???Do not attempt to use this product to make safe

??? 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.

???The reverse osmosis membrane contains a pre-

servative for storage and shipment. Be sure to purge as instructed on page 11 before using product water.

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.

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

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, and this manual.

Figure 1

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).

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.

FAUCET ELECTRONICS

The faucet will measure the length of time the filters have been installed (6 months). The faucet has an in-

dicator LED that flashes to inform you of the status of the filter.

Green - Filter is good. Red - Filters need replacing.

In order to reset the monitor time feature, the battery should be removed for a minimum of five seconds and then reinserted.

The battery needs to be replaced when indicater LEDs no longer light. Use only 3 volt sealed lithium batteries. Improper placement of battery could dam- age electronics. Use care when inserting battery to align it correctly.

To change the battery, pull the spout and bezel from the faucet base. The bezel will stay on the spout. Pinch the two tabs (under bezel on faucet) with one hand and with the other, pull up on the knob.

Change battery. Assemble the the knob, and spout and bezel back onto the faucet base.

1.CONNECT DRAIN TUBING, FAUCET TO

DRAIN ADAPTER: Referring to Figure 10, run the loose section of black 3/8" tubing from the faucet to the drain adapter, with a black collet, installed on page 6. Cut this tubing as needed to route in as straight of a run as possible, without loops, dips, low spots or kinks. Cut the end of the tubing square. Then push all the way into the fitting. Pull on the tub- ing to be sure it's held firmly in the adapter fitting. See page 16 for tubing connection instructions.

2. CONNECT TUBING TO WATER SUPPLY: Con- nect the feed (green) tube to the water supply fitting installed on page 5. Connection to the fitting is as

SANITIZING

Sanitizing is recommended upon installation of the RO system, and after servicing inner parts. It is im- portant for the service person to have clean hands while handling inner parts of the system.

CA UTION: Be sure to remove the RO membrane and both filter cartridges as follows, before sanitizing.

Chlorine will destroy the RO membrane cartridge.

1. Be sure the water supply to the RO is turned off, and the RO faucet is open to relieve pressure.

2.Referring to Figure 12, page 14, remove the R?? membrane sump by twisting 1/4 turn left (_D). Re- move the R?? cartridge from sump. Place the car- tridge in a clean plastic bag.

3.Be sure the o-ring seal is on the sump. Replace the RO sump by turning to the right (k,) to lock.

4.Remove the postfilter sump, turning to the left. Take the cartridge from the sump and place in the plastic bag. Replace the sump by turning to the right (k_) to lock.

5.Remove the prefilter sump and cartridge. Also place this cartridge in the clean bag.

PRESSURE TESTING

1.Do the preceding sanitizing procedures before pressure testing.

2.Open the water supply shutoff valve to the RO.

3.Open the main water supply valve and several

house faucets to purge air from the system. Close faucets when water runs smooth.

PURGING RO MEMBRANE

Important pmxing instructions: The RO cartridge contains a food _ade preservative that should be rinsed before using water from the system. The preserva- tive will give product water an unpleasant taste and odor.

6. If needed to clean, flush the prefilter sump with fresh water. Then fill with water to about 1" from the

top. Add 1.0 ounce of chlorine (ordinary 5.25% household bleach...Hilex, Clorox, etc.) and mix in the water. Do not add chlorine first. Concentrated it will

attack plastics.

7.Carefully replace the sump on the prefilter head and turn to the right (k_) to lock.

8.Slowly open the water supply to the RO.

9.Open the R?? faucet by turning knob to the left.

10.Allow water to circulate through the R?? system

until you smell the bleach odor at the faucet. Then close the faucet and allow the R?? to stand idle for 20 minutes.

11.After the 20 minutes open the R?? faucet and run water until the bleach odor is gone.

12.Turn off the water supply to the R??.

13.Be sure your hands are clean. Then, repeat steps

1- 5 and 7, only replace all cartridges.

Important: Refer to Figure 12, page 14, and to page 15 when replacing cartridges. The prefilter (left side) cartridge and the postfilter (right side) have puple end caps.

4. In about 2 hours, pressure will start to build in the RO system. Then, carefully check all fittings and con- nections for water leaks. Correct leaks if any are found.

Note: When the system is first pressurized, water may "spurt" from the faucet airgap hole until air is expelled from the RO system.

1.Allow the storage tank to fill for about 4 hours. Then open the R?? faucet until the tank is empty and flow stops. Close the RO faucet.

2.Repeat step 1 five more times (for a total of 6) to purge the RO system. Then the RO system is ready

to make product water for use.

PREFILTER

Water from the cold supply pipe enters the RO as- sembly prefilter first (Figure 10, page 10, and sche- matic, page 13).

The prefilter has a replaceable sediment cartridge with activated carbon in its composition. The car- tridge (10 micron) removes sand, silt, dirt, other sedi- ments, and up to the ppm of chlorine shown in the specifications from the feed water (page 18). Chlo- rine will destroy the RO membrane. Filtered, clean, chlorine- free water flows from the prefilter, to the RO membrane cartridge.

IMPORTANT: See pref!lter maintenance, page 14.

