† This appliance 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 appliance reduces pentavalent arsenic, but may not remove  other forms of arsenic. This appliance is to be used on water supplies containing detectable free chlorine residual at the appliance 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.
Arsenic Facts
Arsenic (abbreviated As) is found naturally in some well water. Arsenic in water has no color, taste, or odor. It must be measured by a laboratory 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. Information about arsenic in water can be found on the Internet at the U. S. Environmental Protection Agency website: www.epa.gov/safewater/arsenic.html. 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 arsenate). In well water,  arsenic may be pentavalent, trivalent, or a combination of both. Special sampling procedures are needed for a lab to determine what type and how much of each type of arsenic is in the water. Check with the labs in your area to see if they can provide this type of service.
Reverse osmosis (RO) water treatment systems do not remove trivalent arsenic from water very well. 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 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. The QCRO4V-50 system is designed to remove pentavalent arsenic. It will  not convert trivalent arsenic to pentavalent arsenic. The system was tested in a lab. Under testing conditions, the system reduced [0.30 mg/L (ppm) or 0.050 mg/L (ppm)] pentavalent arsenic to 0.010 mg/L (ppm) (the USEPA standard  for drinking water) or less. The performance of the system may be different at your installation. Have the treated water tested for arsenic to check whether the system is working properly.
The RO component of the QCRO4V-50 system must be replaced every three (3) years to ensure that the system will continue to remove pentavalent arsenic. The component identification and locations where you can purchase the component listed in this installation/operation manual.
Suggested Installation Equipment

Overview of the Quick Change RO System’s Components

1. Manifold Assembly
   The manifold assembly serves as the functional hub of the system by directing the flow through each of the system’s main components.

2. Sediment Filter
   The sediment filter screens out particulate material, such as dirt, sand, or rust, which may clog the other filters in the system.

3. Activated Carbon Prefilter
   The activated carbon prefilter reduces chlorine which may damage the RO membrane filter. It must be regularly checked and/or replaced to prevent premature membrane failure and poor water quality.

4. Reverse Osmosis Membrane
   The RO membrane (4) reduces dissolved substances and other microscopic impurities. It consists of a membrane envelope wound around a perforated tube. Product water diffuses through the  membrane to the inside of the envelope where it flows to and is collected by the tube. Impurities are flushed away in the drain stream.
   The RO membrane featured in the system offers exceptional contaminant rejection, application versatility, and long life. The membrane material is sensitive to an attack by chlorine. The activated carbon filter must be maintained  properly to prevent premature failure of the RO membrane.
   For long term storage the RO membrane should be refrigerated to maximize performance once used. DO NOT ALLOW TO FREEZE. NOTE: This preservative must be flushed from membrane before use. If ingested it may cause irritation of the gastrointestinal tract, colic, diarrhea, or other similar symptoms. The manufacturer recommends discarding all the  product water for at least one hour of operation before drinking or use in food preparations. Water Group highly recommends discarding the product water for a full 24 hours to flush the preservative and to properly hydrate the  membrane for maximum performance.

5. Polishing Filter
   The polishing filter (5) adsorbs any residual tastes and odors just before the water is delivered through the faucet.

6. Drain Line Flow Control
   The flow control assembly or concentrate flow control (6) regulates the flow rate of the flushing (drain) stream and to maintain pressure in the RO membrane filter.

7. Automatic Shutoff
   The automatic shutoff (7) automatically stops the flow of water through the system when the storage tank is full.

8. Dispenser Faucet
   The faucet (8) allows the product water to be drawn from the system with a simple rotation of the handle. This air gap style faucet prevents the unit from siphoning drain water back into the system. It features a built-in siphon break for concentrate discharge as required by most plumbing codes.

9. Storage Tank
   The storage tank (9) collects and stores the water produced by the RO system. A compressed air diaphragm drives the water to the polishing filter and faucet. The ball valve (11) provides a convenient way to lock water in the tank  during transport and filter changes.
   NOTE: Cleanliness is essential in the Preparation procedure. Be sure to wash your hands thoroughly before handling filters. The use of surgical gloves is strongly recommended.

