5. Slowly remove the membrane from the pressure vessel being careful not to grasp it by the
permeate tube. Needle nose pliers may be necessary to pull out the old membrane element.
This may take a bit of force to do as the membrane may have come tightly pressed to the walls
of the vessel. Upon removing set aside. The figure below shows the proper way to grip the
membranes if they cannot be removed by hand.
Inserting the New Membrane
1. Remove the replacement membrane element(s) from the shipping box; the membrane(s) should
be contained within a plastic oxygen barrier bag.
2. Cut the bag open as close as possible to the seal at one end of the bag, so the bag may be
reused if necessary.
3. Make sure that all parts are clean and free from dirt. Examine the brine seal and permeate
tube for nicks or cuts. Replace the O-rings or brine seal if damaged.
4. Lubricate the Brine Seal with a food grade lubricant. We recommend Molykote® 111 Compound.
5. Install the membrane element so the brine seal will be located at the supply side of the vessel.
CAUTION
Removing the membrane in the orientation shown above can only be done if you will replace it with a
new membrane. If the membrane is to be reused it must be removed in the flow direction shown by
the arrow. This is opposite to the direction shown in the picture above.
NOTE Wear gloves for the following steps to not contaminate the membrane.
CAUTION
The membrane can only be inserted in one direction. Installing the membrane from the wrong
direction will cause the seal to not seat properly resulting in poor membrane performance. When
inserting, be careful not to tear or flip the brine seal. Relubricate the brine seal if necessary.
