- 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 16. Check Your Water Supply: The cold water supply to

the RO system must be within certain quality limits. See the specification table on page 16. 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 13.

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,

and this manual.

- 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 17).

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 17. 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 8, page 8). A typical connection

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

Note: Codes in the state of Massachusetts require 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

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 17, 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.

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 8, page 8).

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

0 Drill a new hole in the countertop next to the sink.

0 Drill a new hole in the sink top.

Figure 5

CAUTION: Drilling holes into countertops made of stone or solid surface materials such as granite,

marble, Corian T_ or other plastic resin products or sinks made of porcelain and stainless steel should only be performed by a fabricator installer who is cer- tified for fabricating such materials. Drilling of these type surfaces by any other means may cause perma- nent, irreparable damage to the countertop surface.

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