| Discharging air conditioner service station |
Note | t
| If it is necessary to drain the air conditioner service station (e.g. due to extraction of contaminated refrigerant), all filters and dryers must always be renewed (do not remove filter and dryer from the air-tight packaging until immediately before installation to minimise moisture absorption). |
| t
| Refrigerant containers filled with contaminated used refrigerant are referred to as „Recycling containers“. |
| t
| Always evacuate recycling containers prior to initial filling with refrigerant (if there is air in a refrigerant container it is not to be filled with refrigerant). |
| t
| Do not mix various types of refrigerant (refrigerant mixtures cannot be recycled and must be disposed of). If there is any doubt about the composition of the contents of the container, the refrigerant recycling company must be informed. |
Caution | t
| When filling recycling containers (compressed-gas vessels), observe the applicable regulations, technical rules and laws. |
| t
| Recycling containers must never be overfilled. The gas cushion in overfilled recycling containers is not sufficient to absorb the liquid expansion caused by the influence of heat. There is a risk of rupturing. |
| t
| To ensure safety, make exclusive use of recycling containers fitted with a safety valve. |
| t
| Recycling containers must be weighed on calibrated scales during the filling process. The maximum permissible capacity is 75 % (charge factor 0.75) of the charge weight indicated on the recycling container (the possibility of refrigerant oil entering the recycling container along with the refrigerant cannot be ruled out). |
