WARNING
To reduce the risk associated with the ingestion of contaminants due to use with water that is microbiologically unsafe or of
unknown quality:

• Do not use water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
• To reduce the risk associated with hazardous voltage
• If the electrical system requires the use of the cold water system as an electrical safety ground, a jumper must be used to ensure a sufficient ground connection across the softener installation piping — refer installation to qualified personnel.
• Do not use the softener if the wall-mounted power supply is damaged — contact qualified service personnel for repair.
• To reduce the risk associated with back strain
• Follow safe lifting procedures.

CAUTION
To reduce the risk associated with property damage due to water leakage:

• Read and follow Use Instructions before installation and use of this system;
• Installation must comply with existing state or local plumbing codes;
• Protect from freezing. Drain system when temperatures drop below 40°F (4.4°C);
• 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;
• When water supply is shut off, shut off fuel or electric power to water heater;
• Do not use torches or other heat sources near plastic plumbing, as damage may occur;
• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur;
• On plastic fi ttings, use thread-sealing tape only. Never use pipe sealant or pipe dope on plastic fittings, as damage may occur;
• Do not bend spring on fl oat assembly or damage to the vent may result;
• Do not install this system in direct sunlight or outdoors without protection from precipitation.
• To reduce the risk associated with property damage due to plugged water lines:
• Pay particular attention to correct orientation of control valve. Water flow should match arrow on control valve.
• The Inlet and Outlet of other water treatment equipment products will vary depending on the control valve brand used.

IMPORTANT NOTES
Failure to follow instructions may result in leakage and will void warranty.

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

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 specifi c 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 fl ushed out with a garden hose when dirt and other insolubles ac-cumulate. The clean-out frequency depends on the type salt used and the regeneration frequency. The clean-out should be done when the salt level is low. Steps to follow:

1. Disconnect brine line at either end.
2. Turn brine tank upside down and discard old salt. Remove salt grid plate.
3. Rinse out with a garden hose.
4. Reconnect brine line.
5. 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
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 fi xtures. 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.

CHECK WATER PRESSURE AND PUMPING RATE
Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage: The MINIMUM water pressure required at the softener tank inlet is 20 psi. IF PRESSURE IS OVER 100 PSI, 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 (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 100 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 BACKWASHING 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.  Locate as close as possible to water supply source.
2. Locate as close as possible to a floor or other adequate drain.
3. Locate in correct relationship to other water conditioning equipment (Figure 1).
4. Temperatures above 150° F (66° C) will damage the softener and void the factory warranty.
5. Do NOT install the softener in a location where freezing temperatures occur. Freezing may cause permanent damage and will also void the factory warranty.
6. Allow suffi cient space around the unit for easy servicing.
7. Provide a non-switched 110V, 60Hz power source for the control. (Reference transformer to verify proper power supply voltage.)

CAUTION
To reduce the risk associated with property damage due to water leakage:

• Installation must comply with existing state or local plumbing codes.
• 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.
• Do not use torches or other heat sources near plastic plumbing, as damage may occur.
• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur.
• On plastic fi ttings, use thread sealing tape only. Never use pipe sealant or pipe dope on plastic fi ttings, as damage may occur.
• To reduce the risk associated with property damage due to plugged water lines:
• Pay particular attention to correct orientation of control valve. Water fl ow should match arrow on control valve. The Inlet and
• Outlet of other water treatment equipment products will vary depending on the control valve brand used.
• Remember that the fi lter INLET is attached to the pipe that supplies water (i.e. runs to the pump) and OUTLET is the line that runs toward the water heater or other water treatment equipment device.
• Before commencing the installation, it is advisable to study the existing piping system and to determine the size, number and type of fittings required. Typical system schematics shown in Figure 1 will be of assistance.

SECTION 2: INSTALLATION

CAUTION
To reduce the risk associated with property damage due to water leakage:

• When water supply is shut off, shut off fuel or electric power to water heater;
• Do not use torches or other heat sources near plastic plumbing, as damage may occur;
• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur;
• On plastic fi ttings, use thread-sealing tape only. Never use pipe sealant or pipe dope on plastic fittings, as damage may occur;
• To reduce the risk associated with property damage due to plugged water lines:
• Pay particular attention to correct orientation of control valve. Water fl ow should match arrow on the control valve. The Inlet and
• Outlet of other water treatment equipment products will vary depending on the control valve brand used.

Step 1
If not factory pre-installed, attach BYPASS VALVE using ADAPTER COUPLINGS, CLIPS and SCREWS to CONTROL VALVE (Figure 2).

Step 2
Verify all packing materials have been removed from the brine tank.

Step 3
Shut off water at supply valve. On a private well system, turn off power to pump and drain pressure tank. Make certain pressure is relieved from complete system by opening nearest faucet to drain system. SHUT OFF FUEL SUPPLY TO WATER HEATER.

