SIGNATURE 2 SERIES
Installation Requirements
• A level floor position ahead of piping into water heater.
• Unit must be installed at least 10’ ahead of the inlet to a water heater to prevent damage due to
back-up of hot water.
• DO NOT install the unit in an area of direct sunlight or where freezing temperatures may occur!
(See Installation Diagrams for proper placement and plumbing connections.)

(See Installation Diagrams for proper placement and plumbing connections.)
Nitrate Filter Location / Other Requirements
• Locate the unit near an unswitched, 120 volt / 60 Hz grounded electrical outlet.
• Check for distance and proper drain installation (e.g. floor drain, washing machine standpipe).
• Determine type and size of piping required for nitrate filter connection (e.g. copper, galvanized, PVC plastic).
Note: If household plumbing is galvanized and you intend to make the installation with copper (or vice versa), obtain
di-electric unions to prevent dissimilar metal corrosion.
Note: Where the drain line is elevated above the control valve or exceeds 20 feet in length to reach the drain, use 3/4”
I.D. drain line tubing instead of 1/2” I.D. Drain line tubing is not included.
Caution: If sweat soldering copper pipe (remember to always use lead free solder and flux), cover yoke and bypass valve
with wet rags to prevent heat damage to connections and control valve! If using PVC or plastic pipe, primers and
solvent cements specifically recommended for use with potable water are required.
Note: All plumbing lines not requiring “soft” water should be connected “upstream” of the softener.
(See Typical Installation Diagrams)
Installation Procedure
Water Supply Connections and Bypass Valve
To allow for filter servicing, swimming pool filling or lawn sprinkling, a manual bypass valve has been installed at the factory.
The bypass allows water to be manually routed around the filter.
1. Position filter at desired location for installation. (See Installation Diagram.)
2. Turn OFF main water supply and OPEN nearest faucet to relieve pressure.
3. Cut main line and install appropriate elbows and extensions. Inlet and outlet connections on the control valve are
3/4” FNPT.
Note: An optional 1” FNPT is available.
Caution: Raised arrows located on the sides of control valve body and bypass valve indicate proper direction of water
flow. Install inlet and outlet piping in direction of arrows.
4. Rotate handle on bypass valve to the bypass position
5. Turn the main supply line on to restore water service to the home.
6. OPEN nearest faucet to evacuate air and repressurize plumbing lines.
7. Check for leaks!
