repair procedure
1. Use compressed air to blow any loose particulates and dust from the manifold and
components prior to loosening fasteners. Use caution around small parts and
elastomers such as o-rings and diaphragms.
2. Obtain alcohol prep pads or similar damp cleaning wipes before removing
components. Do not use materials that will lose fibers or leave a residue on
components.
3. Completely remove all fasteners and place in a temporary container before moving
the component.
4. Carefully lift the component straight up and away from the manifold. Check to make
sure all necessary o-rings and gaskets are present. Store components in a
temporary container and not on the workspace tabletop.
5. If the component is going to be re-installed, place it on the side or back on a clean
surface to protect the mating surface.
6. Using an alcohol prep pad, damp wipe clean the manifold surface by starting at the
opening and wiping away from it. This will reduce the risk of loose material dropping
into the manifold.
7. Carefully inspect the opening in the manifold. If there is any visual sign of
contamination or discoloration, the manifold and any upstream components must
be replaced.
8. If the component removed is to be reinstalled, clean it in a similar manner by wiping
from any gas stream access points toward the outside edge.
9. Carefully inspect the component and seal. If there is any sign of contamination,
knicks, small tears, or discoloration, the component and or seal must be replaced.
10.Carefully set the component back on the manifold directly over and aligned with the
attachments and avoid sliding the component once it is in contact with the manifold.
11.Reinstall the fasteners and torque it to the required specification as listed.
