Refrigerant Dryer - Replace
Personal injury can result from contact with refrigerant.
Contact with refrigerant can cause frost bite. Keep face
and hands away to help prevent injury.
Protective goggles must always be worn when
refrigerant lines are opened, even if the gauges
indicate the system is empty of refrigerant.
Always use precaution when a fitting is removed.
Slowly loosen the fitting. If the system is still under
pressure, release it slowly in a well ventilated area.
Personal injury or death can result from inhaling
refrigerant through a lit cigarette.
Inhaling air conditioner refrigerant gas through a lit
cigarette or other smoking method or inhaling fumes
released from a flame contacting air conditioner
refrigerant gas, can cause bodily harm or death.
Do not smoke when servicing air conditioners or
wherever refrigerant gas may be present.
Use a certified recovery and recycling cart to properly
remove the refrigerant from the air conditioning
system.
