Fault Code:
| E01 | Startup Failure | *The diesel heater will display “E-01” if fuel has not arrived to the chamber of if you have run out of fuel. *Check the fuel tank whether is empty; *Check the fuel filter is not blocked and check if diesel is moving forward or not when the pump is pumping) •Inspect the fuel line from the tank all the way through to the unit to ensure that there is no blockage or leaks. Check that all joiners and miniclaps are correctly in position and not causing any blockage. |
| E02 | Lack of Fuel | *Check that there is enough fuel in the tank- add fuel |
| E03 | Supply Voltage Over Run | This usually indicates that there is not enough power for power to heat the glow plug. Check the battery output voltage is between in 9V and 16V for a 12V Heater and between 18V and 30V for 24V Heater |
| E04 | Outlet Sensor Faulty | This indicates a temperature sensor issue. This sensor is found on top of the aluminum body. Check that the sensor is plugged in to the main board properly and that is it secured firmly against the aluminum body. If this fails you may need to replace the sensor. |
| E05 | Inlet Sensor Faulty | Replace the ECU |
| E06 | Pulse Pump Faulty | Check the pump power is plugged in properly or that there is no damage to the electric wire to the pump. Whether, if its plugged in properly then you may need to replace the fuel pump or the electric wire to the pump. |
| E07 | Fan Fault | Check that nothing is blocking the fan, try and spin it with a screw driver. Check that the fan is plugged in to the main board correctly. if this fails you may need to replace the fan. |
| E08 | Ignition Unit Fault | Check that the glow plug is screwed into the aluminum casing properly and that it is plugged into the main board properly. If this fails then you may need to replace the glow plug. |
| E09 | Overheating | Check the air inlet and outlet on the heater unit to ensure that there is no blockage. |
| E010 | Overheat Sensor Fault | This indicates a temperature sensor issue. This sensor is found on top of the aluminum body. Check that the sensor is plugged in to the main board properly and that is it secured firmly against the aluminum body. If this fails you may need to replace the sensor. |
Monthly Checks and Maintenance:
The Aufocus Diesel heater should require very little maintenance.
● Simply start and run your heater on high for at least 15 minutes each month. This ensures everything keeps circulating and doesn’t give the diesel a chance to go off.
● Check that all ducts are attached securely at least once monthly and ensure that there is no obstruction at the ducts Inlet and outlet.
● After each road trip you should inspect the undercarriage of your vehicle to ensure that there is no damage and that nothing has moved. Note: Pay special attention to the exhaust and muffler as this gets extremely hot and there should be some clearance from the start of the exhaust all the way to the muffler. (Its shouldn’t be too close or touching anything that is not steel.
Conditions
● Storage Temperature: -55°C to +70°C
● Operating Temperature: -41°C to +50°C
● Only use Diesel Fuel to operate this unit
● Applicable Altitude: Civil<4,000m

Warnings:
- Do not place any combustible or flammable dangerous goods near the exhaust pipe.
- There should be no obstructions within 100 mm from the heater’s exhaust. The exhaust temperature is very high, any materials that cannot withstand high temperature may be damaged or may even potentially cause a fire.
- Do not use fuel other than diesel.
- If the heater is installed indoors, it is necessary to direct the exhaust fumes to the outside and ensure that there is no leakage. Failure to do so may result in the risk of exhaust gas poisoning or suffocation.
- When turning the heater off, ensure that the heater is allowed to run through a cool down cycle. Otherwise, the remaining diesel will not be burned out of the combustion chamber which can lead to carbon build up and excessive smoke from the exhaust.
- Do not modify the heater, use, repair or replace any components with non-Aufocus original parts.