Product Information

This manual covers the technical aspects of Quick Change drinking water systems. It is important to read this manual thoroughly so that you can properly apply, install, and service these systems.
The substances reduced by this system are not necessarily in the customer’s untreated water.
Warranty
A limited warranty is extended to the original end user from Water Group. This warranty is printed on the back cover of the Owner’s Guide.
Application Guidelines
The system is designed for use on potable water supplies meeting the guidelines outlined in Table 1. The system should be installed on a home’s cold water line. The flushing stream should discharge through an approved siphon break.  Installation of this system must comply with state and local laws and regulations.
Package Content
The system is shipped from the factory in carton:
NOTE: The filter elements are shipped in their own sealed packaging. This will help to simplify preparation of the system and to maximize the shelf life of the RO membrane element.

Preparation

Tubing Connectors
The system features reliable and convenient push-to-connect tubing connectors. Tubing is easily connected and disconnected from these fittings as follows.

Connect:
Cut the tubing squarely with a sharp knife. Be careful not to crush the tubing. To avoid leaks, make sure the tubing end is smooth and free of burrs and abrasions. Lubricate the end of the tube with water or a light coat of silicone and push the tube end firmly into the fitting. You should feel it push past the O-ring. Avoid bending the tubing sharply away from the fitting.

Disconnect:
Hold the collar against the fitting body and pull the tube from the fitting.
In the unlikely event that the connection leaks, remove and recut the tubing.
Check the inside of the fitting for debris or O-ring damage. Reconnect.
Push-to-connect tubing connectors grip the outside diameter of the tube. To help assure a reliable connection, it is important to use high quality tubing with a consistent outside diameter.
Verify Flow Control Location
The RO manifold comes attached with the elbow fitting flow control. This flow control is attached to the manifold by quick disconnect fitting which allows it to be easily changed. Verify it is properly located in the outlet next to the symbol.

Storage Tank Preparation
NOTE: Changing the air pressure will alter the amount of water stored in the tank. Increasing the pressure will decrease capacity while decreasing pressure will increase capacity.

Installation

The exact placement of the components will vary by installation. Although shown beneath a sink, it may be installed in a basement, crawl space, or in an adjacent cabinet. Regardless of where the system is installed, the flow sequence described by (figure 7) must be observed.
The drinking water system is designed to be mounted near a sink for easy access to cold water and drain lines. Lengths of 1/4-inch and 3/8-inch OD plastic tubing will be required to make this installation.
Evaluate the installation site to determine the easiest path for the plumbing to follow. Take care to make the installation as neat as possible.

NOTE: Install the 3/8” red drain line from the air gap faucet to the drain adapter so that it runs downward with no loops or low spots. Otherwise the unit will overflow at the air gap siphon break built into the faucet, or make irritating gurgling sounds.
For standard faucet (non-air gap) installations simply route the drain line directly to the drain connection.
The following steps will enable you to install the system quickly and orderly. Some variation may be necessary depending on the installation. See page 4 for a check list of tools and materials.
Typical installations follow this sequence:

1. Select Component Installation Locations
2. Faucet Installation
3. Install Adapter Valve on Water Supply
4. Connect System Drain
5. Install Reservoir Tank
6. Install Filter System Assembly
7. Start-Up

Step 1 – Select Component Installation Locations

• Dispenser Faucet – The faucet is designed to be mounted on the rear lip of the sink. It may be installed in an existing sprayer attachment hole or in a hole drilled at the time of installation. It may also be mounted to an adjacent counter top. It should be positioned so that water is dispensed over the sink. A 7/8” diameter hole is required.

• Important considerations:

• Access to the bottom (undersink) of the faucet is required for attachment of product water line.

• There should be no undersink obstructions which would prevent smooth tubing runs to the drain connection, or RO module assembly.

• Filter System Assembly – The filter system assembly is designed to be mounted on any rigid vertical surface such as a cabinet sidewall, sheetrock in exposed stud. It should be positioned such that there is access to an inlet water source and drain. The installation should also allow convenient access for servicing.

• Inlet Water Supply Connection – Once a location is chosen for installation of the filter system assembly, select a nearby cold water line to provide the water source for the system.
  NOTE: Follow all local plumbing codes when connecting to service water.

• The Reservoir Tank – Position the reservoir tank near the faucet for optimum convenience. The reservoir tank will weigh about 28 pounds (13 kg) when full of water, so it must be positioned on a stand.
  The reservoir operates best in the vertical position, but it will operate on its side.

• Drain Connection – The most convenient entry to the drain is directly above the P-trap of the kitchen sink. However, the drain water from the system can be connected to adjacent sinks or a floor drain. Extra care should be taken when entering drains near dishwashers or food waste disposals as back flow may occur through the air gap and cause flooding.
  NOTE: Follow all local plumbing codes when connecting to drain.

