from the leak. Oxygen free nitrogen (OFN) shall then be purged
through the system both before and during the brazing process.
7. Removal and evacuation
When breaking into the refrigerant circuit to make repairs – or
for any other purpose – conventional procedures shall be used.
However, it is important that best practice is followed since
flammability is a consideration. The following procedure shall be
adhered to:
Remove refrigerant;
Purge the circuit with inert gas;
Evacuate;
Purge again with inert gas;
Open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct recovery
cylinders. The system shall be “flushed” with OFN to render the
unit safe. This process may need to be repeated several times.
Compressed air or oxygen shall not be used for this task.
Flushing shall be achieved by breaking the vacuum in the system
with OFN and continuing to fill until the working pressure is
achieved, then venting to atmosphere, and finally pulling down to a
vacuum. This process shall be repeated until no refrigerant is within
the system. When the final OFN charge is used, the system shall be
vented down to atmospheric pressure to enable work to take place.
This operation is absolutely vital if brazing operations on the
pipe-work are to take place.
