About Your
System
Thank you for choosing a Culligan Aqua-Cleer advanced drinking water system. Your new system is designed to bring you years of deliciously crystal-clear Culligan water. The best part is it comes right from the tap. No more lugging around bottles or waiting for pitchers to slowly fill up. With your continuous supply of great tasting water, not only can you get your 8 glasses a day but you can easily use it for cooking, coffee, juice, baby formula, ice cubes, anything you use water with.
The important thing to remember is to change out your filters on a regular basis. The quality of your water is only as good as the quality of your filters. Each filter is designed to last for 1,000 gallons (roughly 12 months). Membranes will last longer if used with pre-filtration. A flow monitor is available with your system to let you know when you have consumed 1,000 gallons of water through your system. If you did not purchase one with your system, you may consider asking your Culligan man about having one installed.
Faucets with reminder lights are also available.

Purpose of each level of filtration:
Pre-Filtration:
Pre-filtration for this system is used to reducing large contaminants from the water before they reach either the reverse osmosis or nano filtration membrane. The use of pre-filtration cartridges helps extent the membrane’s life. There are two types of pre-filtration available with this system: sediment filtration and carbon filtration.
Sediment Filtration:
Sediment is defined as sand, dirt, silt, fine sand and or coarse sand that can be found in many water supplies.
Carbon Filtration:
Carbon is used to reduce chlorine taste and odor. Most people often describe this taste as being slightly chemical or they equate their drinking water to that of the local pool. Municipalities use chlorine to disinfect the water on the way to your home. This is a necessary step to delivering safe water to your home but depending on the level of chlorine by the time it reaches your home the taste of your water may be unpalatable.
Membrane Technologies:
The Aqua-Cleer reverse osmosis membranes utilize a tightly woven membrane that acts as a barrier to contaminants. Water is pushed up against this membrane at pressure. Depending on the weave of the membrane only a certain percentage of contaminants can pass through. Reverse Osmosis can reduce up to 99% of contaminants.
Advanced Filtration:
The advanced filtration cartridges are specifically designed to reduce contaminants that reverse osmosis membranes are not efficient in removing.
Total Defense:
The Total Defense cartridge should be added to your system to deal with lead, mercury, aesthetic chloramines, aesthetic chlorine taste and odor, cysts, Volatile Organic Compounds (VOC) and MTBE.
• Chloramines have a stronger taste and are more difficult to remove than chlorine.
• Mercury is a toxin that can cause kidney damage.
• Lead is a toxin that can cause kidney problems or high blood pressure in adults and developmental problems in children.
• Cysts are a common cause of health issues. They can be found in some municipal water sources but more often found in wells under the influence of surface water.
• VOC is a name given to a wide range of organic contaminants, some are known to be carcinogenic.
• MTBE was used in gasoline to reduce emissions and is considered harmful.
Mineral Boost
The Mineral Boost cartridge adds healthy amounts of natural calcium minerals back into reverse osmosis water to create amazing tasting, optimally alkaline, pH balanced water. Benefits include:
• Raises RO water TDS by 20 ppm to 30 ppm
• Raises RO water pH by 1 to 2 pH

Arsenic:
Arsenic (As) is found naturally in some well 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 result from your water utility. If you have your own well, you can have the water tested by an accredited lab. The local health department or the state environmental health agency can provide a list of certified labs. Culligan International is one such lab. For more information please contact your local Culligan dealer. For additional information about the arsenic in water can be found through the EPA’s website at www.epa.gov/safewater/arsenic.html.
There are two forms of arsenic: pentavalent arsenic (As (V)) and trivalent arsenic
(As (III)). Special sampling procedures are needed for a lab to determine what type and how much of each type of arsenic is in the water. In well water, arsenic may be pentavalent, trivalent, or a combination of both. Reverse osmosis membranes are effective at reducing pentavalent arsenic but not trivalent arsenic. The Arsenic specific cartridge was specifically designed to reduce trivalent arsenic.

