Service Manual
NR-BY551MS, SS
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.
