PLAN FOR INSTALLATION
Prior to installation, we recommend you read the entire manual to familiarize yourself with the
system, and help you determine the best location for installation. Please check and comply with
all local plumbing codes.
PREPARE SITE FOR INSTALLATION
NOTE: If you have metal drain pipes, consult a plumber for installation of drain connection.
1. Prior to installation, close the cold water shut-o valve.
2. Temporarily place system manifold, remineralizer, and
tank into the under sink cabinet or desired location
to ensure adequate space and proper positioning.
3. ⁄" white tubing will be used to connect manifold to tank, and from faucet stem to
remineralizer. Measure out ⁄" white tubing from the top of the tank to the outlet side of the
system manifold and mark ⁄" tubing. Then measure remaining length of ⁄" tubing from the
remineralizer to the desired location of the faucet hole to ensure there will be enough ⁄"
tubing available for both connections. Wait to cut tubing and follow instructions below.
4. Remove system, remineralizer, and tank from under your sink to begin installation.
