How to Change the Sediment and Charcoal Filters

Close both ball valves to the left and right of filter housings.

Push the little red button on the top of each filter housing to release the pressure. The housings cannot be removed until the pressure is released.

Use filter wrench provided to loosen and unscrew the housings. Replace the old filters with new ones. Hand-tighten housings.

Each time you replace the carbon filter, you'll want to rinse off residue from the new filter. To do this, once the filter is in place and the housing is screwed back on, turn on the ball valve to the left of the filters (the one that will allow water to run into the filters), but leave the ball valve on the right (the one prior to the UV light) shut. Open the hose bib and let the water run into a bucket until it runs clean (about a gallon). Close the hose bib and open the valve to the UV light.

Be sure not to toss out the O-rings that lie in the groove of the housings.
