK terminal on your 12 VDC Deep Cycle Battery. Secure the connection
per the battery manufacturer’s recommendation.
5. Connect the RED battery lead to the RED terminal on your 12 VDC Deep Cycle Battery. Secure the connection per the
battery manufacturer’s recommendation.
6. Plug the power unit into the 120 VAC outlet.
7. Confirm that the Charger Switch and Power Switch are in the “OFF” Position. Plug your sump pump into either of the
two 120 VAC Output Power Outlets.
8. Turn on both the Charger Switch and the Power Switch. The LEDs above both switches should be green. Your system
is now properly setup.
TROUBLESHOOTING
WARNING
Always disconnect the power unit from power sources before handling. This guide is designed to help identify reasons
for potential operating problems. It is not a service guide. Dismantling of the power unit voids warranty. Servicing of
power unit should be referred to the factory or its authorized service centers.
NOTE: The manufacturer assumes no responsibility for injury or damage associated with disassembly or modification of
the power unit. Consult with customer service before attempting any disassembly.
PUMP DOES NOT RUN OR HUM.
1. Power Unit Fuse/Overload Protection tripped or loose. Check / replace fuse.
2. Water level in pit may be too low to activate switch. Add more water to pit.
3. Plug on power cord may not be making contact in receptacle. Check security and connection.
4. If the pump is using the series (piggyback) cord plug, the plugs may not be connected tightly together.
5. Float may be obstructed. Make sure float is free and not interfering with the pit wall or other obstruction.
6. If all symptoms check OK, the motor winding may be open. Consult factory.
TEST
To verify that your system is setup properly to operate in the event of a power failure:
1. Unplug the Power Unit from the 120VAC Outlet.
2. Lift the float switch on your sump pump. The pump should operate normally. The Power Unit is now converting the
12VDC from your battery into a pure sine wave 120 VAC output to your pump.
3. Plug your Power Unit back into your home’s 120 VAC Outlet.
