Install RO Drain Under Sink

INTRODUCTION

A suitable drain point is needed for the drain water from the Reverse Osmosis Filter. You have two options to choose from:

• Install the Drain Adapter included with your unitSee Fig 7, Fig. 8, and Fig. 9. This is used in under the sink installations. The drain adapter kit is installed onto your sink drain pipe above the P-trap. See Fig. 7.

Under the Sink Installation
FIG. 7

FIG. 8

Locate drain adapter so that when the black drain tube from the Reverse Osmosis Faucet is installed it will run straight to the adapter, with no dips, loops, or kinks.
FIG. 9

• Use another existing drain in your home(See Fig 10 & 11) This is usually used in remote location type installations. The drain tube from the Reverse Osmosis Filter runs directly to an opendrain. See Fig. 10 & 11.

NOTE: An incorrectly connected drain point cancause water to leak from the faucet's air gap. FIG. 7

NOTE: Local code may dictate which type of drain installation is used. Other than local code, either drain install type may be used in both under the sink or remote location installations. Consult a plumber if you are not familiar with plumbing procedures.

INSTALL DRAIN ADAPTER KIT (Under sink Installation)

A drain adapter kit is included in your package. Review the drain adapter kit parts in Fig. 8. Install the drain adapter above or ahead of the P-trap. See Fig. 7 & 9. Be sure to comply with your local plumbing codes. The drain adapter fits 1-1/2" sink drain pipes. Other drain pipe fittings, purchased locally, may be needed in addition to the adapter.

1. Slowly disassemble the sink drain pipe between thesink P-trap and the sink tailpiece. See Fig. 7 & 9.
2. Clean the sink tailpiece to assure a leak-tight fit.
3. Install drain adapter directly onto the sink tailpieceusing the ferrule and nut. Snug the nut, but do not tighten. See Fig. 8.
4. Assemble the drain tubing connector to the drainadapter using the ferrule and nut. Snug the nut, but do not tighten. See Fig. 8.
   NOTE: Locate so that the drain tubing from the Reverse Osmosis faucet will run straight to the adapter, with no dips, loops, or kinks. See Fig. 9.
5. Turn the connector to about 45° (10:00 or 2:00position). See Fig. 8. Tighten the nut securely.
6. Assemble the P-trap to the drain adapter, and otherdrain pipe fittings as required to complete the drain run. See Fig. 7.
   NOTE: If needed, you can cut the unthreaded end of the adapter to make it fit. Do not cut too short or the adapter will not make a leak-tight seal with the connecting fitting.
7. Tighten all connections, but do not over tighten plastic connections.

Install RO Drain in Remote Location

Remote Installation Location

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.
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.

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 thedrain 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" redtubing 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 28. Leave this fitting in place.
4. Route the tubing to the drain point and secure at theend 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.

Install RO Filter Assembly

INSTALL REVERSE OSMOSIS FILTER ASSEMBLY

The Reverse Osmosis Filter Assembly is mounted on Screw (2) 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.

1. Remove the cover.
2. Locate mounting slots on back inside of the assembly. See Fig 12.
3. Hold the assembly up to the wall surface and marklocations 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 thescrews provided.
5. Hang assembly on washers.
6. Replace cover.

Install Storage Tank

1. Apply thread sealing tape (2 wraps clockwise) to the threads on the nipple at the top of the tank. See Fig 13.
2. Locate the tubing connector. See Fig. 13. Slowly tighten the tubing connector onto the tank nipple 7-8 full turns, so as not to cross thread or overtighten.
   
   FIG. 13
3. Do not connect the tube at this time. This will occur later in the assembly.
4. Place the storage tank next to the Reverse Osmosis Assembly. The tank can be placed upright or on its side.

Install RO Faucet

SELECT LOCATION OF REVERSE OSMOSIS FAUCET MOUNTING HOLE

You will need to select the location of the Reverse Osmosis Faucet. You have three options to choose from:

• Use the existing sink top hole for the spray hoseor soap dispenser (Must be 1-3/8" 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 yourReverse Osmosis Faucet.
2. Check to ensure the Reverse Osmosis faucet willmount flat against the mounting surface.
3. Visually review the routing of the tubes from theReverse Osmosis filter assembly to the faucet. Check to ensure there is adequate tube routing
4. If drilling is needed, drill a 1-3/8" diameter hole in the mounting surface.

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.

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 the person installing or servicing the system have clean hands while handling inner parts of the system. Complete the following steps to sanitize the system. See Fig. 24.

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 the eyedropper included in parts bag 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.

PRESSURE TEST THE SYSTEM

NOTE: Complete the sanitizing procedures 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. Inabout 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.

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

FIG. 25

NOTE: Codes in the state of Massachusetts require installation by a licensed plumber and do not permit the use of saddle valves.
If you live in the state of Massachusetts, review plumbing code 248-CMR of the Commonwealth of Massachusetts before proceeding with the installation.

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

Reverse Osmosis Water Flow Schematic
FIG. 26

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. 26. 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. 26. 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. 26. 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. 26. 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. 26. An air-gap is built into the faucet drain water connection to comply with plumbing codes.

Faucet Electronics: Inside the faucet base is a battery operated 6 month timer. See Fig. 15. An amber LED indicator is located in the front of the faucet base. This LED will flash continuously after 6 months have passed. This indicates that it is time to replace the battery, prefilter and postfilter.

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. 26.

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. 26.

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. 26.

Water Flow Description

1. Water enters prefilter. Sand, silt and other sediments are reduced. Chlorine is also reduced. See Fig. 26.
2. Water leaves prefilter and proceeds to the Reverse Osmosis Cartridge.
3. Water enters the Reverse Osmosis membrane. Dissolved solids are reduced.
4. Processed water leaves the Reverse Osmosis Membrane and flows to the storage tank.
5. Drain water with dissolved solids leaves the Reverse Osmosis membrane and flows to the drain.
6. Faucet is activated.
7. Processed water leaves the storage tank and flows to the postfilter, where it is filtered to ensure fresh taste.
8. Water flows to the Reverse Osmosis faucet.

