purposes. For exposure to specific environments, check with chemical compatibility charts before
installing.
Fastening of the
threaded process
connection
Mounting torque for the thread may not exceed 40 Nm (metal thread)/ 20 Nm (plastic thread). Use a
open-end wrench. Do not fasten by turning the housing, for this will destroy the unit.
