How to install an Air-gap Faucet (optional)
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 drain saddle on the drain pipe.
Assemble the hardware according to the faucet manual.
Step 3: Installing the Drain Saddle
Step 3. a. Choose a spot on the drainpipe that is convenient for installing the drain saddle and
tubing. A horizontal pipe is recommended to minimize the dripping sound.
Step 3. b. Drill a 1/4" hole in the drainpipe, and paste the black sticky pad around the hole.
Step 3. c. Cut the BLACK tubing end to make a 45-degree angle. Slip the plastic nut and front
plate on the tubing. Insert the tubing into the 1/4" hole in the drainpipe, install the back
plate, and tighten the two screws with hex nuts while the tubing remains in the hole.
Step 3. d. Tighten the nut on the Drain Saddle by hand. Pull the tubing lightly to make sure it
is secure.
Install the Air Gap (optional)
Note: If your sink does not have an unused hole for mounting the air gap body, bore a hole
depending on the size of the air gap body next to the sink using an electric drill and hole saw.
• Remove the cover and collar from the top of the air
gap body. Leave the gasket, washer, and nut threaded
to the bottom of the air gap body.
• Attach the drain hose from the dishwasher to the leg.
Secure with a stainless steel hose clamp.
• Attach the drain hose to the leg from the garbage
disposal or side inlet piece of the sink trap. Secure
with a stainless steel hose clamp.
• Push the air gap body up through the unused hole of
the sink rim or countertop. Approximately 2-1/4" of
the air gap body should appear above the sink rim or
countertop.
• Securely tighten the nut and collar against the sink rim
or countertop. Place the cover over the air gap body.
