DANGER Risk of explosion  caused by welding or soldering work on closed air conditioning system. Risk of poisoning  caused by inhaling overheated refrigerant vapors. Risk of injury  to skin and eyes caused by contact with liquid refrigerant. 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 areas. Carry out repair work on the air conditioning system circuit only after the system has been drained. AS83.00-Z-0001-01A
