Risk of explosion from welding or
soldering work on closed air
conditioning system. Risk of
poisoning. Inhaling overheated
refrigerant vapors may be toxic. 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 open
flames. Wear eye protection and protective
gloves. Work only in well ventilated areas.
Carry out repair work on the air
conditioning system circuit only after the
