5.3.3 Replace the exhaust plate or the exhaust cover
If you wish to exhaust the air non−ducted via a silencer, you
must use the narrow metal silencer type U−1/2−B with exhaust
plates (separate exhaust connections 3 and 5) for reasons of
space.
Proceed as follows:
1. Loosen the 4 fastening screws of the exhaust plate or the
6 fastening screws of the exhaust cover and remove them
from the basis component.
2. Check the seal between the basis component and the
exhaust plate for damage. Replace the seal if it is
damaged.
3. Make sure that the seal is seated correctly in the groove
in the pneumatic supply plate.
4. Fasten the exhaust plate only with the original screws.
Tighten the screws in diagonally opposite sequence at
first slightly and then with 2.2 Nm (±10 %).
5.3.4 Replace the manifold block, the pneumatic supply plate or the
right−hand end plate
