WQC4RO Series Watts Quick Change Reverse Osmosis System Instruction Manual

WQC4RO Series Watts Quick Change Reverse Osmosis System

Product Information: Watts Quick-Change (QC) Reverse Osmosis System

The Watts Quick-Change (QC) Reverse Osmosis System is a water filtration system that uses a semi-permeable membrane to remove contaminants such as TDS, sodium, and heavy metals like arsenic, copper, and lead.

The system has four stages of filtration:
sediment filter, carbon filter, membrane, and granular activated carbon (GAC) filter. The sediment filter traps sediment and other particulate matter like dirt, silt, and rust. The carbon filter reduces chlorine and other materials that cause bad taste and odor. The RO membrane is the heart of the system and removes TDS, sodium, and heavy metals. Finally, the GAC filter is used as a final polishing filter after the water storage tank. The system is tested and certified by WQA against NSF/ANSI Standard 58 for the reduction of the claims specified on the performance data sheet and NSF/ANSI Standard 372 for lead- free.

Product Usage Instructions

Before proceeding with installation, read the Installation Instructions and Maintenance Manual carefully. Failure to follow any attached instructions or operating parameters may lead to the product’s failure. If you are unsure about installing your WATTS water filter, contact a WATTS representative or consult a professional plumber.

Do not use the system with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. Test the water periodically to verify that the system is performing satisfactorily. Discard small parts remaining after installation. To ensure proper installation, handle all components of the system with care. Do not drop, drag or turn components upside down. Be sure the floor under the water filter system is clean, level, and strong enough to support the unit. Failure to install the system correctly voids the warranty.

It is recommended to change the sediment filter and carbon filter every six months, the GAC filter every 12 months, and the RO membrane every 2-5 years. When replacing the filter elements, pay special attention to any cleaning instructions mentioned in the system manual. Just because you cannot taste it, does not mean that it is not there. Contaminants such as lead, chromium, and arsenic (to name a few) are undetectable to the taste. Over time, if you do not replace the filter element, other bad tastes and odors will be apparent in your drinking water. Keep the Installation Instructions and Maintenance Manual for future reference.

Introduction

Thank you for your purchase of a state of the art Watts Reverse Osmosis (RO) water treatment system. Water quality concerns are becoming more of a focus for the public. You may have heard about contaminants in the drinking water, such as Arsenic, Chromium. There may also be some local water issues such as high levels of Lead and Copper. This Watts water treatment system has been de- signed and tested to provide you with high quality drinking water for years to come. The following is a brief overview of the system.

Your Reverse Osmosis System:
Osmosis is the process of water passing through a semi-permeable membrane in order to balance the concentration of contaminants on each side of the membrane. A semi-permeable membrane is a barrier that will pass some particles like clean drinking water, but not other particles like arsenic and lead. Reverse osmosis uses a semi-permeable membrane; however, by applying pressure across the membrane, it concentrates contami-nants (like a strainer) on one side of the membrane, producing crystal clear water on the other. This is why RO systems produce both clean drinking water and waste water that is flushed from the system. This reverse osmosis system also utilizes carbon block filtra-tion technology and can, therefore, provide a higher quality drinking water than carbon filtration systems alone. Your system is a 4-Stage RO which is based upon separate treat-ment segments within the one complete water filtration system.

These stages are as follows:

• Stage 1 –

  • Sediment filter
    Recommended change 6 months. The first stage of your RO system is a five- micron sediment filter that traps sediment and other par-ticulate matter like dirt, silt and rust which affect the taste and appearance of your water.

• Stage 2 –

  • Carbon filter
    Recommended change 6 months. The second stage contains a five-micron carbon block filter. This helps ensure that chlorine and other materials that cause bad taste and odor are greatly reduced.

• Stage 3 –

  • Membrane
    Recommended change 2-5 years. Stage 3 is the heart of the reverse osmosis system, the RO membrane. This semi-permeable membrane will effectively take out TDS, sodium and heavy metals such as arsenic, copper, and lead. Because the process of making this high quality drinking water takes time, your RO water treatment system is equipped with a storage tank.

• Stage 4 –

  • GAC Filter
    Recommend change 12 months. The final stage is a granular activated carbon (GAC) filter. This filter is used after the water stor-age tank, and is used as a final polishing filter.

NOTICE
Filter & Membrane life may vary based upon local water condi-tions and/or use patterns.

