Vehicles and equipment variants, which are not listed in these installation instructions, have not been tested. However, installation according to these installation instructions may be possible. Depending on the version and the equipment variants of the vehicle, changes may be necessary relative to these "installation instructions" during installation and must be adjusted accordingly. However, where this is the case the stipulations in the "installation instructions" and "operating and maintenance instructions" for the Air Top 000 ST should be observed. The installation location of heater controls and the routing of the air ducting parts must be coordinated with the final customer prior to installation! WARNING! Original load-bearing components of the vehicle and/or component used for crash safety may not be modified for the hot air and recirculating air ducting! General Instructions Installation should be carried out according to the general, standard rules of technology. Unless specified otherwise, fasten hoses, lines and wiring harnesses to original vehicle lines and wiring harnesses using cable ties. Sharp edges should be fitted with edge protectors (split-open plastic hose). Spray unfinished body areas, e.g. drilled holes, with anti-corrosion wax (Tectyl 00K, Order No. 9).

Shut-down on fault Faults in individual heater unit components and malfunctions during the entire operation are recognized in the control unit. The heater unit is shut down (fault lock-out) if: - No or faulty start-up - Temperature sensor defective - Open or short circuit in overheating sensor - Overheating sensor mounted incorrectly - Break or short circuit in glow element - Fan motor overloaded, blocked, short circuit or open circuit - Fault in metering pump circuit or overheating protection (only during start-up phase) - Undervoltage < 0.5 V or overvoltage >6 V and longer than 0 sec. (on heater unit with V) - Undervoltage < V or overvoltage > V and longer than 0 sec. (on heater unit with V) - Control unit defective - Overheating - Flame detector (only on gasoline heater units) In case of overheating, the fuel feed is interrupted. A run-on is carried out as with manual shut-down. Following the run-on, the heater unit is in the fault lock-out mode. The overheating is indicated by the operation indicator flashing 0 times. Eliminate fault cause. For fault release, iefly switch the heater unit off and then on again (at least sec.). If serious malfunctions, such as overheating, or no start-up occurs increasingly frequently, then the heater unit is permanently locked (F or F) and can only be returned to operation following repairs by specially trained Webasto experts. Fault code output: Note: When equipped with a heater control, fault code output is carried out after a malfunction occurs by the switch-on check/fault code display flashing. After 5 rapid flashing pulses, the fault code output is carried out with a sequence of long flashing pulses in accordance with the numbers in the table below. When equipped with a combination timer, a fault output appears in the display of the digital timer after a fault occurs. When using the heater control, the fault number is indicated by the operating indicator lamp flashing: Display Fault Code F00 Control unit fault/incorrect data record/customer bus faulty F0 No start-up (after starting attempts)/no flame formation F0 Flame failure (repeated >) F0 Undervoltage or overvoltage F0 Premature flame detection F05 Flame detector (gasoline heater unit) open or short circuit F06 Open or short circuit in temperature sensor F07 Open or short circuit in metering pump F08 Open circuit, short circuit, overloading or blocking in fan motor F09 Break or short circuit in glow element F0 Overheating: As a result, continuous heater unit lock-out F Open or short circuit in overheating sensor F Heater unit lock-out F Continuous heater unit lock-out F Overheating sensor in incorrect position F5 Open circuit in setpoint encoder Legend for Fault Code Output 6
Final Work WARNING! Reassemble the disassembled components in reverse order. Check all hoses, hose, spring and Caillau clamps, as well as all electrical connections for firm seating. Secure all loose cables using cable ties. Spray the heater unit components with anti-corrosion wax (Tectyl 00K, Order No. 9). - Connect the battery - Set the digital timer. - Check the proper operation of the air heater, see the operating instructions/installation instructions. - Attach the "Switch off additional heater before refueling" sticker to the left-hand B-pillar. i Feel the drive Webasto AG Postfach 80-8 Stockdorf, Germany - Hotline +9- (0)805-978 Hotfax +9-(0)95-559-5 - http://www.webasto.de Printed in Germany 0/07Printed by: Steffen
