Proceed as follows:
1. Loosen and remove the tie rod screws.
2. Remove the right end plate from the tie rod.
3. Remove from the tie rod all manifold sub-bases and supply plates to the right of the pressure zone
separation to be installed.
4. Lubricate the VMPAC-TE… separators to be installed, using a lubricating grease that is safe for food
products in accordance with the manufacturer's declaration (e.g. class NSF H1).
5. Insert a separator into each channel (1), (3) or (5) that you wish to separate (
è
Fig. 2.6). The valve
mounted to the right of the separator belongs to the next (following to the right) pressure zone,
while the valve mounted on the manifold sub-base with separator still belongs to the pressure zone
to the left of the separators.

6. Check the seals of the manifold sub-bases and replace if damaged.
7. Push the manifold sub-bases onto the tie rod (

8. Place the right end plate onto the tie rod.
9. Put a sealing ring onto each tie rod screw.
10.Insert the tie rod screws into the right end plates.
11.Then tighten the screws (A/F 6) in the sequence 1 … 5 (

– 1st step: hand-tight
– 2nd step: 2.0 Nm ( ± 10 %)
– 3rd step: 3.5 Nm ( ± 10 %)
12.Then check the torque on all five screws, as the torque on the screws can change during the tighten
ing process.
