| Pouring refrigerant into reservoir (charging cylinder or storage vessel) of air conditioner service station |
| l
| The work procedure must always be performed as described in the operating instructions of the air conditioner service station. |
| l
| A certain quantity of refrigerant is specified as charge for each air conditioning system. To ensure that neither too much nor too little refrigerant is added (either would reduce the cooling output), the charging cylinder has a scale indicating the weight for example. |
| l
| The volume of a refrigerant changes as a function of pressure. The scale must therefore be set according to the pressure in the charging cylinder. |
Note | Do not completely empty the charging cylinder or storage vessel, as the liquid column boundary layer cannot be traced in the indicator tube during filling (outside visible range). |
WARNING | Do not overfill. A completely filled charging cylinder or storage vessel will explode when the temperature rises. |
