Safety Precautions When Working On A/C Systems

There is a risk of getting frostbite from the refrigerant.

Refrigerant can come out under pressure when working on the A/C system. Frostbite on the skin and other parts of the body is possible.

-- Wear safety gloves.

-- Wear protective eyewear.

-- Evacuate or drain refrigerant and open the refrigerant circuit immediately.

-- If more than 10 minutes elapse after extracting or draining the refrigerant and the refrigerant circuit has not been opened, extract or drain the refrigerant again. Pressure develops in the refrigerant circuit due to evaporation.

There is risk of destroying the refrigerant lines.

The refrigerant lines can be destroyed by ripping through the inner foil.

-- Never bend the refrigerant lines to a radius smaller than r = 100 mm.
