Read the entire manual to familiarize yourself with the  
system and determine the best location for installation. 
Check and comply with all local plumbing codes.

1.  Prior to installation, turn off the cold water shut-off 

valve under the sink.

2. 

Temporarily place system tank into the sink cabinet 
(or desired location) to ensure adequate space and 
proper positioning.

3.  Wait to cut tubing and follow instructions below. 

Measure out ⅜” white tubing from the top of the tank 
to the outlet side of the system manifold and mark ⅜” 
tubing. Then measure remaining length of ⅜” tubing 
from the manifold to the desired location of the faucet 
hole to ensure there will be enough ⅜” tubing available 
for both connections. Remove system and tank from 
under your sink to begin installation.
