Filter Replacement Instructions
Replacement instructions:
Step 1: Place a towel under the lter
module to catch any excess water
that may drip out from the lters
during the changeover.
Step 2: To remove a lter cartridge:
Push and hold the button on the
valve head above the lter. Twist
lter counter-clockwise for about
45 degree while pulling downward
(from the head) Release button and
discard old lter.
Step 3: To install a lter cartridge:
Remove the seal cap and insert the
cartridge into the lter head, push
upward and twist the lter clock-
wise for about 45 degree until you
hear an audible “click” (the button
does not need to be pressed to
install new lters).
Step 4: Turn faucet handle to the
open position to start the ow
of water through the unit. Run 3
gallons of water through the unit in
order to ush out the normal black
carbon nes (it will “sputter” until
the air is purged out) from the unit.
A container with a known volume
can be lled to determine how
much water has ushed through
the system. Initially, the water
may appear cloudy which is due
to tiny air bubbles and it will clear
up shortly. Close the faucet when
nished.
Step 5: Check for leaks. If you have
any leaks, shut off the water supply
to your system, tighten any ttings /
housings then turn the water supply
back on. Check frequently over the
next 24 hours to ensure no leaks are
present. If you have any questions,
please call our retail customer
service at (888)321-0500.
