Not to be reprinted in any form without writen permission. SECTION I: GENERAL INFORMATION Congratulations on your purchase of a Chem-Free™ Iron Removal System! The Chem-Free fiter removes dissolved, precipitated and bacterial iron from your water supply. Contrary to conventional methods, your Chem-Free filter requires NO chemicals (either added to the water supply or the filter). The unique process is patented and requires ONLY periodic backwashing for a few minutes to flush out entrapped iron that has accumulated in the filter tank. ‘When properly installed, the Chem-Free Iron Removal Sys: tem will provide many years of trouble-free service. Read this manual all the way through first, and then follow the installation steps in the proper sequence. DESCRIPTION AND OPERATION OF THE SYSTEM: ‘The Chem-Free filter consists of two major components which are’ 1) AHYDRO-CHARGER™, located between the well head and the pressure tank, adds a small amount of airto the iron-laden water whenever the well pump runs. 2) Abackwashing type fitter containing aspecial media that ‘causes the iron in the “Hydro-Charged’ water to precipi- tate throughout the fiter bed (rather than on the surface as in chemical oxidizing fiers.) This process produces aniron removal capacity of from 30,000 to 50,000 parts per milion (ppm) compared to 6,000 to 8,000 ppm for 4 chemical oxidation processes. The media DOES NOT require a chemical regenerant (such as potassium permanganate) for oxygen enrichment, salt, chlorine or any other chemicals. Your Chem-Free fiter automatically adjusts the pH to neutral or higher on acid water WITHOUT an acid neutralizer (a required piece of equipment with chemical oxidation fiters whenever the pH is less than 6.7). The ability to raise pH when itis below neutral (7 or less) greatly enhances the Chem-Free fite’s ability to remove iron efficiently, NOTE: Replenishment of the component of the filter media that adjusts pH, "MpH Adder™", may be required periodi- cally, the frequency of which is dependent on the raw water pH, the manganese (Mn) concentration in the water (it any) and the water consumption rate. Periodic backwashing of the filter bed flushes the precipi talediron to the drain and readies the filter for use again. The duration of the backwash procedure is approximately 30 minutes. The frequency of backwashing depends on iron concentration and water usage, and ranges from daily to once every 6 days. The volume of water consumed during the entire backwashing procedure is approximately 100 gallons (models NF 1000 and NF 1001).INSPECTING AND HANDLING YOUR 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 i set on sharp, uneven projections on the floor. Do not turn the filter unit’ upside down. MAKE SURE YOUR WATER HAS BEEN THOROUGHLY ‘TESTED: An analysis of your water should be made prior to the selection of your water conditioning equipment, Your Chem-Free dealer will generally perform this service for you, and may send a sample to the factory for analysis and recommendations. Enter your analysis below for a permanent record. NOTE: Hydrogen sulfide (H,S) 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 atter the sample is drawn. ANALYSIS OF YOUR WATER. Hardness pg Iron (Fe) ppm ‘Manganese (Mn) ppm pH Tannins (Humic Acid) ppm Hydrogen sulfide (H,S) ppm Other Other The following description of the water constituents listed above on the selection of the appropriate Chem-Free ‘model, and their effect on its operation will help to highiight their significance: IRON (Fe) lron concentrations as low as 0.3 ppm (0.1 ppm under ‘some conditions) will cause staining. The iron concentra- tion, together with the flow rate demand and the consump- tion rate of the water determines the basic size filter system. The higher these factors are, the larger the required system. The Chem-Free filter system is capable f filtering out the three main types of iron found in water supplies: Soluble iron (also known as “clear water” or ferrous iron), precipitated iron (also known as “red water” or ferric iron) and bacterial iron (also known as iron bacteria). There is no apparent upper limit of iron concen- tration for the Chem-Free filter, but special care must be taken when selecting a filter model if your water has a combination of high iron, very low pH and/or manganese levels above 0.2 ppm. SECTION 2: BEFORE INSTALLATION) The Chem-Free fiter