• The water pressure from the Reverse Osmosis faucet will be less
  than your standard faucet due to the high level of filtration
  performed by the system.

• The faucet can be mounted in an existing hole in the sink
  (sprayer, soap dispenser, etc.) or a new hole can be drilled.

• Water will run to the drain while the Reverse Osmosis system is
  producing purified water, even if you are not drawing water from
  the faucet.

• You may hear a small quantity of water going to the drain
  whenever the system is producing purified water. Water going to the
  drain will automatically shut off when the storage tank is
  full.

Performance Data
Reverse Osmosis Filter System – Model WHAROS5
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 8 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.
General Information This product is an undercounter system that filters and stores quality drinking water ready for use. It contains a carbon sediment filter, RO membrane, and an activated carbon post filter. The faucet indicator monitors the length of time the filter has been installed and will flash amber continuously; indicating the filters and battery need to be replaced. This system has been tested according to NSF/ANSI 58 and 42 for reduction of substances listed below. The concentration of the indicated substances in water entering the systems were reduced to a concentration less than or equal to the permissible limit for water leaving the system, as specified in NSF/ANSI 58.

Performance Data
ARSENIC FACTS
Background
Arsenic (abbreviated As) can occur naturally in well water. There are two forms of arsenic: pentavalent arsenic [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 water filtration system.

Step A – Install Cold Water Supply Fitting

CHOOSE TYPE OF WATER FITTING TO INSTALL
Check and comply with local plumbing codes as you plan, then install a cold water supply fitting. Refer to the Specifications page for supply water requirements. The fitting must provide a leak-tight connection to the RO 1/4″ tubing. A typical connection using the included water supply fitting is shown in Figure 6.. An optional connection using standard plumbing fittings (not included) is shown in Figure 7.
NOTE: Local code may dictate which type of water fitting is used. Consult a plumber if you are not familiar with local codes or plumbing procedures.
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.
INSTALL COLD WATER SUPPLY FITTING (Included)
This fitting will be installed on the cold water pipe. The fitting must provide a leak-tight connection to the Reverse Osmosis 1/4″ tubing. Locate the cold water line in the sink cabinet. It is recommended, but not required, that the cold water line be soft water.
Complete the following steps to install the water supply fitting.
1. Close the water shutoff valve (angle stop valve) that the water supply fitting will be installed on, and open faucet(s) to relieve pressure.
2. Disconnect the existing cold water line from the water shutoff valve.
3. Make sure that the water supply fitting’s gasket is inside the female threaded portion of the fitting.
4. Install the water supply fitting onto the cold water shutoff valve, where the existing cold water line was removed, and hand tighten. Be sure not to cross thread or overtighten.
5. Connect the existing cold water line to the male threaded portion of the water supply fitting and hand tighten. Be sure not to cross thread or overtighten.
OPTIONAL PIPE FITTINGS (compression type shown)
NOTE: Be sure to turn off the water supply and open a faucet to drain the pipe.
Complying with plumbing codes, install a fitting on the cold water pipe to adapt 1/4″ OD tubing. A typical connection is shown in Figure 7. If threaded fittings are used, be sure to use pipe joint compound or thread sealing tape on outside threads.

Step B – 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:
· Install the Drain Adaptor included with your unit As shown in Figures 8-10, the drain adaptor is installed onto your sink’s drain pipe above the P-trap. This is normally used for under sink installations.
· Use another existing drain in your home As shown in Figures 11 and 12, 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. 8 & 10. 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. 9). Make sure that the Q.C. fitting is toward the direction of the RO faucet (See Fig. 10). 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. 9), 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 9, 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. 12. This type of drain is the preferred over the p-trap drain adaptor.
Be sure to provide a 1-1/2″ air gap between the end of the hose and the drain point. This will keep 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 tube and determine whether it is long enough to reach from the Reverse Osmosis filter assembly to the drain point . See Fig. 11.

2. If longer tubing is required, see parts list in back of manual and replace the red tube with an adequate length 1/4″ tubing.
3. Cut one end of the drain tube square. See Fig. 17.
4. Insert this tube all the way into the red collet fitting on the Reverse Osmosis filter assembly. See Figs. 18, 19 & 22.
5. Pull on the tubing to be sure it is held firmly in the fitting.
NOTE: A flow control insert is located inside the elbow fitting that the drain tube connects to. Refer to Fig 27. Leave this fitting in place.
6. Route the tubing to the drain point and secure at the end with a bracket (not included). See Fig. 12. Provide a 1-1/2″ air gap between the end of the tube and the drain. See Fig. 12.

Step D – 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 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, CorianTM or other plastic resin products or sinks made of porcelain or stainless steel may cause permanent, irreparable damage to the sink or countertop surface.

Step D – Install RO Faucet (cont.)

