8.
Screw the inlet cell cap into the cell body.
The cell cap should turn smoothly in the threads and not require any tools
for complete tightening. If you encounter resistance, carefully unscrew
the cap and start over. Make sure the threads are properly seated before
tightening completely.
9. Place an o-ring in each of the two o-ring grooves on both valve stems.
10.
Screw one valve stem into the inlet cell cap. Tighten the valve stem com
-
pletely.
To increase the life of the valve stem and cap, apply a thin layer of high-
temperature thread lubricant (#165-44-1) to the tip of the valve stem.
11.
Prepare the test fluid.
12.
Invert the cell body and carefully pour the sample into the cell. Leave
enough void space for thermal expansion (see chart below).
Be careful not to spill fluid on the o-ring shoulder inside the cell.
13. Place an o-ring in the cell and another on the cell cap.
14.
Place a circle of filter paper or ceramic disk on top of the cell o-ring. Gen
-
tly push the paper or disk downward so it contacts the o-ring without the
paper binding or pinching.
15.
Screw the outlet cap into the cell body.
16. Screw the other valve stem into the outlet cell cap and tighten it com
-
pletely.
17.
Invert the cell and place it in the heating jacket with the outlet (filter) side
pointed down. Rotate the cell in the heating jacket so that the pin in the
bottom of the heating well seats into the hole in the bottom of the test
cell. This will anchor the cell in the well and prevent it from rotating as the
valve stems are opened and closed.
