	Risk of poisoning  caused by inhaling overheated refrigerant vapors from an air conditioning system containing R134a. Risk of injury  to skin and eyes caused by contact with liquid R134a refrigerant and when working on pressurized parts	Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated rooms. Carry out repair work on the air conditioning system circuit only after the system has been evacuated.	AS83.00-Z-0006-01A
	Risk of fire  due to ignition of R1234yf refrigerant on hot components. Risk of poisoning  caused by inhaling overheated refrigerant vapors. Risk of injury  to skin and eyes caused by contact with escaped R1234yf refrigerant and when working on pressurized parts. Risk of explosion  due to formation of ignitable refrigerant/air mixtures	Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated rooms. Carry out repair work on the air conditioning system circuit only after the system has been evacuated.

	Compressor oils (specification 362.1)	Sealing rings must be replaced and moistened with compressor oil.	BB00.40-P-0362-01A
		Line on receiver/drier	*BA83.30-P-1002-01C
		Open end wrench attachment, 17_mm	Fig 1
3	Seal openings of refrigerant lines (4) with suitable stop plugs	The openings of the refrigerant lines (4) must be sealed. Otherwise, penetrating dirt and moisture will damage the air conditioning system.
		Record plug	Fig 2
4	Loosen mounting clamp (2)
5	Pull liquid reservoir (3) upwards out of the mounting clamp (2)	A new liquid reservoir (3) must be installed whenever the refrigerant circuit is opened.
6	Install in the reverse order
	Check
7	Evacuate air conditioning system, refill it, and then check the system to make sure that it functions correctly and does not leak		AR83.30-P-1760GW
