ACTIVATING COMPONENTS
This function allows a number of components to be activated so that their functions can be checked. The following components can be activated
COMBUSTION FAN

| WARNING | Filling the fuel line should only be used when replacing the fuel line. If fuel is filled for an excessive amount of time, smoke may be generated or the heater may be damaged. However, it is necessary to fill the fuel line after it has been replaced. The combustion preheater module (CPM) only allows 10 start attempts for the heater. After replacing the fuel line, fill a diesel engine for a maximum of 8 minutes. After replacing the fuel line, fill a gasoline engine for a maximum of 8-10 minutes. |
