Danger! | Risk of explosion from welding or braizing work on closed air conditioning system. Risk of poisoning from inhaling overheated refrigerant vapors. Risk of injury from skin and eye contact with liquid refrigerant. | Do not carry out any welding work on the closed air conditioning system or in the surrounding area. No smoking or naked flames. Wear eye protection and protective gloves. Work only in well ventilated areas. Do not carry out repair work on the circuit of the air conditioning system unless the system is drained. | |
| Protect air conditioning circuit and components from moisture when carrying out repair work | All models fitted with air conditioning | |
| Notes for handling refrigerant R134a | All models with R134a refrigerant | |
1 | Attach suction, treatment and filling device to testing and filling valves (1, 2) | Observe suction, treatment and filling device operating instructions. | |
