element housing. As you reach the bottom of the housing slowly guide the PVC
stem or stinger on the end of the membrane element into the head of the end cap.
As the membrane element slides into the housing the brine seal will be on the top
(Figure 2.4, Direction of Membrane Element Installation).

3. Next, load the up flow membrane elements, by lubricating all brine seals, O-rings,
and the membrane element stingers. With the up flow membrane element and the
brine seal will be on the bottom of the membrane element. Turn the membrane
element slowly as you lower it down into the housing. As with the down flow
membrane element, one must slowly guide the PVC stinger on the end of the
membrane element into the end cap.
4. Reinstall the end caps by using non-petroleum based lubricant to lubricate the O-
ring inside the end cap. Reinstall the end cap on the membrane element by first,
aligning the stinger into the hole in the end cap and then turn the end cap slowly
clockwise, as you push it down into the membrane element housing.
5. Reattach the housing clamp and tighten.
6. Reattach the feed line and flush permeate and concentrate lines to the drain for
25 - 30 minutes.
7. Take appropriate tests to insure biocide has been flushed from the machine.
8. Reconnect permeate line to point-of-use.
9. The machine is now ready for operation.
