SAFETY GUIDES

Read all steps, guides and rules carefully before installing and using the Undercounter RO System. Follow all steps exactly to correctly install.

BE SURE TO FOLLOW APPLICABLE STATE AND LO- CAL PLUMBING AND SANITATION CODES when installing the Undercounter RO system. Using a quali-

fied installer is recommended. The Undercounter RO System works on water pres-

sures of 40 psi minimum, to 125 psi maximum (seethe table on page 3). If house water pressure is over the maximum, install a pressure reducing valve in the water suppiy line to the Undercounter RO System.

DO NOT install the Undercounter RO System outside, or in extreme hot or cold temperatures. Temperature of the water supply to the Undercounter RO System must be between 40”F (minimum) and 80 or 100°F (maximum) ...see the table on page 3. DO NOT

INSTALL ON HOT WATER.

Read the other limits (pH, water hardness, etc.), page 3, and be sure the water supply conforms.

Do not use the system on microbiologically unsafe water, or water of unknown quality.

WHAT THE UNDERCOUNTER RO SYSTEM WILL DO

The undercounter system is a REVERSE OSMOSIS (RO) water treating unit. Reverse osmosis is a way of removing dissolved solids and organic matter from water by passing it through a special membrane. The membrane separates minerals and impurities from the water, and they are

flushed to the drain. Good tasting, high quality productwater goes directly to the drinking water faucet, or tothe storage area. The system makes a good supply of drinking water each day (see specifications). How much it will make depends on the feed water supply pressure, temperature,

and quality.

The system includes an electronic faucet assembly with a

built–in water testing feature. When water is taken from the

faucet, a green indicator light means TDS removal is within specified limits, and that water quality is good.

Pre and postfilters are replaceable cartridges. The carbon prefilter removes up to 2 ppm of chlorine while also filtering sediments. The postfilter removes any other undesirable tastes and odors before you use the water.

The drinking water system fits nicely under the kitchen or bathroom sink. However, you you can install it where most convenient. You do need a COLD water supply pipe and drain point within a few feet (6’ tubing lengths included). You can buy longer lengths of tubing if needed to reach more distant points...BE SURE TUBING IS ACCEPTABLE FOR USE ON POTABLE WATER SUPPLIES.

Page 4

COMPONENTS OF THE SYSTEM

The factory assembled RO system is shippedinI carton. A parts bag includes the RO product water faucet and tubing adaptor fittings. All tubing (6 ft lengths), required for installation, is attached to the RO system. An additional 27

in. length is provided to connect between the faucet and the drain point. This electronic model also includes a package of special faucet base parts.

THINGS TO CHECK BEFORE YOU START TO INSTALL

●

FEED WATER - The water supply to the undercounter RO system must have the qualities listed in the specifications. If not, it will not make product water as it should and life of the RO membrane is shortened. City water most often will have these qualities. Well water may need conditioning. Have the water tested by a water analysis Iabatory, and get their recommendations for treatment. Observe plumbing codes when providing a water supply to the RO. A self–piercing saddle valve is included for tapping into a cold water pipe (check local codes). Refer to pages 5 and 17.

CAUTIONS:

MODEL GE/ 18- Feed water must have all chlorine

removed (prefilter removes up to 2.0 ppm). Chlorine will destroy the R

to service the prefilter at suggested intervals, page 11.

O membrane cartridge. Be sure

INSTALLER PROVIDES: The water supply valve and drain fitting (pages 5 and 6) are included for use in areas

where codes permit. Both items nwst comply with

state and/ or /oca/ codes. If not, the installer must provide, (1)fittings to tap the cold water pipe for a feed water source to the RO...must adapt to 1/4” OD tubing; and (2) a drain point for RO discharge water...must adapt to 3/8’

OD tubing.

●

DRAIN POINT - A suitable drain point (check your local codes) is needed for reject water from the RO

membrane cartridge. We suggest using the SINK P–

TRAP drain pipe. A drain clamp (drilling required) is

included to use where codes permit. Refer to pages 6 and 17.

