Step B - Install RO Drain Under Sink

INTRODUCTION

A suitable drain point is needed for the drain water from

he Reverse Osmosis filter. You have two options:

• Install the Drain Adaptor included with your unit

As shown in Figures 7-9, the drain adaptor is

nstalled onto your sink’s drain pipe above the P-trap.

i This is normally used for under sink installations.

• Use another existing drain in your home

As shown in Figures 10 and 11, the drain tube from the RO filter runs directly to an open drain. This is often used for remote location installations.

NOTE: An incorrectly connected drain point can cause water to leak from the faucet’s air gap.

NOTE: Local code may restrict the type of drain installation to use. Either drain installation type, if permitted by code, may be used in under sink or remote location installations. Consult a plumber if you are not familiar with plumbing procedures.

INSTALL DRAIN ADAPTOR

(Under sink Installation)

The drain adaptor included with your RO system is designed to fit around a standard 1-1/2” O.D. drain pipe. In the following procedure, you will install the drain adaptor above (upstream of) the P-trap. See Fig. 7 & 9. Be sure to comply with local plumbing codes.

NOTE: Before starting this procedure, inspect the drain pipe under the sink for corrosion, and replace if necessary, before continuing with installation.

1. Test fit the two halves of the drain adaptor onto the sink drain pipe, about 6 inches above the P-trap (See Fig. 8). Make sure that the Q.C. fitting is toward the direction of the RO faucet (See Fig. 9).

NOTE: Locate so that the drain tubing from the Reverse Osmosis faucet will run straight to the adaptor, with no dips, loops, or kinks.

2. Using the hole through the drain fitting as a guide, mark the pipe where a 3/8” hole will be drilled (See Fig. 8), and remove the drain adaptor from the pipe.

NOTE: Do not drill through the drain adaptor’s Q.C. fitting, as this could damage the o-ring.

3. Drill a 3/8” dia. hole in the pipe and remove flash.

4. Clean the sink tailpiece to assure a leak-tight fit.

5. Place the halves of the drain fitting back onto the

sink drain pipe. Use a pencil or similar pointed object to align the Q.C. fitting so that it is centered on the hole you drilled.

6. Assemble the nuts and screws, as shown in Figure 8, and tighten both sides equally to secure the drain adaptor halves onto the pipe. Do not overtighten.

7. Do not connect black tubing to the Q.C. fitting at this time. It is done after the RO faucet is installed.

INSTALL A REMOTE DRAIN POINT AND AIR GAP (Remote Location)

Route the drain tubing to an existing drain in the house. A floor drain, laundry tub, standpipe, sump, etc. are suitable drain points. See Fig. 11. This type of drain is the preferred over the p-trap drain adapter. Always be sure to provide a 1-1/2” air gap between the end of the hose and the drain point. This will prevent water from backing up into the system.

NOTE: Check your local plumbing codes.

Telephone cable extension must consist of a male connector on one end and a female connector on the other to keep proper polarity. Polarity may be reversed if a coupler is used and monitor will not work.

Floor Drain

FIG. 11

To install a remote drain point, complete the following steps:

1. Locate the 1/4” red tubing on the Reverse Osmosis filter assembly. See Fig. 10.

2. Determine if this length is long enough to reach the drain point. Longer lengths of tubing (see parts list in back of manual) may be needed.

3. If longer tubing is required, disconnect the 1/4” red tubing and replace with an adequate length of tubing to reach the drain point. Refer to Step F later in the manual on how to disconnect and connect tubing.

NOTE: A flow control insert is located inside the elbow fitting that the drain tube connects to. Refer to Fig. 29. Leave this fitting in place.

4. Route the tubing to the drain point and secure at the end with a bracket (not included). See Fig. 11. Provide a 1-1/2” air gap between the end of the tube and the drain. See Fig. 11.

Step C - Install RO Filter Assembly

INSTALL REVERSE OSMOSIS FILTER ASSEMBLY

he Reverse Osmosis Filter Assembly is mounted on

T hanger washers.

