MEMBRANE REMOVAL AND REPLACEMENT
Replacing membranes in the pressure vessels is an easy process if you have the proper information and
tools at hand.
Please refer to the following instructions when removing and replacing membrane
elements:
WARNING: ALL PRESSURE GAUGES MUST READ ZERO BEFORE PROCEEDING.
BEFORE ATTEMPTING, DISCONNECT THE POWER FROM THE SYSTEM AND BLEED ALL WATER
PRESSURE FROM THE SYSTEM.
1.
Remove the end plugs from the top of the pressure vessels. This is done by removing the two
half-moon retaining disks using a #5 Allen wrench; the end plugs should then freely slide out of
the pressure vessel.
2.
Remove the replacement membrane element(s) from the shipping box; the membrane(s) should
be contained within a plastic oxygen barrier bag.
NOTE: WEAR GLOVES FOR THE FOLLOWING STEPS IN ORDER NOT TO CONTAMINATE THE
MEMBRANE.
3.
Cut the bag open as close as possible to the seal at one end of the bag, so the bag may be re-
used if necessary.
4.
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.
5.
Flow directions should be observed for installation of each element into their respective pressure
vessels.
