****** Page 3 ****** TABLE OF CONTENTS SECTION 1 2 3 4 5 6 7 DESCRIPTION BEFORE INSTALLATION INSTALLATION REGENERATION INSTRUCTIONS (Timer Setting Instructions) SERVICE INSTRUCTIONS SPECIFICATIONS AND OPERATING DATA PARTS MAINTENANCE SECTION 7: MAINTENANCE REPLENISHMENT OF SALT SUPPLY: The salt storage capacity of the brine tank is approximately 280 lbs. (127 kg). 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. There are advantages and disadvantages to every type of salt. Please ask the local dealer for his advice. The unit is designed to compensate for the disadvantages. BRINE TANK CLEAN-OUT: To prevent service problems the brine tank should be emptied and flushed out with a garden hose when dirt and other insolubles ac- cumulate. The clean-out frequency depends on the type salt used and regeneration frequency. The clean-out should be done when the salt level is low. Steps to follow: SECTION 1: BEFORE INSTALLATION Before starting the installation we suggest reading this manual all the way through for an overview, and then follow the installation steps in the proper sequence. IMPROPER INSTALLATION could void the warranty. Installation should be completed by a qualified plumber. INSPECTING AND HANDLING THE WATER SOFTENER: Inspect the equipment for shipping damage. If damaged, notify the transportation company and request a damage inspection. Handle the equipment with care. Damage can result if dropped or if the brine tank is set on sharp, uneven projections on the floor. When handling, do not turn the water softener unit upside down. MAKE SURE YOUR WATER HAS BEEN THOROUGHLY TESTED: An analysis of the water should be made prior to the selection of water conditioning equipment. The dealer will generally perform this service, and may send a sample to the factory for analysis and recommendations. Enter the analysis below for a permanent record. IMPORTANT NOTES Hydrogen sulfide (H2S) must be tested for at the well site. For accuracy, the sample must be drawn with the pump RUNNING, and the test be completed within ONE minute after the sample is drawn. Softeners are designed to remove hardness but can handle reasonable amounts of soluble iron if consideration is given to content when selecting model and regeneration settings. To treat sulfur (hydrogen sulfide), bacterial iron, precipitated iron or very high levels of soluble iron requires special equipment in addition to a water softener. For best results, a Chem-Free Iron Reduction Filter is recommended for use on waters containing more than 2 ppm of iron. Analysis Of Your Water 1) 2) 3) 4) 5) Disconnect brine line at either end. Turn brine tank upside down and discard old salt. Remove salt grid plate. Rinse out with a garden hose. Reconnect brine line. Add enough water to brine tank to cover the air check in the brine well 1″ before adding new salt. Perform approximately once a year if rock salt is used; with other types of salt, approximately once every other year. PREVENTING IRON-FOULING OF MINERAL BED: CONTAMINANT Hardness Iron (Fe) Manganese (Mn) pH Tannins (Humic Acid) Hydrogen Sulfide (H2S) Other Other 1-1 YOUR WATER —gpg ppm ppm ppm ppm ppm ppm If iron is present in the water supply, the softener mineral bed will eventually become iron-fouled, resulting in reduced softening capac- ity and rust-stained fixtures. Mixing one to two ounces of IRON-X Mineral Cleaner with every 80 lbs. of salt added to brine tank will minimize these problems from occurring. IRON-X is available from the dealer. PERIODICALLY CHECK TIME OF DAY SETTING: Power outages will cause TIME OF DAY timer setting to become incorrect. To reset, refer to appropriate HOW TO SET TIME CLOCK REGENERATION CONTROL, Section 3. MALFUNCTION OF UNIT: The water softener, under normal conditions, should provide years of trouble-free service; however, since it is a mechanical device, it can malfunction. (Refer to Section 4, SERVICE INSTRUCTIONS, if necessary). CHANGE OF OPERATING CONDITIONS: Should the daily water usage, or water quality change, the regeneration program settings may have to be adjusted. Consult the dealer if any of the above occur. 7-1

