Installation Guide - A.O. Smith AOS-HERO-CHR Owner's Manual

STEP 1 Site Setup
Note: This system requires an existing faucet hole 7/8" to 1 1/2" in diameter in the sink
or countertop to install the supplied dedicated faucet. You may also replace an existing
kitchen sink sprayer, soap dispenser, or pre-existing hole on the sink or countertop.
If drilling a new hole, ensure faucet body will mount flat against surface and there is
sufficient tubing between faucet body and system manifold. If drilling, we strongly
recommend using a professional. Please wear safety glasses when drilling.
1. Unpack and unwrap box contents.
2. Turn off COLD water supply. Turn on the kitchen faucet to release pressure and
allow water to drain from the line.
3. Temporarily place system manifold and water tank into the under sink cabinet or
desired location to ensure adequate space and proper positioning.
Pre-installed 1/4" yellow tubing will be used to connect the dedicated faucet to
system manifold and water tank. Measure tubing from faucet hole to the back of
system manifold. Ensure the remaining tubing will be sufficient to connect system
manifold to tank. Do not cut tubing before following next instructions.
4. Remove system manifold and water tank from under your sink to begin installation.
