M1207026 9-9
9.5 Service the pipeline inlet manifold components
The pipeline inlet filter and the inlet check valve can be replaced
without removing the pipeline manifold from the machine.
9.5.1 Replace
pipeline inlet filter
1. Remove the pipeline inlet fitting.
2. Pull the pipeline inlet filter out of the fitting. The o-ring should
come out with the filter.
3. Install the new pipeline inlet filter in the pipeline inlet fitting. The
new filter comes with an o-ring.
9.5.2 Replace
pipeline inlet check
valve
1. Remove the rear upper panel (Section 9.2).
2. Remove the pipeline inlet fitting.
3. The Air and O
2
pipeline manifolds include a drive gas connection
at the back of the manifold. Remove the drive gas tube or plug to
access the check valve.
4. From the back of the pipeline manifold, use a thin tool to push out
the check valve.
(For an N
2
O manifold, you will have to carefully apply pressure at
the outlet of the manifold — with a syringe for example — to
gently force the check valve out of the manifold).
5. Push the new check valve into the opening, using the same thin
tool. The new check valve includes an o-ring — orient it toward
the pipeline inlet. Note: Make sure to push the new check valve
all the way back into the opening until it bottoms out on the
shoulder.
6. Install the pipeline inlet fitting.
