NOTE
Take care not to scratch or damage the RO element during installation.
d. Load the first element into the upstream end of the vessel inserting the brine seal end of
the element last. Leave a few inches of the element sticking out of the vessel to allow
you to connect the next element to it.
NOTE
Apply only enough glycerin to the inter-connector O-ring to give the O-ring a
luster. Excessive lubricant could contaminate the elements.
e. Apply a small amount of glycerin to the inter-connector O-ring.
f. Assemble the inter-connector to the element that was just loaded into the vessel.
CAUTION
Support the second element as it is assembled to the inter-connector and the first
element. Do not allow the element weight to be supported by the inter-connector.
Failure to observe this caution can result in damage to the inter-connector or the
outer surface of the elements.
g. Line up the second element to be loaded and assemble the end without the brine seal to
the inter-connector that is already assembled on the first element.
