1. Remove the membrane bag containing the membrane from the shipping tube.
2. Cut the bag open as close as possible to the seal at the end of the bag, so that
the bag may be re-used if necessary.
3. Remove the membrane from the bag and remove the foam protectors from
each end of the membrane.
4. Remove the parts from the parts container (if included) and inspect. Make sure
that all parts are clean and free from dirt. Examine the O-rings, brine seal, and
permeate tube for nicks or cuts. Replace the O-rings or brine seal if damaged.
Set the membrane aside in a clean space and continue on to step 5.
5. Remove the end caps from both ends of all membrane housings on your
machine. This is done by loosening the clamp bolts at each end cap closure
assembly.
6. Determine the direction of fluid flow in the membrane housing. (Be certain to
look at the "Direction of Flow" arrow for each membrane housing. Direction of
flow may vary within a given machine.)
7. Inspect the membrane housing and clean as necessary to remove any
contaminants, obstructions, etc.
8. Apply a small amount of O-ring lubricant to all O-rings on the end caps, and
the brine seal on the membrane.
9. Insert the downstream end of the membrane in the upstream end of the
membrane housing (i.e., load in the direction of flow; the brine seal is on the
end of the membrane that goes in last. For membrane housings with the flow
arrow pointing up refer to step 11).
10. Insert the membrane in the membrane housing with a smooth and constant
motion. When you reach the point where the brine seal is about to enter the
housing, gently turn the membrane to ensure the brine seal enters the
housing without coming out of the brine seal groove.
11. When all of your membranes are installed, you must close the membrane
housing package by re-installing the end caps and clamps. It is preferred to
install the bottom end cap first, and tighten the clamp completely, before
installing the top end cap.
12. Re-install the end caps by gently twisting the end cap while pushing it on to
the permeate tube. Ensure that you do not pinch or fatigue any O-rings while
pushing the end cap on. Push the end cap on until the outer diameter of the
cap is flush with the outer diameter of the membrane housing. Install the
clamp halves, and tighten the bolts until the clamp halves meet.
13. Re-connect any fittings that were removed when disassembling the
membrane housings.