System Maintenance

Just because you can not taste it, does not mean that it is not there. Contaminants such as lead, chromium and arsenic (to name a few) are undetectable to the taste. Additionally, over time if you do not replace the filter element, other bad tastes and odors will be appar-ent in your drinking water. This is why it is important to change out your filter at the recom- mended intervals as indicated in this system manual. When replacing the filter elements, pay special attention to any cleaning instructions. Should you have any further questions please contact the dealer that you purchased the unit from. With proper installation and maintenance, this system will provide you with high quality water for years to come. All of Watts water enhancement products are rigorously tested.

NOTE: This manual is used for several variations of the same system. Your system may vary slightly from the pictures or descriptions contained in this manual. It is the end users responsibility to ensure that this system is installed according to all local codes and regulations.

Installation

Operating Parameters

(6.0 kg/cm2)

| Minimum 40psi (2.80 kg/cm2)
pH Parameters| Maximum 11| Minimum 2
Iron| Maximum 0.2 ppm|
TDS (Total Dissolved Solids)| < 1800 ppm|
Turbidity| < 5NTU|

Hardness: Recommended hardness not to exceed 10 grains per gallon, or 170ppm. System will operate with hardness over 10 grains but the membrane life may be shortened. Addition of a water soft-ener may lengthen the membrane life.
Water Pressure: The operating water pressure in your home should be tested over a 24-hour period to attain the maximum pressure. If the incoming water pressure is above 85psi, a pressure regula-tor is recommended and if over 100psi, then a pressure regulator is required.
Copper Tubing: Reverse Osmosis water should not be run through copper tubing as the purity of the water will leach copper causing an objectional taste in water and pin holes may form in the tubing. Watts supplies speciality fi lters that can be used if copper tubing follows the Reverse Osmosis unit. Be sure to follow any state or local regulations during installation.

Using Quick-Connect Fittings

Cutting

Cut the tube square. It is essential that the outside diameter be free of score marks and that burrs and sharp edges be removed before inserting into fi tting.

Connecting

Make certain to push the tubing completely into the connector until it comes into contact with the internal tubing stop. The collet (gripper) has stainless steel teeth which hold the tube fi rmly in position while the O-ring provides a permanent leak proof seal. Pull on the tube to check that it  is secure. It is a good practice to test the system prior to leaving the site and/or before use.

Disconnecting

To disconnect, ensure the system is depressurized before removing the tube. Push in collet squarely against the face of the fi tting. With the collet held in this position, the tube can be removed. The fi tting can then be reused.

• Step B – Open cold water sink faucet to relieve pressure.
• Step C – Choosing the configuration that fits your plumbing, attach the Adapt-A-Valve as illustrated in the diagram above.

NOTICE
Make sure that the black collet is installed in to the 1/4″ opening on the Adapt-a-valve. Don’t forget to install the white compres-sion washer with the 3/8″ configuration. Brass adapters do not need to be tightened with a wrench, only finger tight.

STEP 4
Drain Saddle Installation

NOTICE
If you have a garbage disposal, do not install the drain saddle near it. Installation of the drain saddle must be either above the garbage disposal, or if a second sink drain is available, install it above the cross bar on the second drain. Installation of the drain saddle near a garbage disposal may cause the drain line to plug.

• Step A – Determine if a 1/4″ tube connection or 3/8″ tube connection drain saddle should be installed. For Air-Gap RO Faucets (3 tubes) use larger 3/8″ tube connection drain saddle. For non air-gap RO faucets (1 tube) use 1/4″ tube connection drain saddle.

• Step B – Gather the pieces of the drain saddle:

  • (1) Saddle – Front Portion
  • (1) Saddle – Rear Portion
  • (1) Foam Gasket
  • (2) Screws
  • (2) Nuts (for Screws)
    NOTICE
    The drain saddle must be installed at least 1½” above the nut of the P-Trap elbow or cross bar from the garbage disposal to ensure proper drainage.

• Step B – Using a 3/8″ drill bit for 3/8″ drain saddle or 1/4″ drill bit for 1/4″ drain saddle, drill into the drain pipe at best available loca-tion as specified above, for drain saddle installation. Take extreme caution to only drill through one side of the drain pipe.

• Step C – The small square black foam gasket with a circle cut out of the middle must be applied to the inside of the drain saddle. Remove sticky tape backing and stick to the drain saddle as shown.

• Step D – Assemble the drain saddle around the drain pipe and align drain saddle fitting opening with the hole drilled in the previous step – you may use a small screwdriver to feed through the drain saddle into the drain pipe to aid with the alignment. Us-
  ing a Phillips screw driver tighten the drain saddle bolts evenly and securely on both sides. NOTICE
  Do not over tighten the screws. It may crack the drain saddle. NOTICE
  The Flow Restrictor is installed inside of the red tube at the bent end connected to the Drain port on the back of the RO module. DO NOT REMOVE THE FLOW RESTRICTOR OR CUT THE RED TUB-ING AS IT WILL DAMAGE THE FLOW
  RESTRICTOR.

