Checking Initial Operation

Correct operation of the heater can be checked with
the Webasto Thermo Test PC Diagnosis.
Check the heater while in stable operation for ap-
proximately 20 minutes with the diagnostics monit-
oring the various functions.
13.4
Operating the Heater
NOTE
When filling the fuel line and purging air
only activate the fuel pump using the Ther-
moTest software. Using a different type of
switching device can damage the fuel
pump.
After the heater is completely installed:
Install the combustion air intake guard to prevent
damage to the combustion air fan.
Connect the heater to Webasto Thermo Test PC Dia-
gnostics.
Bleed the coolant circuit using Webasto Thermo Test
PC Diagnostics.
Check the coolant system for leaks at the system
pressure and / or temperature that is specified by the
vehicle manufacturer.
Filling the fuel lines:
Generally, the fuel lines are primed automatically on
initial start-up of the heater.
For the heater model with a return-style fuel system,
there is also an option to fill manually. Select the fuel
prime function in the Webasto Thermo Test PC Dia-
gnostics.
Prime the fuel line(s) until all of the air has been
purged from the fuel lines.
Ensure that the fuel filter has been bled. See Fuel Fil-
ter.
NOTE
The standard duration stored in the
Webasto Thermo Test software for fuel
prime is sufficient for most vehicle models
and heater applications.
If the lines cannot be successfully primed
using Webasto Thermo Test software, it
may be necessary to perform repeated
start-up attempts to prime the fuel line.
Once initial start-up is complete, fuel line
should be free of air bubbles.

Make sure that the coolant is less than 122 ºF
(50ºC).

Switch the heater ON via the control element
(refer to the control element operating instruc-
tions).

Check all connections for leaks.

CO2 settings are preset at the factory.

If the heater switches to fault lock-out condition
during operation, perform the troubleshooting
procedure. Refer to the service manual for more
information.
WARNING
WEBASTO HEATERS MUST BE SWITCHED
“OFF” WHEN RE-FUELING AT FILLING STA-
TIONS AND/OR WHILE LOADING OR UN-
LOADING FLAMMABLE MATERIALS FOR
TRANSPORT, TO PREVENT THE RISK OF EX-
PLOSION. PLEASE REVIEW OWNER’S
MANUAL FOR SAFETY AND USE INSTRUC-
TIONS.
NOTE
To maintain optimum heater condition, run
heater for 20 minutes monthly during the
off-season. Ensure any shut-off valves are
open before operating the coolant heater.
