Build the Manifold
The manifold creates a hard connection between the reservoirs, gauge, intake, pressure controller and the vacuum source. It's much easier than it looks, so let's get going!

1. Place two passes of thread-sealing tape on each of the male threads from the parts list shown above. Wrap the tape clockwise around the fitting.
2. Attach the two brass pipes (1.5" long) to opposite sides of the brass cross fitting.
3. Attach a brass branch tee to each of the brass pipe union fittings. Note the direction of these fittings in relation to the brass cross as shown in the picture below. This is critical.
4. Attach the vacuum valve to the brass cross as shown below. Again, note the orientation of the handle on the valve. It must be aligned correctly with the rest of the manifold.
5. Attach the brass barb fitting (3/8" barb to 1/4 NPT-male) to the vacuum valve.
6. Attach the brass barb fitting (1/4" barb to 1/4 NPT-male) to the open end of the branch tee as shown in the picture below.
7. Attach the vacuum gauge to the manifold. Note that the face of the gauge points toward the brass barb fitting in step 6. The bubble in the gauge is normal.
8. Attach the brass elbow fitting (3/8" barb to 1/4 NPT-male) to the remaining open side on the branch tee.

The final assembly should appear as shown in the picture below.
