How To Install Your Countertop Water Filter

This is a simple process.

Start by removing the aerator from your faucet. (See Figure A at right.) Usually you can take it off with your fingers. If needed, use pliers.  It's a normal "right hand" thread.  Remove by turning counterclockwise. Save the aerator. If you move your filter later, you'll need it.

Next, simply screw the diverter valve on in place of the aerator. It will screw right on to most faucets without a problem. Be sure the black washer is in place in the diverter valve.  If the valve doesn't fit your faucet, use one of the adapters included with your filter. (See Figure B.) Probably it will be necessary to use one of the washers with the adapter.

Our picture (Figure C) shows a faucet that needed an adapter. The white adapter was screwed onto the faucet, then the diverter valve was attached to the adapter. Remember that in most cases you won't need an adapter; the diverter will attach directly to the faucet threads.

Locate the filter beside the sink, and when you're ready, turn on the cold water.  Start the filter (Figure D) by pulling out the small stem on the diverter valve. This will divert water through the filter.  When you first start the filter, there will be a considerable delay while the filter fills with water. Eventually, water will come out of the filter's spout. On subsequent uses, water will come out of the filter immediately. 

Let the filter run for four or five minutes to rinse the new cartridge and to drive as much air as possible from the filter. (Figure F.) New filters (and old filters with newly replaced cartridges) hold much trapped air. Until the air is expelled (which sometimes takes a couple of days), the filter will not operate normally. You can drink the water, although it may appear cloudy and water may continue to dribble from the spout after the unit is turned off.  Both conditions are the result of trapped air and will soon go away.

As water runs through the filter, the diverter valve remains opened. When the water is turned off, the valve will return automatically to closed position and you will have normal use of your sink. (Figure E.)

Do not run hot water through the unit. It is designed to process cold water only.

If neither of the adapters included with the unit will adapt the filter to your faucet, please call or email us for advice.
