If used: Insert the splinter shield and protective screen in
the high vacuum flange with the clamping lugs downward
(towards the pump).
➡
Bring the seal centric into the correct position.
➡
Connect the flanges via 2244 pieces of hexagon screws (M8)
with washers and nuts. The hexagon screws need to be
tightened revolving with a tightening torque of 22 ±2 Nm.
Control the torque afterwards, because of the sealing
material’s flowing a retightening of the screws may be
required.
