Vehicle Damage Warnings




Refrigerant System

During all work on the air-conditioning system which necessitates opening the refrigerant system, the system contents must first be disposed of correctly. When doing so, follow the safety regulations.

Dirt and moisture must be kept out of the air-conditioning system's pipe system. Thorough cleanliness must therefore be ensured during all work. System components must never be cleaned on the inside with hot steam. Use only nitrogen for cleaning purposes.

When replacing a component, all openings must be closed off with suitable plugs.
