1
Turn off the cold water shut-off valve to the
filter system and dispense water from
kitchen faucet until water flow stops
to relieve pressure.
3
For both new cartridges, line up arrow on
cartridge with unlocked position on head, insert
cartridge, and turn to locked position.
When looking at the system from the front the
US-2-R1 should be on the left and the US-2-R2
should be on the right.
Turn on drinking water faucet and and allow
water to run for 10 minutes to flush air and
carbon fines (very fine black powder).
2
Turn arrow on each cartridge from locked to
unlocked position.
Gently pull down to remove cartridge and discard.
NOTE: Place a pan or bucket under the filter
system to catch any water drips.
4
Remove and change battery (#1632) located in
the slot just below the Culligan logo on the faucet.
Once the battery is inserted correctly (positive
side facing out), the LED will blink red for about
30 seconds then it will shut off. To indicate the
filter needs to be changed soon it will flash yellow.
When the filter needs to be changed immediately,
it will flash red.
NOTE: The battery will need to be changed every
time a filter is changed (battery sold separately).
