- Note: The installation instructions below are for your reference only. An air gap faucet is not included with this system.
- Drill a hole in the kitchen sink or countertop if there isn't already a spare one. Refer to the manual of the faucet when determining the size.
- Place the front plate and the rubber washer on the base of the faucet. Mount the faucet on the countertop.
- From under the sink, connect the RO system pure water output line to the faucet stem. Attach the black drain line from the RO system to the drain input barb. Attach one end of the faucet drain line to the drain output barb and the other end to the dra...

Step 7. a. See figure Sample Installation and figures of system top view and note connection
points A-B, C-D, E-F, and G-H.
Step 7. b. Facing the system's front, 1
st
stage is the see-through housing located on the right-
hand side. Connect the RED tubing Feed Water Adapter (AFW43) (point A) to the stage 1
elbow fitting (point B).
Step 7. c. Connect the Flow Restrictor (point C, 3" long cylinder with a FLOW labeled on it)
to the Drain Saddle (point D) with the BLACK tubing.
Step 7. d. On the right side of the Post Carbon Filter (FT15, 5
th
stage), connect the T-fitting
(point E) and the Tank Valve (point F) with the YELLOW tubing.
Step 7. e. At the left end of stage 5 FT15 filter, insert the BLUE tubing (links to RO faucet)
into the elbow fitting.
* Models with UV/AK/DI: RO water flows out of point G at FT15 and flows into the next
stage's input (left) side. So the BLUE tubing should be connected to the output side of the
final stage.
Step 7. f. Connect the other end of the BLUE tubing to the RO faucet (refer to How to Use
the Quick-connect Fittings).
Step 7. g. You may neatly organize the tubing, but make sure to leave enough length so the
filter system can be moved freely in and out of the cabinet when replacing filters.
Step 7. h. You can mount the system using two 10 x 1-1/4 Phillips Flat
Wood Screws. This will make replacing filter cartridges easier. Note: If
you plan on mounting/hanging the system, it is highly recommended to
include supports under each of the bottom three housings. Supports under the housings will
take the water weight off the housing threads and ensure the thread strength does not decay
over the years.
Step 8: System Start-up (model specific sub-steps are marked with a *)
Note: You may now plug in the booster pump to an outlet. The pump will not turn on until the
water is flowing.
* If your model has a UV stage, do not plug in the UV power until the system has been fully
flushed.
Step 8. a. Make sure no tubings are kinked. Turn the Tank Shut-off Valve OFF
(perpendicular to the yellow tube). Place a towel under the system to catch any possible
water leaks.
Step 8. b. To prevent any residual carbon from the carbon pre-filters from getting into the RO
membrane, you previously left the tubing to the inlet of the RO membrane housing cap
