Place a tray under the system to catch any water that spills during removal of the filter housings. 2. Open faucet to release pressure. 3. Unscrew bottom of filter housings from caps. Use the filter wrench. Discard used cartridges. I like to do this one at a time to minimize the chance of mixing up the filters. 4. Remove black rubber O-rings from grooves in housings. Wipe grooves and O-rings clean; set O-rings aside. 5. Wash out housings and rinse thoroughly. 6. Lubricate each O-ring with a coating of clean silicone grease. With two fingers, press each O-ring securely into groove below the threads of the appropriate housing. CAUTION: The rubber O-ring provides the water-tight seal between the cap and the bottom of the housing. It is important that the O-ring be properly seated in the groove below the threads of the housing or a water leak could occur. 7. Insert cartridges in the bottom of the housings. Make sure cartridge slips over standpipe in the bottom of the housing. 8. Screw bottoms of housings back onto caps securely; do not over-tighten. 4th Stage Post-Filter Cartridge: post-filter should be replaced every twelve months. 1.