See Fig 12. The hanger washers allow you to lift the filter assembly from the washers without any hardware removal. When planning your installation, you need to leave room for changing filters.

Complete the following steps to install your Reverse Osmosis Filter Assembly:

1. Remove the cover.

2. Locate mounting slots on back inside of the assem-

bly. See Fig 12.

3. Hold the assembly up to the wall surface and mark locations for the hanger washers. See Fig 12. Mount the unit high enough to allow room to change filters without taking the unit off of the wall.

4. Fasten the hanger washers to the wall using the screws provided.

5. Hang assembly on washers.

6. Replace cover.

Step E - Install RO Faucet

SELECT LOCATION OF REVERSE OSMOSIS FAUCET MOUNTING HOLE

ou will need to select the location of the Reverse

Y Osmosis Faucet. You have three options to choose from:

• Use the existing sink top hole for the spray hose

or soap dispenser (Must be 1-1/4” in diameter)

• Drill a new hole in the sink

• Drill a new hole in the countertop next to the sink

1. Determine where you are going to install your

Reverse Osmosis Faucet.

2. Check to ensure the Reverse Osmosis faucet will mount flat against the mounting surface.

3. Visually review the routing of the tubes from the Reverse Osmosis filter assembly to the faucet. Check to ensure there is adequate tube routing space between the faucet and filter assembly.

4. If drilling is needed, drill a 1-1/4" diameter hole in the mounting surface.

IMPORTANT: Drilling holes into countertops and sinks should only be performed by an installer who is qualified for drilling such materials. Drilling of surfaces made of stone or solid surface materials such as granite, marble, Corian™ or other plastic resin products or sinks made of porcelain or stainless steel may cause permanent, irreparable damage to the sink or countertop surface.

INSTALL BATTERY

When the coin battery is first applied at initial start up, the LED indicator light will flash in red, amber, green sequence. All timers and counters are reset to zero. In order to reset the time and gallon count feature, push the button on the PWA and hold until the LED flashes and release.

The battery needs to be replaced at the time of filter replacement. Use only lithium batteries (CR 2032 or equivalent). Use care when inserting the battery to align it correctly on the PWA with the proper polarity. Improper placement of battery could damage electronics.

Step F - Connect Tubes

HOW TO CUT AND CONNECT THE TUBES

Your Reverse Osmosis system includes push-in fittings for quick tubing connection. Review the following instructions before connecting the tubes in the next step. Failure to follow these instructions may lead to future leaks.

Cut tubes to length

1. Use a sharp cutter or knife to cut the end of tubing.

Always cut the tubing square. See Fig. 18.

2. Inspect the tube up to 1” from the end to be sure there are no nicks, scratches or other rough spots. If needed, cut the tubing again. See Fig. 18.

Connect tubes

NOTE: Remove foam plugs before connecting tubes (See Fig. 17). Discard foam plugs.

1. Push tubing through collet, until it engages the oring. See Fig. 19. Continue pushing until the tube bottoms out against the back of the fitting. See Fig.

20. Do not stop pushing when the tube engages the o-ring. Failure to follow these instructions may lead to future leaks. When a 1/4” tube is fully engaged, 11/16” of the tube has entered the fitting. When a 3/8” tube is fully engaged, 3/4” of the tube has entered the fitting. Mark tube with a piece of tape or marker. See Figs. 19 & 20.

2. If additional tubing is required, see parts list at the end of this manual.

Step G - Sanitize, Test and Purge System

SANITIZE THE SYSTEM

Sanitizing is recommended immediately after installation of the Reverse Osmosis system. It’s also recommended after servicing inner parts. It is important that

he person installing or servicing the system have

t clean hands while handling inner parts of the system.

Complete the following steps to sanitize the system. See Fig. 24.

1. Make sure that the water supply to the Reverse Osmosis system is off.

2. Open the Reverse Osmosis faucet. If the tank is not already empty, allow the water to empty.

3. Locate an eyedropper and common household bleach (5.25%).

4. Add 3 ml. of bleach into open end of yellow tubing. Handle bleach according to bleach manufacturer’s recommendations. See Fig. 24.

