Handling Refrigerant
There is a risk of frostbite through refrigerant.
When working on the A/C system refrigerant can come out under pressure. Frostbite on the skin and other parts of the body is possible.
-- Wear protective gloves.
-- Wear protective eyewear.
-- Extract refrigerant and open the refrigerant circuit immediately.
-- If the refrigerant was extracted more than 10 minutes in the past and the refrigerant circuit was not opened, extract the refrigerant again. The refrigerant circuit pressure comes from evaporation.
Risk of destroying the refrigerant lines.
Destroying the refrigerant lines by ripping in the inner foil is possible.
-- Never bend the refrigerant lines to a radius smaller than r = 100 mm.
