A/C refrigerant system, notes
Safety measures
The subassemblies and lines of the air
conditioner are filled with Tetrafluoroethane also
known as refrigerant R-134a.
Refrigerant R-134a replaces refrigerant R-12.
R-134a and R-12 systems are similar in design
but there are very important differences in the
refrigerant, lubricating oils, service equipment
and A/C system components.
A label on the lock carrier in the engine
compartment indicates the refrigerant type and
capacity.
WARNING!
Always use an Underwriter's Laboratory (UL)
approved refrigerant recovery/
recycling/recharging unit such as Kent-
4
Moore ACR , or equivalent, whenever
discharging an R-134a A/C system.
As of January 1, 1992 any person who
services a motor vehicle air conditioner
MUST, by law, be properly trained and
certified and use approve refrigerant
recycling equipment. Technicians must
complete an EPA approved recycling course
to be certified.
State and Provincial governments may have
additional requirements regarding air
conditioning servicing. Always comply with
local laws.