5. Connect yellow tubing to tank connector. See Figs. 13 and 24.

6. Sanitizing the system will be completed during the pressure test and purging steps on the following page.

NOTE: The bleach must be removed from the system before drinking the water. See purging instructions on the next page.

Step G - Sanitize, Test and Purge System (cont.)

PRESSURE TEST THE SYSTEM

NOTE: Complete the sanitizing procedures on the preceding page before pressure testing.

To pressure test the system, complete the following steps.

1. Open the water supply valve to the Reverse Osmosis system.

2. Purge air from the house plumbing by opening several house faucets. Close faucets when water runs smooth, with no spurting.

3. Pressure will start to build in the RO system. In about 2 hours check all fittings and connections. Check for water leaks. Fix leaks if any are found. If problems exist, refer to the troubleshooting chart or call the toll free number below).

NOTE: When the system is first pressurized, water may ''spurt'' from the faucet air gap hole until air is expelled from the RO system.

Please review the following operating features before using your Reverse Osmosis system:

You will not have filtered water immediately. It may take several hours to fill the storage tank and create maximum flow from the Reverse Osmosis faucet.

Water Pressure from the Reverse Osmosis faucet will be less than your standard faucet.

Water will run to the drain while the Reverse Osmosis system is producing water, even if you are not drawing water from the Reverse Osmosis faucet. You may hear a small quantity of water going to the drain at times when water is not being used. This is normal. Water going to the drain will automatically shut off when the storage tank is full.

PURGING THE SYSTEM

To purge the system, complete the following steps.

1. Open the Reverse Osmosis Faucet and let water flow through the system for a 24 hour period. Water flow will be a slow trickle at this time.

NOTE: Do not consume water from the RO system until purging is complete.

2. Close the Reverse Osmosis faucet after the 24 hour purging period is complete.

3. When the purging is finished, your Reverse Osmosis system is ready for use.

NOTE: As with all other water system applications, leaks may occur. Because the system pressure builds slowly, leaks may not be immediately apparent. Recheck for leaks 24 hours after purging the system is complete.

How Your RO Water System Works

HOW YOUR REVERSE OSMOSIS SYSTEM WORKS

Introduction: Your Reverse Osmosis (RO) Drinking

Water System uses your household water pressure to force water through three filters. Minerals and impurities are filtered out. Delicious tasting drinking water goes to the storage tank-ready for your use. Minerals and impurities are sent down the drain. The following paragraphs will explain in detail how your Reverse Osmosis Drinking Water System works.

Prefilter: Water from the cold supply pipe enters the prefilter. See Fig. 27. The prefilter is a replaceable sediment cartridge with activated carbon in its composition. The cartridge reduces taste, odor, sand, silt, dirt, other sediments, and up to the amount of chlorine shown in the specifications.

Reverse Osmosis Cartridge: Filtered water flows from the prefilter to the Reverse Osmosis membrane cartridge. See Fig. 27. The Reverse Osmosis cartridge is a tightly wound special membrane. The membrane reduces the dissolved solids and organic matter. High quality product water (about one ounce per minute) exits the Reverse Osmosis cartridge. The product water flows to the storage tank, postfilter or Reverse Osmosis faucet. Drain water, with the dissolved solids and organic matter, is routed to the drain.

Storage Tank: The storage tank holds product water. See Fig. 27. A diaphragm inside the tank holds water pressurized to about half of supply water pressure when the tank is full. This provides fast flow to the Reverse Osmosis faucet. When the tank is empty of water, the pressure at the air valve is 5 - 7 psi.

Postfilter: Water goes through the postfilter before going to the Reverse Osmosis faucet. See Fig. 27. The postfilter is an activated carbon type filter. Any remaining tastes and odors are reduced from the product water. Clean, high quality drinking water is available at the faucet.

Reverse Osmosis Faucet: The sink or countertop faucet has a hand operated knob to dispense drinking water. See Fig. 27. An air-gap is built into the faucet drain water connection to comply with plumbing codes.

