CFCs have been used in refrigerant as refrigerator and the insulation materials for many years. But it is now
known that these compounds which once seemed so ideal for use as cleaning agents and in refrigeration
systems, destroy the earth's ozone layer as a result, an international body decided on a total worldwide ban of
harmful CFCs by the end of 1995.
The service information is designed for experienced repair technicians only and is not designed for use by the general public.
It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to service a
