| Important instructions for working with the A/C service station |
| For operating the A/C service station (e.g. -VAS 6337-, currently available service positions, see → Catalogue of factory equipment) the following must be observed: |
| –
| The installed filters and dessicators must be replaced at the latest after reaching the operating time specified in the related operating instructions. |
| –
| If the A/C service station is also used for the flushing of the refrigerant circuit, the installed filters and dessicators must be replaced within short periods of time. |
| –
| Only fill in refrigerant oils which are approved for the refrigerant circuit specifically designed for vehicles. |
| –
| If there is any doubt about the composition of the refrigerant, the refrigerant which was suctioned out of the refrigerant circuit must not be re-used even after it has been cleaned in the A/C service station. |
| l
| In this case the A/C service station must be drained → Chapter, if necessary the system must be cleaned, the filters and the dessicators as well as the filled-in refrigerant oil must be replaced. |
| l
| Contaminated refrigerant can be returned to the supplier of the refrigerant, e.g. in the Federal Republic of Germany, in so-called recycling bottles for preparation or ecological disposal (different or additional directives may apply in certain countries). |
| The commercially available A/C service stations can be sub-divided into 2 groups: |
| t
| A/C service stations which clean drained refrigerant for re-use (so-called extraction and recycling stations) e.g. -VAS 6337-. |
| t
| A/C service stations which fill drained refrigerant into recycling bottles (in order to then treat it commercially), these systems are known as extraction systems. |
