3.1: Regarding Filter Capacity
3. Maintenance
1. exact filter capacity varies in proportion to the amount of water used and the level of impurities in the water being
processed. For contaminants reduced through physiochemical adsorption, the filter capacity is 750 gallons. For
contaminants reduced through mechanical filtration, capacity claims are inapplicable due to broad variations in the
quality and quantity of physical matter in the drinking water. excessive physical matter will cause the DWS to clog,
diminishing flow rate but reducing the contaminants from the resultant water stream.
2. For optimum performance and to maintain the lifetime warranty on your system housing, it is essential that the filter be
replaced when the first of the following occurs: a. annually, b. when the system reaches its rated capacity, c. when the
flow rate diminishes, or d. when the filter becomes saturated with bad tastes and/or odors.
3.2: Removing the Old Filter
3.3: Installing the New Filter
1. Before opening the DWS housing, place the system either on a folded
towel, in a basin or other container, or in the sink.
2. With the faucet off, press the right button on the diverter valve to select the
filtered water spout and flush water out of the DWS.
3. When the flow of water stops, press the left button on the diverter valve to
stop the filtered water spout.
4. With the system sitting upright, slide the hand tool over the top so that the
ridges on the tool fit into the grooves on the housing top.
5. Holding the base steady, use the hand tool to turn the DWS counter-
clockwise to loosen.
6. Once the top is loose, you can complete rotating it counter-clockwise by
hand.
7. Once unscrewed, lift the housing top off of the base, leaving the black
gasket on the bottom of the base.
8. Remove the old filter cartridge from the base by pulling it upward and
slightly twisting until it is released from the base.
9. Dispose of the old filter in your waste container.
10. Rinse out the inside of the system housing, hand washing if necessary.
1. If you have not done so already, remove the plastic wrapper and instruction
wrap from around the new filter.
2. Insert the new filter in the center port of the housing base, twisting slightly.
Push straight down on the filter to ensure that it is firmly in place.
3. Place the housing top over the filter and back onto the base. Turn it
clockwise to tighten.
4. If necessary, use the hand tool to further tighten the housing top to the
base, turning it clockwise while holding the base steady.
5. Proceed to 1.5: Preparing Your Drinking Water System to complete the
installation.
