FCI WATERMAKERS, INC. 116 Maintenance & Repair
MEMBRANE REPLACEMENT
MEMBRANE REPLACEMENT PROCEDURE
As your Watermaker ages, your membrane will start to deteriorate and produce
lower grade water. When this happens you may try to chemically clean the
membrane(s) to recover the performance. Refer to "CLEANING PROCEDURE"
on page 120. If this fails you will need to replace the membrane.
Refer to
Figure 26 on page 117 and proceed as follows:
1 Shut the thru‑hull, and disconnect the high‑pressure (and low‑pressure
if needed) hose connections from the end of the vessel in question.
2 Using a 9/16 open‑end wrench and a slotted screwdriver, remove
the four (4) nuts on the end of the pressure vessel.
3 With the nuts off, push the rods back clear of the black anodized plate.
4 Holding the black anodized plate in both hands, twist and pull the plate
clear of the vessel. The end plug assembly will be removed with the plate
and the membrane will now be visible inside the pressure vessel.
5 Using a pair of needle‑nose pliers, grab the exposed white tube. With a firm
grip, pull the membrane out of the vessel. If you are taking the membrane(s)
out to be returned to FCI for evaluation, do not damage or mar the white
tube— doing so will make it impossible for us to evaluate the membrane.
6 Notice the position of the Brine‑Seal when the membrane was pulled from
the vessel. There is only on brine seal per membrane. The cup portion of
the seal must face the incoming flow from the high‑pressure pump.
7 Take the new membrane out of the bag. Take care
NOT to get the membrane dirty.
8 If the old membrane is being returned to FCI, rinse well with fresh water
and place into the bag. Seal the end with tape and return immediately.
9 With the new membrane in hand, lubricate the brine seal and
slide into the vessel in the same position as the original came
out. Be sure the brine seal has not become unseated.
10 Inspect the o‑rings on the end plug, replace if needed,
lubricate the o‑ring and slide into the vessel.
11 Slide rods forward through the mounting holes and re‑assemble nuts.
Tighten until the washer does not spin freely. DO NOT OVERTIGHTEN
12 Reconnect the hoses.
