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 in 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 vital if brazing operations on the
pipework are to take place.
Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is
ventilation available.
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.
• Become familiar with the equipment and its operation.
• Isolate system electrically.
• Before attempting the procedure, ensure that:
o Mechanical handling equipment is available, if required, for handling
refrigerant cylinders.
o All personal protective equipment is available and being used correctly.
o The recovery process is always supervised by a competent person.
o Recovery equipment and cylinders conform to the appropriate standards.
• Pump down refrigerant system, if possible.
