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 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.

SW1:  OFF = Disabled    ON = Enabled  
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:  OFF = 500 gallons  ON = 1,000 gallons
SW3:  OFF = 180 days    ON = 365 days
SW6 is used for production testing and should be left in the off position.

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.

Problem Solution
Leaks at filter/RO Inlet or outlet connection A rolled o-ring can block the tube from fully inserting. Use small 
screw driver to reseat the o-ring and then confirm that the end of 
the tubing has a clean, square cut.
Low filtered water flow/system returns to unfiltered 
flow automatically:
Low flow rates may not activate the control box electronics. Refer 
to your system manual to trouble shoot a low flow condition.
Button is communicating, but no change in flow. Confirm that the bypass valve is in the down/closed position.
Button communication is intermittent. Some materials may block the wireless signal more than others. 
Try moving the button to an area on the counter that is closer to 
the under-sink control box.
Filtered water flow won’t turn off. Low batteries for the control box can cause the system to be 
stuck in the filtered position. The bypass valve can be used to 
allow unfiltered water flow to the faucet while the issue is being 
corrected.
