Notes
1. See the “Performance & Technical Information” section for all
applications where TDS exceeds 1000 ppm. A booster is strongly
recommended to improve the reduction of TDS. Higher pressures
will help maintain the membrane’s maximum rejection performance.
2. The reverse osmosis membrane used in these systems may be
damaged by chlorine. These systems include activated carbon
filters which protect the membranes by reducing chlorine. Influent
chlorine should not exceed 3 mg/L.
3. A softener is strongly recommended for water over 10 gpg hard.
Installing a system without a softener on water with hardness higher
than 10 gpg will reduce the life of the membrane.
4. Additional information on factors that affect RO performance can be
found in the “Performance & Technical Information” section.

This manual covers the technical aspects of Culligan®Aqua-Cleer®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. See Performance Data Sheet
(located in the Owners Guide) for exact percentages of contaminant removal.
System Configuration
The 4-Port manifold system is designed with the flexibility to allow for multiple filter and membrane configurations.
Packaging
The Aqua-Cleer system is shipped from the factory in cartons:
Warranty
A limited warranty is extended to the original end user from Culligan. This warranty is printed on the back cover of the Owner’s
Guide.
Application Guidelines
The Aqua-Cleer 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.
High Efficiency Operation
The Aqua-Cleer system has an option high-efficiency operation. Soft water use is strongly recommended. For maximum RO
membrane life on all hard-water installations, substitute the flow control as described in the “In-Plant Preparation” section of
this manual.

6 Culligan®Aqua-Cleer®Technical Manual
Manifold/Main Filter Assembly (Refer to Figure 2 for component description.)
• Manifold Assembly (#1)
The manifold assembly serves as the functional hub of the Aqua-Cleer system by directing the flow through each of the
system’s main components.
• Particle Filter (#2)
The particle filter (2) is melt blown and is closed at one end. The particle filter screens out particulate material, such as
dirt, sand, or rust, which may clog the other filters in the system. The filter is available in either SED 1, SED 2, SED 3.
• Activated Carbon Filter (prior to Reverse Osmosis Membrane - #3)
The activated carbon filter (3) is offered in two styles, granular or block. Both are rated to treat 2000 gallons of water
containing 2.0 ppm of chlorine. The active material is acid washed activated carbon. The activated carbon filter reduces
chlorine which may damage the RO membrane filter. It must be regularly checked and or replaced to prevent premature
membrane failure.
• Reverse Osmosis Membrane (#4)
The RO membrane (4) reduces dissolved substances and other microscopic impurities such as arsenic, lead, sodium,
and others. 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
concentrate stream.
The RO membrane featured in the Aqua-Cleer 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.
• Flow Control Assembly (#7)
The flow control assembly or concentrate flow control (7) regulates the flow rate of the flushing (concentrate) stream and to
maintain pressure in the RO membrane filter. It is located at the bottom of the reverse osmosis element. The assembly can
be adjusted to change the rate of the concentrate stream. The substitution procedure is on page 10.
• Automatic Shutoff (#8)
The automatic shutoff (8) automatically stops the flow of water through the Aqua-Cleer system when the storage tank
is full.
• Storage Tank
The storage tank (10) 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.
• Polishing Filter
The polishing filter (6) adsorbs any residual tastes and odors just before the water is delivered through the faucet.
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. Culligan highly recommends
discarding the product water for a full 24 hours to flush the preservative and to properly hydrate the membrane for
maximum performance. The flushing procedure is on page 10.
Note: Changing the flow control voids the NSF listing. Remove the NSF data label from the system if you adjust the
flow control. Changing the flow control voids the California Department of Public Health Certifications.

• Aqua-Cleer Sentry™Monitor
This optional monitor (figure 1) accessory checks the TDS level of the drinking water each time the dispenser faucet is
used. A green LED indicator mounted in the faucet signals if the TDS level is below the setpoint, an red signal appears if it
is above.
• Dispenser Faucet (#9)
The Aqua-Cleer faucet (9) allows the product water to be
drawn from the system with a simple rotation of the handle. It
features a built-in siphon break for concentrate discharge as
required by most plumbing codes.
To help assure quick and trouble-free installation of the Aqua-
Cleer®system, the preparation steps should be performed
in the dealer facility. Cleanliness is essential in the In-
Plant Preparation procedure. Be sure to wash your hands
thoroughly before handling filters. The use of surgical gloves
is strongly recommended.
Figure 1
Component Description 7

Tubing Connectors
The Aqua-Cleer®system features reliable and convenient push-to-connect (figure 3) 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. Culligan recommends
that the tubing listed in the “Suggested Installation
Equipment” section of this manual (page 3) be used with
the Aqua-Cleer system.
Filter Assembly Preparation
Activated Carbon Filter
The activated carbon filter must be thoroughly
flushed to remove carbon dust which can plug
the manifold or RO membrane.
To perform this procedure, it is necessary to use
a clean single head cartridge assembly.
1. Install 1/4” tubing to the inlet and outlet
of the single head cartridge assembly
(figure 4).
2. Install the activated carbon cartridge into
the single head cartridge
assembly (figure 5).

