1. Place the seal on the connecting flange. To install
the displacer, insert the displacer in the vessel or
cage. Hold the wafer body above the connecting
flange. Connect the displacer as shown in figure 12,
locking the assembly with the cotter springs
provided. If a stem extension is used between the
displacer spud and the stem end piece, make sure
the nuts are tight at each end of the stem.
2. To position the wafer body on the connecting
flange, insert a stud, with nut, through the
connecting flange and one of the eyelets on the
wafer body, as shown in figure 11. Screw a second
nut onto the top of the stud to hold the wafer body in
place. This second nut may be removed after the top
flange is installed.
3. If you installed the displacer in step 1, go to
step 5, otherwise continue with step 4.
4. If installing a long or sectionalized displacer:
a. Remove the torque tube arm assembly and
displacer rod from the wafer body.
b. Insert the displacer through the wafer body
into the vessel or cage.

c. Reassemble the torque tube arm assembly
and displacer rod to the wafer body.
d. Connect the displacer as shown in figure 12,
locking the assembly with the cotter springs
provided. If a stem extension is used between the
displacer spud and the stem end piece, make
sure the nuts are tight at each end of the stem.
In the next step, if mounting the wafer
body on a displacer cage and a flange
adaptor is required, install the flange
adaptor instead of the blind flange.
5. Refer to figure 13. Place a second seal on top of
the wafer body. Place a blind flange on the wafer
body so that the holes in the blind flange align with
the holes in the connecting flange.
6. Refer to figure 14. Secure the wafer body
between the blind flange and connecting flange by
inserting the remaining studs and nuts. Tighten the
nuts just enough to hold the wafer body in place.
7. Remove the nut from the stud that was used in
step 2. Reinsert the stud so it passes through the
249W Level Sensor
