| Arrangement of the exhaust systems in groups |
Note | t
| The air conditioning service and recycling equipments used in the vehicle workshops are extraction and filling systems (group „3“) which do not need a permission and must be only operated by knowledgeable personnel. The systems must be operated and maintained according to the manufacturer's documentation. |
| t
| The extraction and filling systems of the group „1“ and „2“ are used in the vehicle workshops. |
| The extraction and filling systems of the group „3“: |
| Portable extraction and filling systems to fill the pressure gas tanks which are firmly connected to the system. |
| The refrigerant or refrigerant/oil mixture is filled into pressure gas tanks which are permanently connected to the portable systems. In this case, according to the „pressure tank regulation“, the pressure gas tanks are equal to the pressure tanks. |
Note | There is no need for a permission nor the need to have the filling systems examined by the expert, because the gas is filled into pressure gas tanks which are equivalent to pressure tanks. (A permit, which is subject to the audit requirement, is in turn required for the system in order to fill up the pressure gas tanks with what is present in these pressure tanks and to pass them on to others). |
