MEMBRANE REPLACEMENT
NEVER FORCE A MEMBRANE OUT OF A PRESSURE VESSEL BY APPLYING PRESSURE ON
THE PRODUCT WATER TUBE (CENTER TUBE), AS THIS WILL DAMAGE THE MEMBRANE. IF
MEMBRANE IS DIFFICULT TO REMOVE, USE A 2” DIAMETER PLASTIC PIPE (PVC) TO APPLY
PRESSURE ON THE PROTECTED END OF THE MEMBRANE.
6.2 PRESSURE VESSEL ASSEMBLY
Step 1:
Lubricate O-rings and entrances to pressure vessel with glycerin or silicone lubricant. Locate discharge
end of pressure vessel. Install discharge end plug by lining up with the holes of the pressure vessel,
paying attention to the reference mark. Position end cap ring and insert fasteners handtight.
NEVER USE ANY TYPE OF LUBRICANT CONTAINING PETROLEUM OIL. OIL CAN DAMAGE
YOUR UNIT AND REDUCE MEMBRANES PERFORMANCE.
Step 2: Align the membrane so the end without the brine seal enters the feed end of the pressure vessel first.
Slide membrane into pressure vessel until resistance is felt. Continue applying pressure until the
product water tube sits into the end plug.
Step 3:
Install the remaining end plug (align end plug holes with mounting studs properly), use the reference
mark made in step 3 for correct assembly.
Step 4:
Tighten the six fasteners for each end cap.
Step 5:
Reconnect plumbing to pressure vessel(s).
NOTE: Do not apply Teflon tape or sealant to SAE (straight thread) fittings such as those used on High
Pressure assemblies and their adapters. Use only on NPT taper thread fittings.
NOTE: For replacement parts call numbers, refer to Parts Reference section at the end of the manual
and for additional information about the membranes and the pressure vessel, refer to the
Manufacturer’s Literature section at the back of this manual.
