5. Install the new elements as follows (see Figure 4 and Figure 5):
a. Lubricate the inside of the vessel at the ends with a 50/50 glycerin/water mixture to ease
the insertion of the elements and to reduce the chance of scratching the vessel bore.
The mixture can be applied using a swab soaked in the mixture.
CAUTION
Be sure to install the thrust ring in the downstream end of the vessel. Failure to
observe this caution can result in serious damage.
b. Insert a clean thrust ring into the downstream end of the vessel. The thrust ring requires
no orientation; simply push it into the downstream end of the vessel.
c. Insert the end cap assembly, with the first element adapter, into the downstream end of
the vessel as follows:
1) Align the orientation mark that you put on the end cap assembly during removal
with the orientation mark that you put on the vessel.
CAUTION
Do not rotate the end cap assembly after inserting it into the vessel. Failure to
observe this caution may cause the end cap seal to bind or become detached.
2) Hold the end cap assembly square to the axis of the vessel and slide it straight
into the vessel until a slight resistance is felt.
3) Install the retaining ring into the groove in the vessel.
