Step 1 - Drill a Hole into the Sink for the Faucet
Notice:
There are several options which do not require drilling. Check to see if any of these
are feasible before proceeding to drill. If you do not require drilling for your
installation, proceed to step 2.
a) Spare hole:
If there is a spare hole in the sink covered by a chrome cover, simply remove
the chrome cover and install the RO faucet there.
b) Spray hose:
If the spray hose is not in use, remove the hose, and mount the RO faucet
there. Remember to plug up the outlet under the main faucet. If the spray hose uses a
diverter at the base of the spout, be sure to remove it to avoid trouble later on.
c) Hanging faucet:
If drilling a hole is not feasible (i.e. rental home, drill tool not available
etc.), the faucet can just hang on the cabinet door or wherever that is convenient. Be
creative!
Notice:
Manufacturer assumes no responsibility for damages resulting from installing faucets
into any surface. It is recommended to use a licensed contractor for this step.
For this, step, you will need:
Masking tape or duct tape
Variable speed drill with
⅛
” and 7/16” drill bits
½” hole saw bit for faucet opening – appropriate for the surface you are drilling
Determine the desired location for your RO Faucet
When drilling a hole for the RO faucet, choose a location that looks good, works well, and is most
convenient for dispensing pure water. An ample flat area is required for the faucet base so that the faucet
can be drawn down tightly.The 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.