Faucet Electronics: The RO system will monitor the total flow of the unit and also length of time the filters have been installed. The faucet base has an indicator light that flashes to inform you of the status of the RO membrane and filters.

Green - RO membrane and filters are good.

Reset Button

PWA Board

FIG. 26

Amber - Warning, filters need replacing. Filters

need replacing after 6 months during which water has been drawn (or 750 gallons have been used).

Red - RO membrane needs to be replaced.

When the coin battery is first applied at initial start up, the LED indicator light will flash in a red, amber, green sequence. All timers and counters are reset to zero. In order to reset the time and gallon count feature, push the button on the PWA and hold until the LED flashes and release. The battery needs to be replaced at the time of filter replacement. Use only lithium batteries (CR 2032 or equivalent). Improper placement of battery could damage electronics. Use care when inserting battery to align it correctly on PWA with the proper polarity.

Shutoff Assembly: The unit has an automatic shutoff system to conserve water. When the storage tank has filled to capacity, and the drinking water faucet is closed, pressure closes the shutoff to stop flow to the drain. After enough drinking water is used, pressure in the system drops, and the shutoff opens to allow the tank to be refilled. See Fig. 27.

Check Valve: A check valve is located in the Reverse Osmosis manifold above the center cartridge. The check valve prevents a backward flow of product water from the storage tank to drain. A backward flow could damage the Reverse Osmosis Membrane. See Fig. 27.

Flow Control: Water flow to the drain is restricted by the flow control. It maintains the desired flow rate to obtain the highest quality drinking water. The flow control is located inside the elbow fitting on the Reverse Osmosis manifold drain port. See Fig. 27.

Maintenance

PREFILTER / POSTFILTER MAINTENANCE

NOTE: It is recommended to replace the battery,

refilter and postfilter cartridges at least every 6

p months of product water use. Replace more often if they begin to plug with sediment.

he prefilter and postfilter are replaceable sediment

T cartridges with activated carbon in their composition. See Fig. 28. You must periodically replace the prefilter and postfilter cartridge. This will protect the RO membrane from being destroyed by chlorine. It will also prevent the filters from plugging with sediment.

You may notice a slower output of product water as the prefilter and postfilter build up with sediment. Replace the prefilter and postfilter cartridges when this occurs. You should replace the battery whenever you replace the cartridges.

RO MEMBRANE CARTRIDGE MAINTENANCE

The Reverse Osmosis cartridge is a tightly wound special membrane. See Fig. 28. The membrane reduces the dissolved solids and organic matter. The life of the Reverse Osmosis membrane cartridge depends mostly on the pH and hardness of the supply water (see Specifications). Cartridge life is shorter with higher pH. For example, if supply water pH is from 6.8 to 7.7, the cartridge may last for well over one year. However, 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 Reverse Osmosis cartridge when the production rate and/or quality of product water drops. Product water may begin to taste different, indicating solids and organics are passing through the Reverse Osmosis membrane. See Reverse Osmosis cartridge replacement.

REVERSE OSMOSIS CARTRIDGE REPLACEMENT

Complete the following steps to replace the cartridges.

NOTE: Do not remove manifold from mounts. Flexing or twisting may damage the manifold.

1. Remove (turn to the left) the prefilter cartridge from the manifold to stop flow to the Reverse Osmosis cartridge.

2. Remove the Reverse Osmosis cartridge.

3. Remove the postfilter cartridge.

4. Discard the cartridges in a proper manner.

5. Install new cartridges in reverse order (post filter,

Reverse Osmosis and then prefilter). Turn cartridges to the right to reattach to the filter heads. Do not overtighten.

6. Remove and replace the timer battery. See page 12.

7. Press and hold the button on the electronics board

(PWA) until the green light begins flashing. Release the button as soon as the light begins flashing (the light flashes for 3 seconds and releasing the button before or after that 3 seconds will not reset the elec-

Maintenance

FLOW CONTROL

The flow control is required for proper operation of the Reverse Osmosis system. See Fig. 29. The flow control, located inside the push-in elbow fitting on the drain port of the system housing, keeps water flowing through the membrane at the required rate. This ensures that the system produces the best quality product water.