STEP 5 – Option 1
1/4″ Drain Saddle Option (For Use with Non-Air Gap Faucets)

• Step 1.A – In the parts bag, locate the 1/4″ red tube. Connect the tube to the union fitting attached to the 1/4″ red tube that is connected to the back of the RO Module fitting labeled Drain. Make sure the tube is pushed in all the way to the tube stop.
• Step 1.B – Push the 1/4″ red drain tube open end through the black compression nut included in the drain saddle kit. Insert the drain tube into the opening in the drain saddle, hand tighten the black nut and add 1/4″ turn with a wrench. Continue to Step 6.

STEP 5 – Option 2
3/8″ Drain Saddle Option (For Use with Air Gap Faucets)

• Step 2.A – Locate the 1/4″ red tube attached to the RO Faucet. Connect the tube to the union fitting attached to the 1/4″ red tube that is connected to the back of the RO Module fitting labeled Drain. Make sure the tube is pushed in all the way to the tube stop.
• Step 2.B – Measure the 3/8″ black tube from faucet to the drain saddle on the drain pipe and make a straight cut to the correct length.
• Step 2.C – Connect the black tube to the open quick connect fi tting on the drain saddle by pushing the tube all the way to the tube stop. Continue to Step 6. NOTICE
  The black 3/8″ drain tube must be as SHORT and STRAIGHT as possible to the drain saddle, making a downward slope from faucet to drain saddle to allow for proper drainage. This is a gravity fed line and if there is any bend or dip in the tube, the rinse water will not fl ow into the drain properly. Water may back up and come out the air gap hole in the back of the faucet.

STEP 6
Blue 1/4 ” Tube Connection – Faucet

Connection

• Step A – Locate the 1/4 ” blue tube connected to the RO Faucet. Connect the open end to the 1/4 ” elbow fi tting on the back of the RO Module behind the Post-Carbon Filter. Make sure the tube is pushed in all the way to the tube stop.

STEP 7
Black 1/4 ” Tube Connection – Inlet Water

• Step A – Locate the 1/4 ” black tube from the parts bag and insert one end into the plastic Adapt-A-Valve. Make sure the tube is pushed in all the way to the tube stop.
• Step B – Insert the other end of the 1/4 ” black tube into the elbow behind the sediment fi lter next to the “IN” label.

STEP 8
Tank Valve Installation

• Step 1.A – PTFE thread seal tape must be applied in a clockwise direc-tion. Wrap 5 to 7 turns around the male pipe threads (MPT) on the stainless steel fi tting on top of the tank.
• Step 1.B – Thread the plastic valve onto the tank fi tting
  NOTICE
  DO NOT over-tighten or the valve could crack

STEP 9
White 1/4 ” Tube Connection – Storage Tank

• Step A- Locate the 1/4 ” white tube from the parts bag. Plug one end into the RO Module at the open port of the ASO Valve marked “Tank”
• Step B – Plug the other end of the 1/4 ” white tube into the valve at the Storage Tank.

STEP 10
Reverse Osmosis Module Mounting

• Step A – Determine the best location for the RO Module to be mounted to allow for future system maintenance. The parts bag has 2 self-tapping screws. Using an electric drill with a phillips-driver bit, screw them into the cabinet wall approximately 10 5/8″ apart and 16″ from the bottom of the cabinet.

STEP 11
Install the Filter Cartridges

• Step A – Identify each cartridge and the proper location on the system by matching the colors and descriptions.
• Step B – Insert each cartridge with a 1/4 -turn in a counter-clockwise direction. The cartridge is installed properly when the label is facing toward the front of the unit.

Operation

Startup Instructions

• Step A – Turn on the water supply at both the cold water supply valve and Adapt-A-Valve. Check the system for leaks and tighten any fittings as necessary. (Check frequently over the next 24 hours to ensure no leaks are present).
  NOTE: If you have connected your RO system to a refrigerator / ice maker, make sure the ice maker is off (do not al-low water to flow to the ice maker) until flushing (Step D) is complete and the tank has been allowed to fill completely. Connection from the RO to the ice maker system should have an in- line valve installed before the ice maker so it can easily be closed to prevent water flowing to the ice maker during start up and peri-odic maintenance. Your storage tank must be allowed to fill up fully in order for the ice maker system to work properly.

