Replacing Membranes
Tools:
Rubber Mallet - Flat Blade Screwdriver - Food Grade RT-111 silicone - Safety Glasses.
Procedure
1.
Turn off the RO system.
2.
Relieve pressure on the membrane array – open Control valve.
3.
Remove all lines from both ends of the pressure vessel(s). Please make sure that the fittings are marked – so it
can go back to the correct locations.
4.
Pull U-pins from top of vessel and remove end cap. Grasp end of element using pliers - as shown in photo and
pull upward until a firm hand grip is established to further remove the element from the vessel.
5.
Install the new element such that the brine seal (big black exterior o-ring) is positioned in the feed end of the
vessel. The flow arrow points away from the feed end. In multiple vessel units, the Flow direction will alternate
between vessels. Check / ensure that the end adapters and all o rings are in good condition and in position.
Note: Brine seal flared end should ‘cup’ toward the feed end. Refer to illustration 14.
6.
Replace end plug(s) using glycerin or silicone lubricant (Part No. H-C111DC) as required on O rings and seal. It
is highly recommended to have a spare set of O-rings and brine seal while replacing the elements.
7.
As the elements may have preservative or be contaminated - wash your hands thoroughly after replacing.
