  • The distance of the diesel heater from the blockage

We assume you would connect the ducting hose to the air outlet, but some people don’t. In this case, please make sure there is no blockage before the heater. Leave at 10cm distance before the outlet. Otherwise, error E03 will show up.

  • The thermostat on the control panel

There is a thermostat on the control panel. It is used to measure the ambient temperature. Please make sure the panel is installed away from the heater outlet, which sends out hot air and will cause faulty data reading.

  • The exhaust pipe

Please make sure the exhaust pipe heads backward(heads to the trail), because you don’t want the exhaust goes back into the heater while you are driving


  • The diesel heater plugs

Please gently connect the plugs. Connecting with brute force could cause the plug pins displaced.

  • What to do on the first boot diesel heater

There might be air left in the fuel line during the installation, this could cause insufficient fuel supply, which leads to E19 in the end.

To kill this problem once for all, you may disconnect the fuel line from the heater first. Then press on/off button and release until you hear the fuel pump works(heater will not work at this point). When you see the fuel comes out from the line and ensure no air, you may press on/off again to turn off the pump.

Now reconnect the fuel line to the heater, and you may start the heater with no worries. 🙂
