1. Determine the desired location for your RO Faucet
The product water faucet may be installed on any flat surface at least 2” in diameter. Check the underside
of the location for interference. The standard faucet that is supplied with the system requires a ½” diameter
hole. The optional air-gap faucet requires a larger hole of ¾” to allow for the additional tubing connections
required.
Stainless Steel Sinks
Begin by placing a piece of masking tape or duct tape on the determined location where the hole is to be
drilled. Make a small indent to mark the desired drilling location using a center punch. Drill a pilot hole with
a
⅛
” metal drill bit. Enlarge the hole using a ¼” metal drill bit, using factory approved method or approved
plumbing practice.
Porcelain/Enamel Sinks or Tile Countertop
Sinks of this type are very easy to damage due to the nature of the materials of construction. A successful
installation into these sinks requires a knowledgeable technician with the proper cutting tools. We strongly
recommend the use of a “Relton” type device. Follow the directions that accompany the tool carefully.
2. Faucet Installation
Above the Countertop
1. Small Rubber Washer
2. Metal Faucet Hole Cover

Below the Countertop

5. Metal Lock Washer
6. Brass Nut
Installed in/on tubing:
7. Plastic Tubing Insert
8. Plastic Ferrule
(recommended)
9. Brass Ferrule
(included only
for those who prefer to use
brass instead of plastic)
10. Brass Compression Nut
Slide the small rubber washer, then the metal cover, then the large rubber faucet over the mounting
tube onto the faucet base, in that order so that the small rubber washer is on top.
Insert the mounting tube into the hole in the sink and position the faucet correctly.
From under the sink, install the plastic locating washer followed by the metal lock washer onto the
threaded mounting tube, and secure them with the brass nut. Screw on the brass nut and tighten.
Feed the brass compression nut onto the yellow tubing, threaded side facing the end, then feed the
plastic ferrule and install the tubing insert into the end of the tubing. Insert the end of the tubing into the
faucet mounting tube as far as it will go then tighten the nut with a wrench.
Note:
Only one ferrule is required. We recommend using the plastic ferrule. The brass ferrule is included only for those
who prefer to use brass instead of the plastic. The unused ferrule may be discarded.
Note:
Non-Air Gap Faucet – Comes with the system. (Air Gap may be purchased separately - part number
H-T5022.) Some states require the use of an air gap faucet. Check your local plumbing code to assure compliance.
