Start-Up
-
The controllers should be located in a clean dry atmosphere relatively free from shock and vibration.
-
Leave sufficient room for access to the electrical components and install in a manner that permits easy removal if
the instrument requires cleaning.
-
Contamination or corrosion may occur when used with reactive gas as a result of plumbing leaks or improper
purging.
-
These controllers should only be used with inert gases like Nitrogen and Argon.
