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.
F. Ensure that the cylinder is positioned on the scale before recovery takes place.
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).
I. Do not exceed the maximum working pressure of the cylinder, even temporarily.
J. When the cylinders have been correctly filled and the process is complete, ensure
that 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 cylinders are used. Ensure that the correct number of cylinders is available
to support the total load of the system. All cylinders to be used are designated for the
refrigerant recovered and labelled for that refrigerant (i.e., special refrigerant-recovery
cylinders). Cylinders must be completed with pressure-relief valves and associated
shut-off valves in good working order. Empty recovery cylinders are evacuated and, if
possible, cooled before recovery takes place.
Recovery equipment must be in good working order with a set of instructions
