Injury hazard!
Injury hazard!
- Note and follow safety instructions on containers,
- Avoid contact with refrigerant; wear safety goggles and hand protection,
- For additional information see: SAFETY INSTRUCTIONS FOR HANDLING TETRAFLUORETHANE REFRIGERANT R134A , or INSTRUCTIONS FOR HANDLING R1234YF REFRIGERANT and NOTES FOR REPAIR WORK ON AIR CONDITIONING .
CAUTION:
Overheating of the high-voltage system.
Risk of fire! Injury hazard!
Risk of fire! Injury hazard!
- If the low-temperature coolant circuit is empty, de-energize the high-voltage system.
- Drain the coolant only when the high-voltage system has been de-energized.
NOTE:
RISK OF DAMAGE
Careless handling of tools and sharp-edged components.
Scratches, surface damage.

- Wear safety goggles and protective gloves when disconnecting the refrigerant line.
- Close the refrigerant lines with seal plugs.
NOTE:
TECHNICAL INFORMATION
Immobilization period-long fill of coolant!
Do not reuse used coolant.
When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change the coolant. The cooling system must therefore be emptied and refilled.
In the case of other removal work involving the draining of part quantities of coolant, the coolant level must be topped up with new coolant.

- For full low-temperature coolant circuit only:
Open the lid (1) on the coolant expansion tank.
- Unclip the hose support (1) and set to one side.
- Loosen screws (2).
- Feed out refrigerant line (3) from the holder (4) and place to one side.
- Unlock and disconnect the coolant hoses (1).
- Catch and dispose of leakage coolant.
- Loosen screw (2).
- Push coolant hose (3) slightly to the side.
- Guide out the air conditioning condenser (4) toward the top and remove it.
