Notice
Do not use with water that is microbiologically unsafe or of unknown quality.
Filter housing must be protected against freezing temperatures, frost, snow, sleet, ice, high temperature, and direct sunlight.
Exposure to these elements can cause damage and product failures.
DO NOT install outdoors or in a wet environment. Moisture can cause the system electronics to malfunction.
• For cold water use only. Do not use on hot water line.
• Make certain that installation complies with all state and local laws and regulations.
• After periods of non-use (such as during a vacation) it is recommended that you let the water run for 5–6 minutes before using.
• Extended periods of nonuse (over six months) might require the replacement of the fi lter media for optimal performance.
• In case of equipment fault or other special situations, you can use the bypass valve to bypass the system. This will provide
your home with untreated water.
• For use with grounded power only.

Before Installation
1. Before installation, please check whether the valve head has come loose from the tank.
2. Open the upper cover by pulling up and then disconnecting the cable running to the electronic display.
3. Remove the three screws at the back of the unit and remove the rear cover.
4. Check the valve head for movement relative to the tank. If the valve head is loose, turn clockwise to tighten. Confi rm that the
O-ring is not pinched between the tank and valve head.
NOTE: This might require two people: one to hold the tank and another to turn the valve head.
NOTE: The gap between the tank and valve head should be smaller the 0.5mm.
5. Re-install the rear cover using only the two lower screws. The upper screw is only used for shipping and should be discarded.
NOTE: Do not re-install the top cover at this time.
Installation
1. Insert the drain fi tting into the drain tube and secure with the hose clamp.
2. Install the drain fi tting into the drain connection on the valve head and secure with clip.
