Webasto Air Top 3500 and Air Top 5000 Heater Service Manual

The Webasto Air Top 3500 and Air Top 5000 are auxiliary air heaters. On a crane or heavy vehicle they warm the cab so the operator isn't running the engine just for heat. When one quits, the person reaching for the service manual is usually the tech who has to find the fault, fix it in the shop and get the unit working again without sending it out.

What this manual helps you do

• Diagnose a heater that won't start or shuts down, using the troubleshooting section.
• Check operation step by step with the functional checkouts.
• Trace wiring problems with the circuit diagrams and the electrical connections.
• Replace worn or failed components by following the repair procedures.
• Verify the unit against the technical data before it goes back in the machine.

Who this is for

A crane service technician, rental fleet mechanic or independent repair shop that maintains Webasto Air Top heaters in-house. It also suits a dealer technician or plant maintenance person who inherited a machine with no paperwork.