****** Page 4 ****** CHECK WATER PRESSURE AND PUMPING RATE: Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage: ONLY THOSE PARTS CIRCLED IN DRAWING AND/OR LISTED BELOW ARE STOCK ITEMS ALL OTHERS ARE SPECIAL ORDER, NON-RETURNABLE l) 2) MINIMUM water pressure required at the softener tank inlet is 20 psi. IF PRESSURE IS OVER I OO PSI, A PRESSURE REDUC- ING 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 (689 kPa). If the system water pressure exceeds 100 psi, the installation must use a pressure limiting valve. Contact a licensed plumbing professional if you are uncertain how to check your water pressure. • Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum prevention. IMPORTANT NOTE If the source is a municipal or a community water supply and daytime water pressure is 85 psi or more, nighttime pressure may exceed 1 00 psi. Call the local water department or plant operator to obtain pressure readings. If the source is a private well, the gauge on the pressure tank will indicate the high and low system pressure. Record water pressure data below: WATER PRESSURE Low psi High psi If the source of water is a private well, the pumping rate of the well pump must be sufficient for satisfactory operation and BACK- WASHING of the WATER SOFTENER. (See SPECIFICATIONS AND OPERATING DATA, Section 5). LOCATE WATER CONDITIONING EQUIPMENT CORRECTLY: Select the location of the water softener with care. Various conditions which contribute to proper location are as follows: 1) 2) 3) 4) 5) 6) 7) Locate as close as possible to water supply source. Locate as close as possible to a floor or other adequate drain. Locate in correct relationship to other water conditioning equipment (Figure 1 Temperatures above 1 500 F (660 C) will damage the softener and void the factory warranty. Do NOT install the softener in a location where freezing temperatures OCCUL Freezing may cause permanent damage and will also void the factory warranty. Allow sufficient space around the unit for easy servicing. Provide a non-switched 1 1 OV, 60Hz power source for the control. (Reference transformer to verify proper power supply voltage.) 1-2 REF.

****** Page 7 ****** step 6 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. when discharge is slightly higher than INLET. (3) 3/4 in. ID when drain is 25 ft. away and/or drain is installed overhead. step 7 Position DRAIN LINE over drain and secure firmly. To prevent backsiphoning of waste wa- ter, provide an air gap of at least 2 in. or 2 pipe diameters between end of drain hose and drain (Figure 3). DO NOT raise DRAIN LINE more than 10 ft. above floor. step 8 EQUIPMENT DRAIN LINE DRAIN SECTION 5 : SPECIFICATIONS AND OPERATING DATA AIR GAP 2″ REF. Figure 3.

This will allow the unit to fill slowly from the bottom up, eliminating air entrapment. Allow unit to fill slowly, failure to do so could result in loss of resin to the drain. Once a steady stream of water, no air, is flowing to drain, the INLET OR BYPASS VALVE can be fully opened. Manually advance control to SERVICE POSITION. Plug transformer into a non-switched 1 1 OV, 60Hz power source. (Reference transformer to verify proper power supply voltage.) step 13 Set REGENERATION FREQUENCY. Refer to REGENERATION FREQUENCY SCHEDULES (Section 3) to determine correct fre- quency, then refer to HOW TO SET TIME CLOCK REGENERATION CONTROL (Section 3) for instructions on setting frequency. IMPORTANT NOTE Regeneration settings are factory preset for the most efficient salt use and minimum water consumption used for regeneration (as little as 50 gallons). REGENERATION FREQUENCY SCHEDULES are designed for use with factory regeneration settings (listed in SPECIFICATIONS AND OPERATING DATA, Section 5). The control valve design permits adjustment of the salt dosage. This adjustment may be necessary when unusual operating condi- tions exist, such as high concentrations of iron or hardness and/or high flow rates or daily water consumption. This adjustment is easily performed by loosening the screw holding the white cam (on backside of timer) and adjusting the pointer to the desired refill time. Refill rate is controlled by a flow control to 0.5 gpm. By adjusting the amount of time the unit is allowed to refill the brine tank, the salt dosage can be adjusted. Each gallon of fresh water added to the brine tank will dissolve 3 lbs. of salt. EXAMPLE: If a salt dosage of 6 lbs. is desired, the salt refill time should be set to 4 minutes. 4 minutes x 0.5 gpm = 2 gals. 2 gals. x 3 lbs/gal = 6 lbs. 2-2 Maximum operating temperature 1500 F (660 C); Electrical requirements 110V/60Hz (220V/50Hz); Operating pressure 20-100 psi (138 – 689 kPa). All types water softener salt may be used (See MAINTENANCE). Specifications subject to change without notice. NOTES: 1) 2) 3) Actual capacity may vary substantially depending on water analysis and operating conditions. For satisfactory performance indicated flow rates and duration should not be exceeded. Flow rates specified are adequate for normal applications. For system to operate properly, pumping rate of well pump ( if applicable) MUST be sufficient to backwash unit at rate specified. 5-1

