Installation
Leaks may occur due to the incorrect installation of CF flanges
Inadequate cleanliness when handling CF flanges and copper gaskets results in leaks and may
cause process damage.
► Always wear suitable gloves before touching or fitting any components.
► Fit seals only if dry and free of grease.
► Take care of damaged surfaces and cut edges.
► Replace the damaged components.
Required tools
● Hexagonal wrench (13 WAF)
● Calibrated torque wrench (tightening factor ≤ 1.6)

Connection of the hexagon head screw and through holes
1. For the connection of the turbopump, use only the approved mounting kits from Pfeiffer Vacuum.
2. If used: Insert the protective screen or splinter shield with clamping lugs downwards in the turbo-
3. Place the seal exactly in the hollow.
4. Connect the flange with the components of the mounting kit according to the figure.
5. Tighten the screw couplings all the way around.
6. Then check the torque, since flowing of the sealing material may make it necessary to re-tighten
