4.6.2 Applying sealing medium to the rotary shaft seal during assembly
The area within the shaft sealing unit (D) and (E) must be filled with a sealing medium *
resistant to aggressive media prior to assembling or after cleaning the dispenser.
For this purpose, using your finger, apply sufficient sealing medium to the surface (H) of
the rotary shaft seal (20) pressed into the spacer (19). In this way sufficient sealing
medium is applied to the shaft sealing unit (E).
Wipe off excess sealing medium after assembly of the shaft sealing units.
* We recommend OKS 469.
