Risk of freezing injury caused by refrigerant

When working on the air conditioning system, there is a risk of highly pressurised refrigerant escaping from the system. There is a risk of injury to the skin and parts of the body due to freezing.
  • Always wear safety gloves.
  • Always wear safety goggles.
  • Extract refrigerant, and open the refrigerant circuit immediately afterwards.
  • If more than 10 minutes passed since the refrigerant has been extracted, do not open the refrigerant circuit prior to extracting refrigerant anew. Due to re-evaporation, pressure will be built up in the refrigerant circuit.

Risk of damage to refrigerant lines

There is a risk of damage to the refrigerant lines due to rupture of the inner foil.
  • Never bend refrigerant lines to a radius less then 100 mm (r < 100 mm).
