- SAFETY GUIDES -

• Read all steps and guides carefully before instal- ling 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.

• 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 wa- ter, or water of unknown quality without adequate disinfection before or after the system. This system is certified for cyst reduction and may be used on

disinfected water that may contain filterable cysts.

• Check with your local public works department for plumbing and sanitation codes. You must fol-

low their guides as you install the system. Follow your local codes if they differ with guides in this manual. Massachusetts plumbing code 248 CMR shall be adhered to. Please consult your licensed plumber.

• This system shall only be used for arsenic reduc- tion on chlorinated water supplies containing de- tectable residual free chlorine at the system inlet.

Water systems using an inline chlorinator should provide a one minute chlorine contact time before the RO system.

• This system is acceptable for treatment of influ-

ent concentrations of no more than 27 mg/L nitrate and 3 mg/L nitrite in combination measured as N

and is certified for nitrate/nitrite reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater. This system is supplied with a nitrate/ni-

trite test kit. Product water should be monitored pe- riodically according to the instructions provided

with the test kit.

• The reverse osmosis system works on water pres- sures 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 out- side, or in extreme hot or cold temperatures. Temper- ature of the water supply to the reverse osmosis sys-

tem must be between 40°F and 100°F. Do not install on hot water.

• Read the other limits (pH, hardness, etc.) in the specifications and be sure your water supply con- forms. Also see "Water Supply" on page 4.

- WHAT YOUR REVERSE OSMOSIS SYSTEM WILL DO -

Your Reverse Osmosis (RO) Drinking Water System is a water treatment unit. It uses household water

pressure to reverse a natural physical process called osmosis. Water, under pressure, is forced through a semi-permeable membrane where minerals and im- purities are filtered out. Clean drinking water goes to the faucet or storage, while minerals and impurities

are sent to the drain with RO waste water. The miner- als and impurities are measured in water as total dis-

solved solids (TDS). The system includes replaceable pre and postfilter

sediment-carbon cartridges. The prefilter removes sand, silt, dirt, rust particles, other sediments, and

chlorine from the water supply before it can enter the

RO membrane. The postfilter removes any tastes and/or odors that may remain in the water, after

passing through the RO membrane, and just before going to the RO faucet. To prevent water waste, an

automatic shutoff valve closes when the RO faucet is closed and the storage tank is full.

Your reverse osmosis system gives you a continuous supply of sparkling clear, delicious water for drink- ing, cooking and other uses. Foods will look and

taste better too. Having high quality RO product wa- ter at your fingertips eliminates the need to buy

bottled water. The storage tank holds over 2 gallons

of RO product water for your needs.

- BEFORE YOU BEGIN TO INSTALL THE RO SYSTEM -

FOR OPTIMUM PERFORMANCE YOUR KEN- MORE REVERSE OSMOSIS SYSTEM SHOULD BE

INSTALLED ON SOFTENED WATER. CAUTION: A refrigerator icemaker may not operate

properly when connected to a reverse osmosis sys- tem that has been installed on a water system that op- erates outside of the specified pressures listed on

page 18. Check Your Water Supply: The cold water supply to

the RO system must be within certain quality limits. See the specification table on page 18. If supply water

is not within limits, the RO system can not make product water as it should and reduced RO mem-

brane life will result. Trained sales people at Sears can perform a free water

analysis. This basic test can help determine if any additional water treatment is required before the RO

system.

CAUTION: Chlorine in the water will destroy the RO membrane. Most cities add chlorine to the water

supply to kill bacteria. The prefilter removes chlorine up to the limits shown in the specifications before it

enters the RO membrane. It is important to replace

the prefilter cartridge at least every 6 months. See the RO care guide on page 15.

Check Parts Included: Unpack the carton and re- move the RO system. In addition to the assembled

RO and the storage tank, the system includes the parts illustrated below, a separate length of tubing,

- WHERE TO INSTALL THE RO SYSTEM -

The RO assembly and storage tank is designed for installation under the sink, usually in the kitchen or bathroom. The RO assembly mounts on a wall sur- face, or can lay on the cabinet floor next to the storage

tank. Hanger washers and wood screws are included for cabinet wall mounting. The RO product water faucet installs on the sink, or on the countertop next to the sink (page 6).

Note: Tubing lengths allow for the removal of the as- sembly from the hanger washers for servicing. If tub-

ing lengths are shortened for neater appearance, it may be necessary to keep the assembly on the hanger

washers for service. You can also locate the R© assembly and storage tank

in any remote location from the faucet, observing safety guides on page 2. You do need a nearby water source and drain point (see page 19).

