  Caution
Non-approved tools or materials such as leak sealing additives can cause damage or malfunctions in the system.
Only use tools and materials approved by the manufacturer.
The warranty is voided if non-approved tools or materials are used.
All components of the refrigerant circuit submitted for quality observation are always to be sealed (use original sealing caps of original part).
Replace damaged or leaking components of refrigerant circuit. Refer to → Chapter „Components, Replacing“.
To date, the original parts (compressor, reservoir, receiver/dryer, evaporator and condenser) have been filled with nitrogen gas. This charge is being gradually discontinued. There is little or no pressure equalization when removing the sealing plugs from the original part.
   
These o-rings seal off the connection points between individual components of the refrigerant circuit.
Only O-rings that are resistant to refrigerant r134a and refrigerant oil must be installed. Make sure they are original replacement parts.
