10. Decommissioning
• Before carrying out this procedure,
it is essential that the technician
is completely familiar with the
equipment and all its details.
• It is recommended good practice
that all refrigerants are recovered
safely.
• Prior to the task being carried
out, an oil and refrigerant sample
shall be taken in case analysis is
required prior to re-use of recovered
refrigerant.
• It is essential that electrical power
is available before the task is
commenced.
a) Become familiar with the
equipment and its operation.
b) Isolate system electrically.
c) Before attempting the procedure
ensure that:
• mechanical handling equipment is
available, if required, for handling
refrigerant cylinders;
• all personal protective equipment
is available and being used
correctly;
• the recovery process is
supervised at all times by a
competent person;
• recovery equipment and cylinders
conform to the appropriate
standards.
d) Pump down refrigerant system, if

e) If a vacuum is not possible, make
a manifold so that refrigerant can
be removed from various parts of
the system.
f) Make sure that cylinder is situated
on the scales before recovery

instructions.
h) Do not over fi ll cylinders. (No
