Please note
The use of leak detection spray can result in
faulty operation.
Leak detection spray must not come into
contact with electrical contacts.
Note
Only use suitable and approved leak detection
agents (EN 14291) and devices for the tightness
test. Leak detection agents with unsuitable constit-
uents (e.g. nitrides, sulphides) can cause material
damage.
Remove residues of the leak detection agent after
testing.
