1. Remove one membrane element at a time from the membrane element
housings, from the top of the housing. Long nose pliers may be necessary to pull
the old membrane element out of the membrane element housing.
2. Lubricate the brine seal with non petroleum based lubricant, Silicone DC 111.
3. Install the brine seal side of the membrane element first (Figure 4, Page 31).
When the housings have a direction of flow from bottom to top, the brine seal
should be located at the bottom of the housing.
4. At a slight angle, insert the membrane while slightly rotating the element being
careful not to tear or flip the brine seal. A slow twisting motion should be used to
insert the membrane element, to ensure the brine seal stays in place. Re-lube
the brine seal if necessary.
5. With a smooth and constant motion, push the membrane element into the
housing so the brine seal enters the housing without coming out of the brine seal
groove.
6. Re-install the end caps by gently twisting the end cap while pushing it onto the
housing. Ensure that you do not pinch or fatigue any O-rings while re-installing
the end plug. Push the end plug on until the outer diameter of the plug is flush
with the outer diameter of the membrane housing.
7. Insert the snap ring until it is fully seated. Install the locking clip if available.
8. Reconnect any fittings that may have been disconnected when the membrane
element housings were disassembled.
9. To start-up the system, please refer to the Initial Start-Up section of this manual.
