Installation Instructions 

Step 2 – Selecting the Faucet Location 

        NOTE:  The drinking water faucet should be positioned with function, convenience, and  
        appearance in mind. An adequate flat area is required to allow faucet base to rest securely.   
        The faucet fits through a 3/4-inch (19mm) hole.  Most sinks have pre-drilled 1-inch (35 or 38mm) 
        diameter holes that may be used for faucet. 

a)

 

Line bottom of sink with newspaper to prevent metal shavings, parts, or tools from 
falling down drain. 

b)

 

Place masking tape over the area to be drilled to prevent scratches if drill bit slips. 

IMPORTANT:

  To avoid damaging the sink, consult a qualified plumber or installer for drilling  

procedures in porcelain, granite, or stainless steel. 

c)

 

Mark hole with center punch.  Use a 1/4-inch (6mm) drill bit for a pilot hole, then, 
using a 3/4-inch (13mm) drill bit or hole saw, drill a hole completely through the sink.  
Smooth rough edges with a file. 
 

Step 3 – Mounting the Faucet 

a)

 

Remove wing nut (C) and metal washer (B) from the threaded shaft of the faucet. Leave  
the black rubber washer (A) on the threaded shaft. 

b)

 

Slide the threaded shaft of the faucet into drilled hole. 

c)

 

From under the sink, slide the metal washer on and thread on the wing nut.  
Tighten wing nut by hand until tight.  It may be necessary to have a second person 
hold the faucet while tightening the wing nut. 

d)

 

Install the faucet spout into the base by pushing firmly into hole in base then screw                                            fitting 
cover hand tight. 

 

 Caution:  Do not over-tighten the wing nut.  Hand tighten only.  Do not use pliers or wrench  

                 to tighten.  
 

Step 4 – Mounting the system 

a)

 

 Center system between water supply adapter and drinking water faucet. 
 NOTE:  Allow 1.5 inches (38mm) clearance below system to enable filter  
 cartridge changes.

 

 

 

NOTE: In the following step, leave enough space (approximately 1/2-inch (13mm)) 
between the head of the screw and the wall to easily slip system into place. 

 

b)

 

 Install mounting screws at least 15-inches (380mm) from cabinet floor and 
 9 1/4-inches (235mm) apart.  Place system over screws on wall and slide sideways.                                              
 Tighten screws. 

Caution:  Make certain system is firmly attached to wall to prevent possible damage from  
falling.

 

 

Step 5 – Connecting Tubing to the Faucet

  

Caution:  Do not over-tighten compression nut.  Use caution not to bend or crimp tubes when securing. 

a)

 

Locate compression nut in installation kit and faucet package. 

b)

 

Attach compression nut pieces (3) to one end of tubing. 
Caution

:  Tube must be fully inserted in the compression fitting base to the tube stop 

on the faucet stem.

 

c)

 

Attach tube with compression nut assembly to faucet stem by inserting tube into the faucet                                         
stem opening.  Gently push the tubing until it comes to a stop. 

NOTE:

 All nuts must be retightened when the system reaches projected operating temperature.
