Searching for leaks in refrigerant circuits using leak detector -V.A.G 1796-

Note!

t	Small leaks can be detected with, for example, an electronic leak detector.

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 100 grams of refrigerant.

Leak detection:

–	Prepare leak detector for operation according to its operating instructions.

–	Always hold probe tip under location of suspected leak.

If the rate of clicks rises or a howl occurs, depending on model, a leak has been found (see operating instructions for leak detector).
