CARTRIDGE LIFE AND REPLACEMENT

PREFILTER / POSTFILTER CARTRIDGE LIFE
NOTE: It is recommended to replace the battery,
prefilter and postfilter cartridges at least every
6 months of product water use. Replace more
often if they begin to plug with sediment.
The prefilter and postfilter are replaceable sediment
cartridges with activated carbon in their composition.
The prefilter and postfilter cartridges must be
periodically replaced. This will protect the RO
membrane from being destroyed by chlorine. It will
also prevent the filters from plugging with sediment.
Slower output of product water may be noticed as the
prefilter and postfilter build up with sediment. Replace
the prefilter and postfilter cartridges when this occurs.
Replace the faucet battery whenever you replace the
cartridges.
PREFILTER / POSTFILTER CARTRIDGE
REPLACEMENT (every 6 months)
Complete the following steps to replace the prefilter
and postfilter cartridges.
1. Remove (turn counterclockwise) the prefilter
cartridge from the manifold. Then remove the
postfilter cartridge.
2. Discard the cartridges in a proper manner.
3. Install new cartridges in reverse order: postfilter first,
then prefilter. Turn cartridges clockwise to reattach
to the manifold. Do not overtighten.
4. Remove and replace the faucet timer battery. See
next page for instructions.
5. Purge the Reverse Osmosis system. See previous
page for instructions.
REVERSE OSMOSIS MEMBRANE CARTRIDGE
LIFE
The Reverse Osmosis cartridge is a tightly wound
special membrane. The membrane reduces the
dissolved solids and organic matter. The life of the
Reverse Osmosis membrane cartridge depends mostly
on the pH and hardness of the supply water (see
Specifications). Cartridge life is shorter with higher
pH. For example, if supply water pH is from 6.8 to 7.7,
the cartridge may last for well over one year.
However, cartridge life may be as short as 6 months if
the pH is as high as 8.5 to 10. Higher pH weakens the
cartridge membrane and causes pinhole leaks. It Is
time to replace the Reverse Osmosis cartridge when
To obtain replacement filters, call toll-free GE Appliances Parts and Services at 800.952.5039 (US),
or visit the store where you purchased your reverse osmosis system.

the production rate and/or quality of product water
drops. Product water may begin to taste different,
indicating solids and organics are passing through the
Reverse Osmosis membrane. See Reverse Osmosis
cartridge replacement.
REVERSE OSMOSIS MEMBRANE CARTRIDGE
REPLACEMENT
Complete the following steps to replace all cartridges
when replacing the RO membrane.
1. Remove (turn counterclockwise) the prefilter
cartridge from the manifold to stop flow to the
Reverse Osmosis cartridge.
2. Remove the Reverse Osmosis cartridge.
3. Remove the postfilter cartridge.
4. Discard the cartridges in a proper manner.
5. Install new cartridges in reverse order: postfilter,
Reverse Osmosis and then prefilter. Turn cartridges
clockwise to reattach to the manifold. Do not
overtighten.
6. Remove and replace the faucet timer battery. See
next page for instructions.
7. Purge the Reverse Osmosis system. See previous
page for instructions.
REMINERALIZATION / ANTIMICROBIAL FILTER
LIFE AND REPLACEMENT
NOTE: It is recommended to replace the
Remineralization/Antimicrobial Filter at least
every 12 months of product water use.
Complete the following steps to replace the filter:
1. Remove the tubes from inlet and outlet by pressing
down each collet and pulling the tube out.
2. Slide the filter out of the mounting bracket.
3. Discard the filter in a proper manner.
4. Slide the new Remineralization/Antimicrobial Filter
into the mounting bracket, with the INLET end UP.
5. Insert the tube from the Reverse Osmosis assembly
all the way into the INLET collet fitting.
6. Insert the tube from the product water faucet all the
way into the OUTLET collet fitting.
7. Pull on the tubes to be sure they are held firmly in
the fittings.
8. Purge the Reverse Osmosis system. See previous
page for instructions.