is not bactericidal, Le. it does not remove or kil “bacterial iron’. It removes the iron upon which the bacteria may live or which it deposits in your plumbing fixtures, thus eliminating its effects. MANGANESE (Min) ‘The presence of manganese can be bothersome, even for a Chem-Free iron filter (and it is devastating for chemical oxidizing systems). As little as 0.05 ppm of manganese can produce a brownish or black stain. The ability of the Chem-Free filter to remove manganese depends on its concentration and the pH of the water. Although not specifically designed for the removal of manganese, the oxidation of manganese is very similar to that of iron. ‘ts oxidation is more pH dependent than that of iron, therefore, a pH of 8.2 or higher must be obtained. When this pH level is achieved, the precipitation of man- ganese may more readily occur. To accomplish this, ‘models are available where the media contains additional quantities of MpH Adder, the pH raising component (model designations with "M” suffix). In any application involving manganese, a larger model fiter is generally recommended (but only if the pumping rate is sutficient to backwash the larger size.) Ht, however, the manganese concentration is low (0.1 ppm of less) and the pH is 6.5 or higher, a Chem-Free filter containing standard Chem-Free filter media will generally perform satisfactorily, although backwashing should be performed at more frequent intervals. Under more severe conditions where the pH is very low andlor the manga- nese concentration is high, an acid neutralizer or chemical feed pump injecting soda ash installed ahead of the Chem-Free filter will maintain the required 8.2 pH level longer than the Chem-Free fier will between replenish- ment with MpH Adder pH ‘The pH of water measures its acidity. Water with a pH of less than 7.0 is acidic, above 7.0 itis alkaline, and a pH of 7.0 is neutral. The lower the pH value the greater the acidity, and the higher the pH value the more alkaline. Acidic water (pH less than 7.0) is corrosive to pipes, appliances, etc. A pH of 7.0 or higher facilitates iron removal - which is why the Chem-Free fier is designed to increase the pH when itis less than 7.0. The pH increasing component of Chem-Free media is ‘sacrificial’. that is, it slowly dissolves during the process or increasing pH. The rate this occurs is proportional to the degree of the pH increase and the water consumption rate (.2., the greater the pH increase and water consump- tion, the ‘greater the sacrificial rate). Thus, when the pH is increased to 8.2 or more, as is necessary when manga- nese is present, the sacrificial rate is even greater. Under the most severe conditions, the MpH component of the media may have to be replenished two to four times per year. On the other hand, if the raw water pH is 7.0 or above and no manganese is present, the sacrificial rate is very slight (see NOTE, Sec. 1)‘TANNINS (Humic Acid) Tannins (a humic acid), which may be present in some water supplies, are the result of various forms of decaying vegetation (the test for tannins can be performed by your dealer). Tannins can cause problems in the operation of the Chem-Free fitter by forming a sticky coating on the media, thus rendering it incapable of fitering the iron. Generally with tannin concentrations of 0.5 ppm or less, more frequent backwashing will prevent the sticky coating from forming. It does appear, however, that the level of tannin concentration affects the operation of the Chem- Free fiter differently in different geographical areas (in some areas the Chem-Free filter wll perform satisfactorily when tannin concentration is considerably greater than 0.5 ppm). tis therefore recommended that if the tannin concentration is 0.5 ppm or more, contact your dealer BEFORE installing the system. HYDROGEN SULAIDE (H,S) Hydrogen sulfide (often referred to as “sulfur’), is easily detectable by its objectionable “rotten egg” odor. Sulfur ccorrodes iron, brass, copper and silver. While the Chem- Free iron fiter is not intended to be used as a sulfur fitter, itis capable of removing sulfur in concentrations of up to 20r 3 ppm, and sometimes as high as 5 ppm. Whenever hydrogen sulfide is present, backwashing must be per- formed at more frequent ‘intervals, and the pumping system MUST include a standard air-to-water pressure tank with an air-relief valve. CHECK YOUR WATER PRESSURE