Check that all the sealing surfaces are

Brush the threads of the bolts clean, using
a steel wire brush. Lubricate the threads
with a thin layer of grease, e.g. Gleitmo
800 or equivalent.
Attach gaskets to the plates or check that
all the gaskets are properly attached.
Insert the plates with the herring bone pat-
tern positioned in alternate directions and
with the gaskets turned towards the frame
plate.
Press the plate assembly together. Tight-
ening is done in two steps, see figures be-

the pressure plate are always in parallel.
Tighten the two diagonal pair of bolts alter-
nately until the plate package measures

After that bolts are tightened alternately
and diagonally, as shown in the figure be-
low.

If the gasket is wrongly positioned, it will
