Cartridge Change Instructions (Refer to Corresponding Diagrams Below)
1. Turn water supply off at saddle valve or at undersink cold water line and remove protective shroud
from bracket.
2. Reset shutoff meter by pushing in knob and turning to the right until the arrow on the top of the
meter body is approximately lined up to 625 gallons. (The shutoff meter will shut water pressure to
the faucet down when the preset number of gallons are dispensed. It is recommended that the
cartridges be replaced at this time, or every twelve months.) Open faucet to depressurize the system.
3. Lift red knob upward and hold.
4. Turn cartridge to the left and gently pull straight down. Discard spent cartridge. If system has not
been properly depressurized, a small amount of water may discharge. Repeat for second cartridge.
5. Align tabs of the new cartridges with head and insert cartridge. Turn cartridge to the right until a
clicking sound is heard. Now the cartridge is properly seated. Use the color/number coded labels to
match “FILTER 1” cartridge with “FILTER 1” head. Repeat with Filter 2.
6. Turn on water at saddle valve or water line and check system for leaks. If leaks occur, check
connections or repeat cartridge installation.
7. Run faucet for five minutes to remove any air in the system. Residual air may cause temporary
cloudiness in water. Place protective shroud back on bracket.
