Charging Systems Not Requiring A Permit

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

When performing work on refrigerant circuit or when handling refrigerant observe all generally applicable safety precautions and pressure container regulations.

Charging systems not requiring a permit are ones used for transferring compressed gases to mobile compressed-gas containers for internal use only.

Note:

Some service units are charging systems not requiring a permit. When working with such equipment, the refrigerant is not transferred to mobile compressed-gas containers, but rather into a permanently installed charging cylinder with visible level gauge and float switch.

Recommendation:

It is advisable to use a portable cylinder with visible level gauge and pressure relief valve for surplus refrigerant for internal use.

Attention must be paid to technical regulations for compressed gases (for example TRGS 400, TRGS 402, TRGS 407 TRGS 510 TRGS 725 / TRBS3145) when transferring compressed gases to other compressed-gas containers.
