5. Load the first element into the upstream end
of the vessel. Leave a few inches of the
element projecting from the vessel to facilitate
interconnection to the next element.
6. Apply a light film of a non-petroleum based
lubricant to the interconnector O-ring. (The
amount of lubricant should be just enough to
give a lustre to the O-ring. Excess lubricant
must be removed to prevent possibility of
element contamination).
7. Assemble the interconnector to the loaded
element.
8. Line up the next element to be loaded and
assemble it to the interconnector already
assembled on the first element.
9. Push both elements into the vessel until a few
inches are projecting from the vessel. Repeat
loading process
installed.
CAUTION
Maintain element alignment carefully
during assembly procedure. Do not allow
element weight to be supported by
interconnector.
Mis-alignment can result in damage to
interconnectors or permeate tubes or to
element outer surface.
Take care to avoid pushing elements too
far as it can be difficult to push the stack in
a reverse direction.

Step 4. Install Element Interface Hardware
1. Assemble adapter to element permeate
tube at each end of vessel.
(Connect the central (permeate) tube of
the membrane element stack, with an
adapter on each end, to the permeate port
in the head at both ends of vessel.
Pressurizing vessel without both adapters
installed could result in explosive head
failure)
