PRE-FILTER/POST-FILTER MAINTENANCE
NOTE: It is recommended to replace the battery,
pre-filter and post-filter cartridges at least every 6
months of product water use. Replace more often if
they begin to plug with sediment.
The pre-filter and post-filter are replaceable sediment
cartridges with activated carbon in their composition. See
Fig. 24. You must periodically replace the pre-filter and
post-filter cartridge. This will protect the RO membrane
from being destroyed by chlorine. It will also prevent the
filters from plugging with sediment.
You may notice a slower output of product water as the
pre-filter and post-filter build up with sediment. Replace
the pre-filter and post-filter 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 special
membrane. See Fig. 24. 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 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 CARTRIDGE 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 (turn to the left) the pre-filter cartridge from
the manifold to stop flow to the Reverse Osmosis
cartridge.
2. Remove the Reverse Osmosis cartridge.
3. Remove the post-filter cartridge.
4. Discard the cartridges in a proper manner.
5. Install new cartridges in reverse order (post-filter,
Reverse Osmosis and then pre-filter). Turn cartridges
to the right to reattach to the filter heads. Do not
overtighten.
6. Purge the Reverse Osmosis system. See page 14 for
instructions.
