| t
| The O-rings may only be used once, replace them every time they are removed. |
| t
| Lightly oil the O-rings with oil from the refrigerant circuit just before fitting. |
| t
| Ensure that the O-rings sit correctly into the corresponding tubes or grooves. |
| t
| Work in a clean area (even small impurities such as a hair for example can cause leaks). |
Note | t
| Only fit O-rings that are resistant to the refrigeration agent R134a and to the corresponding oil. These O-rings are easily identified by their colour to avoid possible confusion (currently “red”, “purple” or “violet”) → Spare parts catalogue. |
