Volkswagen Polo Service & Repair Manual: Charging Systems not Requiring a Permit

At this time, A/C service units for extracting, cleaning and filling refrigerant for motor vehicle A/C systems are available from various manufacturers.
Charging systems not requiring a permit are ones used for transferring compressed gases to mobile compressed-gas vessels for internal use only.
Note:
Some A/C service units are charging systems not requiring a permit. When working with such equipment, the refrigerant is not transferred to mobile compressed-gas vessels, 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.
Observe the different technical regulations for handling and filling compressed gases in other compressed-gas vessels (for example RGS 400, TRGS 402, TRGS 407, TRGS 510, TRBS 3145 / TRGS 725).