Step 4
Cut main supply line as required to fi t plumbing to INLET and OUTLET of unit.

Step 5
Attach plumbing. DO NOT apply heat to any fi tting connected to BYPASS or CONTROL VALVE as damage may result to internal parts or connecting adapters. Make certain water fl ow enters through inlet and discharges through outlet.

NOTE: When ordering components, always specify model number.

Step 6
Attach DRAIN LINE to DRAIN LINE FITTING. To prevent back pressure from reducing flow rate below the minimum required for backwash, DRAIN LINE MUST be sized according to run length and relative height. Be careful not to bend fl exible 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 fi rmly. To prevent back siphoning of waste water, 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
Connect one end of the 3/8 in. poly line to BRINE VALVE located on the right side of CONTROL VALVE. Connect other end to ELBOW inside of BRINE WELL. Brass insert sleeves and plastic ferrules must be used where necessary. (Figure 2 and CONTROL VALVE PARTS Drawing, Section 6).

Step 9
Install OVERFLOW LINE to brine tank OVERFLOW FITTING (Figure 2). Discharge of line must be lower than OVERFLOW FITTING. DO NOT INTERCONNECT THE OVERFLOW LINE WITH VALVE DRAIN LINE.

Step 10
Make certain BYPASS VALVE IS IN the “BYPASS” position. After all plumbing connections have been completed, open main water shut-off valve or restore power to well pump. Check for leaks and correct as necessary.

Step 11
Manually stage control to BACKWASH POSITION by turning the “MANUAL REGENERATION KNOB”, clockwise to the “BACKWASH” position, refer to HOW TO SET TIME CLOCK REGENERATION CONTROL (Section 3).

Step 12
Partially open (approximately 1/4 of the way) the INLET valve in plumbing or BYPASS VALVE (Figure 4). This will allow the unit to fi ll slowly from the bottom up, eliminating air entrapment. Allow unit to fi ll 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 the transformer into a non-switched 110V, 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 frequency, 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 conditions exist, such as high concentrations of iron or hardness and/or high fl ow rates or daily water consumption.

This adjustment is easily performed by loosening the screw holding the white cam (on the backside of timer) and adjusting the pointer to the desired refi ll time. Refi ll rate is controlled by a fl ow control to 0.5 gpm. By adjusting the amount of time the unit is allowed to refi ll 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 refi ll time should be set to 4 minutes. 4 minutes x 0.5 gpm = 2 gals. 2 gals. x 3 lbs/gal = 6 lbs.

Maximum operating temperature 150° F (66° 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. Actual capacity may vary substantially depending on water analysis and operating conditions.
2. For satisfactory performance indicated fl ow rates and duration should not be exceeded. Flow rates specifi ed are adequate for normal applications.
3. For system to operate properly, pumping rate of well pump ( if applicable) MUST be sufficient to backwash unit at rate specified.

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 11:00 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 fi ll 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). Installation is now complete, and the water softener is now ready for service!

SECTION 3: REGENERATION INSTRUCTIONS

INSTRUCTIONS FOR USING REGENERATION FREQUENCY SCHEDULES

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 the REGENERATION FREQUENCY SCHEDULE corresponding to the model. Locate box intersected by DAILY WATER USE and ADJUSTED HARDNESS (if ADJUSTED HARDNESS is between two numbers in the schedule, use a higher number). The number in box represents FREQUENCY or NUMBER OF times per 12 DAYS timer should be set to regenerate. Refer to HOW TO SET TIME
   CLOCK REGENERATION CONTROL to set the correct frequency.

3. 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 the appropriate REGENERATION FREQUENCY SCHEDULE and locate box intersected by 450 gpd and 5 gpg adjusted hardness. Figure “3” in box indicates a REGENERATION frequency of THREE TIMES PER 12 DAYS (if a “1”, “2”, “4”, 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.

MODEL: HWS050

MODEL: HWS100

HOW TO SET TIME CLOCK REGENERATION CONTROL

HOW TO SET DAYS ON WHICH WATER SOFTENER IS TO REGENERATE
Rotate the skipper wheel until the number “1” is at the red pointer. Set the days that regeneration is to occur by sliding tabs on the skipper wheel outward to expose trip fingers. Each tab is one day. The finger at red pointer is tonight. Moving clockwise from the red pointer, extend or retract your fingers to obtain the desired regeneration schedule.

HOW TO SET THE TIME OF DAY

1. Press and hold the red button in to disengage the drive gear.
2. Turn the large gear until the actual time of day is opposite the time of day pointer.
3. Release the red button to again engage the drive gear.
4. The time of regeneration is preset for 2:00 a.m.

HOW TO MANUALLY REGENERATE THE WATER SOFTENER AT ANY TIME.
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 at 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.
