Collection: Installation instructions UC-1


1. Find a convenient location under the sink on the cold water side to place the filter. The housing can be mounted to the side wall using the "L" bracket and screws.

2. The faucet should be secured through an existing hole in the sink ledge (such as an old sprayer) or a ½" hole can be drilled in the desired location. If you have a porcelain sink, you might consider having a professional do the drilling, or install the faucet into the countertop, back from the sink ledge. The small rubber gasket, chrome cover and large gasket (used when using larger hole - not needed when installing in 1/2" hole) go on the countertop side. Under the sink, install the metal washer, the lock washer, and then the brass nut, onto the faucet stud. Position the handle where it is convenient for you, and then tighten. Now install the gray quick-connect fitting on the end of the faucet stud - tighten securely. Attach the tubing to the "OUT" side fitting of the filter and then to the faucet fitting. The filter’s fittings are a special high-pressure quick-connect type. To connect, simply push the tubing into the fitting until it is completely bottomed. To disconnect, push down (towards filter) on the outer ring while pulling out on the tubing.

3. Next, install the "Angle Stop" valve adapter - see separate instruction sheet. Insert one end of the other tubing into the adapter end, and the other end into the "IN" side fitting of the filter.

4. Check all components for leaks.

5. Open the faucet and allow water to run for several minutes to flush out the normal black carbon fines (it will "sputter" until the air is worked out). Initially, the water may appear cloudy - this is due to tiny air bubbles and will clear up shortly. Pushing the faucet handle down gives you a controlled flow; flipping the handle up will lock it for filling pitchers, etc.





In virtually all cases, the taste and odor of chlorine will return to municipal water when the cartridge has lost its effectiveness. The enclosed test strips (2) can be used to confirm the presence of chlorine. Collect some filtered water into a cup. Dip the test strip into the water sample with a constant gentle back and forth motion for 10 seconds. Immediately note the color change: the pad on the end will turn blue with the presence of free chlorine, the pad nearest the handle will turn green with the presence of total chlorine (chloramines). IMPORTANT: Assess the color within 10 seconds after dipping the strip - the pads become unstable after that and will give a false reading. Additional test strips are available from Crystal Clear Supply (2 for $1.75). While this cartridge has been tested to effectively remove chlorine for about 6,000 gallon of water, the type and concentration of other contaminants varies widely throughout the country. Therefore, to assure maximum effectiveness and the best possible water quality, it is suggested that the cartridge be replaced at least once a year.

Our units are not warranted against sediment clogging. If the flow rate is significantly reduced, clogging is most likely the cause. Private well, cities with older distribution lines can have high levels of dirt and sediment. You can try to back-flush the unit by reversing the fittings on the housing to temporarily reverse the water flow. You can upgrade your unit to a double housing configuration with a disposable 1-micron sediment prefilter to prevent future clogging. Order part number CK-UCD.