AND PUMPING RATE: ‘Twowater system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage: 1) MINIMUM water pressure required at the filter tank inlet is 20 psi. IF PRESSURE IS OVER 100 PSI, A PRESSURE REDUCING VALVE MUST BE IN- ‘STALLED IN THE WATER SUPPLY LINE AHEAD OF THE HYDRO-CHARGER. NOTE: \f you have a municipal or a community water supply and daytime water pressure is 85 psi or more, nighttime pressure may exceed 100 psi. Call you local water department or plant operator to obtain pressure readings. If you have a private well, the gauge on the pressure tank will indicate the high and low system pressure. Record your water pressure data below: WATER PRESSURE Low psi High psi 2) The pumping rate of your well pump must be sufficient for satistactory operation of the HYDRO-CHARGER and to BACKWASH the filter. For models NF1001 and NF1001M the REQUIRED rate is 5 gpm (refer to SPECIFICATIONS AND OPERATING DATA for the backwash requirement for other models). To measure the pumping rate of your pump, follow these instruc- tions: 22 ‘a, Make certain no water is being drawn. Open spigot nearest pressure tank. When pump starts, close spigot and measure time (in seconds) to refill pres- sure tank (when pump shuts off). This figure represents CYCLE TIME. b. With the pressure tank full, draw water into a container of known volume, measure the number of gallons drawn until the pump starts again. This is DRAW-DOWN. Divide this figure by CYCLE TIME and multiply the result by 60 to arrive at the PUMP- ING RATE in gallons per minute (gpm). To aid in your calculation, insert the data in the following formula: DRAW-DOWN + CYCLE TIME__x ° (gals.) (secs.) = PUMPING RATE __ (gpm) EXAMPLE: CYCLE TIME is 65 secs.; DRAW- DOWN is 6 gals; then, PUMPING RATE equals: 6 gal. + 65 secs. x 60 = 5.5 gpm NOTE: The addition of tne HYDRO-CHARGER to the pumping system or plumbing and other water treatment devices (such as an acid neutralizer) may reduce the flow rate at the filter drain to an inad- equate level to properly backwash the filter. f you are uncertain whether your flow rate is adequate, contact your dealer BEFORE installing your Chem: Free filter, so that corrective action, it required, may be taken. LOCATE WATER CONDITIONING EQUIPMENT CAREFULLY: 1) Locate as close as possible to water supply source. 2) Locate as close as possible to a tloor or laundry tub drain. 3) Locate in correct relationship to other water condition ing equipment (see Figs. 1, 2 or 3 in Sec. 3). 4) Filters and softeners should be located in the supply line BEFORE the water heater. Temperatures above 100° F (38° C) damage filters and softeners and will void the factory warranty. Do NOT install a filter or softener in a location where freezing temperatures occur. Freezing may cause permanent damage to this type equipment and will also void the factory warranty. 5) 6) Allow sufficient space around the unit for easy servic- ing. 7) If your water source is a community water supply, a public water supply, OR you wish to bypass water Used for a geothermal heat pump, lawn sprinkling, out:buildings or other high demand applications, refer to Figs. 2 or 3 for additional equipment required. Also, reler to the SPECIAL INSTRUCTIONS following Step. 11 of Sec. 3, INSTALLATION. ‘THE IMPORTANCE OF YOUR PRESSURE TANK: The pressure tank found on private well systems becomes an integral part of the Chem-Free filter system by provid- ing necessary mixing and "residence time” to the "Hydro- Charged” water. While the Chem-Free iron filter system will perform satisfactorily with either a captive-air (blad- der’) type pressure tank or a standard air-lo-water type with an air volume control (air-relief valve), the bladder type requires more careful adjustment of the HYDRO- CHARGER to prevent gases from collecting in the pres- sure tank and the head area of the filter tank, A PROPERLY SIZED PRESSURE TANK OF EITHER STYLE WILL REQUIRE A MINIMUM PUMP CYCLE OF 60 SECONDS TO REFILL FROM THE WELL PUMP ON- TO-OFF PRESSURE SETTINGS. IF CYCLE TIME OF PUMP IS LESS THAN 60 SECONDS, PRESSURE TANK IS TOO SMALL CAUSING EXCESSIVE WEAR ON THE PUMP AND PROBABLE FAILURE OF THE FILTER SYSTEM. Under more severe operating conditions (low pH, high iron, manganese and small concentrations of sulfur), a standard air-to-water type pressure tank with an air-relief valve MUST be used (if bladder type tank is already in place - do not remove it - install the air-to-water pressure tank between the HYDRO-CHARGER and the bladder type tank) NOTE: \ your pressure tank (or any part of your water system) is not functioning properly, corrective action MUST be taken BEFORE installation of your Chem-Free Iron Filter. 