●

RO FAUCET - The RO product water faucet installs on the sink, or on the countertop next to the sink. Often, it’s installed in an existing sink spray attachment hole. Space is required underneath for tubing to and from the faucet, and for securing it in place. All electronic faucet connections and installation procedures are done on or above the sink or countertop.

Refer to page 7 or 8.

Page 5

FEED WATER SUPPLY

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” OD tubing...see Fig. 6, page 9. A typical installation, using the included self-

tapping (into copper) saddle valve is shown in A below. An optional installation, using standard plumbing fittings, is shown in B.

A. SADDLE VALVE

NOTE: This valve will pierce a hole in copper tubing or plastic pipe. If installing on iron pipe, you have to drill a 1/8 hole for the piercing pin (READ DANGER NOTE BELOW). Be sure to turn off water to the pipe and to

drain water from it before drilling.

4. IMPORTANT PURGING INSTRUCTIONS: The RO cartridge contains a food grade presewative that you should

clean from it before using the system. The preservative will give product water an unpleasant taste and odor. After the bladder has filled (takes about 4 hours), open the system faucet until the bladder is empty. Allow the bladder to fill again for 4 hours, then open the faucet and empty. After 4 purgings, the system is ready to make product water

.for your use.

3. In about 4 hours, pressure will start to build in the RO

tubing connections for any water leaks. Correct leaks if any are found.

HOW THE UNDEI?COUNTER RO SYSTEM WORKS (FIG. 7)

PREFILTER

Water from the cold supply pipe enters the RO assembly and is directed to the prefilter cartridge.

NOTE: Before going to the prefilter, supply water first passes through the electronic box to measure total dissolved solids (TDS).

The prefilter is a replaceable sediment cartridge with acti-

vated carbon in its composition. The cartridge (5 micron) removes sand, silt, dirt, other sediments, and up to 2.0 ppm of chlorine from the feed water., CHLORINE DESTROYS THE ERO 392 MEMBRANE. Filtered, clean, chlorim+free water flows from the prefilter, to the RO membrane cartridge. IMPORTANR See prefilter main-

tenance, page 11.

REVERSE OSMOSIS (RO} CARTRIDGE

The cartridge, inside the RO housing, includes a tightly wound, special membrane. Water is forced through the cartridge where the membrane removes the dissolved solids and organic matter. High quality product water exits the RO housing and goes to the storage area. Reject water, with the dissolved solids and organic matter, leaves the housing and is discharged to the drain through 1/4” tubing.

NOTE: On electronic models, product water passes

through the electronic box before going to the faucet, to

measure total dissolved solids (TDS).

PRODUCT WATER STORAGE

The storage area holds up to 1.7 gallons of product water. The flexible bladder keeps water pressurized for fast flow to the faucet when drinking water is needed.

POSTFILTER

After leaving the storage area, but before going to the faucet, product water goes to the postillter. The postfilter is also the activated carbon type sediment filter. Any remain-

ing tastes, odors, or sediments are removed from product

water. Tast&free, odor–free, clean, high quality drinking water flows through the tubing and to the faucet.

HOW THE UNDERCOUNTER RO SYSTEM WORKS (FIG. 7)

FAUCET AND ELECTRONICS

The sink or countertop faucet vends the drinking water

when opened. it has a hand operated, spring loaded closed lever to prevent waste. You can also keep the faucet open by pushing upward on the lever and locking it against the faucet spout.

To comply with plumbing codes, an air-gap is built into the faucet drain water connection.

The electronic faucet provides a built–in water quality tester. As water is taken from the faucet, the indicator lights

show how the RO system is operating to provide high quality drinking water.

● FLASHING GREEN LIGHT - The RO system is giv-

ing you high quality drinking water.

NOTE: The green light may stop flashing when the supply of RO water is nearly gone, and flow from the RO faucet decreases. This is a normal condition.

● FLASHING RED “FILT” LIGHT - The prefilter car-

tridge and postfilter need replacing. This occurs after

6 months, or 900 gallons of product water use. Also replace the control box batteries... see page 12.

● FLASHING AMBER “RO” LIGHT - The RO car-

tridge no longer removes at least 75% of the TDS from

supply water and needs replacement.

