Decommissioning
Before decommissioning, it is essential that the technician become completely familiar with all of the
equipment in detail. It is a recommended good practice that all refrigerants be recovered safely.
Before decommissioning, an oil and refrigerant sample should 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.
Before decommissioning procedure ensure that:
1) You are familiar with the equipment and its operation.
2) The system has been isolated electrically.
3) Mechanical handling equipment is available, if required, for handling refrigerant cylinders.
4) All personal protective equipment is available and being used correctly.
5) The recovery process is supervised at all times by a competent person.
6) Recovery equipment and cylinders conform to the appropriate standards.
Decommissioning procedure:
1) Pump down refrigerant system, if possible.
2) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts
of the system.
3) Make sure that cylinder is situated on the scales before recovery takes place.
4) Start the recovery machine and operate in accordance with manufacturer's instructions.
5) Do not overfill cylinders. No more than 80% volume liquid charge.
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges
or any other adverse environmental effects. The check should also take into account the effects of
ageing or continual vibration from sources such as compressors or fans.
In addition to conventional charging procedures, the following parameters must be followed:
1) Ensure refrigerant contamination does not occur when charging equipment.
2) Hoses or lines should be as short as possible to minimize the refrigerant contained in them.
3) Cylinders must be kept upright.
4) Take extreme care to avoid refrigerant overfill.
5) Label the system when charging is complete (if not already).
6) Extreme care shall be taken not to overfill the refrigeration system.
7) Prior to recharging the system pressure test with OFN. The system must be leak tested when
charging is complete and prior to commissioning. A follow up leak test must be carried out before
leaving the site.
