General Safety Instructions:
Use care to prevent refrigerant from
touching your skin or eyes, because liquid
refrigerant, when exposed to air, quickly
evaporates and will freeze skin or eye
tissue. Serious injury or blindness could
result if you come in contact with liquid
Refrigerant R-134a air conditioning
systems should not be pressure tested or
leak tested with compressed air.
Combustible mixtures of air and R-134a
may form, resulting in a fire or explosion,
which could cause personal injury.
If the air conditioner compressor is being removed as an equipment condition for engine
replacement, DO NOT disconnect refrigerant hoses and fittings and only perform the
following four steps.
Disconnect compressor clutch electrical lead.
Cut cable ties securing refrigerant hoses.
Remove compressor mounting bolts.
Move compressor from mounting bracket to truck frame and secure in place
to prevent damage.