3. Connect the inlet of the single head cartridge assembly to a source of clean,
filtered water.
4. Connect the outlet of the service housing to a suitable drain.
5. Slowly turn on the water and flush the filter for 5 minutes at a rate of 1-2
gpm (4-7 L/min). Turn the water on and off several times during flushing to
help loosen carbon particles from the filter.
6. Once flushed, the filter should be placed in service within 24 hours.
7. Remove the activated carbon filter cartridge from the service housing and
set it aside in a clean location for installation into the Aqua-Cleer system.
8. Reattach protective cap.
Sanitize Manifold Assembly
The Aqua-Cleer system may be sanitized with either sanitizer packet, 5-1/4%
liquid chlorine unscented bleach or sanitizer.
Note: The storage tank should also be sanitized at this time.
Pour two tablespoons liquid chlorine bleach into the sanitizer cartridge
(figure 6A).
Assemble the cartridge to the 1st position in the manifold.
Using 1/4” OD plastic tubing, connect the inlet of the system (figure 7) to a
source of clean filtered water (RO or DI water, if available).
Connect 3/8” OD plastic tubing from the product water outlet to a 3/8” Tee.
Connect the other ends of the Tee to the storage tank and 3/8” shut-off.
Install bypass plugs in the remaining cartridge positions (figure 6B).
Turn on the supply valve, open the tank valve and 3/8” shut-off valve and
allow the system to fill with water.
Once water begins to flow from the shut-off valve, turn off the supply valve
and close the shut-off valve.
Allow the system to sit for ten minutes.
Turn on the supply valve and flush the sanitizing solution from the system.
The water coming from the storage tank should have a chlorine odor. If not,
repeat steps 1-9 until it does.
Fill and empty the tank (steps 3,6,9) until only a faint chlorine odor remains.
The polishing filter will remove any residual chlorine taste once the system
is installed.

Replacing the Flow Control
The concentrate water flow control is shipped with the reverse osmosis cartridge
(it is taped to the cartridge). Follow the procedure below to install the flow control:
1. Insert the flow control into the inlet of the ¼” concentrate tubing.
2. Insert the tubing into the elbow located at the bottom of the reverse osmosis
cartridge (figure 8).
The Aqua-Cleer system is designed for a 35% recovery. For maximum efficiency
on most softwater installations the standard flow control assembly can be
replaced with a 50% recovery flow control assembly. Use the 25% recovery
flow control assembly on high hardness and/or high TDS. Follow the above
procedure to replace the flow control.

Note: The same white flow control is used for the Aqua-Cleer 50 at 25%
recovery and Nanofilter.
Note: Changing the flow control, shipped within the unit, voids the NSF listing. Remove the NSF data label from the system
if you adjust the flow control. Changing the flow control voids the California Department of Public Health Certifications.
Flush RO Membrane
The RO membrane must be flushed prior to use.
1. Turn on the supply valve to the system.
2. Allow the product water and flushing water to flow to a suitable drain for 24 hours.
3. Reattach protective cap.
Check Performance
Check the performance of the system according to the procedure beginning on page 21 of this manual.
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.
* Cartridge not for sale in California or Iowa.
10 Culligan®Aqua-Cleer®Drinking Water Systems
Figure 8

In-Plant Preparation 11
Check Air Pressure
Using a tire gauge with 1 psi increments, check the air pressure in the empty storage tank. The air pressure should be between
5 and 15 psi, for the 2, 3 and 9 gallon storage tanks. Depending on the influent water pressure the air pressure may need to be
adjusted. Refer to page 25 to determine the optimal air pressure setting. To modify the air pressure use a bicycle-type hand
pump to increase the air pressure or depress the stem of the air valve to decrease the pressure.
Install Tank Shut-off Valve
Use a high quality, food-grade thread sealant or PTFE tape to assemble the valve onto the tank.To avoid future leaks, do not
over tighten the plastic valve onto the tank.
Sanitize the Storage Tank
The storage tank must be flushed and sanitized prior to installation. See page 9 for sanitization procedure.
Fill the Storage Tank (optional)
So that your customers can begin using their new Aqua-Cleer system immediately upon installation, you may wish to fill the
storage tank with RO product water. Once the in-plant preparation of the Filter Assembly (prior section) is complete, proceed
as follows:
Warning! Do not use the tank ball valve to lift or carry the tank.
1. Connect a length of 3/8” OD plastic tubing between the tank ball valve and the product water fitting (figure 9) on the
manifold.
2. Using 1/4” OD plastic tubing, connect the system inlet to a water source meeting the characteristics listed in Table 1.
3. Using 1/4” OD plastic tubing, connect the concentrate outlet to a suitable drain.
4. Turn on the water supply, open the tank ball valve, and allow the tank to fill (3-4 hours).
5. Once the tank is full, close the tank ball valve and disconnect the system so that it can be transported to the
installation site.
Polishing Filter Preparation
The polishing filter must be flushed prior to use to remove any carbon dust generated during shipment.
1. Using 3/8” OD plastic tubing, connect the inlet of the filter to a source of clean filtered water (RO or DI water, if available).
Observe the direction of flow arrow on the filter.
2. Turn on the water supply and flush the filter for 5 minutes. Cycle the water on and off approximately 10 times during the 5
minute flush.
3. Turn off the water supply, disconnect the filter, and set aside for final installation.
4. Once flushed, the filter should be put into service within 24 hours.

