1. Check that all the sealing surfaces are clean. 

2. Brush the threads of the bolts clean, using a steel 

wire brush. 

3. Attach gaskets to the plates or check that all the 

gaskets are properly attached. 

 

Note!

 If the gasket is wrongly positioned, it will show 

by the fact that it rises out of the gasket groove or 
that it is positioned outside of the groove. 

 
4.  Place  the  plastic tubes  in  the  right  order  (marked 

plastic  end  tubes  are  assembled  last  and  mate 
with front tubes). Lock with nuts. 

 
5.  Insert  the  plates  with  the  herring  bone  pattern 

positioned  in  alternate  directions  and  with  the 
gaskets turned towards the frame plate. 

 

Note!

  Check and make sure all the plates are in the 

correct order and aligned.

6. Place the pressure plate on the plate package. 

7.  Lubricate  the  bolt  threads  with  a  thin  layer  of 

grease, e.g. Gleitmo 800 or equivalent. 

8.  Tighten  the  tightening  bolts  alternatively  and 

diagonally  in  the  sequence  shown  (1-2-3-4)  to 
1.10A. Be careful so that the frame plate and the 
pressure  plate  are  always  in  parallel,  check  and 
make  sure  the  measurements  between  them  at 
positions of bolts are 1.10xA during tightening. 

Note!

    Check  again and make  sure  all the  plates  are 

aligned.
