c. Remove the 4 mounting brackets, 8 shouldered spacers, and 8 long spacers.
d. Label each bracket to indicate the location from which it was removed.
e. Remove the 4 piping adapters.
f. Remove the 8 short adapters from the module head pieces at the feed end of the

i. Using lint-free rags, clean the areas on both sides at the top and bottom of the module
where the o-rings mount.
