| Drain A/C service station |
Note | t
| If it is necessary to drain the A/C service station (e.g. because contaminated refrigerant was drained off), always replace all the filters and dessicators (shortly before installing, remove the filters and dessicators from the airtight sealed transport packaging in order to keep the increase of humidity as low as possible). |
| t
| Refrigerant bottles which are filled with contaminated and used refrigerant are known under the designation „recycling bottles“. |
| t
| Always evacuate recycling bottles before filling with refrigerant for the first time (refrigerant bottles, in which there is air, must not be filled with refrigerant). |
| t
| Different types of refrigerants must not be mixed with each other (refrigerant mixtures can no longer be recycled yet they must be disposed of). If there is any doubt about the composition of the bottle content, the refrigerant operator must be advised. |
Caution | t
| When filling up recycling bottles (pressure gas tanks) the existing regulations, technical rules and laws must be observed. |
| t
| In any case, avoid overfilling the recycling bottles (overfilled recycling bottles have a too low gas blanket in order to absorb the liquid expansion caused by the effect of the heat). There is a risk of bursting. |
| t
| For your own safety, only use recycling bottles with a safety valve fitted. |
| t
| Recycling bottles must be weighed on a calibrated scale when filling up. The maximum authorised filling capacity is 75% (filling factor 0.75) of the filling weight given on the recycling bottle (it cannot be excluded that besides the refrigerant, refrigerant oil is also filled into the recycling bottle). |