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 9) must be observed.
The Aqua-Cleer 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 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 concentrate line that leads to the faucet should be
installed in a straight vertical path to avoid making a gurgling noise.

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 corresponds to the customer’s water supply.
• Important considerations:
• Access to the bottom (undersink) 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 undersink 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 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. For undersink installations, the cold water faucet line can
usually be tapped.
Note: Follow all local plumbing codes when connecting to service water.

14 Culligan®Aqua-Cleer®Drinking Water Systems
• 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, PN 01016259
(figure 10).
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 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.
Clear and Prepare Area
Since this product is more likely to be installed within the customer’s daily living space than other water conditioning products,
the installation area should be kept neat and clean. If possible, consult with the customer as to how the installation site is used.
Faucet Installation
The Aqua-Cleer drinking water faucet was designed by Culligan to compliment the RO drinking water system. Properly
installed, it will help to maximize your customer’s product satisfaction. 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.
Sink Drilling Instructions

• Select the proper faucet location.
• Center punch hole to provide a starting point for your drill.
• Drill a 1/2-inch hole to accept the shank of a 1-1/4-inch Greenlee Hole Punch.
• Insert the punch. Cut the hole by tightening the drive screw.
• Remove any roughness with a file and clean up metal chips.
Porcelain Enamel Sink
Follow these basic guidelines when drilling a porcelain sink:
• Penetrate the porcelain to the base material.
• Protect the surrounding porcelain material
• Use the appropriate tool to drill the base material.
Figure 10
Note: Follow all local plumbing codes when connecting to service water.
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.

One proven tool is the Relton porcelain cutter kit, PN 00-5916-25, 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.
• 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.
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.

Assembly
Base Installation
1. The faucet will separate from the base with a 1/4 clockwise turn. This will allow for you to do all of the mechanical
installation of the faucet from the top of the sink (see figure 11).
2. Center the gasket over the 1-1/4” sink hole. Place the faucet base on top of the gasket and push the toggle bolts through
the sink hole.
3. Center the base over the hole with the Culligan logo facing forward and tighten the screws in a clockwise rotation.
4. You may need to use your finger to guide the toggles as you tighten the screws. Once the screws are tightened and
seated the base installation is now complete.
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. Run some warm water over the
end of each tube and push them onto the selected barb fittings.
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.
4. Feed the monitor cable, if used, down through the faucet base. Be sure that all twists are eliminated from the cable.
Final Installation
1. You will find two handle selections with the faucet. Choose one and install it by removing the screw and slipping the handle
into place (see figure 11).
2. You are now ready to install the faucet into the base assembly that is mounted on the sink. First guide the tubing into the
center of the base assembly and feed them through until the faucet reaches the base.
3. Decide if you want the handle to be on the left or right side. Hold the base securely with your free hand and insert the
faucet into the base and turn it clockwise 1/4 turn. Insert the locking pin.
4. Once the faucet is securely attached to the base the installation of the faucet is complete.
5. Next step is to attach the tubing to the RO system and the drain connection according to the normal installation instructions
for the RO system.
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.
Caution! Plastic Parts will break if screws are over tightened!
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.

Changing Handle Orientation
1. The handle can be rotated 180°. Listed below is the procedure to change the handle orientation (refer to figure 11):
2. Remove the handle cap and unscrew the handle screw.
3. Remove the handle.
4. Unscrew the handle cartridge nut.
5. Remove the handle cartridge and rotate it 180° making sure the notches on the cartridge line-up with the notches on the
faucet housing.
6. Reverse the procedure for reassembly.
Cleaning the Faucet
Wipe the faucet with a soft cloth, avoid abrasive cleansers.
Provide Inlet Water Supply
A wide variety of plumbing circumstances and choices exist to provide the feed water supply. The first connection in the system
is at the prefilter where a 1/4-inch connection is supplied. The supply water plumbing should therefore terminate in a 1/4-inch
tube fitting. Copper tubing or galvanized iron pipe is the typical plumbing used in most homes.
Piercing (Saddle) Valve
A special piercing valve (Figure 12), is available which makes its own hole as it is
tightened down.
Installation 17
Note: Check with local plumbing codes to verify that piercing valve
is allowed.
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. Figure 12

Connecting Aqua-Cleer®System Drains
Plumbing codes require that the drain from reverse osmosis drinking water systems be discharged through an air gap siphon
break. The Aqua-Cleer 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.
The air gap feature of the Culligan®faucet requires standard 3/8” tubing.
Connections to undersink plumbing can be made with a saddle clamp designed to accept
the drain tubing from the faucet. Culligan offers a saddle kit, PN 01-0003-29, designed
for 1-1/2” undersink drain plumbing (Figure 13). 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.
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 Culligan
recommends 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.
Reservoir Tank Placement
Place the reservoir tank in the location previously selected.
