machine.
Note:
- Do not overfill cylinders to more than 80% volume liquid charge.
- Do not exceed the maximum working pressure of the cylinder, even temporarily.
5. When the cylinders have been filled correctly and the process completed, ensure that the
cylinders and the equipment are removed from the site promptly and that all isolation valves
on the equipment are closed off.
Note: Do not charge recovered refrigerant into another refrigerating system unless it
has been cleaned and checked.
What to do next:
Label the equipment stating that it has been decommissioned and emptied of refrigerant. Date and
sign the label. For appliances containing flammable refrigerants, ensure that there are labels on the
equipment stating that the equipment contains a flammable refrigerant.
