Before reloading, the system must be pressure-tested with oxygen-free nitrogen. The
system shall be leak-tested upon completion of loading, but prior to commissioning. A
subsequent leakage test must be carried out before leaving the site.
9. Commissioning
Before performing this procedure, it is essential that the technician is thoroughly familiar
with the equipment and all its details. It is recommended good practice that all refrigerants
are safely recovered. Before the task is carried out, a sample of oil and refrigerant should be
taken in case an analysis is required before the recovered coolant is reused. It is essential for
there to be power before starting with the task.
A. It is important to get familiar with the equipment and its operation.
B. Electrically isolate the system.
C. Before attempting the procedure, ensure that
-
the mechanical-handling equipment is available, if required, for the handling of
refrigerant cylinders;
-
all personal protective equipment is available and correctly used;
-
the recovery process is supervised at all times by a competent person;
-
cylinders and recovery equipment conform to appropriate standards.
D. Pump the cooling system, if possible.
E. If vacuum is not possible, make a manifold so that refrigerant can be removed from
various parts of the system.
Ensure that the cylinder is positioned on the scale before recovery takes place.
F.
G. Switch on the recovery machine and operate it according to the manufacturer's
instructions.
H. Do not overfill cylinders (no more than 80% of the liquid charge by volume).
Do not exceed the maximum working pressure of the cylinder, even temporarily.
I.
When the cylinders have been correctly filled and the process is complete, ensure that
J.
the cylinders and equipment are promptly removed from the site and that all equipment
isolation valves are closed.
K. Recovered refrigerant must not be charged to another refrigeration system, unless
cleaned and checked.
10. Labelling
The equipment must be labelled stating that it has been taken out of service and drained
of refrigerant. The labelling must be dated and signed. Ensure that there are labels on the
equipment stating that the equipment contains flammable refrigerant.
11. Recovery
-
When refrigerant is removed from a system, either for service or decommissioning, it is
recommended good practice that all refrigerants are removed safely.
-
When transferring refrigerant to cylinders, ensure that only suitable refrigerant-recovery
