1.  Turn water supply off at saddle valve or at undersink cold water line, and remove protective 

shroud from bracket.

2.  Reset shut-off meter by pushing in knob and turning to the right (clockwise) until the arrow

on the top of the meter body is lined up to “Start”. (It is recommended that the cartridges
be replaced when the meter reads 625 gallons.  The shut-off meter will shut water pres-
sure to the faucet when 625 gallons are dispensed.) Open faucet to depressurize the
system.

3.  Lift red knob upward and hold.
4.  Turn cartridge to the left (counterclockwise) 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 

(clockwise) until a clicking sound is heard. The cartridge is now properly installed. Use
the 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.  Flush  5  gallons  through  system  (approximately  10  minutes).    Residual  air  may  cause

temporary cloudiness in water.  Place protective shroud back on bracket.

To reduce the risk associated with property damage due to water leakage:
 •  The disposable filter cartridge

must be replaced every six months or at the specified ser-

vice cycle.
