Mounting

In case of horizontal mounting in adhesive products, the
surfaces of the tuning fork should be vertical in order to reduce
buildup on the tuning fork. On the screwed version you will find
a marking on the hexagon. With this, you can check the
position of the tuning fork when screwing it in. When the
hexagon touches the seal, the thread can be still turned by
approx. half a turn. This is sufficient to reach the recom-
mended installation position.
