INSTALLATION AND OPERATING INSTRUCTIONS NWS RESIDENTIAL WATER SOFTENERS MODELS: NWS100 NWS150 NWS200 NWS100M NWS150M NWS200M Installer, please leave with homeowner. Homeowner, retain for future reference.
SAFETY INFORMATION Read, understand, and follow all safety information contained in these instructions prior to installation and use of the NWS Series Water Softener. Retain these instructions for future reference. Failure to follow installation, operation and maintenance instructions may result in property damage and will void warranty. Intended use: The NWS Series Water Softener is intended for use in softening water in homes and has not been evaluated for other uses.
TABLE OF CONTENTS SECTION 1 2 3 4 5 6 7 8 DESCRIPTION BEFORE INSTALLATION INSTALLATION REGENERATION INSTRUCTIONS (Timing Setting Instructions) SERVICE INSTRUCTIONS SPECIFICATION AND OPERATING DATA PARTS MAINTENANCE LIMITED WARRANTY • Professional Installation Required: Installation requires shutting water off to home, cutting home water supply pipe and using a welding torch to add piping and fittings. Specialized tools and skills are required. Not a do-it-yourself type of project.
Check Your Pumping Rate and Water Pressure: Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage: 1) MINIMUM water pressure required at the water softener inlet is 20 psi (138 kPa). IF WATER PRESSURE IS OVER 80 psi (552 kPa), A PRESSURE REDUCING VALVE MUST BE INSTALLED IN THE WATER SUPPLY LINE AHEAD OF THE WATER SOFTENER. CAUTION To reduce the risk associated with property damage due to water leakage: • Do not install if water pressure exceeds 100 psi.
Facts to Remember While Planning Your Installation: 1) All installation procedures MUST conform to local and state plumbing codes. 2) If lawn sprinkling, a swimming pool, or geothermal heating/cooling or water for other devices/activities are to be treated by the water softener, a larger model MUST be selected to accommodate the higher flow rate plus the backwashing requirements of the water softener.
SECTION 2: INSTALLATION Proper installation sequence of water conditioning equipment is very important. Refer to the following diagram for your particular water supply. Figure 1 CAUTION To reduce the risk associated with property damage due to water leakage: • Read and follow Use instructions before installation and use of this water treatment system. • Installation and use MUST comply with existing state or local plumbing codes.

Step 5 Attach DRAIN LINE to DRAIN LINE FITTING. To prevent back pressure from reducing flow rate below minimum required for backwash, DRAIN LINE MUST be sized according to run length and relative height. Be careful not to bend flexible drain tubing sharply enough to cause "kinking" (if kinking occurs DRAIN LINE MUST BE REPLACED). Typical examples of proper DRAIN LINE diameters are: 1) 1/2 in. ID up to 15 ft. when discharge is lower than INLET. 2) 5/8 in. ID up to 15 ft.
SECTION 3: REGENERATION INSTRUCTIONS INSTRUCTIONS FOR USING REGENERATION FREQUENCY SCHEDULES: (Time Clock Initiated Models Only) 1) Determine ADJUSTED HARDNESS by adding three (3) times the iron content in parts per million (ppm) to the hardness in grains per gallon (gpg). The resulting number is ADJUSTED HARDNESS. EXAMPLE: Hardness is 14 gpg and iron is 2 ppm. ADJUSTED HARDNESS is 20 gpg (14 plus 3 times 2). 2) Select REGENERATION FREQUENCY SCHEDULE corresponding to your model.

HOW TO SET METER GENERATION CONTROL: TYPICAL RESIDENTIAL APPLICATION: To program, just set the time, set the hardness and it automatically monitors system needs and regenerates only when necessary. To set time of day, press red time set button and turn 24-hour gear until present time of day is opposite “time of day arrow.
SECTION 4: SERVICE INSTRUCTIONS Problem 1) 2) 3) Hard water, (unit NOT using salt; liquid level in brine tank NOT too high). Cause Solution A. Electrical service to unit interrupted. A. Assure permanent electrical service (check fuse, plug, pull chain or switch.) B. Timer not working. B. Replace timer motor. C. Timer improperly set. C. Increase frequency of regeneration and/or salt setting. D. Safety brine valve not opening. D. Replace safety brine valve. E. Salt “bridged” in brine tank.

SECTION 7: MAINTENANCE REPLENISHMENT OF SALT SUPPLY: The salt storage capacity of the brine tank is approximately 160 lbs. During each regeneration a specific amount of salt is consumed, thus requiring its periodic replenishment (the frequency is dependent on the regeneration schedule). Always replenish salt before the supply is exhausted to assure a continuous supply of softened water. TYPE OF SALT TO USE: Any type of water softener salt may be used.
