AIR GAP FAUCETS
1. Attach ¼” black
waste line from RO
to smaller ¼” barb
fitting under faucet.
2. Attach the 3/8”
waste line from drain
saddle to the larger
3/8” barb.
1. Faucet Installation
Drilling the Faucet Hole
The product water faucet may be installed on any flat surface at least 2” in diameter. Check the underside of the location for
interference
.
Drill a hole through the countertop where the faucet will be mounted at least 7/16" (11mm) in diameter. (Most
faucets will mount to a hole diameter of up to 1 ¼”) Drilling a ¼” (6mm) pilot hole first may be helpful. Take caution when
drilling the faucet-mounting hole. Different countertops may require special drill-bits and or installation methods.
Note: Some states require the use of an air gap faucet.
Check your local plumbing code to assure compliance.
Mounting the Faucet
Insert the faucet shank down through the drilled hole. Be sure the faucet body, faucet base, and the rubber faucet base washer
are in place above the sink as shown in Diagram A. Install the star lock-washer and nut, and then tighten firmly while faucet is
aligned in the desired location. Do not over tighten.
Tip: This step may be easier with 2 people. One person holds the faucet
in place from above, while the other tightens the faucet from underneath.
Note: To connect an additional point of use outlet (icemaker, extra faucet, etc.) place a tee-fitting connector along the line
between the faucet and the RO system. A line can then be run from the tee to the outlet device. Additional fittings and/or
connectors may be required. Icemakers may have proprietary connections and/or specific pressure requirements. Check with
your manufacturer for details.
2. Feed Water Assembly
Turn off cold water supply to the sink using the supply valve located under the sink. Different systems will come with
different adapters types and styles. Shown below are a few of the most common options. Only install to cold water supplies
and do not over tighten fittings.
Note: Some shut off valves have an extra port or a separate valve plumbed for an icemaker or filter system. In either of these
cases you will not need the feedwater adapter, just hook the feed line directly to this access point.
Scenario 1
Plastic Feed Water
Make sure the black washer is seated in the feedwater adapter. Tighten feedwater adapter to the valve with an adjustable
wrench. Tighten until snug but do not over tighten. Connect the tubing feed line (usually red in color) by plugging the tubing
end into the feed water connector collet, cut the tubing line anywhere along it, and install the inline ball valve, again by
pushing the tubing ends securely into the collets.