INSTALL REVERSE OSMOSIS FAUCET
1. Locate and organize your RO faucet install parts. Refer to Fig. 15.
2. Mount faucet base to sink hole until the faucet base is flat against the sink surface. The rubber gasket should be between the sink surface and the faucet base.
3. Tighten the toggle bolts (use a screwdriver to tighten from above) until the base is firmly mounted to the sink surface. Do not overtighten.
4. Locate the 1/4″ red tube and cut one end square. See Fig. 17.
5. Insert this tube all the way into the red collet fitting on the Reverse Osmosis filter assembly. See Figs. 18, 19 & 22.
6. Pull on the tubing to be sure it is held firmly in the fitting. 7. Locate the faucet body. The black and blue tubes are
already connected to the faucet. Insert these tubes into the sink hole until approximately one foot of tube length and the faucet body are left above the counter surface. Do not kink the tubes in the process. See Fig. 14.
NOTE: If you are going to route the red drain tubing directly to a remote drain point (see page 14), skip steps 8-11, and proceed to step 12.
8. Route the loose end of the 1/4″ red tube up through the countertop to faucet. See Fig. 22.
9. Cut tube square and to length. See Fig. 17. 10. Insert all the way onto the 1/4″ faucet barb fitting on
faucet. See Fig. 16. 11. Pull on the tubing to be sure it is held firmly in the fitting. 12. Mount the faucet body onto the faucet base, 1/4 turn.
FAUCET ELECTRONICS
Inside the faucet base is a battery operated 6 month timer. An amber LED indicator is also located in the front of the faucet base. This LED will flash continuously after 6 months has passed. This indicates that it is time to replace the battery, prefilter, and postfilter.
INSTALLBATTERY
To install battery, complete the following steps. 1. Remove the screw on the right side of the faucet base. 2. Press the battery housing upward from the front faucet
base until it releases from the faucet base. See Fig. 15. 3. Install the battery (CR 2032 or equivalent). Place battery

Step E – 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. 17.
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. 17. NOTE: Tubing lengths should allow for the removal of the assembly from the hanger washers for servicing. If tubing lengths are shortened for neater appearance, it may be necessary to keep the assembly on the hanger washers for service.
Connect tubes
1. Push tubing through collet, until it engages the o-ring. See Fig. 18. Continue pushing until the tube bottoms out against the back of the fitting. See Fig. 19. 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.
2. If additional tubing is required, see parts list at the end of this manual.
To Disconnect Tubes
1. Push the collet inward with a finger tip. See Fig.21.
2. Continue holding collet inward while pulling the tubing out. See Fig. 21.

Step F – 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. 23.
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 tube. Handle bleach according to bleach manufacturer’s recommendations. See Fig. 23.
5. Connect yellow tube to tank connector. See Figs. 13 and 22.
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 F – 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.

If you live in the state of Massachusetts, review plumbing code 248-CMR of the Commonwealth of Massachusetts before proceeding with the installation.

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) Water Filtration 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 Water Filtration System works.
Prefilter: Water from the cold supply pipe enters the prefilter. See Fig. 25. 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. 25. 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. 25. 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. 25. 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. 25. 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. 25.
Check Valve: A check valve is located in the Reverse Osmosis manifold above the center cartridge. The check valve blocks a backward flow of product water from the storage tank to drain. A backward flow could damage the Reverse Osmosis Membrane. See Fig. 25.
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. 25.

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.
The prefilter and postfilter are replaceable sediment cartridges with activated carbon in their composition. See Fig. 26. You must periodically replace the prefilter and postfilter cartridge. This will protect the RO membrane from being destroyed by chlorine. It will also keep 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. 26. 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.

DRAIN FLOW CONTROL
The flow control is required for proper operation of the Reverse Osmosis system. See Fig. 27. The flow control, located inside the push-in elbow fitting on the drain port of the Reverse Osmosis filter assembly, 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. 27. 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. 28 & 29.
2. Clean collet port, lubricate with silicone-based lubricant, and insert the o-ring seal into the bottom of the port. See Figs. 28 & 29.
3. Push the collet inward until it locks in place. See Figs. 28 & 29.

CHANGE BATTERY
To change battery, complete the following steps. 1. Remove the screw on the right side of the faucet
base. See Fig. 30. 2. Press the battery housing upwards from the front
faucet base until it releases from the faucet base. See Fig. 30. 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. 30.

from the water supply.

cartridges. See page 23.

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. See page 23.

Cause: Contamination in product water storage tank. Correction: Use sanitizing procedures. Replace prefilter and postfilter cartridges. See page 19.

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. See page 23.

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. See page 24.

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. See page 24.

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. See pages 10 & 14.

Problem: Faucet LED indicator light does not function after battery change.

Cause: Battery dead.

Correction: Replace with new battery. See page 24.

Cause: Battery installed incorrectly.

Correction: Install battery correctly. See page 16 or 24.

Problem: Water leaks at push connect fittings.

Cause: Tubing not cut square.

Correction: Cut tubing square. See pages 17 & 18.

Cause: Tubing not pushed in all the way.

Correction: Push tubing in all the way. See pages 17 & 18.

Cause: Tubing nicked.

Correction: Remove tube from connection. Remove nicked portion by cutting tube to shorter length. Reinsert in connection. See pages 17 & 18. If removing the drain line, leave in place the elbow fitting that it connects to. See page 24.

Cause: Outer tubing surface finish not smooth.

Correction: Remove tube from connection. Remove problem area by cutting tube to shorter length. Reinsert in connection. See pages 17 & 18. If removing the drain line, leave in place the elbow fitting that it connects to. See page 24.
