STEP 1: Turn off cold water shut-off valve to the filter system.
STEP 2: Turn cartridge counter-clockwise (see animation below) until unit releases. Gently pull down to remove from head. Discard used cartridge.
NOTE: Place a bucket or pan under the system to catch any water drips.
STEP 3: Hold new cartridge with label slightly facing to the left. The two nozzles on the top of the cartridge should be toward the back of the filter system, and the two extended flanges should be out to each side.
STEP 4: Lift cartridge straight up into the manifold until the two nozzles seat into the manifold ports, and the two extended flanges are flush with the manifold.
STEP 5: Turn cartridge clockwise (see animation below) until it stops.
STEP 6: Partially turn on the cold water shut-off valve to create a small trickle from the spigot.
STEP 7: Let it trickle for 2-3 minutes to let the carbon block get saturated. Check for leaks
STEP 8: Slowly turn on the cold water shut-off valve to get full flow.
STEP 9: Pressure test and purge per Step 7.
STEP 10: Repeat steps 1 through 8 for the second filter.
IMPORTANT NOTE: We highly recommend that you periodically check for leaks at least 48 hours after performing a filter change. Placing a baking sheet lined with some paper towels under the system for a few days allows you to quickly see if any problems develop. If a leak appears, please unscrew and then reattach your new filter(s) using the process described above. If the problem persists, please contact our Customer Service Department at 877-534-5837, extension 5.
After a filter change, it is normal for water to appear milky or cloudy. Additionally, some small participles (called "filter fines") may appear. These effects are NOT harmful to you, your family or the system. Your water will return to normal within a few days once the filters have fully purged all the air out of the system.
