Prior to recharging the system, it shall be
pressure-tested with the appropriate purging gas.
The system shall be leak-tested on completion
of charging but prior to commissioning. A follow
up leak test shall be carried out prior to leaving
the site.
2.10 Decommissioning
Before carrying out this procedure, it is essential
that the technician is completely familiar with the
equipment and all its detail. 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 reclaimed
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 possible.
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 takes place.
g) Start the recovery machine and operate in
accordance with manufacturer’s instructions.
h) Do not overfill cylinders. (No more than 80 %
volume liquid charge).
i) Do not exceed the maximum working pressure
of the cylinder, even temporarily.
j) When the cylinders have been filled correctly
and the process completed, make sure that the
cylinders and the equipment are removed from
site promptly and all isolation valves on the
equipment are closed off.
k) Recovered refrigerant shall not be charged into
another refrigeration system unless it has been
cleaned and checked.
2.11 Labelling
Equipment shall be labelled stating that it
has been de-commissioned and emptied
of refrigerant. The label shall be dated and
signed. For appliances containing flammable
refrigerants, ensure that there are labels on
the equipment stating the equipment contains
flammable refrigerant.
2.12 Recovery
When removing refrigerant from a system,
either for servicing or decommissioning, it is
recommended good practice that all refrigerants
are removed safely.
When transferring refrigerant into cylinders,
ensure that only appropriate refrigerant recovery
cylinders are employed. Ensure that the correct
number of cylinders for holding the total system
charge are available. All cylinders to be used
are designated for the recovered refrigerant and
labelled for that refrigerant (i.e. special cylinders
for the recovery of refrigerant). Cylinders shall
be complete with pressure-relief valve and