Maintenance

PREFILTER / POSTFILTER MAINTENANCE

NOTE: It is recommended to replace the battery, prefilter and postfilter cartridges at least every 6 months of product water use. Replace more often if they begin to plug with sediment.

FIG. 27

The prefilter and postfilter are replaceable sediment cartridges with activated carbon in their composition. See Fig. 27. 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. 27. 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.
7. Purge the Reverse Osmosis system.

PREFILTER / POSTFILTER 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 the prefilter cartridge (turn to the left) from the filter head. Then remove the postfilter cartridge.
2. Discard the cartridges in a proper manner.
3. Install new cartridges in reverse order (postfilter first, then prefilter). Turn cartridges to the right to reattach to the filter heads. Do not overtighten.
4. Remove and replace the timer battery.
5. Purge the Reverse Osmosis system.

FLOW CONTROL

The flow control is required for proper operation of the Reverse Osmosis system. See Fig. 28. 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. 28. 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.

FIG. 28

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. 29 & 30.
2. Clean collet port, lubricate with silicone-based lubricant, and insert the o-ring seal into the bottom of the port. See Figs. 29 & 30.
3. Push the collet inward until it locks in place. See Figs. 29 & 30.

CHANGE BATTERY

To change battery, complete the following steps.

1. Remove the screw on the right side of the faucet base. See Fig. 31.
2. Press the battery housing upwards from the front faucet base until it releases from the faucet base. See Fig. 31.
3. Replace the battery (CR 2032 or equivalent). Place battery into the holder with the positive (+) side facing the back of the holder.
4. When the battery is installed the LED will flash six times and turn off. This indicates the battery is fully charged. After the six flashes, the timer enters the 6 month time cycle. If it repeatedly flashes two times, it is not a fully charged battery.
5. Re-install the battery housing and firmly tighten the mounting screw. See Fig. 31.

Troubleshooting

Problem: Chlorine taste and/or odor in the RO product water.
Cause: The level of chlorine in your water supply exceeds maximum limits, and has destroyed the Reverse Osmosis membrane.	Correction: If the water supply contains more than 2.0 ppm of chlorine, additional filtering of the water supply to the Reverse Osmosis is needed. Contact your local water supplier. Correct this condition before doing maintenance on the Reverse Osmosis system.
Cause: The prefilter is no longer reducing chlorine from the water supply.	Correction: Replace the prefilter, postfilter and Reverse Osmosis membrane cartridges.
Problem: Other taste and/or odor.
Cause: Postfilter expended. Cause: Reverse Osmosis membrane cartridge expended.	Correction: Replace the postfilter cartridge. If taste and odor persist, replace the prefilter cartridge and Reverse Osmosis membrane cartridge.
Cause: Contamination in product water storage tank.	Correction: Use sanitizing procedures. Replace prefilter and postfilter cartridges.
Cause: System contamination.	Correction: Sanitize entire system. Call 1-866-986-3223 for instructions.
Problem: System makes product water too slowly.
Cause: Water supply to the Reverse Osmosis system not within specifications.	Correction: Increase water pressure, precondition the water, etc., as needed to conform before doing maintenance on the Reverse Osmosis system.
Cause: Prefilter or Reverse Osmosis membrane cartridges plugged with sediment.	Correction: Replace the prefilter cartridge. If rate does not increase, replace the postfilter cartridge and Reverse Osmosis membrane cartridge.
Problem: System makes lower amount of product water than usual.
Cause: Storage tank air-charge less than 5-7 psi.	Correction: Open Reverse Osmosis faucet and drain tank until flow slows to a drip. Keep faucet open and check tank pressure. If low, pressurize to 6 psi. Close faucet to refill the tank.
Problem: High total dissolved solids (TDS) in product water.
Cause: Water supply to the Reverse Osmosis system not within specifications.	Correction: Increase water pressure, precondition the water, etc., as needed to conform before doing maintenance on the Reverse Osmosis system. Correction: Send treated and untreated water samples to a water analysis lab for testing. It is important to test both the treated and untreated water to determine system performance. If the TDS is not within the system's performance guidelines, replace the prefilter, post filter and RO membrane cartridges.
Cause: Plugged drain flow control insert.	Correction: Replace drain flow control insert.
Problem: Continual water flow to drain and low or no water production.
Cause: Missing flow control insert in drain port.	Correction: Make sure flow control insert is in place.
Problem: Water leaking from faucet airgap hole.
Cause: Drain side of faucet airgap (3/8" black tubing) plugged, restricted or incorrectly connected to drain point.	Correction: Inspect and eliminate restriction or plug. Check that drain line is routed properly. Refer to installation instructions for proper drain connection.
Problem: Faucet LED indicator light does not function after battery change.
Cause: Battery dead.	Correction: Replace with new battery.
Cause: Battery installed incorrectly.	Correction: Install battery correctly.
Problem: Water leaks at push connect fittings.
Cause: Tubing not cut square.	Correction: Cut tubing square.
Cause: Tubing not pushed in all the way.	Correction: Push tubing in all the way.
Cause: Tubing nicked.	Correction: Remove tube from connection. Remove nicked portion by cutting tube to shorter length. Reinsert in connection. If removing the drain line, leave in place the elbow fitting that it connects to.
Cause: Outer tubing surface finish not smooth.	Correction: Remove tube from connection. Remove problem area by cutting tube to shorter length. Reinsert in connection. If removing the drain line, leave in place the elbow fitting that it connects to.
