Mounting position
For gas applications:
If there is a chance of condensation or if the gas stream can containsolid particles, mounting the product at the lowest point of a pipe
segment [4] is therefore not advisable.
▶ Mount the product in a location where condensate or particles
cannot accumulate inside the product [1,2,3,5].

21For liquid applications:
If there is a risk of expansion of dissolved gas in the product,mounting the product at the highest point of a pipe segment [2]is therefore not advisable.
▶ Mount the product in a location where gas bubbles cannot
accumulate inside the product [1,3,4,5].
