Before installing:
• Do not install this filter where the line pressure may exceed 100 psi.
The operating pressure range for this filter is between 20 psi – 100 psi.
• Install on cold water lines only (40° – 90°F). Protect unit from freezing.
• Installation of the filtration system must comply with existing state and local
plumbing codes. A. O. Smith and its manufacturer is not liable for consequential
or incidental damages due to improper installation.
• Do not install the unit on its side. It must be installed upright to maximize contact
with media bed.
• Improper sequence of equipment will affect performance and could possibly
damage your system.
Note: It’s imperative that this system is flushed properly prior to final
installation. The granular carbon medium used in the bottom tank contains
1-2% by volume of carbon fines that must be flushed out prior to use. Surge
flushing is the best method for purging these carbon fines from the media bed.
INSTALLATION GUIDE

STEP 1
Pre-Condition the Unit by Surge Flushing
1. Remove red shipping caps from the inlet
and outlet ports on the main housing.
2. Using supplied adapter, connect a garden
hose to the inlet port so the water will flow
into the system and out of the outlet port.
3. Slowly turn faucet on and allow discolored
water to flow from outlet into a suitable
drainage area. The first few gallons will
appear black and cloudy due to carbon fines.
4. After an initial 15-minute flushing, begin
a period of “surge flushing” by turning
water supply on for 30 seconds and
then off for 30 seconds, repeating cycle
for 15 minutes or until initial surge of
water is completely clear and free from
discoloration and cloudiness.
5. Disconnect the system from the garden
hose and position it for final installation.
Note: Do not drink flushed water.
