Risk of asphyxiation and poisoning from the refrigerant

Dry coughing and nausea due to suffocation and poisoning is possible due to refrigerant fumes.

-- Never breathe in refrigerant fumes.

-- Only work on the refrigerant circuit in well-ventilated areas and protect refrigerant cylinders.

-- Never perform procedures in and near basement staircases or other below ground areas.

-- Switch on the exhaust extracting system.

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.