• Step B – Open the RO faucet and leave it open until water begins to trickle out (this may take a few minutes and the water will come out slowly).

• Step C – Close the RO faucet allowing the storage tank to fill with water. It may take 3 to 6 hours to fill the tank completely depending on the production capability of the membrane, local water temperature and water pressure.
  NOTE: During the fill period you may hear water trickling
  which is a normal occurrence.

• Step D – After the storage tank has filled open the RO Faucet to flush the tank completely. You will know that the tank is empty when the flow rate from the RO faucet is down to a trickle. Repeat this step two more times. The fourth tank can be used for drinking.
  NOTE: The flushing process should take about a day to complete.
  NOTE: Flushing of the tank 3 times is only necessary during the initial startup and after replacing the membrane.

Maintenance

NOTICE
Your RO module is equipped with valved heads which will auto-matically turn off the water supply to each filter when the filter is released, thus you do not need to turn off the incoming water supply at the Adapt-a-Valve. The RO faucet must be off when filters are replaced.

Month System Maintenance

Determine if you have an 11 inch or 13 inch product and replace in 6 mos.

Annual Maintenance

Determine if you have an 11 inch or 13 inch product and replace in 12 mos.

• Tip : This is a good time to check the air pressure in your storage tank. For instructions please see page 9.

• Step A – Place a towel under the RO module to catch any excess water that may drip out from the filters during the changeover.

• Step B – To remove a filter cartridge : Turn the cartridge 1/4-turn to remove.
  Step C – To install a filter cartridge:
  Remove the seal cap and insert the cartridge into the valve head with the label facing to the left (9 o’clock position) and then rotate it 1/4-turn.

• Step D – If performing the annual maintenance, flush the first tank full after completing the annual maintenance.
  This reverse osmosis system contains a replaceable component (the RO membrane) which is critical to the efficiency of the sys-tem. Replacement of this reverse osmosis membrane should be with one of identical specifications as defined by Watts to assure the same efficiency and contaminant reduction performance.

RO Membrane Replacement

Determine if you have an 11 inch or 13 inch product and replace in 2-5 years.

Membranes have a life expectancy between 2 and 5 years, de-pending on the incoming water conditions and the amount the RO system is used. This reverse osmosis membrane is critical for effective reduction of total dissolved solids (TDS). The prod-uct water should be tested periodically to verify that the system is performing satisfactorily. Normally, a membrane would be replaced during a semian-nual or annual filter change. However, if at any time you notice a reduction in water production or an unpleasant taste in the reverse osmosis water, it could be time to replace the mem-brane. Watts recommends replacing the membrane when TDS reduction falls below 75%. Refer to Instructions above filter change instructions

• Step A – To change your membrane, follow the instructions for the Annual Maintenance (previous section). The procedure to remove and change the membrane cartridge is the same as all the other filter cartridges on the RO module.
• Step B – Check over the next 24 hours to ensure no leaks are present.

Annual Sanitization

NOTICE
Do not change your post-carbon filter until the sanitization has been complet- ed. The pre-filters and membrane can be changed before the sanitization

• Step A – Turn off the water supply to your RO system at the Adapt-A-Valve and open the RO faucet to drain the storage tank.
  NOTICE
  If you have connected your RO system to a refrigerator/ice maker, make sure the connection has been turned off. Do not re-open the connection until the sanitization process is complete.

• Step B – Locate the tube that runs between your filter module and the storage tank and disconnect at both ends.

• Step C – Drain any remaining water in the tube

• Step D – Hold both ends of the tube together with the ends pointed away from your face. Using a dosing syringe (see figure) slowly insert 1 teaspoon (5 mL) of common household bleach into the tube. WARNING
  Do not use needle syringe

• Step E – While covering one end of the tube with your finger, insert the other into the tank. Then insert the open end into the filter module.

• Step F – Turn the incoming water back on and let the system fill for approximately 10 minutes

• Step G – Turn off the incoming water and let the system sit for 1 minute.

• Step H – Drain the system completely and then follow the startup procedure – filling then draining two full tanks of water.

• Step I – Replace the post-carbon filter once complete.

DANGER
IF BLEACH GETS IN EYES: Hold eye open and rinse slowly and gently with water for 15 – 20 minutes. Remove contact lenses if present, after the first 5 minutes, then continue rinsing eye. Call a poison control center or doctor for treatment advice.

