Searching for leaks in refrigerant circuits using leak detector -V.A.G 1796- |
Note Small leaks can be detected with, for example, an electronic leak detector. |
–
| Evacuate refrigerant circuit using an air conditioner service station → Chapter. |
Note t
| If a larger leak is detected during the evacuation process, determine cause and rectify as described → Chapter. |
t
| If during the evacuation process no leak is detected or a very small leak is detected that but cannot be located, proceed as follows → Chapter. |
t
| Refrigerant gas is quickly dispersed by air motion. Therefore drafts must be avoided during a search for leaks. |
t
| If the refrigerant circuit is completely empty, charge with about 10 % of refrigerant capacity (sticker R134a or vehicle-specific workshop manual). |
–
| Prepare leak detector for operation according to its operating instructions. |
–
| Always hold probe tip under location of suspected leak. |