NOTE Install the drain line 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. The 1/4” concentrate line that leads to the faucet should be installed in a straight vertical path to avoid making a gurgling noise. For installations in Massachusetts: 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.
This owner’s guide provides visual assembly reference only. Since specialized skills are required in the assembly of the drinking water system, we recommend that you contact your local independently operated Culligan dealer to complete this installation.
Select Component Installation Locations
Dispenser Faucet
The Culligan® 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 minimum 1-1/4” diameter hole is required. When installing the Aqua-Cleer® water quality monitor, refer to the installation instructions packaged with the monitor. Make certain the TDS level and/or gallons setting correspond to the desired water supply.

01020485
Important considerations:
• Access to the bottom (under sink) of the faucet is required for attachment of product water line.
• The faucet can be installed for left- or right-handed operation.
• There should be no under sink obstructions which would prevent smooth tubing runs to the drain connection, carbon post-filter, 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 or 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. For under sink installations, the cold water faucet line can usually be tapped.
The Reservoir Tank
Position the reservoir tank near the faucet for optimum customer convenience. The standard and medium reservoir tank will weigh about 28 pounds (13 kg) when full of water, so it must be positioned on a stand or held securely by the optional mounting bracket. The reservoir operates best in the vertical position, but it will operate on its side. However, air will not escape readily and foaming may occur at the faucet nozzle. This should be explained to the customer prior to installation.
Drain Connection
The most convenient entry to the drain is directly above the P-trap of the kitchen sink. However, the concentrate 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. See plumbing diagram on page 7 for proper air gap installation to waste connection.
Installation of Filter System Assembly
The mounting bracket contains three mounting slots. The holes are sized to accept #10 round head wood screws (not 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.
Install Filter Cartridges
1. Lightly lubricate the cartridge O-ring with silicone lube and insert the sediment filter cartridge into the manifold.
2. Twist the cartridge to lock it into the manifold.
See Figure 2.
Locked
Position
Unlocked
Position
Figure 2.
3. Repeat steps 1-2 and install the flushed activated carbon filter cartridge into housing and the RO membrane element. Be sure the drain adapter is in place.
NOTE 1) The RO cartridge must be inserted into the 2nd, 3rd, or 4th position on the
RO manifold.
NOTE 2) If only three cartridges are to be inserted into the manifold, the bypass
plug cartridge must be inserted in the 4th position. See Figure 3.
NOTE The activated carbon, reverse osmosis, and polishing filter cartridges must be conditioned as follows prior to installation into the Aqua-Cleer system. Your
Culligan man will do these important procedures at the time of purchase.
• Activated Carbon Cartridge - 10 minute flush to remove carbon dust
• RO Membrane - Minimum 24 hour flush to remove preservative solution
• Polishing Filter - 10 minute flush to remove carbon dust
• Mineral Boost Cartridge - 10 minute flush to remove mineral particulates
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 exceed 120 psi, the maximum operating pressure of the Aqua-Cleer 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 Culligan’s published standards. Temperature does not affect the concentrate flow rate.
Figure 3.
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 plug 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.
01020485

01020485
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 macroporous 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.
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 Aqua-Cleer 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 Aqua-Cleer is manufactured with a recovery rating designed to be around 30% -40%. Depending on temperature, pressure and tolerances the actual recovery value may be slightly different for each system.
To keep the Aqua-Cleer
®
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
It is recommended that you do the following annually:
(Contact your local Culligan dealer for replacement cartidges and maintenance)
1. Sanitize the System
2. Replace:
• Sediment Filter
• Activated Carbon Filter
• Polishing Filter
• Any Advanced Filtration Cartridge
• Mineral Boost Cartridge
3. Check:
• RO Membrane
• Flow control assembly
• TDS Reduction Performance
• Flow Rates (including air gap)
• Drain tubing for back-up
Perform the following steps in the order shown to sanitize your system
It is recommended to have your local Culligan dealer perform the sanitization process. Your local Culligan man has been specifically trained to test the water quality and efficiency of the system in order to determine when the RO membrane should be replaced and ensure the system is working properly.
Preliminary Steps:
1. Check for any leaks that may exist from tubing connections or the faucet.
2. Check for flow to the drain. If flowing, close tank shut-off so you can check auto shut-off operation
3. Test and record product TDS from faucet. Also observe if faucet stem is stiff to move.
4. Test and record feed TDS, and then calculate rejection percentage.
5. If rejection is acceptable - Shut off storage tank, remove tank supply tubing to collect and record product flow, and water temperature.
6. Record feed pressure if needed by attaching a pressure gauge to feed line. Use the recorded feed pressure and water temperature to check product flow rate against the supplied chart.
Membrane okay? Low production could be the result of partially plugged prefilters. If so retest after filters are changed.
7. With feed line off begin draining tank.
The Aqua-Cleer RO manifold assembly may be sanitized with 5-1/4% liquid chlorine unscented bleach.
1. Shut off water supply then remove all filters. Put bypass plugs in ports 2, 3 and 4.
2. Pour two tablespoons liquid chlorine bleach into the sanitizer cartridge and place in port 1.
3. Turn on the water supply valve and the RO faucet to allow the system to fill with water. Allow the water to flow through until the entire system for about 10 minutes or until the sanitizing solution is through.
4. Install new filters, including the post carbon filter, and membrane if needed, or reuse existing membrane. Some filters require flushing before use to remove dust
and fines. If an in-plant flush was not performed, use the single head assembly to perform this using the feed line and drain lines available. Don’t flush using the RO manifold.
5. Replace the battery in the quality monitor if applicable.
6. Discard the first glass of water from the faucet.
7. Thoroughly check for leaks.

