9. Mount the Faucet (see Figure 5)
Installation With Faucet Air Gap Module:
A) Familiarize yourself with all components shown in the air gap faucet diagram (Figure 5).
B) Slide stainless base plate and rubber washer up tube and brass threaded stem of faucet.
C) Connect length of standard green 1/4” tubing to smaller barb on air gap faucet. Push on firmly until it seats.
D) Connect length of black 3/8” tubing to larger barb on air gap faucet.
E) Feed both the green and black tubing and threaded nipple through sink/counter mounting hole and
orient the faucet.
F) From below sink/counter, assemble the white spacer (open end up, open side toward air gap), flat
washer and hex nut on threaded nipple and tighten by hand.
G) Back off on hex nut just enough to slide slotted washer between white spacer and underside of sink/
counter (with open side of slotted washer closest to air gap tubes.)
H) After rechecking faucet orientation, tighten hex nut (9/16” wrench) until faucet feels secure.
I) From above the sink, make any minor orientation corrections by turning the faucet with a padded ad-
justable wrench. NOTE: Flats on chrome faucet may be used for tightening with an adjustable wrench.
Use care not to mark chrome finish.
10. Make Initial Faucet Tubing Connections (see Figure 1)
A) The orange 1/4” tubing should have already been connected to the feedwater valve with 1/4” brass
compression nut, insert and plastic sleeve.
B) Connect the 3/8” x 1/4” adapter that was used to fill tank to the 1/4” blue faucet tube.
C) Route black 3/8” tubing from faucet air gap module to drain saddle so that it slopes continuously
downward without loops or low spots. Cut to proper length and connect to drain elbow by pushing
tubing into fitting. Refer to Figure 6. If basement installation, route standard green 1/4” tubing from an
appropriate drain connection (e.g. laundry sink, floor drain, stand pipe) to intended location of filtration
assembly. An air gap must be installed between outlet and drain connection.

• The Uniform Plumbing Code dictates that there must be an air gap between the RO reject line and the waste
drain. The faucet air gap module connections can be eliminated only if an air gap is provided elsewhere in the
drain line (i.e. basement installations).
IMPORTANT NOTES
To reduce the risk associated with property damage due to water leakage:
•
Ensure all tubing and fittings are secure and free of leaks.
• Installation and Use
MUST comply with all state and local plumbing codes.
•
Do not install if water pressure exceeds 125 psi (862 kPa). If your water pressure exceeds 125 psi, you
must install a pressure limiting valve. Contact a plumbing professional if you are uncertain how to check
your water pressure.
•
Do not use a torch or other high temperature sources near filter or plastic fittings.
• Mount filter in such a position as to prevent it from being struck by other items used in the area of installation
(waste baskets, etc).
• Shut off inlet water supply and depressurize system as shown in manual when changing cartridges or servicing.
CAUTION
11. Install the Purification Assembly and Storage Tank
Undercounter Installation:
The RO assembly is usually mounted to the right or left sink cabinet sidewall, taking into consideration the
space available and the tank location. Generally, the tank is placed in the rear of the sink cabinet while the
purification assembly is positioned toward the front for better accessibility.
To mount the RO assembly, elevate it at least 2” off the cabinet floor (with cartridges installed) and, while
keeping level, mark the location of the mounting holes on the cabinet sidewall. Make small pilot holes with
an awl or drill and screw in the two mounting screws, leaving just enough protruding to allow bracket mount-
ing slots to slide over them.
NOTE: If the cabinet sidewalls are not of solid construction, the RO assembly can be set on the cabinet
floor and held against the sidewall with the mounting screws. However, the RO assembly will then need to
be lifted from the mounting screws in order to remove filter cartridges.
The tank can be oriented either vertically or horizontally. It is generally placed to the rear of the cabinet but
can be set in the from center (between the sink basins) for ease of access if space permits.
Basement Installation:
The RO assembly is generally mounted to the basement wall (using wall anchors) or to wood ceiling sup-
ports. To mount the RO assembly, keep bracket level and mark the location of the mounting holes. Install
wall anchors and/or mounting screws as required. Leave screw heads protruding to allow bracket mounting
slots to slide over them.
The tank may be oriented either vertically or horizontally and can be placed on a shelf, on the floor, or sus-
pended from the ceiling supports using sturdy brackets.
An effort should be made to minimize the distance between the tank and RO assembly to help assure an
adequate flow rate to the faucet.
12. Make Final Tubing Connections (see Figure 1)
With all of the components in place, the final tubing connections can be made. When routing tubing be-
tween components, several guidelines should be observed.
Tubing runs should generally follow the contour of the cabinets rather than interfere with the cabinet stor-
age area. Strive for neatness and an orderly tubing “flow” using fasteners (e.g. insulated staples) to secure
the tubing. Arrange the tubing so there are no sharp bends and leave some “play” in the tubing for ease of
servicing, then cut tubing to desired length.
Try to keep the tubing form the RO assembly to the tank and faucet as short as practical for good flow.
Undersink Installation:
A) Connect orange 1/4” tubing from feedwater valve to “Feed” connection on RO assembly.
B) Connect one end of blue 3/8” tubing to faucet adapter and the other end to the “faucet” connection on
the RO assembly.
C) Connect yellow 3/8” tubing from storage tank to the tee on the RO assembly.
D) Route special red “SFC” tube from RO assembly module (factory made connection) toward faucet. Do
not cut this special SFC tube. Its length is important to maintain proper efficiency and performance.
E) Remove white plug from coupling fitting on end of red SFC tube. Connect SFC tube to one end of 1/4”
x 1/4” coupling fitting.
F) Connect the green 1/4” tubing from faucet air gap to 1/4” coupling fitting on the end of SFC tube
(See Figure 5).

To reduce the risk associated with a hazardous voltage due to an installer drilling through existing electric
wiring or water pipes in the area of installation:
•
Do not install near electric wiring or piping which may be in the path of a drilling tool when selecting the position
to mount the filter bracket.
