Precautions
WARNING! Follow all precautions indicated in the manual provided with the Culligan water
treatment system.
WARNING! For systems using a booster or distribution pump, the pressure of the treated water
cannot exceed the pressure of the cold water supply.
WARNING! Reducing the Booster pump pressure below incoming pressure will allow the proper
operation of the ClearLink.
WARNING! For cold water use only. Do not use on hot water line.
CAUTION! Control box must be protected against freezing temperatures, frost, snow, sleet and
ice. Exposure to these can produce cracks and product failures.
CAUTION! The Filter/RO should be flushed before installing into the system to ensure the proper
operation of the ClearLink.
CAUTION! This product has a limited service life. We recommend that a record be kept regarding
the date of install and any other performed maintenance. Because of the product’s
limited service life and to prevent costly repairs or possible water damage, we
strongly recommend that the control box be replaced every ten years.
• After prolonged periods of non-use (such as during a vacation) it is recommended that the system be flushed
thoroughly. Let the filtered water run for 5-6 minutes at 1.6 gpm before using.
• The ClearLink estimates filter life based on flow and time. Changes in taste, odor, color and/or flow of the filtered
water could indicate that the filter(s) should be replaced.
• Make certain that installation complies with all state and local laws and regulations.

Setting Capacity and TDS Function (All Models)
NOTE This section does not apply to Aquasential ClearLink PRO
Find the dip switches on the front of the circuit board. SW2 and SW3 set the time and capacity for the filter reminder.
Default settings for the dip switches are TDS ON, 1000 gallons and 365 days.
• SW1: Enables/Disables the TDS function (Enable only for RO systems). The system will measure the difference between
the feed and product water to determine if the RO is working. If installing an RO system with a Mineral Boost cartridge, this
feature may need to be disabled so that the alert indicator does not illuminate prematurely for RO membrane replacement.
• SW2: Filter capacity in gallons.
• SW3: Filter capacity in days.
• SW6: Used for production testing and should be left in the off position.
If dip switches are changed from the default positions, you must press and hold the RESET button to
ensure filter capacity is counted correctly.

NOTE No combination of SW2 and SW3 positions will disable either setting . The alarm and/or notification
for filter replacement will always alert based on whichever capacity setting is reached first.
Therefore, it is also not possible to force the system to only alert based on ONE setting.

12 Culligan®ClearLink 12 Cat. No. 01033136
Installation (All Models)
NOTE If using an external flow switch, install the external flow switch before installing the
ClearLink. See "External Flow Switch for a Secondary Outlet" on page 16 for instructions.
NOTE Refer to the manual provided with your filter/RO for installation instructions specific to that system.
NOTE Some installations may require adapters and fittings not included with the product.
Review the manual and your installation before beginning.
NOTE Consult your local plumbing codes and install accordingly.
1. Turn off both hot and cold water
shut-off valve then turn on the
kitchen faucet and allow all
water to drain from line.
2. Disconnect the cold water line from the
cold water shut-off valve.
NOTE If rigid plumbing pipe (metal or plastic)
is used, you may need to shorten the
pipe using a hacksaw or pipe cutter to
accommodate the control box.

Installation 13
Cat. No. 01033136
NOTE The control box must be in a vertical position.
NOTE If space does not allow for mounting the control box onto the valve, it can be mounted on a wall
and connected using flexible lines. (purchased separately).
NOTE Flare fittings used on cut-to-fit PEX line prevent the connecting nut from being threaded on more then
1-2 turns. Therefore, it is recommended that the MS031611 adapter listed in the “Installation Fittings and
Replacement Parts List” section be used. The flare fitting of the PEX line should be cut off and the tubing
inserted directly into the push-to-connect end of the MS031611 adapter.
NOTE All filters and RO membranes should be flushed before connecting any ClearLink device to the
filtration/RO system.
NOTE The port marked “RO/Filter” is plugged for remote system installations (Water supply is not the
same as the sink such as basement installations). This port is normally plugged when installing
the filtration/RO system in a location other than the kitchen cabinet.
NOTE Use the supplied adapter if your system uses a 1/4” tube.
3. Connect the control box to the cold water shut-off valve
and the water line to the Faucet as shown. Culligan
recommends 1/2 - 3/4 additional turns past finger-tight.
CAUTION! The stationary hex nut on the outlet
of the ClearLink should not be used
to over-tighten the hose fitting.

NOTE If the customer has a garbage disposal,
connect the RO drain line coming
from the air gap to the “auxiliary” port
(removable plug where a dishwasher
drain is typically hooked up) rather than
downstream of the disposal. The high
flow rate from a disposal sucking water
from a clogged sink will send water up
and out of the air gap.