Step 2 – Faucet Installation
To simplify its access and installation, we suggest you install the faucet on the rear lip of the sink. It should be evenly positioned with the sink faucet and spray attachment. Should the spray faucet hole not be available for the installation,
the sink must be drilled.
NOTE: It is recommended retaining the services of a professional counter top craft person when a hole is needed in granite or other specialty counter top materials.
Sink Drilling Instructions
Stainless Steel Sink

1. Select and mark the proper faucet location.
2. Center punch hole to provide a starting point for your drill.
3. Drill a 7/8” hole in the sink using a stepped 7/8” drill bit. If no stepped bit is available, start by drilling a 1/4” hole. Using this hole as a starting point progressively drill larger holes. Increase drill size by 1/8” until you reach a 7/8” hole.

Porcelain Enamel Sink
Follow these basic guidelines when drilling a porcelain sink:

One proven tool is the Repton porcelain cutter kit when used with a slow speed drill (300-400 rpm).

• Drill a pilot hole through the porcelain and base material with the carbide tip drill.
• Build a putty dam around the drill area. Add enough water to lubricate cutters and reduce cutting noise.
• Insert the porcelain cutter into the drill. Place the drill tip in the pilot hole. Check for free movement.
• Apply light pressure to the cutter tool and start the drill motor at low speed (300-400 rpm). When the initial cut has been made in the porcelain, speed may be increased. After a complete ring has been cut through the porcelain, change over to the metal cutter. Avoid contacting the outer rim of cut porcelain when drilling.

CAUTION! Avoid high drill speed during penetration of porcelain. A single speed drill can be used at a slow speed by switching it on and off quickly.

• Use a slow speed and light pressure to cut away the porcelain.
• Stop when you reach the metal under the porcelain. Remove the cutter and clean the porcelain chips from the
  surface. Continue cutting through the metal.

NOTE: Ceramic tile counters should be treated like porcelain when penetrating the surface, then treated as metal to complete the hole with carbide drills. Formica countertops can be drilled with a high-speed wood drill.
Air Gap Faucet (Standard) NOTE: The spacer is required for stainless steel sinks and thin counter tops. If sink is being installed on a thick (5/8” or thicker) counter the spacer is not required. Remove white protective film from faucet base.
Non Air Gap Faucet (Optional) Standard Faucet Installation

1. Remove white protective film from faucet base. Install faucet body, small rubber washer, metal base, and large rubber washer above sink (items 1-4).
2. Install plastic washer, lock washer and nut (items 5-7) onto faucet stem below sink and tighten. Be sure to properly align the faucet.
3. Install the faucet adapter (item 8). Connect the 3/8″ blue tubing to the faucet adapter.
   NOTE: If installing a standard faucet the red 1/4” drain line will be installed directly to the drain. Disregard the instructions on the following page.

Air Gap Faucet Installation

Remove white protective film from faucet base. Verify faucet body, metal base, and rubber base washer are in place above sink (Items 1, 3, and 2).
Lower faucet into mounting hole and place faucet over hole.
Install slotted washer, spacer, faucet washer, and nut onto faucet nipple below sink and snug them up (Items 4, 5, 6, 7 and 8). Be sure to properly align faucet before tightening. Do not over tighten.
Install faucet connector (Item 9), packaged with faucet, onto faucet nipple.
The spacer is typically necessary on stainless steel sinks and thin counter tops. If counter top or sink is too think (5/8” or thicker) remove the spacer from the installation.
CAUTION! Plastic Parts will break if screws are over tightened!

Tubing Connections

1. At the bottom of the faucet assembly you will find three tubing connections; 2 are barbed and one is a push in type fitting.

2. For the Air gap you will use the 2 barb fittings, the smaller fitting is for the 1/4” tubing and will be connected to the RO system. The larger barb fitting will use the 3/8” tubing and will be connected to the drain.
   NOTE: If you have difficulty fitting the tubing onto the barbed fittings, try running hot water over the end of the tubes.
   NOTE: Cut the tubing to be longer than what you will need because you will be able to trim it after you install the faucet assembly. Prepare the tubing with a fresh cut and make sure that it is free of dirt and any foreign materials.

