Initial start-up

The safety precautions in the operating and maintenance
instructions must be observed!
The operating and maintenance instructions must be read
through without fail before starting the heater.
After the heater has been installed, the coolant circuit and the fuel supply
system must be carefully bled, taking into account the directions of the ve-
hicle manufacturer.
It is recommended that the heater circulation pump be put into operation
with the component test function of the Webasto Thermo Test Diagnosis
to support bleeding.
Before the heater is operated for the first time, the coolant temperature
should be < 30 °C, as the heater does not go into combustion operation at
high engine temperatures.
Carry out first-time operation with the Webasto Thermo Test Diagnosis.
Prime the heater with fuel using the Webasto Thermo Test:
Press the fill line button and fill the lines until fuel is present at the heater.
Example:
43 sec. filling time with 300 cm line length, 7 Hz metering pump
frequency.
The CO setting must be checked while operating the heater for the first
2
time (for value range, see chapter 15, "Technical data").
Webasto recommends a setting of 10 vol. %.
All water and fuel connections must be checked for leaks and secure at-
tachment during the trial run of the heater. If the heater suffers a fault dur-
ing operation, the fault must be located and remedied.