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

If the flow control requires service, review the exploded view in Fig. 29. Assemble and disassemble as shown. If the flow control remains in the manifold when the push-in elbow fitting is removed, you will need to remove the drain port’s collet and o-ring, as shown in the next section, to retrieve it.

CHANGE COLLET AND O-RING

1. Remove the collet and o-ring from the fitting with a small

screwdriver. Do not scratch the internal walls of the collet port. See Figs. 30 & 31.

2. Clean collet port, lubricate with silicone-based lubricant, and insert the o-ring seal into the bottom of the port. See Figs. 30 & 31.

3. Push the collet inward until it locks in place. See Figs. 30 & 31.

Performance Data

Reverse Osmosis Filter System Model NSRO42C4

IMPORTANT NOTICE: Read this performance data and compare the capabilities of this unit with your actual water treatment needs. It is recommended that, before purchasing a water treatment unit, you have your water supply tested to determine your actual water treatment needs. This filter system is designed to be used for the reduction of the substances listed below. Do not use where water is microbiologically unsafe or of unknown quality, without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected water that may contain filterable cysts. This system has been tested for the treatment of water containing pentavalent arsenic (also known as As (V), As (+5), or arsenate) at concentrations of 0.30 mg/L or less. This system reduces pentavalent arsenic, but may not reduce other forms of arsenic. This system shall be used on water supplies containing a detectable free chlorine residual at the system inlet or on water supplies that have been demonstrated to contain only pentavalent arsenic. Treatment with chloramine (combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic. Please see the Arsenic Facts section on page 28 for further information. While testing was performed under standard laboratory conditions, actual performance of this system may vary based on local water conditions. Some or all of the contaminants reduced by this unit may not be in your water supply. See elsewhere in this owner’s manual for further instructions on filter replacement, system installation, operating procedures, and warranty. The maintenance instructions must be followed for the product to perform as indicated below.

ARSENIC FACTS

Background

rsenic (abbreviated As) can occur naturally in well water. There are two forms of arsenic: pentavalent arsenic

A [also called As (V), As(+5), and arsenate] and trivalent arsenic [also called As (III), As(+3), and arsenite]. Although both forms are potentially harmful to human health, trivalent arsenic is considered more harmful than pentavalent arsenic. In well water, arsenic may be pentavalent, trivalent, or a combination of both. Additional information about arsenic in water can be found on the Internet at the U.S. Environmental Protection Agency (USEPA) website:www.epa.gov/safewater/arsenic.html.

Testing Your Water

Arsenic in water has no color, taste or odor. It must be measured by a lab test. Public water utilities must have their water tested for arsenic. You can get the results from your water utility. If you have your own well, you can have the water tested. The local health department or the state environmental health agency can provide a list of certified labs. The cost is typically $15 to $30.

Pentavalent vs.Trivalent Arsenic Removal

These systems are very effective at reducing pentavalent arsenic from drinking water. These models were tested in a lab and proven to reduce 300 parts per billion (ppb) pentavalent arsenic to below 10 ppb, the USEPA standard for safe drinking water.

RO systems are not as effective at reducing trivalent arsenic from water. These models will not convert trivalent arsenic to pentavalent arsenic. If you have free chlorine residual in contact with your water supply for at least one minute any trivalent arsenic will be converted to pentavalent arsenic and reduced by this RO. Other water treatment chemicals such as ozone, and potassium permanganate will also change trivalent arsenic to pentavalent arsenic. A combined chlorine residual (also called chloramine) may not convert all the trivalent arsenic. If you get your water from a public water utility, contact the utility to find out if free chlorine or combined chlorine is used in the water system.

Maintenance

It is strongly recommended that you follow the maintenance instructions and have your water tested periodically to make sure the system is performing properly. See replacement element information above for recommendations on maintaining your Reverse Osmosis drinking water treatment system.