3. Take another length of 3/8” tubing and make sure it is has a fresh cut and is free of foreign materials and any scratches on the outside surface. Install the tubing into the push in type fitting at the base of the faucet. Make certain that  it is inserted all the way in; once inserted give it a slight pull to make sure it is locked into the fitting. You have now completed the tubing connections. NOTE: To disconnect tubing from the product water fitting, hold the collet firmly against fitting body and pull the tube from the fitting. Repeated assembly and disassembly will cause wear to the inner body. Visually inspect for  excessive wear and replace the inner body as needed to protect against any leaks.

Cleaning the Faucet
Wipe the faucet with a soft cloth, avoid abrasive cleansers.
Step 3a – Install Adapter Valve on Water Supply (Part # ASVPP5LF)
CAUTION! The Adapter valve should be connected to cold water supply only. Connection to hot water supply will damage the system and will void all warranty

Before installing the adapter valve onto the supply line, install the adapter as needed. The conversion adapter can be threaded to either side of the valve to allow the valve to fit both 1/2” and 3/8” supply lines. 

Step 3b – Install T Adapter Valve on Water Supply (Part # 60010643)

Step 4 – Connect System Drain
Plumbing codes require that the drain from reverse osmosis drinking water systems be discharged through an air gap siphon break. The faucet incorporates an air gap into its body. The discharge from the air gap must be connected to the
plumbing system for proper drainage. This connection can usually be made beneath the sink. Incorrect installation may result in overflow of the air gap or excessive noise. If the concentrate water is discharged to an open drain, the air  gap may not be necessary.
For Air Gap installations select the 3/8” saddle, for Standard installations use the 1/4” saddle.
Connections to undersink plumbing can be made with a saddle clamp designed to accept the drain tubing from the faucet. Drain Saddle Kit is supplied for 1-1/2” undersink drain plumbing (Figure 14). Be sure to check and follow local plumbing codes prior to installation.
NOTE: For installation in Massachusetts, Plumbing Code 248 CMR shall be adhered to. Consult your licensed plumber for installation of this system. The use of saddle valves is not permitted in Massachusetts.

1. Install the drain saddle valve on to the drain pipe. See figure 7 on page 9 for its location. Use 3/8” saddle for air gap faucets or 1/4” saddle for standard faucets.
   WARNING! Do not overtighten.

2. Tighten the clamps with the help of the two bolts.

WARNING!   Do not drill through both sides of pipe!.

3. For standard faucets drill a 1/4” hole through one side of the pipe. For air gap faucets drill a 3/8” hole. The drill should be kept straight and centered to avoid damaging the saddle valve. Do not drill through both sides of the pipe!

4. Attach 3/8” or 1/4” red tube by slipping the tube through the black compression nut and hand tighten the nut on to the saddle valve.
   CAUTION: The drill should be kept straight and centered to avoid damaging the saddle valve.

Many homes are equipped with disposals and dishwashers. Special care must be taken when these appliances are present to prevent improper air gap performance. Home drain plumbing must be free of any blockage since this may cause  a backup of dishwasher and disposal waste into the air gap outlet tube and result in improper air gap performance. To perform a simple drain check, fill the sink basin with several inches of water, pull the plug, and observe the drainage. If water backs up into the second sink (if present), or if drainage is slow or there is excessive gurgling, drain blockage may be present.
Undersink drain plumbing usually resembles one of the following descriptions. In all cases, the drain tubing from the air gap (RO outlet) should run downward, free of dips and loops. The air gap outlet must not be connected to the  effluent side of the trap. This can vent sewer gas, which will produce foul odors.
Single basin sink without disposal

• Connect the RO outlet to the tailpiece directly beneath the sink.
• If a dishwasher drain connection is present, the RO outlet must be connected above it.

Single basin sink with disposal

• Connect the RO outlet to the dishwasher drain port on the disposal if available.
• If the dishwasher drain port is not available, other arrangements must be made such as running the RO outlet to a basement sump.
• Do not connect the RO outlet to the plumbing below the disposal.

Double basin sink with disposal, single trap

• The fitting which joins the drains from the disposal and second sink should be directional. If not, then we recommend that it be replaced.
• Connect the RO outlet to the tailpiece just below the second sink.
• If a dishwasher drain is present and cannot be relocated, the RO outlet must be connected above it.
• Do not connect the RO outlet to the horizontal plumbing between the two sink drains.

Double basin sink with disposal, double trap

• Connect the RO outlet to the tailpiece just below the second sink.
• If a dishwasher drain is present and cannot be relocated, the RO outlet must be connected above it.

