Common Troubleshooting

Compressed Air Errors (F96, E03)

1

Verify air supply is connected

Ensure compressed air lines are connected to the device.

2

Check pressure is adequate

Typical required pressure: 6-8 bar. Verify actual pressure meets requirements.

3

Inspect air lines for leaks

Look for visible damage or audible leaks and repair as needed.

4

Ensure filter cleaning system functional

Confirm the filter cleaning/maintenance system is operating correctly.

Motor/Inverter Errors (F90, E00)

1

Check power supply stable

Verify voltage and supply stability to the device.

2

Verify no overload condition

Confirm the device isn't overloaded or operating beyond rated capacity.

3

Inspect electrical connections

Check wiring and connectors for looseness or damage.

4

Contact service for persistent issues

If the error persists after checks, contact KEMPER service.

Temperature Errors (E04)

1

Allow motor to cool down

Stop operation to let the motor reach safe temperature.

2

Reduce continuous operation time

Limit long continuous runs to avoid overheating.

3

Check ventilation around motor

Ensure adequate airflow and no obstructions to ventilation.

4

Reduce boost mode usage

Minimize use of high-power/boost modes that increase heat.

5

Contact service if recurring

If overheating returns, contact KEMPER service.

Airflow Errors (E02, E12)

1

Check for physical obstructions

Inspect ducts, intakes, and outlets for blockages.

2

Inspect filter condition

Look for clogged or damaged filters; replace if necessary.

3

Verify fan operation

Confirm the fan runs and operates at expected speed.

4

Replace filter if clogged

If cleaning doesn't restore flow, install a new filter.

Communication Errors (E07)

1

Check cable connections

Ensure communication cables are connected and undamaged.

2

Verify device powered properly

Confirm the device has stable power and is turned on.

3

Restart device

Power-cycle the device to attempt to clear transient communication faults.

4

Contact support if persists

If communication doesn't recover, contact KEMPER support.
