| Safety measures and rules of cleanliness when working on vehicles with liquefied petroleum gas system (LPG) |
DANGER! | l
| Service, installation and repair work on the liquefied petroleum gas system as well as their inspections must only be carried out by properly qualified personnel according to the relevant national legislation and standards! |
| l
| Service, installation and repair work on the liquefied petroleum gas system as well as their inspections must only be carried out by specialist garages with suitable safety elements according to the relevant national legislation and standards! |
| l
| Service facilities for repairs to the gas system must always be aboveground and never underground. A workshop pit should not be located in these premises. |
| l
| At least one source of natural ventilation must be assured at all times (also during the cold season). |
| When undertaking all work on the liquefied petroleum gas system, use the gas leakage detector for natural gas vehicles -VAS 6227-, which must be switched on constantly during this inspection, in order to continuously check for a possible LPG leakage. Position the gas leakage detector for natural gas vehicles -VAS 6227- as close as possible to the gas system, preferably under the vehicle!!! |
| l
| In auto repair shops, which do not have the suitable safety elements, vehicles with liquefied petroleum gas system (if this is not in contradiction with the legislation and standards of the relevant country) must only be driven in petrol mode and when the valve of the LPG reservoir is shut off → Chapter. |
| l
| At least one source of natural ventilation must be assured at all times (also during the cold season). |
| l
| Liquefied petroleum gas is highly flammable and forms ignitable mixtures with air. |
| l
| Because liquefied petroleum gas is heavier than air, it will always settle to the bottom. |
| l
| No sources of ignition must be located close to the liquefied petroleum gas system (as well as other spark- or flame-producing systems). |
| l
| The inhalation of liquefied petroleum gas can cause drowsiness and lung damage. In high concentrations, it results in a risk of asphyxia due to lack of oxygen. |
| l
| Liquefied petroleum gas is not „odourless“ because odour intensive substances are mixed with the liquefied petroleum gas. |
|
WARNING | l
| When working on the liquefied petroleum gas system, the battery earth strap must be disconnected. |
| l
| After the service, installation and repair work on the liquefied petroleum gas system, a gas system inspection must always be carried out → BookletOctavia II. |
| l
| Only system components of the same type and with the same design approval for the manufacture can be replaced. |
| l
| The components of the liquefied petroleum gas system, on which installation work should be carried out, must first of all be emptied → Chapter, or the gas must be carefully drained (outdoors, never close to buildings, reservoirs or a drainage system). |
| Ice accretion occurs when draining gas - do not touch - risk of accident. |
| l
| When undertaking all installation work, particularly in the engine compartment due to its cramped construction, please observe the following: |
| l
| Install the components of the liquefied petroleum gas system in such a way that the original cable guide of the liquefied petroleum gas system is re-established. |
| l
| Ensure that there is adequate free access to all moving or hot components, in order to avoid damage to the cables of the liquefied petroleum gas system. |
| l
| The cables on the liquefied petroleum gas system must not be bent. |
|
| For all tasks on the liquefied petroleum gas system, carefully pay attention to the following „rules of cleanliness“: |
| t
| Thoroughly clean the connection points and their surroundings before releasing. |
| t
| Place removed parts on a clean surface and cover. |
| t
| Do not use fluffy cloths! |
| t
| Carefully cover or close opened components if the repair is not completed immediately. |
| t
| Only install clean parts: First of all remove spare parts from their wrapping immediately before installing. Do not use any parts which have been stored unwrapped (e.g. in tool boxes etc.). |
| t
| When the system is opened: Avoid using compressed air. Avoid moving the vehicle. |
Caution | There is the risk of gas escaping! |
| System is under pressure: |
| t
| High pressure part up to approx. 20 bar (between filler neck, LPG reservoir and evaporator) |
| t
| Low pressure part approx. 2 bar (between evaporator and air inlet valves/gas distribution line (rail)). |
| t
| The gravity valve of the multi-function valve for the LPG reservoir is set to approx. 28 bar. After this pressure has been reached, excess gas is drained from underneath the vehicle. |
| Before opening the system lay cleaning cloths around the connection point. Reduce pressure by carefully releasing the connection point. |
| Wear protective spectacles and protective gloves. |
