Warning! When replacing the fuel line, the line must be filled with new fuel. For diesel engines, filling with fuel must not take more than a maximum of 8 minutes. When the heater is started, the fuel fills in approximately 2 minutes. However as the control module only permits 3 failed start attempts, it will be insufficient to start the heater.

Warning! If the fuel pump (FP) is activated for an excessive amount of time, smoke may be generated or the heater may be damaged.

Caution! The button for ending activation does not function on the heater and fuel pump (FP). To switch off, select an alternative in the drop down menu that will disable the function.
