7.
Remove the membrane product tube adapters from the old membrane elements if they did
not remain on the vessel end caps and keep them. Dispose of the old membrane
elements.
8.
Check the o-rings on the interconnectors for damage and replace any that show signs of
wear or damage. (It is a good idea to replace all the o-rings at the same time you replace
the RO membrane elements). Apply a liberal coating of glycerin to the o-rings and brine
seals before they are inserted back into the pressure vessel.
9.
Remove enough new RO membrane elements from the protective packaging to fill one
pressure vessel.
10.
Install the interconnectors between the RO membrane elements as you load them into the
vessel.
11.
Load the new membrane elements in the pressure vessel in the same direction as the flow
arrowhead sticker. Make sure that the membrane brine seal is on the end to enter the
pressure vessel last.
NOTE:
The flow arrow on the new RO membrane element should match the flow arrowhead
sticker on the pressure vessel.
12.
Carefully reinstall the product tube adapters on the ends of the membrane element
product tubes. Apply a liberal amount of glycerin on the o-rings to make installation
easier.
13.
Carefully reinstall the end caps back in the ends of the pressure vessel,
taking care to put
them in the same ends that they came out of
. Use a small amount of glycerin on the o-
rings to make installation easier.
14.
Carefully tap the end caps into place, using the rubber mallet. Re-assemble the end cap
assembly per manufactures instructions.
15.
Carefully reinstall the retaining rings in both ends of the pressure vessel.
16.
Once all the membranes are replaced, reinstall the product piping connections.
17.
Check all connections and vessels carefully.
The RO unit is now ready to be put back into service.