Step 5 – Install Reservoir Tank
Place the reservoir tank in the location previously selected.
Step 6 – Install Filter System Assembly
The mounting bracket contains four mounting slots. The holes are sized to accept #10 round head wood screws (supplied).
Some types of surfaces such as particle board or drywall, may require the use of plastic screw anchors or toggle bolts to provide adequate support for the unit.

1. Tape the paper template included with this unit to the wall with the base of the template on the bottom of the cabinet (or higher). Be sure to leave adequate space (8 1/2” or more from the centerline) on both sides of the template.
2. Drill 1/8” hole at each location as indicated on the template.
3. Remove template. Thread one of the included wood screws into each hole leaving approximately a 1/2” space between the screw head and mounting surface.
4. Hang the bracket on the mounting screws. If unit is loose, tighten the screws further.

Install Filter Cartridges

1. Twist the cartridge to lock it into the manifold. (as shown)

Connect System
When cutting plastic tubing, use a sharp utility knife. Cut the tubing squarely. See page 7 for cutting and connecting tubing.

1. Connect quick connect elbows to the three open connection locations on the unit. Firmly push the fittings into place, then pull back lightly to lock them in.
2. Connect 1/4-inch OD white plastic tubing from the feed water supply source to the system inlet on the manifold.
3. Connect 3/8-inch OD blue plastic tubing from the product water faucet to the manifold.
4. Connect the 1/4” OD red tubing from the air gap inlet of the faucet to the concentrate outlet on the RO manifold.
5.  Connect the 3/8” OD white product water tube from the tank to the manifold.
6. Attach locking clips to each white elbow fitting. Do not attach one to the blue flow control. Clips should slide in behind collet on the fittings.

Step 7 – Start-Up

1. Sanitize the storage tank (see page 20 for sanitization procedure).
2. Check system to verify all components are correctly installed
3. Open inlet valve and tank valve.
4. Check system thoroughly for leaks. If any are found, shut off both inlet and tank valves and correct the issue.
5. Allow system to run & fill tank for 1-2 hours. You will hear the water running to drain while the unit is running. Once the water stops running to drain the tank is full.
6. Open faucet to flush carbon fines & sanitization solution. Once the flow begins to slow down (around 20 minutes after opening) turn off the faucet.
7. Allow the tank to fill completely again.
8. Once full, open the faucet and allow the water to run for 24 hours to break-in the RO membrane and completely flush the system. This will allow your system to run at optimal efficiency.
9. Close faucet and allow tank to fill.
10. System is ready to use

NOTE: It is normal if the air gap faucet makes gurgling noises and drips small amounts of water during start-up procedure. This should subside once start-up procedure is complete.
WARNING! Do not drink water produced by the system until the start-up procedure has been followed completely!

Performance & Technical Information

The performance of the system can be characterized and judged by the quality and quantity of the water produced by the system. By measuring the contaminant removal performance and flow rates of the system, its operating status can  be easily evaluated.
Factors Which Affect Performance
Performance of the reverse osmosis membrane is affected by several factors which must be considered when judging the condition of the system. The main factors which affect system performance are pressure, temperature, total dissolved solids level, recovery and ph.
Pressure
Water pressure affects both the quantity and quality of the water produced by the RO membrane. Generally, the more water pressure, the better the performance of the system. Be careful not to go below 40 psi or exceed 100 psi, the minimum and maximum operating pressure of the system.
Temperature
The reverse osmosis process slows with decreasing temperature. To compensate, a temperature correction factor is used to adjust the actual performance of the RO membrane filter to the standard temperature of 77°F (25°C). This allows
the performance of the unit to be accurately gauged against published standards. Temperature does not affect the concentrate flow rate.
Total Dissolved Solids
The minimum driving force which is necessary to stop or reverse the natural osmosis process is termed osmotic pressure. As the total dissolved solids level of the feed water increases, the amount of osmotic pressure increases and acts as  back pressure against the reverse osmosis process. Osmotic pressure becomes significant at TDS levels above 500 mg/L (ppm).
Hardness
Hardness is the most common membrane foulant. If ignored, this relatively harmless component of feed water will scale a membrane over time. Use of a softener will reduce the fouling effect on a membrane. One way to detect too much hardness in the feed water is the weight of a membrane installed for a period of time. A fouled membrane (dried) will weigh significantly more than a new membrane. The increase in weight is a result of precipitated hardness inside the membrane.
Iron
Iron is another common membrane foulant. There are a variety of types of iron, some of which cannot be removed by an iron filter. Clear water iron can be removed more effectively by a softener. Particulate iron can be removed more effectively by a 1 micron filter. Organic-bound iron can be removed only by activated carbon or microporous anion resin. If there is enough iron to exceed the EPA secondary drinking water standard and softening the water is not an option and the iron is soluble, then an iron filter is appropriate. If none of these are an option then regular replacement of membranes will have to be accepted.
NOTE: Increased weight of the RO cartridge may be a foulant other than hardness.
Product Water Recovery
Product water recovery plays an important role in determining membrane and system performance. Recovery refers to the amount of water produced in relation to the amount of water sent to drain. The standard calculation is:
% Recovery = Product Water ÷ (Product Water + Waste Water) x 100
The system uses a flow control assembly to restrict the flow of waste water to the drain. This restriction helps maintain pressure against the membrane. The sizing of the flow control assembly determines the recovery rating of the system.  The system is manufactured with a recovery rating designed to be around 25%. Depending on temperature, pressure and tolerances the actual recovery value may be slightly different for each system.
Performance Measurements
When collecting water samples from the manifold, insert a short 2”-3” length of tubing into the fitting on the manifold to catch the water sample.
TDS can be measured with an electronic TDS meter. PN 66760

