WARRANTY
In addition
to any warranty
extended
to you on the
Sears merchandise
involved,
which

- SAFETY GUIDES • Read all steps and guides carefully
before installing and using your reverse osmosis system. Follow
all steps exactly
to correctly
install.
Reading
this
manual
will also help you to get all the benefits from
the reverse osmosis system.
•
The reverse osmosis system works on water pressures of 40 psi (minimum)
to 100 psi (maximum).
If
your house water pressure
is over the maximum,
install a pressure
reducing
valve in the water supply
pipe to the reverse osmosis
system.
•
Do not install the reverse osmosis
system outside, or in extreme hot or cold temperatures.
Temperature of the water supply to the reverse osmosis system must be between
40°F and 100°F. Do not install
on hot water.
•
Do not attempt to use this product to make safe
drinking water from non-potable
water sources. Do
not use the system on microbiologically
unsafe water, or water of unknown
quality without adequate
disinfection
before or after the system.
•
Read the other limits (pH, hardness, etc.) in the
specifications
and be sure your water supply
conforms. Also see "Water Supply"
on page 3.
•
Check with your local public works department
for plumbing
and sanitation
codes. You must follow their guides as you install the system. Follow
your local codes if they differ with guides in this
manual.
•
The reverse osmosis membrane
contains
a preservative
for storage and shipment.
Be sure to purge
as instructed
on page 9 before using product
water.

on page 18, is preferred.
However,
if that is not possible or practical,
the included

plumbing
codes. Other drain pipe fittings, in addition to the adapter, may be needed.

FAUCET
The prefilter
has a replaceable
sediment
cartridge
with activated
carbon in its composition.
The cartridge (10 micron) removes sand, silt, dirt, other sediments, and up to the ppm of chlorine
shown in the
specifications
from the feed water. Chlorine
will destroy the RO membrane.
Filtered,
clean, chlorinefree water flows from the prefilter,
to the RO membrane cartridge.

- CARE OF YOUR REVERSE OSMOSIS
To keep your reverse osmosis system operating
and
producing
high quality water, you must make sure
supply water is always within the limits shown in the
specifications.
Good supply
water helps to assure
longer life from the RO membrane
cartridge,
prefilter
and postfilter
cartridges.
However,
each of these will
wear out in time and need replacement.

and end caps. The postfilter

This reverse osmosis system contains a replaceable
treatment component
critical for effective removal of

periodically
to verify the system is performing

opposite way to install
and tighten.
RO MEMBRANE
The life of the RO membrane
cartridge
depends
mostly on the pH of the supply water to the RO system (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 1 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.
If the water has sediments
only, with no chlorine, you
may notice a slower making of product
water as the
prefilter collects the sediments.
When this occurs, replace the prefilter cartridge.
Also replace the post filter
cartridge.

GUIDE
1. AT LEAST every 6 months, replace the prefilter and postfilter cartridges. Clean or replace the flow control and
screen.
2. Replace the RO membrane cartridge when the percent rejection of total dissolved solids (TDS) is less than shown
in the specifications (see B, below).
If any of the following occur before the 6 months, replace as directed.
A. Slow Making of Produot Water: Replace the prefilter cartridge.
If the production rate does not improve, replace the post filter cartridge and RO membrane cartridge.
C. Ch/orine Tasteand/or Odor: Replace the prefilter,post filter and
RO membrane cartridges.
B. High Total Dissolved Solids (TDS) in Product Water: You can
get a free TDS test through some Sears retail stores or service
departments. If the store or service department does not have a
TDS meter, you can send treated and untreated water samples to
a water analysis lab for testing. It is important to test both the
treated and untreated water to determine system performance. If
the TDS is not within the system's performance guidelines,
replace the prefilter, post filter and RO membrane cartridges.

You can run the drain tubing directly to 1 of several suitable open drain points, as shown below, bypassing
the faucet airgap and p-trap drain. This type of drain is the preferred over the p-trap drain adapter. Check
