I. Installation Instructions
A. DETERMINE THE SYSTEM LOCATION
The system should be located under a sink. The exact placement
of the various components will vary from installation to installation.
You must decide where to install the faucet, tank and filtration
assembly by balancing convenience with ease of installation and
servicing. (See Fig. 1).
C. DETERMINE FAUCET MOUNTING LOCATION
If the sink already has a hole provided that can accommodate the
RO faucet, then no drilling is required. Additionally, a sprayer may be
disconnected to provide a suitable mounting hole for the RO faucet. A
pipe cap or plug will be required to seal the connection.
If drilling is required we strongly recommend you contact a
professional installer. The faucet should be positioned so that it empties
into the sink and the spout swivels freely for convenience.
Before drilling the hole, always check underneath the sink to ensure
that nothing will interfere with mounting the faucet such as reinforcing
ribs, support brackets or the cabinet construction.
If drilling a hole in your sink is required, the professional installer
should follow the instructions below.
D. MAKE THE FAUCET MOUNTING HOLE
CAUTION
To reduce the risk of eye injury while drilling countertop for

B. PREPARE THE AREA FOR INSTALLATION
Inspect the cold water supply line and determine if any special
fittings, in addition to what is included in the kit, are required.
It is a good idea at this time to check the condition of the undercounter
plumbing for any existing or potential leaks. Make sure to perform any
necessary repairs prior to the installation of the drinking water system.

IMPORTANT NOTES
•
The drinking water system faucet should be located on a fl at surface,
conveniently located near the sink, so that it empties into the sink.
Most sinks have pre-drilled holes designated for sprayers, soap
dispensers, and other accessories. If your sink does not have an
extra hole, we highly recommend professional installation.
•
Porcelain, enamel, and ceramic sinks require special procedures for
drilling holes. Professional installation is highly recommended.
Drilling 7/8" diameter hole through countertop or stainless steel sink:
1. Locate area to be drilled. Mark center of hole with center punch.
2. Drill hole with 7/8" drill bit suitable for countertop materials or cast
iron/stainless steel.
3. With grinding wheel or fi le, smooth out any rough edges.
