Switch the dark gray backwash dial to
position 1 and wait 30 seconds. Then turn it to
position 2, wait 30 seconds, and continue to
do so until reaching position 0.
ROTATE GRAY BACKWASH DIAL TO EACH POSITION FOR 30
SECONDS

Regular backwashing ushes out contaminants from the lter cartridges and
helps to maintain ow rate.

NOTE: Once you begin the backwash process, water will stop ow-
ing from the tap. This is normal. During dierent rotations, water
will ow out of the backwash hose. Once the dial is returned to
position 0, water will resume owing from the tap.
WARNING: Never consume water from the backwash outlet. It is
not safe to drink.
