Precautions

WARNING: Do not use with water that is microbiologically unsafe or of

unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.

CAUTION: Filter must be protected against freezing, which can cause cracking of

the filter and water leakage.

CAUTION: The rubber o-ring provides the water-tight seal between the cap and

the bottom of the housing. It is important that the o-ring be properly seated in the groove below the threads of the housing or a water leak could occur.

CAUTION: Because of the product’s limited service life and to prevent costly repairs

or possible water damage, we strongly recommend that the bottom of all plastic housings be replaced every ten years. If the bottom of your housing has been in use for longer than this period, it should be replaced immediately. Date the bottom of any new or replacement housing to indicate the next recommended replacement date.

NOTE:

• For cold water use only.

• Make certain that installation complies with all state and local laws and regulations.

• The contaminants or other substances removed or reduced by the selected cartridge are not necessarily in your water. Ask your local water municipality for a copy of their water analysis, or have your private well tested by a reputable water testing lab.

• After prolonged periods of non-use (such as during a vacation) it is recommended that the system be flushed thoroughly. Let water run for 5–6 minutes before using.

• The filter cartridge used with this system has a limited service life. Changes in taste, odor, color, and/or flow of the water being filtered indicate that the cartridge should be replaced.

• Some harmless bacteria may attack cellulose media cartridges (such as the D-

10). If your cartridge seems to disintegrate or develops a musty or moldy odor, switch to a synthetic media cartridge or call Technical Support.

The US-550 is Tested and Certified by NSF International to NSF/ANSI Standards 42/53 with cartridges D-10, D-20, D-30 and D-40. See Performance Data Sheet in Manual for specific claims.

Contains built in flow control at 0.6 gpm (2.3 Lpm). For use with separate faucet (FT-10) in under-sink installations. NOTE: Substances reduced are not necessarily in your water. Filter must be maintained according to manufacturer’s instructions, including replacement of filter cartridges.

Installation

NOTE:

• For standard under-sink installation on 3/8-inch (10 mm) cold water line (copper or PVC pipe).

• Please read all instructions, specifications, and precautions before installing and using your water filter.

• Install filter cartridge in housing before proceeding with installation (see Filter Cartridge Replacement on page 3).

• Numbered diagrams correspond with numbered steps.

1. Prepare Area and Adapters

(A) Turn off cold water supply and open nearest faucet to release pressure in pipes before

starting installation. Place a tray or towel under the cold water line to catch excess water.

(B) Apply about 3–4 inches (76–102 mm) of Teflon

tape in clockwise direction to pipe

threads of each adapter.

2. Attach Mounting Bracket

Using the self-tapping screws, attach mounting bracket to cap, then mark location under sink where filter is to be mounted.

NOTE: Allow 1-1/2 inches (33 mm) under filter to enable filter cartridge changes.

3. Attach Pipe Adapters to Filter Cap

Start connector into inlet on filter cap by hand. Using an adjustable wrench, tighten connector firmly. DO NOT OVERTIGHTEN. About one thread should remain visible. Repeat for outlet on filter cap.

Mount filter in marked location with mounting bracket.

4. Attach to Cold Water Line

(A) Using a pipe cutter or hacksaw, remove a 3-inch (76 mm) section of pipe from the cold

water line. Deburr ends of remaining pipe with a file.

(B) Disassemble nuts and ferrules from compression elbows. Install a compression elbow onto

each end of remaining cold water line as shown. Using two wrenches, tighten compression nuts firmly.

NOTE: Use metal ferrules with copper pipe and plastic ferrules with plastic pipe.

5. Installing the Tubing

Determine the lengths of tubing needed to connect the inlet and outlet sides of filter to the compression elbows on the cold water line. Measure tubing short enough to prevent kinking. Assemble as shown. Using two wrenches, tighten compression nuts 1–2 turns.

6. Completing the Installation

Turn on the water supply to allow filter to slowly fill with water and then press the red pressure-relief button on top of the housing to release trapped air. Check for leaks and tighten as needed.

NOTE: A drinking water cartridge may contain carbon fines (very fine black powder). After installation, flush the cartridge for 5 minutes before using the water. It is recommended that you run the tap at least 20 seconds prior to using the water for drinking or cooking purposes.

Filter Cartridge Replacement

(A) 1. Turn off water supply to filter.

2. Depress red pressure-relief button on top of filter.

3. Unscrew and remove bottom of housing.

(B) Locate and remove large o-ring, wipe clean of lubricant and set aside. Discard used cartridge.

Rinse out bottom of housing and fill 1/3 full with water. Add about 2 tablespoons of bleach and scrub cap and bottom of housing with non-abrasive sponge or cloth. Rinse thoroughly.

Lubricate o-ring with clean silicone grease. Insert o-ring back into groove and smooth into place with finger.

NOTE: This step is important to ensure a proper housing seal. Make certain o-ring is seated level in the groove.

Insert new cartridge over standpipe in bottom of housing. Cartridges with one gasket should be inserted with the gasketed end towards the threads of the housing. (gasketed end would point upwards if housing is mounted as shown in illustrations).

5. Turn on water supply slowly to allow filter to fill with water.

6. Depress red pressure-relief button to release trapped air. Check for leaks before leaving installation. NOTE: A drinking water cartridge may contain carbon fines (very fine black powder). After

installation, flush the cartridge for 5 minutes to remove the fines before using the water. You should run the tap at least 20 seconds prior to using the water for drinking or cooking purposes.

Troubleshooting

Leaks:

...between cap and bottom of housing:

1. Turn off water supply and press pressure-relief button. Remove bottom of housing.

2. Clean o-ring and o-ring groove (located directly beneath threads of housing). Lubricate o-ring with clean silicone grease and replace securely into groove. Screw bottom

of housing back on cap and hand-tighten. DO NOTOVER-TIGHTEN.

...on inlet/outlet connections:

1. Turn off water supply. For brass fittings, tighten nut snugly 1/2-turn with wrench.

2. Turn on water supply. If leaks persist, or if there are other leaks on system, turn off water supply. Call Technical Support at 1-800-645-5426.
