Volkswagen Golf Service & Repair Manual: Charging devices that do not require a permit
| Charging devices that do not require a permit are mobile
charging devices into which pressurised gases are charged into
compressed gas containers for exclusive use of one company. |
| Some air conditioner service devices are charging devices
that do not require a permit. When these devices are used, the
refrigerant is charged not into locally mobile compressed gas
containers, but into a permanently installed charging cylinder
with a visible contents gauge and float switch. |
| When surplus refrigerant is transferred for one's own
requirements, it is recommended that a portable charging
cylinder with visible level gauge and pressure relief valve be
used. |
| Make sure to observe the corresponding technical rules (e.g.
TRGS 400, TRGS 402, TRGS 407, TRGS 510, TRBS 3145/TRGS 725) when
handling compressed gases and, in particular, when filling
compressed gases from one compressed gas container into another
one. |
