PREFILTER / POSTFILTER MAINTENANCE

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.

See Fig. 28. You must periodically replace the prefilter

and postfilter cartridge. This will protect the RO mem-

brane from being destroyed by chlorine. It will also pre-

vent the filters from plugging with sediment.
You may notice a slower output of product water as

the prefilter and postfilter build up with sediment.

Replace the prefilter and postfilter cartridges when this

occurs. You should replace the battery whenever you

replace the cartridges.

RO MEMBRANE CARTRIDGE MAINTENANCE

The Reverse Osmosis cartridge is a tightly wound spe-

cial membrane. See Fig. 28. 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 pin-hole leaks. It's time to

replace the Reverse Osmosis cartridge when the pro-

duction 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 CARTRIDGE REPLACE-

MENT

Complete the following steps to replace the cartridges.
NOTE: Do not remove manifold from mounts.

Flexing or twisting may damage the manifold.
1. Remove (turn to the left) 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 (post filter,

Reverse Osmosis and then prefilter). Turn cartridges

to the right to reattach to the filter heads. Do not

overtighten.

6. Remove and replace the timer battery. See page 15.

7. Purge the Reverse Osmosis system. See page 19

for instructions.

REPLACEMENT

Complete the following steps to replace the cartridges.
NOTE: Do not remove manifold from mounts.

Flexing or twisting may damage the manifold.
1. Remove the prefilter cartridge (turn to the left) from

the filter head. 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 to the right to re-

attach to the filter heads. Do not overtighten.

4. Remove and replace the timer battery. See page 15.

5. Purge the Reverse Osmosis system. See page 19

for instructions.