Water Supply: To provide supply water to the RO system inlet use the included feed supply fitting or install pipe fittings for tubing connection, as typical-

ly shown on page 5.

Drain Point: A suitable drain point is needed for re-

ject water from the RO membrane. A floor drain,

laundry tub, standpipe, sump, etc., is preferred, as shown in the remote locations drawing, page 19. A

sink p-trap drain adaptor is included to install where codes permit, as an optional drain point (page 6).

- STEP 1: INSTALL COLD WATER SUPPLY FITTING -

Check and comply with local plumbing codes as you plan, then install a cold feed (supply) water fitting. The fitting must provide a leak-tight connection to the RO 1/4" tubing (see Figure 10, page 10). A typical connec-

tion using the included water supply fitting is shown in Figure 3A below. An optional connection, using stan- dard plumbing fittings (not included), is shown in Figure 3B.

Note: Codes in the state of Massachusetts _vquire installation by a licensed plumbe_, and do not permit the use of a saddle valve. For installation, use plumbing code 248-CMR of the Commonwealth of Massachusetts.

A. WATER SUPPLY FITTING

1. Close the house main water shutoff valve and open faucets to drain water from the sink cold water pipe.

2. Remove nut that connects the cold water faucet to cold water plumbing.

3. Use pipe joint compound or Teflon tape on cold water faucet stud threads and on the mate threads of the water

supply fitting that connect to the cold water pipe.

B. OPTIONAL PIPE FITTINGS (compression type shown)

Note: Be sure to turn off the water supply and open

a low faucet to drain the pipe. Complying with plumbing codes, install a fitting on

the kitchen cold water pipe to adapt 1/4" ©D tubing. A typical connection is shown in Figure 3B. If

threaded fittings are used, be sure to use pipe joint compound or Teflon tape on outside threads.

4. Thread water supply fitting onto pipe and reconnect nut to bottom of fitting.

- STEP 2: INSTALL DRAIN ADAPTER -

• Note: Running the drain tubing directly to a floor

drain, sump, standpipe, laundry tub, etc., as shown on page 19, is preferred. However, if that is not pos- sible or practical, the included drain adapter installs in the sink drain pipe, always above or ahead of the

p-trap, Figure 4. Be sure to comply with your local plumbing codes. Other drain pipe fittings, in addi- tion to the adapter, may be needed.

• The drain adapter fits 1-1/2" sink drain pipe.

• The adapter installs directly onto the sink tailpiece

as typically shown in Figure 4 and Figure 5.

• Locate so drain tubing from the faucet makes a

straight run to the adapter, without dips, loops, low spots or kinks.

Note: Consult a plumber if you are not familiar with plumbing procedures.

1. Use a ferrule and nut to assemble the drain tubing connector to the drain adapter (Figure 5). Turn the

connector to about 45 ° from the 12:00 position, as shown (to 10:00 or 2:00 position as needed). Tighten

the nut securely.

P-trap

Figure 4

2. Carefully disassemble the sink drain pipe and clean the tailpiece to assure a leak-tight fit.

3. Install the drain adapter onto the sink tailpiece, using a ferrule and nut. Snug the nut, but do not tighten.

Note: If needed, to make fit, you can cut to shorten the unthreaded end of the adapter. Do not cut too short

so the adapter will make a leak-tight seal with the connecting fitting.

4. Assemble the p- trap to the drain adapter, and oth- er drain pipe fittings as required (check codes) to complete the drain run.

5. Tighten all connections, but do not overtighten and break plastic fittings.

- STEP 3: INSTALL FAUCET -

A. PREPARE MOUNTING HOLE

1. Select one of the following places for the faucet. Be sure it will fit flat against the surface, and there is space underneath for tubing (see Figure 10, page 10).

0 Use an existing sink top hole for a spray hose or other faucet. A 1-1/4" diameter hole is needed.

J Drill a new hole in the countertop next to the sink. t Drill a new hole in the sink top. CAUTION: Drilling holes into countertops made of

stone or solid surface materials such as granite,

who is certified for fabricating such materials. Dril- ling of these type surfaces by any other means may cause permanent, irreparable damage to the counter-

top surface.

2. If drilling is needed, make the 1-1/4" diameter hole.

3. Place plumbers putty around the drilled hole (Figure 6 and Figure 7) to prevent water leakage

around the base of the faucet.
