Safety Precautions When Working On A/C Systems

There is a risk of explosions from ignition sources.

There is a risk of explosions due to ignition sources near the A/C systems and refrigerant canisters. Leaking refrigerant can ignite and cause an explosion. Severe bodily injury or death caused by explosions possible.

• Do not bring any ignition sources near A/C systems and refrigerant canisters.

There is a risk of asphyxiation and poisoning from refrigerant.

Refrigerant fumes can cause problems ranging from a dry cough and nausea to asphyxiation and poisoning. Refrigerant is heavier than air and will collect in the lower areas.

• Do not inhale refrigerant fumes.
• Only work on the refrigerant circuit in well-ventilated areas.
• Store the refrigerant canister in a well vented room.
• Do not work in or near to lower areas.
• Switch on the exhaust extracting system.

There is a risk of frostbite from refrigerant.

When working on the A/C system, refrigerant under pressure can escape. 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.