****** Page 8 ****** step 14 Set TIME OF DAY (refer to appropriate HOW TO SET TIME CLOCK REGENERATION CONTROL, Section 3). When shifting to daylight saving time (and back), you may wish to adjust TIME OF DAY accordingly. IMPORTANT NOTE TIME OF REGENERATION is pre-set for 2:00 a.m. because at this time water consumption is generally minimal (a built-in hard water bypass does, however, permit water to be drawn during regeneration). Should the application require regular use of water during the 2:00 to 3:00 a.m. regeneration period, or if other water treatment equipment is also set for 2:00 a.m. regeneration, the TIME OF REGENERATION will need changing. To change, adjust time of day on 24-HOUR GEAR ahead or behind actual time of day. For example, if 1•.00 a.m. regeneration is desired and actual time of day is 10:00 a.m., advance 24-HOUR GEAR one hour to 1 1 a.m.; or, should 3:00 a.m. regeneration be desired, set gear back one hour to 9:00 a.m. step 15 Before loading salt, using a pail or garden hose, add enough water to brine tank to cover the air check in the brine well by approx. one (1) inch. Then add initial salt fill to brine tank, and one cup full of unscented laundry bleach to brine well. step 16 RESTORE FUEL SUPPLY OR POWER TO WATER HEATER. Put softener through complete regeneration to sanitize the system before use (Refer to HOW TO SET TIME CLOCK REGENERATION CONTROL for instructions on manual regeneration).

RED TIME-SET BUTTON MANUAL REGENERATION KNOB ERVICE 24 HOUR GEAR RED POINTER SKIPPER WHEEL (SHOWS EVERY DAY REGENERATION) EXAMPLE: Rounding is always down. You have Model HWS050 (13,000 grain capacity at factory salt setting), 450 gpd usage and 5 gpg adjusted hardness. Refer to appropriate REGENERATION FREQUENCY SCHEDULE and locate box intersected by 450 gpd and 5 gpg adjusted hardness. The figure “3” in box indicates a REGENERATION frequency of THREE TIMES PER 12 DAYS (if a “l l’, etc. were in box, frequencies of once, twice and four times per twelve days, respectively, would be indicated.) This can be calculated as 13,000/(5 x 450) = 5.8 days between regeneration, rounding down to every 4 days or 3 times in a 12 day cycle, as indicated.

Set the days that regeneration is to occur by sliding tabs on the skip- per wheel outward to expose trip fingers. Each tab is one day. Finger at red pointer is tonight. Moving clockwise from the red pointer, extend or retract fingers to obtain the desired regeneration schedule. 1) 2) 3) 4) HOW TO SET THE TIME OF DAY: Press and hold the red button in to disengage the drive gear. Turn the large gear until the actual time of day is opposite the time of day pointer. Release the red button to again engage the drive gear. Time of regeneration is preset for 2:00 a.m. HOW TO MANUALLY REGENERATE THE WATER SOFTENER AT ANYTIME. 12 12 NR NR NR NR Not Recommended Turn the manual regeneration knob clockwise. A slight, clockwise movement of the manual regeneration knob engages the program wheel and starts the regeneration program. The black center knob will make one revolution in the following approximately three hours and stop in the position shown in the drawing (SERVICE POSITION). Even though it takes three hours for this center knob to complete one revolution, the regeneration cycle of the unit might be set only one-third of this time. In any event, conditioned water may be drawn after rinse water stops flowing from the water softener drain line. 3-2