Check Air Pressure in the Tank

NOTICE
Check air pressure only when tank is empty of water! Check air pressure in the storage tank when you notice a decrease in available water from the RO system. Air can be added with a bicycle pump using the schrader valve that is located on the lower side of the tank behind the blue plastic cap.

• Step A – Turn off the incoming water sup- ply to the RO.

• Step B – Open the RO Faucet and water to drain from the tank until it is completely empty.
  TIP : When water from the RO faucet slows to a trickle, with the faucet still in the open position, you may add air to the tank to purge any left over water, this will ensure that the tank is completely empty.

• Step C – Once all water in the tank is purged, check air pressure using an air pressure gauge, it should read between 5 – 7 PSI. (Digital air pressure gauge is recommended)

• Step D – Follow startup procedure on page 8.

Procedure for Extended Non-Use (More than 2 months)

• Step A – Turn off the water supply to your RO system at the Adapt A-Valve and open the RO faucet to drain the storage tank. Once the storage tank is empty, remove all filter cartridges (order not important), place them into a sealed plastic bag and store in your refrigerator.
  NOTICE
  DO NOT FREEZE

Restart Instructions

• Step A – Reinstall all filters on to the RO unit. Filters are color coded to match the filter heads they snap in to. Refer to page 7, Step 11 for cartridge installation procedure.

• Step B – Turn on water supply to the system at the Adapt-a-Valve. Check frequently over the next 24 hours to ensure no leaks are present.
  NOTICE
  If you have connected your RO system to a refrigerator / ice maker, make sure the ice maker is off (do not allow water to flow to the ice maker) until the tank has been allowed to completely fill.

• Step C – Open the RO faucet and leave it open until water begins to trickle out (it will come out slowly).

• Step D – Close the RO faucet allowing the storage tank to fill with water. It may take 3 to 6 hours to fill the tank completely depending on the production capability of the membrane, local water temperature and water pressure.

• Step E – After the Tank has filled, open the RO Faucet to flush the tank completely. You will know that the tank is empty when the flow rate from the RO faucet is down to a trickle. The second tank can be used for drinking.

This system has been tested according to NSF/ANSI 58 for reduction of the substances listed below, and to NSF /ANSI 372 for lead free com-pliance. The concentration of the indicated substances in water entering the system was reduced to a concentration less than or equal to the permissible limit for water leaving the system as specified in NSF/ANSI 58. 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 ar-senic, but may not remove other forms of arsenic. This system is to 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 of the Performance Data Sheet for further information.

Arsenic Fact Sheet

Arsenic (As) is a naturally occurring contaminant found in many ground waters. Arsenic in water has no color, taste or odor. It must be measured by an arsenic test kit or lab test. Public water utilities must have their water tested for arsenic. You can obtain the results from your water utility contained within your consumer confidence report. If you have your own well, you will need to have the water evaluated. The local health department or the state environmental health agency can provide a list of test kits or certified labs.

There are two forms of arsenic:
pentavalent arsenic (also called As (V), As (+5)) and trivalent arsenic (also called As (III), As (+3)). In well water, arsenic may be pentavalent, trivalent, or a combination of both. Although both forms of arsenic are potentially hazardous to your health, trivalent arsenic is considered more harmful than pen-tavalent arsenic. RO systems are very effective at removing pentavalent arsenic. A free chlorine residual will rapidly convert trivalent arsenic to pentavalent arsenic. Other water treatment chemicals such as ozone and potas-sium permanganate will also change trivalent arsenic to pentavalent arsenic. A combined chlorine residual (also called chloramine) where it does convert trivalent arsenic to pentavalent arsenic, may not con-vert all the trivalent arsenic in to pentavalent 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. This reverse osmosis system is designed to remove up to 98% of pentavalent arsenic. It will not convert trivalent arsenic to pentavalent arsenic. Under laboratory standard testing conditions, this system reduced 0.30 mg/L (ppm) pentavalent arsenic to under 0.010 mg/L (ppm) (the USEPA standard for drinking water). Actual performance of the system may vary depending on specific water quality condi-tions at the consumer’s installation. In addition to the independent laboratory standard testing conditions we have conducted additional field testing on our reverse osmosis units to determine trivalent arsenic reduction capabilities. Based upon field testing, it has been determined that the RO units are capable of reducing up to 67% of trivalent arsenic from the drinking water. This reverse osmosis system contains a replaceable component critical to the efficiency of the system. Replacement of the reverse osmosis component should be with one of identical specifications, as defined by the manufacturer, to ensure the same efficiency and contaminant reduction performance. Specific component identifi- cation and ordering information can be found in the maintenance section of this manual.
