16. Place the bottom of the columns with two pads in the circular grooves in the lower
manifold. Ensure that they are in the grooves and not caught up on the edge.
17. Wipe the ends of the columns. These are the surfaces which seal against the
o-rings.
18. Place the upper manifold on top of the two columns. Ensure that the columns are in
the grooves. (Wiggle the columns sideways to ensure that the columns are trapped
in the grooves.)
19. Replace the nuts and lock-washers on the three tie rods BUT DO NOT TIGHTEN
THEM.
20. Push down hard in the center of the upper manifold with one hand and finger-tighten
the nuts until you feel a soft resistance.
21. With a wrench, tighten each nut in turn, 1/2 turn at a time. This will ensure that all the
nuts are tightened evenly. If the nuts are tightened unevenly, the column o-rings may
not seal and you may cause damage to the sealing surfaces.
22. Examine the fit of the columns in the manifold groove one more time.
23. Re-attach the 4-way valve bracket.
24. Replace the scrubber in the M701H chassis and tighten the four captive screws.
25. Reconnect the two pneumatic fittings and the valve power cord.
26. Plug in and turn on the M701H.
27. Using soap solution, check the dryer for leaks.
If no leaks are detected, the M701H is ready for operation.
