When 120VAC household power is available to the Power Unit and the unit is powered ON ( Power Indicator is “GREEN”) ,
household power is directly routed through to both of the Output Power Outlets on this unit. While the CHARGER SWITCH
in the on position, the Power Unit is also charging the deep cycle battery. The Charging Indicator will be “RED” while
charging the battery and “GREEN” once the battery is fully charged. When you loose household power, the Power Unit will
automatically activate and convert your 12VDC Battery to 120 VAC Pure Sine Wave output at both of the Power Unit Outlets.
It is recommended that you keep both the Charger Switch and the Power Switch in the “ON“ position unless you are
changing the battery or performing other maintenance on the unit.
The STATUS INDICATOR LED will turn RED when the Power Unit is overloaded, overheating, low household voltage, or a
short circuit. See Troubleshooting Guide for more information.

INSTALLATION
1. Mount the power unit on the wall at least 36 inches off the oor 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. Conrm 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 modication 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 oat 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 oat 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.

TROUBLESHOOTING (CONTINUED)
PUMP RUNS OR HUMS BUT DOES NOT DELIVER WATER.
1. Check valve may be installed backwards or is defective. Check to make sure it is installed properly and apper in
valve is free to move.
2. Discharge line may be blocked or frozen. Check to see if line passes through cold areas or is blocked.
3. Vertical lift may be beyond pumps capability. See chart below for your pump’s maximum lift capability.
4. Check to see if inlet screen of pump is plugged or the impeller is jammed. Clean inlet and impeller as needed.
5. Pump Impeller may be jammed. Check for foreign material such as construction debris, stones, etc. that might
be preventing the impeller from rotating. Reminder: Make sure pump is disconnected from power source before
checking inlet and impeller area.
PUMP RUNS AND REMOVES WATER BUT DOES NOT SHUT OFF.
1. Float is stuck in the “on” position. Check to make sure the oat is free to move up and down without obstruction.
2. Switch may be defective. Consult factory.
PUMP RUNS BUT DELIVERS VERY LITTLE WATER.
1. Vertical lift is approaching the pump’s maximum lift capability. Refer to the above maximum lift chart.
2. Pump’s inlet is partially blocked. Check to make sure the inlet is clear of debris.
3. Discharge line is partially blocked. Check line for blockage.
4. Check valve is not opening all the way. Check for defective, reversed, or blocked check valve.
PUMP CYCLES TOO OFTEN OR RUNS CONSTANTLY
1. Check Valve may have failed causing discharged water to return to the sump pit. Cycle pump and look for water
rushing back through the pump inlet. Replace Check Valve as necessary.
2. Pump May be sized incorrectly. Check with your local plumber for recommendation.
3. Pump Inlet may be blocked. Unplug pump from power source and clean inlet.
SYSTEM STATUS LED IS RED
A RED Power Indicator LED is a sign of system trouble. Make sure that the cooling fans are clear of any obstacles and
debris. Check your household voltage to make sure it is at least 110 VAC. If you are using both outlets, make sure the
combined wattage does not exceed 1500 WATTS on a continuous basis. The Power Unit will automatically shut down, an
alarm will sound and the System Status LED will turn RED when the load exceeds 120% of the rated 1500 Watts.
LOW VOLTAGE ALARM
When the Battery voltage falls below 10.4 VDC, an audible alarm will sound to indicate that it needs to be recharged.
Make sure that the Charger Switch is in the ON position.
MAINTENANCE
The power unit should be checked frequently for debris and/or build up on the cooling fans which may interfere with
proper ow to cool the unit during operation. The cooling fans should be cleaned with a vacuum to remove any buildup at
least every 3 months or more frequently if the unit is mounted in a an area where excess dust or debris my be present.
Deep Cycle Batteries generally last between 3 to 5 years in a sump pump backup installation. It is recommended that the
battery is tested every 6 months to ensure it is ready for service.
