Fan keeps turning on in AC mode

1. The fan is thermally controlled to turn on when the internal temperature of the unit
   reaches 112 - 120 Deg. F (45 - 50 Deg. C).

Inverter Mode but No Power

1. Check display to see if a low battery
   condition is present. Remove all loads,
   unplug the AC power cord for 10 sec. and
   plug it back in. Allow the battery to charge
   when the AC Power resumes before
   running the Inverter on battery again.
2. Check display to see if fault condition is
   present.

Inverter Does Not Operate and No Message On Display

1. Push and hold Power button on front of the unit for 3 - 5 seconds.
2. Check the battery connections and the mains connections

Inverter Trips Frequently In DC Mode

1. Reduce the load and reset the inverter. 
   1. Inlet holes in pump base may be
      clogged. Remove pump and clean the
      openings.
   2. Pump impeller may be partially clogged
      with tar or paint, causing motor to run
      slow and overload. Remove pump and
      clean.
   3. Motor stator may be defective.

Pump Does Not Run In DC Mode

1. Possible low battery.
   1. Check conditions of batteries and
      recharge.
2. Possible loose or corroded battery
   connection.
   1. Check and clean all connections.

AC Power Is Available but the Inverter Will Not Operate in AC Mode

1. Push and hold Power button on front of the
   unit for 3 - 5 seconds.
2. Possible loose AC output connection.
   1. Check all AC output connections.
   2. Check main 15 amp circuit breaker to the wall outlet.

Low Surge Power

1. Possible weak batteries or battery cables are too long.
   1. Refer to cable and battery recommendation in this manual.

Inverter Overheats

1. Inverter is hot.
   1. Reduce load and let the inverter cool down.

If Pump Does Not Run and Hums

1. Inverter circuit breaker is off.
2. Water level in sump has not reached turn
   on level.
3. Pump cord is not making contact in receptacle.
4. Switch may not be working properly.
   1. Plug pump directly into wall outlet
      without the switch plug. If pump runs,
      the switch may need to be replaced.
5. If all of the above are OK, then the motor
   could be malfunctioning.

Pump Runs but Does Not Deliver Water

1. Check valve is installed backwards. Arrow on valve should point in direction of flow.
2. Discharge shut-off valve (if used) may be
   closed.
3. Impeller or volute openings are fully or partially clogged. Remove pump and clean.
4. Pump is air-locked. Start and stop several times by plugging and unplugging cord. Check for clogged vent hole in pump case.
   Drill a 1/8 inch hole into PVC pipe.
5. Inlet holes in pump base are clogged.
   Remove pump and clean the openings.
6. Vertical pumping distance is too high.
   Reduce distance or change the discharge
   fittings of the pump.

Pump Runs and Pumps Out Sump but Does Not Stop

1. Unplug the pump/switch plug from the inverter.
2. Plug the pump back into the switch plug
   and plug the switch plug into a wall outlet.
   1. If the pump does not turn on right away, and the water level is not at the
      On level, let the pump go through an On / Off cycle a few times to insure
      that the switch is functioning properly. The basin may need to be filled with
      a garden hose or bucket. Plug pump/switch plug back into one outlet on the
      inverter and test again.
   2. If the pump turns on right away, and the water level is not at the On level,
      the switch may have to be replaced.

Pump Runs but Only Delivers a Small Amount of Water

1. Pump may be air-locked. Start and stop several times by plugging and unplugging
   cord. Check for clogged vent hole in pump case. Drill a 1/8 inch hole into PVC pipe.
2. Vertical pumping distance may be too high. Reduce distance or change the discharge
   fitting of the pump. Inlet holes in pump base are clogged. Remove pump and clean the
   strainer and openings.
3. Impeller or volute openings may be fully or partially clogged. Remove pump and clean.
4. Pump impeller is partially clogged with tar or paint, causing motor to run slow and overload Remove pump and clean.

Fuse Blows or Circuit Breaker Trips

1. Pump impeller may be partially clogged with tar or paint, causing motor to run slow
   and overload. Remove pump and clean.
2. Motor stator may be defective.
3. Fuse size or circuit breaker may be too small. Must be 15 amp.
4. Impeller or volute opening may be fully or partially clogged. Remove pump and clean.

Motor Runs for a Short Time Then Stops

1. Inlet holes in pump base may be clogged. Remove pump and clean the openings.
2. Pump impeller may partially clogged with tar or paint, causing motor to run slow and
   overload. Remove pump and clean.
3. Motor stator may be defective.

Pump Does Not Turn On

1. Test the pump without the Ion+ switch/alarm.
   1. Plug the pump directly into a wall outlet, without plugging it into the Ion+ switch/alarm plug.
   2. If pump still does not run, the pump may be defective.
   3. If the pump does run, continue to the next step.
2. Test the Ion+ switch/alarm with the pump.
   1. Plug the pump into the Ion+ switch/alarm and plug the Ion+ switch/alarm plug into the wall outlet.
   2. Push up on the sensing plate through the center hole on the underside of the switch. Note that, being an electronic switch, you will not hear a clicking sound.
   3. If the pump does not turn on, the Ion+ switch/alarm may have to be replaced.
   4. If the pump does turn on, continue to the next step
3. Verify the range of the Ion+ switch/alarm. Your system should have been supplied with a 6” range switch.
