- 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 doses 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 arrange for a free

water analysis. The analysis will tell you if other wa- ter supply treatment is needed before going to the RO system.

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

ter 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 16.

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 (pages 6 and 7).

Note: Tubing lengths allow for the removal of the

assembly from the hanger washers for servicing. If tubing lengths are shortened for neater appear- ance, it may be necessary to keep the assembly on the hanger washers for service.

You can also locate the RO assembly and storage tank

FIG. 2 ]

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 p4rap 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 FIG. 8, page 8). A typical connection using the included water supply fitting is shown in FIG.3 - A below. An optional connection, using standard plumbing fittings (not included), is shown in B.

Note: Codes in the state of Massachusetts require installation by a licensed plumber, 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 male threads of the water

supply fitting that connect to the cold water pipe.

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

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" OD 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.

- 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 (FIG. 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 FIG. 4 and 5.

• Locate so drain tubing from the faucet (installed in step 1, page 8) 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 (FIG. 5). Turn the con- nector to about 45 ° from the 12:00 position, as shown

(to 10:00 or 2:00 position as needed). Tighten the nut

securely.

I FIG. 5 ]

F-1

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 FIG. 8, page 8).

@Use an existing sink top hole for a spray hose or other faucet. A 1-1/8" to 1-1/4" diameter hole is needed.
