7.3. Installing coolant hoses
The clamps on the heat-exchanger connection pieces must be mounted between the bead and the hose shoulder.
Care must be taken to bleed the cooling system before the heater is taken
into service for the first time or after refilling with fresh coolant. Heater and
lines should be installed in such a way as to ensure static bleeding.
Malfunctions due to overheating may occur during operation if the heater
and lines have not been bled correctly.
Only spring band clamps approved by Webasto may be used for
the installation of the coolant hoses.
7.4. Installing circulation pump
The circulation pump must be installed in the coolant circuit on the pressure
side on the heater heat-exchanger inlet (see fig. 4).
Ensure the correct direction of flow of the circulation pump to the vehicle
coolant circuit. The installation position of the circulation pump must be
chosen so that the circulation pump is self-bleeding. It must be possible for
the air volume trapped in the circulation pump to automatically escape upward via the connection piece. Incorrect installation can result in malfunctions of the circulation pump.
See fig. 7: Installation positions of U4847 Econ circulation pump.
7.5. Checking
After the heater and all coolant-carrying components have been installed,
the entire coolant system must be checked for leaks with the system pressure specified by the vehicle manufacturer.

be provided with an effective cap to prevent fuel spillage. (Requirement
from 2001/56/EC, Appendix VII, Point 2.3.1. and ECE R122, Point 5.3.3.1.).
In the case of liquid fuel heaters, where a supply separate to that of the vehicle is provided, the type of fuel and its filler point must be clearly labelled.
(Requirement from 2001/56/EC, Appendix VII, Point 2.3.2. and ECE R122,
Point 5.3.3.2.).
8.1. Integration in engine supply or return line
The fuel integration is carried out either in the supply or return line, or with
a special fuel standpipe. On vehicles with a fuel pump, the fuel may not be
removed from the fuel supply line!
– If the vehicle has a check valve to the fuel tank, fuel may not be removed
from the return line.
– It must be ensured that no zero balance results in the vehicle system due
to the fuel removal.
– If fuel is removed from the swirl pot, it must be ensured that this pot is
not completely drained.
Proper installation is carried out as shown in fig. 9: Example of a fuel standpipe.

The fuel standpipe is installed in the fuel removal unit of the fuel tank.
See fig. 12.
Legend fig. 12:
31) Fuel standpipe
32) Fuel removal unit with hole
The installation surface of the fuel standpipe must be clean, flat and burrfree. When mounting the fuel standpipe in the fuel removal unit, ensure
careful routing of the standpipe. This may not impair the operation of the
parts of the fuel removal unit including the fuel gauge in any operating
mode. The length of the standpipe must be chosen so that a minimum distance of 10 mm over the fuel tank bottom or 20 mm over the bottom of
the fuel removal unit is ensured.
The specified securing measures of the vehicle manufacturer and the corresponding torques must be complied with.
Under no circumstances whatsoever may the fuel standpipe be
installed in the fuel tank body, but instead only in the fuel removal unit.
8.3. Fuel line
The fuel line is divided into the intake and the delivery line. As a result, the
intake line is a connection between the fuel tank and the metering pump,
while the delivery line produces the connection between the metering
pump and the heater.

8.3.1. Line installation
When installing the fuel line, it must be kept as short as possible.
The line must be installed protected against damage (e.g. stone impact) in
all areas.
The fuel line must always be routed in cool areas to prevent the formation
of bubbles due to warming.
High fuel temperatures can cause heater malfunctions. As a result, the line
may not be routed either past strong heat sources (e.g. exhaust gas) or near
stored heat zones.
In addition, the steepest possible routing of the fuel line must be ensured
from the fuel tank to the heater.
Fuel lines must be fastened in accordance with the latest technology so
that, for example, line sag is avoided.
Rub protection must be installed at sharp-edged transitions.
Do not route fuel lines through the vehicle interior.
8.3.2. Line design
Only lines approved by Webasto may be used as fuel lines.
8.3.3. Connecting two lines with a hose

13 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 vehicle 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
2
setting must be checked while operating the heater for the first
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 attachment during the trial run of the heater. If the heater suffers a fault during operation, the fault must be located and remedied.
14 Faults
To remedy a fault which has resulted in a fault lock-out, proceed according
to the workshop manual.