NOTE: Disregard initial or short periods of the flashing “ROY’ light.

SHUTOFF ASSEMBLY

To conserve water, the drinking water system has an automatic shutoff assembly. When the storage tank has filled

to capacity, and the drinking water faucet is closed, pres-

sure closes the shutoff. Water flow to the RO housing is shut off until drinking water is used again, and pressure drops in the RO system.

CHECK VALVE

A check valve (Fig. 7) is buiit into the bottom end of the RO housing. The check valve prevents a backward flow of product water from the storage area. A backward flow could cause TDS to bleed into the product water, and could rupture the RO membrane.

FLOW CONTROL

The flow control (see Fig. 8) regulates flow, through the

RO cartridge, to the required rate to get the desired quality of product water. The control is located in the drain tubing, at the RO cap fitting. A small, corwshaped screen fits over the front end of the flow control to help prevent plugging with drain water sediments.

PREFILTER CARTRIDGE AND POSTFILTER RE- PLACEMENT

You must replace the prefilter cartridge often to protect the RO membrane from being destroyed by chlorine, and/or from plugging with sediments in the water

supply. Ifthe water suppl y contains both chlorine and sediments, replace the prefilter cartridge at least every-6 months, or more often if it begins to plug with sediments. If the water has sedhnents on/~ with no chlorine, you may begin to notice a slower making of product water. When this happens, a new sediment cartridge is needed. Also replace the postfilter.

To signal correct replacement interval, the red “FllT” indicator light, on the electronic faucet base, will beginto flash after6 months, or 900 gallons of product water use, which-

occurs first.

ever At the same time, replace the batteries in the control box.

Replacing the batteries resets the 6 month or 900 gallon period, and assures proper operation of the RO indicator Iight...see page 12.

tridge”, also on this page.

2. Remove and replace the flow control and

screen... see below.

3. Turn on the water supply and PURGE THE RO CAR-

TRIDGE...SEE PAGE 9.

BAITERIES IN ELECTRONIC CONTROL BOX Always replace the 4, “AA” alkaline batteries in the control

box when changing the prefilter cartridge and postfilter. Good batteries are needed to assure proper indicator light operation. Weak batteries may give a false indication. Changing the batteries also resets the 6 month or 900 gallon period.

3. Lift the RO cartridge and prefilter cartridge from the ‘housing. Separate and dispose of the prefilter car-

tridge.

4. Dump water from the RO housing.

5. Slide the RO cartridge INTO THE TOP END of the new prefilter cartridge, as shown in Fig. 8. Then, place into the RO housing.

NOTE: Be sure the bottom end of the prefilter is at the

bottom, and the UP arrow on the RO cartridge points

upward.

6. Lubricate the cap o-ring seal (silicone grease). Then,

push the cap into position and install the clamp sections and retainers.

RO CARTRIDGE

The life of the RO cartridge depends mostly on the pH of

properly treated feed water... see pages 3 and 4. The higher the pH, the shorter cartridge life is. For example, if feed

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 8.0 or 10 (see specifica-

tions). The higher pH weakens the cartridge membrane

and makes pin–hole leaks.

FLOW CONTROL AND SCREEN

The flow control is vital for proper operation of the RO cartridge. The control must keep water flow through the cartridge at the proper rate to obtain the best quality product water.

When servicing the RO, it’s good practice to check the

flow control (and tubing to it) to make sure the small tube

and surrounding surfaces are clean and unrestricted. A small, cone-shaped screen (Fig. 8) is located in front of

the flow control to help keep it clean. If the flow control

should plug with foreign particles, the RO cartridge cannot discharge minerals and impurities to the drain. If this should happen, it will only take a short time for the cartridge to plug, making it useless.

CAUTIONS:

To install the screen, place the cone end into the RO cap. Then, carefully push it in using l/4’’ tubing as a tool. Do not force in farther after you feel resistance. Visually check to be sure it is properly positioned.

When installing the flow control, tighten the tubing nut by

hand, then another 1/4 to 1/2 turn with a pliers. DO NOT

OVERTIGHTEN AND DISTORT OR CRUSH THE TUB-

ING AND FLOW CONTROL.
