The refrigerant drums have a heavy metal cap. The cap protects the following components from damage:

    • The safety plug
        Ensure that you replace the cap after each use.

Whenever you carry a container of refrigerant in a vehicle, DO NOT carry the refrigerant in the passenger compartment. Refer to the manufacturer's guidelines for the following operations:

    • Storage
    • Transportation
    • Maximum temperature to where the container may be exposed

When you fill a small refrigerant drum from a large drum, do not fill the small drum completely. Ensure that you leave space for the liquid to expand.
