Use care to prevent refrigerant from touching your skin or eyes. Liquid refrigerant, when exposed to air,
quickly evaporates and will freeze skin or eye tissue. Serious injury or blindness may result if you come
in contact with liquid refrigerant.
Refrigerant R-134a air conditioning systems should not be pressure tested or leak tested with com-
pressed air. Combustible mixtures of air and R-134a may form, resulting in a fire or explosion, which
could cause personnel injury or death.
DO NOT disconnect refrigerant lines from air conditioner compressor without first recovering refriger-
ant from system. Failure to recover system could cause uncontrolled release of high pressure refrigerant,
which can freeze skin and eye tissue causing serious injury or blindness.
If air conditioner compressor is being removed as an equipment condition for engine replacement, DO NOT
disconnect refrigerant hoses and lines. Perform ONLY the following four steps:
Disconnect compressor clutch electrical lead.
Cut tiedown straps securing refrigerant hoses.
Remove compressor mounting bolts.
Move compressor from mounting bracket to truck frame and secure in place to prevent damage.