REVERSE OSMOSIS (RO) CARTRIDGE

The RO cartridge is a tightly wound special mem- brane. The membrane removes the dissolved solids

and organic matter when water is forced through the cartridge. High quality product water (about one ounce per minute) exits the RO cartridge and goes to the storage tank, or to the postfilter and RO faucet.

Reject water, with the dissolved solids and organic matter, is routed through the flow control and to the drain.

STORAGE TANK

The storage tank holds up to 2.3 gallons of product water. A diaphragm inside the tank keeps water pressurized to about 30 psi, when the tank is full, to provide fast flow to the RO faucet. The tank, when empty, is pressurized to 5 - 7 psi.

POST FILTER

After leaving the storage tank, but before going to the RO faucet, product water goes through the post filter. The post filter is an activated carbon type filter. Any remaining tastes and odors are removed from the

product water. Taste-free, odor-free, clean, high quality drinking water is available for use.

FAUCET

The sink or countertop faucet has a hand operated knob to access drinking water. An air-gap is built into the faucet drain water connection to comply with plumbing codes.

FAUCET ELECTRONICS (UltraFilter 350)

The RO system will monitor the length of time the fil- ters have been installed. The faucet has an indicator

light that flashes to inform you of the status of the fil- ters.

Green - Filters are good. Red - Filters need to be re- placed after 6 months of time has passed.

SHUTOFF ASSEMBLY

To conserve water, the drinking water system has an automatic shutoff system. When the storage tank has filled to capacity, and the drinking water faucet is closed, pressure closes the shutoff to stop flow to drain. Pressure in the storage tank is about half of the water supply pressure. After drinking water is used, and pressure in the system drops, the shutoff opens to allow water flow again.

CHECK VALVE

A check valve (Figure 16) is located in the RO man- ifold, above the center sump. The check valve pre- vents a backward flow of product water from the storage tank. A backward flow could rupture the RO membrane.

FLOW CONTROL

Water flow through the RO membrane is regulated by the flow control. It maintains the desired flow rate to obtain the highest quality drinking water. The flow control is located in the end of the 1 / 4" red drain

tubing, at the RO manifold drain port.

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 (soft water is rec- ommended) helps to assure longer life from the RO membrane cartridge, prefilter and postfilter car- tridges. However, each of these will wear out in time and need replacement.

This reverse osmosis system contains a replace- able treatment component critical for effective removal of total dissolved solids. The monitor

faucet feature provides continuous analysis of the systems performance. For systems not equipped with the monitor faucet function, it is highly recommended that you have your water tested at least every 6 months to verify your system is performing properly. Test kits are available by calling 1-800-826-8553 ext. 47, or check the water testing section of your local phone directory.

If the RO assembly is wall mounted, you may be able to replace parts with the assembly left on the wall. If not, simply lift the RO assembly from the mounting washers and lay on the cabinet floor when replacing

the prefilter and post filter cartridges and RO mem- brane.

Note: To prevent spillage, place a container under the

RO assembly, or put the RO assembly in a container to catch the water.

CAUTION: Before disconnecting parts, be sure to close the water supply valve to the RO.

PREFILTER AND POST FILTER CARTRIDGES

You must replace the pref!lter cartridge often to pro- tect the RO membrane from being destroyed by chlorine, and/or from plugging with sediments in your water supply. If the water supply contains both chlorine and sediments, replace the prefilter cartridge at least every 6 months of product water use. Replace more often than 6 months if it begins to plug with sedi- ments.

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, re-

timer. (monitor models).

*Note: Use a lubricant approved for use on a potable water supply.

Figure 12

RO MEMBRANE CARTRIDGE

The life of the RO membrane cartridge depends mostly on the pH of the supply water to the RO sys- tem (see specifications). Cartridge life is shorter with higher pH. For example, if supply water pH is flom 6.8 to 7.7, the cartridge may last for well over one yea1: How- eve_, 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 RO cartridge when the pro- duction rate and/or quality of product water drops. Product water may begin to taste different or bad, in- dicating solids and organics are passing through the RO membrane. To be sure it is the RO cartridge, re- place the prefilter and postfilter cartridges first.

To replace the RO cartridge (see Figure 12):

1.Turn off the water supply and open the RO faucet to relieve pressure.

2.Remove (turn to the left) the sump from the filter

head. Be careful...the sump is full of water.

3. Remove and discard the RO cartridge in a proper manner. Flush the insides of the sump with fresh wa- ter. Do not lose the large o-ring seals.

Note: Sanitizing is recommended after servicing in- ner parts of the system (see page 11).

4.Insert new RO cartridges with o-ring seals to- wards the top, and with lubricated o-ring in place, turn to the right to reattach the sump.

5.Remove and replace batteries to reset counter and timer. (monitor models).

6.Pu_ige the RO membrane cartridge following instruc- tions on page 11.

FLOW CONTROL

The flow control is vital for proper operation of the RO membrane cartridge. The control keeps water flow through the membrane at the needed rate to ob- tain the best quality product water.

Periodically check the flow control to be sure the small hole through it is clean and unrestricted.
