RECLAMATION - Filling Procedures

1. Visually inspect the container to be filled. Strictly follow all DOT requirements for inspection of
1. refrigerant containers. For all cylinders, leak test by a vacuum gauge. NRI is not responsible for
1. refrigerant recovered into a leaking cylinder.

2. Place the container on a scale. Note empty weight of container to determine Maximum Gross
1. Weight.

3. Connect transfer hoses to the container. Make certain hoses are leak free. If at all possible, change
1. hoses when recovering different types of refrigerants to avoid contamination by unintentionally mixing
1. refrigerants.

4. Open container outlets and begin the transfer process following manufacturer's instructions for the
1. recovery unit. DO NOT LEAVE THE CONTAINER UNATTENDED. Watch the scale closely. DO NOT
1.
OVERFILL. Do not exceed the gross weight limit. Do not fill more than 80% by volume. It is illegal to
1. transport an overfilled cylinder.

5. When the scale reaches the gross weight limit, stop the transfer process. Tightly close all valves and
1. other outlets.

6. Disconnect the transfer hose. AVOID CONTACT WITH LIQUID REFRIGERANT/OIL MIXTURES
1. (see Material Safety Data Sheet for specific refrigerant). Immediately replace all valve outlet caps and
1. other container closures.

7. Weigh the container. Write the weight on all appropriate forms and on the container tag or label.

8. Completely fill out the container tag or label. Be sure the tag or label indicates the correct refrigerant
1. in the container. It is illegal to transport a container without correctly identifying the contents
1. (Including empty cylinders).

9. There will be a cylinder cleaning charge for cylinders returned less than 50% full. Check off the "For
1. Cleaning Only" box on the hang tag. There will be a container handling fee for overfilled containers as
1. determined by NRI's Cylinder Weight Chart.
