2.1 Installation into the system
Use standard ISO centering rings only for installing ISO flanges!
The centering rings must fit well into the centering groove. Any clearance is prohibited. Too thick or
improperly centered rings can cause the plate to touch the centering ring if the plate is in open
position. This would damage the plate seal or interfere with the plate movement!
