Introduction System Maintenance Just because you can not taste it, does not mean that it is not there. Contaminants such as lead, chromium and arsenic (to name a few) are undetectable to the taste. Additionally, over time if you do not replace the filter element, other bad tastes and odors will be apparent in your drinking water. Thank you for your purchase of a state of the art Watts Pure Water Reverse Osmosis (RO) water treatment system.

STEP 5 STEP 7 Green Tube Connection Red 1⁄4" Tube Connection (from faucet) Step A – Locate green tube attached to the RO Module. Insert the open end of the green 1⁄4" tube into the open 1⁄4" Quick-Connect fitting on the AdaptA-Valve™ making sure the tube is pushed in all the way to the tube stop. Step A – Using the white plastic union found in the parts bag, determine where the 1⁄4" red tubing from the faucet and the 1⁄4" red tubing from the RO membrane housing would join together comfortably.

STEP 10 Startup Instructions Blue Tube Connection (to RO tank) Step A– Turn on the incoming cold water at the angle stop valve. Turn the knob on the Adapt-A-Valve™ by turning counterclockwise. Check the system for leaks, and tighten any fittings as necessary. (Check frequently over the next 24 hours to ensure no leaks are present). Step A– Position the RO storage tank in a desired location. You may stand it upright or lay it on its side (using the black plastic stand included).

6-Month System Maintenance Step E – Clean the filter housings (bowls) with a mild soap solution and rinse with water. Check O-rings and lubricate with water soluble lubricant. KY Jelly®, canola oil or other water based lubricants may be used. Petroleum based lubricants (such as Vaseline®) must not be used.

Membrane Replacement Removing the Membrane Order membrane by calling Watts at 1-800-224-1299 Item Needed: # 7100122, Includes: • (1) RO Membrane Step A – Use a 5⁄8" wrench to remove the Green Tube fitting on the left side of the horizontal membrane housing (end with one elbow). Step B – Remove the cap from the membrane housing by turning it counterclockwise to loosen. This reverse osmosis system contains a replaceable component (the RO membrane) which is critical to the efficiency of the system.

Troubleshooting PROBLEM 1. Low/Slow production CAUSE SOLUTION Low water pressure Assure a minimum of 40psi incoming water pressure. Watts sells a booster pump if home water pressure is low. Make sure water supply is turned on and Adapt-A-Valve™ is all the way open. Crimps in tubing Check tubing and straighten or replace as necessary. Clogged pre-filters Replace pre-filters. Fouled membrane Replace membrane and flow restrictor. 2.

Arsenic Facts Arsenic (As) is a naturally occurring contaminant found in many ground waters. Arsenic in water has no color, taste or odor. It must be measured by an arsenic test kit or lab test. Public water utilities must have their water tested for arsenic. You can obtain the results from your water utility contained with in your consumer confidence report. If you have your own well, you will need to have the water evaluated.
