Step 1
Step 3
Let system sit for one minute after the tank is
empty to let the system depressurize before
attempting to remove filter housings.
Items needed:
√ Stage 1 - Sediment Filter
√ Stage 2 - Carbon Block Filter
Turn off the incoming water supply to the RO.
Open the RO Faucet and allow water to drain
from the tank until it is completely empty.
Step 2
Water may be saved in a container for drinking or to rinse
system parts.
For more leverage you may leave the RO
module attached to wall of cabinet. If you
are unable to access the module while it is
mounted, remove it prior to changing filters.
Starting with the closest housing (Stage 1),
remove it by turning it clockwise (left), empty
water, then discard filter. Continue on to the
2
nd
housing (Stage 2).
Step 4
Clean the filter housings (bowls) with a mild
soap solution and rinse with water. Check
O-rings and lubricate with water soluble
lubricant.
KY Jelly® or other water based
lubricants may be used. Petroleum based
lubricants (such as Vaseline®) must not be
used.
Step 5
Insert a new sediment filter (cloth like ap-
pearance) into the 1st filter housing which is
the one on the water inlet side (white tubing
from the adapt-a-valve) of the RO system and
re-install housing.
Step 6
Insert the new Carbon Block filter (White end
caps & plastic netting) into the second filter
bowl and re-install housing.
Step 7
Step 8
Turn water supply “on” to the RO unit.
Open the RO faucet and leave it open until
water begins to trickle out (it will come out
slowly).
Step 10
Step 9
Close the RO faucet allowing the storage
tank to fill with water. It may take 4 to 6
hours to fill the tank completely depending
on the production capability of the mem-
brane, local water temperature and water
pressure.

NOTICE
6 Month System Maintenance
Before re-installing the filter bowls back on to the
system, check O-rings to make sure they are still
in place. *
