Carton Contents:

The LittleWell CT10 series Countertop Water Filter carton contains the following for assembly:

Base with Housing Cap & Spout

Filter Housing (10 in.)

Housing Wrench

Tubing (1/4 in. by 3 ft.)

Metal Diverter Valve with Faucet Thread Adapter (male to male)

Filter Cartridge in shrink wrap (2.5 in. x 10 in)

1.0 Installation:

1.1 Selecting a position for the filter

The filter is designed to be free standing on flat surfaces, such as countertops. WARNING: For cold water only.

1.2 Installing the filter cartridge

Wash and dry your hands thoroughly and ensure that any open cuts are covered to prevent contamination of the filter

cartridge and housing. Separate the filter cap and housing by unscrewing the housing in a counter clockwise direction

(when viewing from above). Observe the housing O-ring. Remove the shrink wrap from the filter cartridge.

**PLACE THE FILTER WITH THE BLACK CARBON SIDE POINTING DOWN**

Place the center hole of the black carbon end of the filter cartridge into the housing cap (Please ignore the “This side

up” text on this end, which is intended for the undersink model). While making sure the O-ring is in place, screw the

housing back on by turning it in a clockwise direction. Hand tightening is typically enough, but you can use the housing

wrench to turn it an additional 1/4 to 1/2 of a turn if necessary. Do not over tighten the housing, as this can make future

cartridge replacements difficult.

1.3 Connecting the tubing and diverter valve to kitchen faucet

Remove the aerator from the kitchen faucet. If the faucet is left with a female thread, screw in the included male to male

thread adapter in place of the aerator, then screw the diverter valve into the adapter. The male to male adapter can

typically be hand tightened, but you can use a hex screwdriver or another available tool to tighten it further if needed. If

your faucet already has a male thread, simply screw the diverter valve directly onto the faucet. On the diverter valve,

remove the nut from the 1/4” knob and slip it onto the tubing. Then push the tubing onto the knob, and tighten the nut down to create the seal. 2.0 Conditioning the Filter The filter should now be ready to fill with water. To avoid any problems caused by airlocks in the filter housing, the unit should be held upside down over the kitchen sink. Partially turn on the cold tap, then pull the valve stem on the diverter valve to allow the water to gently fill the unit for the first time. Check for leaks.

.0 Use of the Diverter Valve The diverter valve allows filtered water to be drawn off from the spout of the filter by pulling the diverter valve stem. The valve stem automatically returns to the unfiltered setting, allowing the water to be directed to the kitchen faucet so that each filter is preserved for its intended use. 4.0 Servicing the Filter - Changing or Cleaning the Filter Cartridge During use, the flow rate will deteriorate and the filter cartridge will change color.
