tested with OFN. 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.
13. 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
refrigerant cylinders;
protective equipment is available and

process is supervised at all times by a
competent person; Recovery equipment
and cylinders conform to the appropriate
standards.
d) Pump down
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 instructions.
h) Do not overfill cylinders. (No more than
80% volume liquid charge).
i) Do not exceed the maximum working
pressure of
temporarily.
j) When the cylinders have been filled
correctly and the process completed,
make sure that the cylinders and the
equipment are

14. Labelling
Equipment shall be labelled stating that it
has been de-commissioned and emptied
of refrigerant. The label shall be dated
and signed. Ensure that there are labels
on the equipment stating the equipment
contains flammable refrigerant.

appropriate
cylinders are employed. Ensure that the
correct number of cylinders for holding
the total system charge is 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 associated shut-off valves in
good working order. Empty recovery
cylinders are evacuated and, if possible,
cooled before recovery occurs.

The recovery equipment shall be in good
working order with a set of instructions
concerning the equipment that is at hand
and shall be suitable for the recovery of
flammable refrigerants. If in doubt, the
manufacturer should be consulted. In
addition, a set of calibrated weighing
scales shall be available and in good
working order. Hoses shall be complete
with leak-free disconnect couplings and
