MF Assembly Reassembly:
1. Assemble the MF assembly as follows (see Figure 7):
a. Make sure that the outer module o-rings have been replaced as described in the repair
procedures.
b. Insert the four small spacers in the four corner holes of the top and bottom MF module
head pieces at the inlet end of the MF assembly (see Figure 8).
c. Secure the two top piping adapters, shouldered spacers (see Figure 8 for proper
shouldered spacer orientation), and mounting brackets to the top rods using the nuts and
washers removed earlier. Tighten just snug tight until the bottom hardware is installed.
d. Secure the two bottom piping adapters and long spacers to the bottom rods using the
nuts and washers removed earlier. Tighten snug tight.

CAUTION
If the MF assembly is stood up vertically before it is lifted and installed on the
TWPS, the MF module tubes can compress down unless bracing is placed between
the MF assembly headers. It is recommended that the MF assembly headers be
braced before the assembly is moved.
2. Insert a brace, such as a 2x4 length of wood or metal, between the upper and lower MF assembly
headers at both ends of the assembly and secure with duct tape, rope, or some other temporary
means of keeping the brace in place (see Figure 5).
