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).  A non-switched 110V, 60Hz power source is 

required for the booster pump transformer.

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.

IMPORTANT NOTE:

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.

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

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 file, smooth out any rough edges.

To reduce the risk of eye injury while drilling countertop for 

faucet installations:

  • 

Safety glasses 

MUST

 be worn during the sink hole drilling 

operations.

CAUTION

  • 

The drinking water system faucet should be located on a flat 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.
