5.14 Membrane Element Replacement
As time progresses, the efficiency of the membrane elements will begin to
decline. Generally, the salt rejection of the membrane will not change
significantly when properly operated on water until about two years after
installation. Under ordinary conditions, the permeate rate may decline
slightly after one to two years of operation. This period can be extended
with frequent flushing and cleaning as outlined in these instructions.
If the membranes are to be saved, they must be cleaned and then
sanitized before removal from the machine.
Verify the membranes’ part number before replacing them. Reference
Table 5.9 for the correct parts needed to replace the membranes.

5.14.1 Membrane Element Removal
1. Disconnect the permeate tubing from the permeate
manifold.
2. Remove the end cap and housing adapter from the
membrane element housing.
3. Remove the membrane element from the membrane
element housing.
4. Inspect the membrane element housing. Clean as
necessary to remove any contaminants, obstructions,
etc.
5.14.2 Membrane Element Installation
CAUTION:
Membrane elements are packaged with a small amount of biocide solution
to prevent biological growth. Provide adequate ventilation and use
protective gloves and eye protection when handling. Membrane elements
must be kept moist at all times in order to prevent possible damage to the
membrane material.
