operation is absolutely vital if brazing operations are to take place on pipes.
Ensure that the vacuum pump outlet is not near any source of ignition and that
ventilation is available.
8. Loading procedure
In addition to conventional loading procedures, the following requirements must be
followed.
Ensure that no contamination of different refrigerants occurs when using the loading
equipment. Hoses or lines should be kept as short as possible to minimise the amount
of refrigerant contained in them.
Cylinders must be kept in an upright position.
Ensure that the refrigeration system is grounded before loading the system with
refrigerant.
Tag the system when charging is complete (if not already).
Extreme care must be taken to avoid overfilling the cooling system. 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