23 FACTS TO REMEMBER WHILE PLANNING YOUR IN- STALLATION: 1) Allinstallation procedures MUST conform to local and state plumbing codes. 2) Allwater MUST pass through the HYDRO-CHARGER ASSEMBLY, pressure tank and the Chem-Free filter, OR refer to the special instructions for a splt-stream installation in Sec. 4. (System may maltunction if this instruction is ignored.) 3) If lawn sprinkling, a swimming pool, geothermal heat- ing/cooling or water for other devices/activities are to be treated by the Chem-Free filter, a larger model fter MUST be selected to accommodate the higher de- mands of these terms. ‘The pumping rate of the well pump must be sulficient to accommodate these iterns plus the backwashing requirement of the fiter. Con- sult your dealer for alternative instructions if the pump- ing rate is insufficient 4) Remember that the fter INLET is attached to the pipe that supplies water (i.e., runs to the pump), and the OUTLET is the line that runs toward the hot water heater Before commencing the installation itis advisable to study the existing piping system and to determine the size, number and type of fittings required. Typical system schematics shown in these instructions (Figs. 1, 2 or 8) will be of assistance 5) NOTE: \ the plumbing system is used as the ground leg of the electric supply, continuity should be main- tained by installing ground straps around any noncon- ductive plastic piping used in installation. 6) IMPORTANT: Aiways use tefion tape on threaded plastic fittings. NEVER use pipe dope, as it will deteriorate the plastic fitings.SECTION 3: INSTALLATION) PROPER INSTALLATION SEQUENCE OF WATER CONDITIONING EQUIPMENT IS VERY IMPORTANT.

(a) if MEDIA is already in the MEDIA TANK, proceed to Step 2. If MEDIA is shipped separately, add media thru filport adaptor using funnel (Figure 4). Fillport cap can be removed by removing quick release clip. NEVER ADD MEDIA ABOVE LINE INDI- CATED ON SIDE OF TANK. You may have received more media than required for the initial fill, ave extra media for future repienish ment (b) Reinstall filport cap. Make sure cap is fully inserted before reinstalling clip.

If heat is applied near HYDRO-CHARGER, remove rubber check valve to prevent damag. ing it. On badly scaled, older pumping sys- tems, it may be advantageous to install a “WYE" strainer to prevent plugging of HY- DRO-CHARGER nozzle with scale. WYE strainer must precede union on inlet side of HYDRO-CHARGER It existing water system includes a captive- air type pressure tank and it is desirable to install an additional air-to-water type with air release (NOT as a split-stream type installa- tion), install air-to-water tank between hydro- charger and existing captive-air tank. IMPORTANT: Betore proceeding, with HY- DRO-CHARGER installed, re-verily adequate pumping rate following the procedure de- scribed in Section 2. And after verification of adequate flow, depressurize system as de- scribed previously Cut main supply line as required to fit plumb- ing to INLET and OUTLET of BYPASS VALVE ASSEMBLY.

CERTAIN WATER FLOW ENTERS THROUGH INLET AND DISCHARGES THROUGH OUTLET. NOTE: \t installation is to be SPLIT- STREAMED prior to MEDIA TANK (Figure 2) or is a PUBLIC WATER SUPPLY type instal- lation (Figure 3) refer to special instructions following Step 11 ‘Attach ORAIN 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” (ifkinking occurs DRAIN LINE. MUST be replaced!) Typical examples of MINIMUM DRAIN LINE diameters are: 1) 1/2 in. 1D 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) 9/4 in. 1D when drain is 25 ft. away and/ or drain is installed overhead. Some areas prohibit the use of flexible drain 33 Step 7. Step 8. lines. Check with local code officials prior to installation. Position DRAIN LINE over drain and secure firmly. To prevent back-siphoning of sewer water, provide an air-gap of at least 2 in. or 2 pipe diameters between end of drain hose and drain (Figure 6). Do not raise DRAIN LINE more than 10 ft. above floor. SBE'SE Jn oo BE ow oT. FIGURE 6. DRAIN Make certain BYPASS VALVE INLET and OUTLET KNOBS are in "BYPASS" position. Turn on