Installation, Operation and Maintenance Manual
9. Mount the Faucet (see Figure 6)
Installation With Faucet Air Gap Module:
A) Familiarize yourself with all components shown in the air gap faucet diagram (Figure 6).
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 fi rmly 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), fl at
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 fi nish.
10. Make Initial Faucet Tubing Connections (see Figure 1)
A) The orange 1/4” tubing should have already been connected to the Faucet Adapter with 1/4” brass
compression nut, insert and plastic sleeve.
B) Connect the 3/8” x 1/4” adapter that was used to fi ll 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 tub-
ing into fi tting. Refer to Figure 4 on page 17. If basement installation, route standard green 1/4” tubing
from an appropriate drain connection (e.g. laundry sink, fl oor drain, stand pipe) to intended location of
fi ltration 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 fi ttings 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 fi lter or plastic fi ttings.
• Mount fi lter 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.
