EVACUATION
WARNING
Use care to prevent refrigerant from touching skin or eyes. Liquid refrigerant, when
exposed to air, quickly evaporates and will freeze skin or eye tissues. Failure to comply
may result in injury or death to personnel.
Do not attempt to apply compressed air to the internal components of refrigerant R-134a
air conditioning systems for pressure or leak test. Combustible mixtures of air and R-134a
may form resulting in a fire or explosion. Failure to comply may result in injury or death
to personnel.
Personnel with a history of cardiac rhythm abnormalities should be made aware of
potential aggravation as a result of exposure to refrigerant. Failure to comply may result
in injury or death to personnel.
CAUTION
Use of a refrigerant indentifier is required to ensure that refrigerant to be recovered is
R-134a. Failure to comply may result in damage to the equipment.
Air conditioner receiver/dryer must be replaced each time air conditioner system is
opened. Failure to comply may result in damage to the equipment.
