ACTIVATE BATTERY
Figure 4
Remove cover from lter and pull the plastic tab from the
battery to activate lter timer.
For the rst 72 hours, the faucet diverter valve may drip intermittently, until the lters become fully saturated. Once they are
saturated, you should anticipate a residual ow of water each time you use the lter as the system is vented and designed to
clear the line. Due to the vented design, it is normal for the lter to drip when the regular faucet is in use.
Notice
FLUSH FILTER
Figure 5
Turn the diverter valve up and ush lter with cold water
for 10 minutes.
MAINTENANCE
When should I replace the lter cartridges?
You will see a blinking green LED light on the front of the system. After 5.5 months, the LED will blink amber letting you know
your lters are almost expired. After 6 months the LED will blink red indicating it is time to change the lters.