Installing an RO to Service Other Water Using Appliances

Pressure, Pressure, Pressure
If you are installing a service line from an RO storage tank to an appliance with a minimum pressure requirement then you may need to consider the following options so as not to operate below the operating limits of that appliance.
Installation of a booster pump (92325)
Placing this pump before the RO will increases overall pressure to the system. If you boost the water pressure from 40 to 80, then the full pressure in the storage tank will be around 53 psi. Increasing the overall pressure in the system will allow more volume to be drawn from the tank before the pressure dips below a shutoff value.

ADDITIONAL POINT OF USE CONNECTION (Fittings and tubing for additional point of use connection is not supplied with this system)
NOTE: Icemakers typically use 1/4” tubing as feed line.
NOTE: Reduce the 3/8” Line to 1/4” as close as possible to the additional point-of use device to minimize flow loss.

1. To connect an additional point of use (icemaker, extra faucet in wet bar and/or another use for treated water), place a “tee” connector (P/N PP30121208W) in 3/8” blue line between faucet and RO Module.
2. Connect “tee” to point-of-use with 1/4” tubing (P/N 92600). Connect tubing to point-of-use. If point of use connection requires 3/8″ fitting, use of 3/8″ Tee (Part # 92403) and 3/8″ tubing (Part # 87600)

Service and Maintenance

Service Schedule
To keep the Aqua Flo system operating properly, it is necessary to change the filters and sanitize the system periodically.
Typically, this should be done on an annual basis. Service frequency may vary depending on local water conditions. High sediment, chlorine, turbidity, or hardness levels may require more frequent service. Use the following as a guide.
As needed
Clean the faucet with a soft cloth, avoid abrasive cleaners.

*Drinking Water System Sanitization Kit Preparation – 42903015
Place some rags or a towel below the system as some water may leak during this procedure. Have a pail handy to drain water into.

1. Shut off the water supply to the system at the adapter valve. Open the faucet and allow the system to drain completely  Shut off the faucet once drained.

2. Disconnect all 4 cartridges and replace them with the blank cartridges included in this kit. Disconnect the inlet line from the system and drain excess water into a pail.
   NOTE: if sanitizing an RO be sure to insert the blank RO cartridge (3 o-rings) in stage 3.

3. Add either ½ teaspoon of household bleach or 1 packet of Sani-System Liquid Concentrate (#50036) to the clear sanitization cartridge and seal the cartridge tightly.

4. Using the tubing included in the kit, connect the sanitization cartridge between the adapter valve and the inlet port on the system.

5. Turn on the water at the adapter valve.
   If sanitizing an RO allow the system to fill the tank for 30 minutes. Next, turn on the faucet and allow the system to run for 30 minutes.

6. Leaving the faucet open, shut off inlet water and let the system drain completely.

7. Disconnect the sanitization cartridge from the inlet line and system. Reconnect the inlet line to the system and replace cartridges on system.

8. Turn on the inlet water and check for leaks. If sanitizing an RO, allow the tank to fill for 30 minutes and discard the first tank. Allow tank to refill for 30 minutes.