power to well pump or open main supply vaive completely. Manually stage con: trol to BACKWASH POSTION by turning “MANUAL REGERNERATION KNOB’, p. 5: 3, clockwise to "BACKWASH" position. Open BYPASS VALVE INLET KNOB approximately 1/4 of the way to full open (SERVICE POSI- TION) allowing the unit to fill slowly. This will purge any entrapped air in the bed. Once water is flowing to drain, open both the BYPASS VALVE INLET and OUTLET KNOBS: completely. (a) (b) Check for leaks. Leave unit in BACKWASH for at least 10 minutes or until drain line water runs clear, whichever is longer. This proce- dure will "reclassify" media that may have been disturbed during shipping and handling, Alter this preliminary backwash, stage CON- TROL VALVE to service position and plug timer into a 110/120V, 60 Hz non-switched power source. Manually initiate a complete “regeneration” process, allowing the unit to automatically proceed through a backwash and rapid rinse, see "HOW TO MANUALLY BACKWASH YOUR FILTER AT ANY TIME”, P53. Step 9. Set HYDRO-CHARGER by following these steps: (a) (o) (c) Open nearest faucet until pump starts, then close faucet. Place a finger lightly over SUCTION PORT (See Figure 7). A slight suction should be detected for approximately ONE-THIRD of Pumping cycle TIME (do not confuse with one-third of PRESSURE RANGE). |f suction duration is too short, increase by turning WATER FLOW ADJUSTING SCREW (Figure 7) CLOCKWISE. To decrease dura- tion, turn COUNTER-CLOCKWISE(6) Repeat Steps (a) through (c) until proper setting is obtained, NOTE: When the duration of the suction is too long, cold water may have a “milky” ap- pearance caused by excess air in the system. Correct this condition by reducing the duration of suction. This condition is commonly asso- ciated with bladder-type pressure tanks, In extreme cases where elimination of excess air prevents system from performing satisfacto- fly, it may be necessary to install a standard air-to-water type pressure tank with an air- relief vaive (See SECTION 2: THE IMPOR. TANCE OF YOUR PRESSURE TANK.) WATER FLOW ADJUSTING SCREW. WATER FLOW, WATER FLOW, im Z SUCTION PORT. FIGURE 7.

NOTE: Due to the nature of the Chem-Free media on start-up it sometimes requires 2 or 3 days for the Chem-Free fiter to completely remove the iron. Do not become alarmed if this occurs. During the initial backwashings, a small amount of fine white media may be ‘observed in drain water. This is normal and beneficial for the efficient operation of your filter system. SPECIAL INSTRUCTIONS FOR SPLIT-STREAM AND PUBLIC WATER SUPPLY TYPE INSTALLATIONS: For SPLIT-STREAM type installations, a secondary PRES. SURE TANK must be installed as in Figure 2. On PUBLIC. WATER SUPPLY type insiallations, a PRESSURE TANK must be installed as in Figure 3. It is recommended in both applications to use a standard air-to-water type pressure tank with a deep-well air volume control (air release valve). The pressure tank should be of same capacity as would normally be installed it water system were a standard private well type. Also note both applica tions require a NORMALLY-CLOSED SOLENOID VALVE. Follow standard installation procedures above with follow- ing additions and modifications. 34 1) Install PRESSURE TANK (SECONDARY PRESSURE TANK in Fig. 2) as indicated by appropriate diagram. 2)_ Install NORMALLY-CLOSED SOLENOID VALVE, 110/ 120V, 60Hz atter water meter and AFTER a line split for untreated water (if there is one) 3) On both types installation, install HYDRO-CHARGER. between PRESSURE TANK (SECONDARY PRES- SURE TANK on SPLIT-STREAM type installations) and NORMALLY-CLOSED SOLENOID VALVE. 4) Install PRESSURE SWITCH after HYDRO-CHARGER ‘and wire itto SOLENOID VALVE (SECONDARY PRES- ‘SURE SWITCH on SPLIT-STREAM). Set HIGH pres- sureon PRESSURE SWITCH (which controls opening and closing of SOLENOID VALVE) 2 to 3 psi LOWER, than LOW pressure on PRIMARY PRESSURE SWITCH. EXAMPLE: \i PRIMARY PRESSURE SWITCH is set at 40/60 psi, set SECONDARY PRESSURE SWITCH 20/38 psi. For PUBLIC WATER SUPPLY type installations, con- tact your local water department or plant operator and ask what the normal LOW system pressure is. Set HIGH pressure on PRESSURE SWITCH 2 to 3 psi LOWER than this figure. NOTE: Failure to set PRESSURE SWITCH as de- scribed above will NOT allow proper closing of SOLE- NOID VALVE during periods of low system pressure. Improper function of