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. |
| 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. |
| 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). |