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 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 - $30. Information about arsenic in water can be found on the internet at the US 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 arsenite). 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 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 Aqua-Cleer system is designed to remove pentavalent arsenic. It will not convert trivalent arsenic to pentavalent arsenic. The system was tested in a lab. Under those conditions, the system reduced 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 if the system is working properly.
The RO component of the Aqua-Cleer system must be replaced every 3-5 years to ensure the system will continue to remove pentavalent arsenic. The component identification and locations where you can purchase the component are listed in the installation/operation manual.
The system has been tested for the treatment of water containing pentavalent arsenic (also known as As (V), As (III), or arsenate) at concentrations of 0.050 mg/L or less. This system reduces pentavalent arsenic, but may not remove other forms of arsenic. This system is to be used on water supplies containing a detectable free chlorine residual 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 Fact section of the Performance data Sheet for further information.
Arsenic (As) is a naturally occurring contaminant found in many ground waters. It generally occurs in two forms (valences or oxidation states): pentavalent arsenic (also known as As(V), As(+5), and arsenate) and trivalent arsenic (also known as As(III), As(+3), and arsenite). In natural ground water, arsenic may exist as trivalent arsenic, pentavalent arsenic, or a combination of both. More information about arsenic and its toxicity can be found at the Agency for Toxic Substances and
Disease Registry Toxicological Profile on Arsenic website at http://www.atsdr.cdc.gov/toxprofiles/ phs2.html, and at the U.S. Environmental Protection Agency website at http://www.epa.gov/ safewater/arsenic.html.
Arsenic does not generally impart color, taste, or smell to water; therefore, it can only be detected by a chemical analytical test. Public water supplies are required to monitor delivered water for arsenic (trivalent arsenic plus pentavalent arsenic) and the results are available to the public from the utility. Consumers using private water sources will need to make arrangements for testing.
An arsenic test usually costs about $15-30, and it is recommended that the test be conducted by a certified laboratory. Local health departments or environmental protection agencies can help provide consumers with a list of certified laboratories. Some laboratories may also be able to analyze specifically for (speciate) the form(s) of arsenic present in a water sample if requested.

The Aqua-Cleer system with AS3 following an RO is designed to reduce arsenic: both pentavalent and trivalent forms of arsenic. This treatment system was tested under laboratory condition as defined in NSF/ANSI 53 Drinking Water Treatment Units - Health Effects and was found to reduce
[influent arsenic challenge concentration 0.050 mg/L] arsenic consisting of either pentavalent or trivalent arsenic in the test water to less than 0.010 mg/L, for [tested treatment capacity] gallons of delivered water, the life of the system under standard testing conditions. Actual performance of the system may vary depending on specific water quality conditions at the consumer’s installation.
Following installation of this system, the consumer should have the treated water tested for arsenic to verify that arsenic reduction is being achieved and the system is functioning properly.
The arsenic removal component of this system must be replace at the end of its useful life of 1,000 gallons. The replacement components, AS3, RO30, RO50 can be purchased from your local
Culligan dealer.
