Replacement instructions for H2O-F45:
Step 1: Turn off incoming water supply to the ltration unit.
Step 2: Open the cold water faucet handle to relieve the water
pressure.
Step 3: Remove lter from lid by turning it to the left, then pull
the lter down out of the lid. Discard the old lter.
Step 4: Remove plastic wrapping and cap from new lter.
Step 5: To install new lter cartridge, with the lter label facing
approximately 45 degrees to the left, push the lter into
the lid and twist it to the right until the lter locks in and
the label on lter is facing the front.
Step 6: Follow start-up procedure. Turn-on water supply at
cold water angle stop. Turn cold water faucet handle to
the open position to start the ow of water through the
unit. Run 5 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 7: Check for leaks. If you have any leaks, shut off the
water supply to your system, tighten any ttings then
turn the water 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
