Step 5: Align Manifold and Make Manifold Connections

After the sample is loaded, you will need to align the manifold
as follows. The pressure manifold should only be connected
and disconnected from the cup assembly at the bottom of the
angled pipe connected to the cup as shown in Figure 8.20.
Please refer to the NOTE on page 93.
1. Prior to connecting the pressure manifold to the angled
pipe, slacken off to finger tight the compression connec-
tors on the manifold in order to easily align the manifold
with the pipe mounted on the cup. DO NOT USE EXCES-
SIVE FORCE TO POSITION THE PRESSURE MANI-
FOLD.
2. Finger-tighten ONLY the manifold to the angled pipe
mounted on the cup, using the connector indicated in
Figure 8.21.

nection or disconnection should be made at no other point while the pressure cell is
mounted on the rheometer.
NOTE: To disconnect the pressure cell from the manifold, ensure that both the cell and the
manifold are depressurized. Then disconnect the compression connector indicated in Figures
8.20 and 8.21.
WARNING: Before disconnecting the pressure cell from the manifold, ensure that neither
the cell nor the manifold is pressurized, and that both are cool enough to touch.

3. Once this fitting is finger tight, fully tighten all other
compression fittings as directed in the NOTE on
page 93.
4. Finally, fully tighten the angled pipe to the manifold
as directed in the NOTE on page 93.
CAUTION: To avoid putting excessive
force on the pressure cell, make sure that
connection or disconnection between the
pressure cell and the manifold is made at
the breakage point compression connec-
tor only (see Figures 8.20 and 8.21. Con-
