Detecting leaks in refrigerant circuit using leak detecting systemVAS 6196 or leak detecting systemVAS 6201.

Detecting leaks in refrigerant circuit using leak detecting system -VAS 6196- or leak detecting system -VAS 6201-.

Leak detecting system -VAS 6196-

Leak detecting system -VAS 6201-

Note!

Small leaks can be made visible, for example, by using a fluorescent leak detection additive -VAS 6196/1-.

Leak detection:

–	If the refrigerant circuit is completely empty, charge with about 100 grams of refrigerant.

–	Introduce leak detection additive -VAS 6196/1- into refrigerant circuit and use a UV lamp to examine refrigerant circuit.

Note!

The leak detection additive can be allowed to remain in the refrigerant circuit.
