    <p>Looking at the photos I took, I did not see any labels on the
      valves- something which should probably be corrected at some
      point. functionally, there is no difference between connection at
      MV4 and MV1, although you should be able to physically "walk
      down"  the P&I diagram- it should be an accurate map.<br>