SOLENOID VALVE will cause total failure of system ‘SPECIAL SERVICE INSTRUCTIONS: Under normal circumstances removal of valve should never be required. However, if it must be removed, it can be done by disassembling the quick release clamp, by removing latch. Pressure should be relieved before attempting any disassembly. Upon reassembly, all o- rings should be lubricated with silicone grease. Reas- semble clamp as. shown in Figure 8. MAKE SURE ARROWS ON LATCH SIDE OF CLAMP ARE ALIGNED. i FIGURE 8.SECTION 4: PLUMBING SYSTEM CLEAN-UP| ‘THE FOLLOWING PROCEDURES ARE GUIDELINES ONLY BUT HAVE PROVEN SUCCESSFUL IN MOST INSTANCES, UNDER NO CIRCUMSTANCES SHOULD ANY PROCEDURE OUTLINED BELOW BE FOLLOWED IF CONTRARY TO THE APPLIANCE MANUFACTURERS INSTRUCTIONS. SHOULD THERE BE ANY QUESTIONS CONCERNING THE ADVISABIL- ITY OF PERFORMING A PROCEDURE, IT IS STRONGLY RECOMMENDED THE MANUFACTURERS AUTHORIZED SERVICE OUTLET BE CONSULTED PRIOR TO PERFORMING THE PROCEDURE. The plumbing system and water using appliances that have been exposed, even for a short time, to iron-fouled water need to be cleaned of the precipitated iron that has collected in them or iron “bleed” (staining) will continue to be a problem. Depending on the amount of iron in the water and the length of time the water system has been exposed to iron fouling, select from the following procedures those that apply to the type system and appliances that need cleaned to assure iron-free water at the points of use. ‘SOFTENER, It is not uncommon that the softener was installed in an effort to remove ferrous ("clear water’) iron from the water supply. Typically, a softener will remove some ferrous iron until the resin bed becomes fouled to the extent that it will lose both hardness removal capacity and the limited capacity for iron removal. This is the condition to expect the softener to be in when planning a system clean-up. Prior to closing main supply valve or turning power off to a private well system and preparatory to instaling the Chem-Free fiter system, do the following: 1) Disconnect brine draw line from brine cabinet and place the loose end into a five gallon plastic pail filed with a solution of hot water and 10 ozs. of resin mineral cleaner (IRON-X™) 2) Manually advance control timer to BRINE DRAW position (refer to instructions provided with your soft- ener), and allow all hot mineral cleaner solution to be drawn into mineral bed. Then IMMEDIATELY: 3) Close main water supply valve or turn power off to pump and proceed with fiter installation. During time Fequired to instal fiter system, iron-fouled softener resin will be chemically cleaned 4) Alter fiter installation is completed and final adjust- ments made with water turned on and brine tube reconnected, manually reposition timer on softener to BACKWASH position. Allow timer to perform an automatic, complete backwash and regeneration cycle, During backwashing of softener, all iron cleaned from the resin will be washed down drain. It is advisable atter chemically cleaning softener to regenerate sys tem twice to fully restore capacity lost due to iron fouling, 44 HOTWATERHEATER If the hot water heater has been exposed to both iron and hardness for a long period of time, replacement of the heater tank may be the only practical solution to prevent continued staining originating from this source. After completing the installation of the Chem-Free filter system, clean the hot water heater by following these instructions: 1) Shut off fuel supply to hot water heater and close heater inlet water valve. 2) Drain hot water tank completely. Open inlet water valve allowing heater tank to be refiled with iron-free water. Continue flushing until water runs clear to drain. 3) after approximately 30 minutes flushing, water does NOT clear, terminate flushing operation. Refll hot water heater with water and pour approximately 1/2 gallon of household bleach into top of heater tank Allow bleach solution to stand in tank for 20 to 30 minutes. Flush tank again until water is clear at drain. Turn fuel supply on. NOTE: |i water does not clear in approximately 10 minutes, water heater probably should be replaced. DISHWASHER Consult owner's handbook and follow manufacturers in- structions, TOILET FLUSH TANKS, Prior to commencing installation of the Chem-Free filter system, pour 4 to 6 ounces of resin mineral cleaner (IRON-X) or inhibited muriatic acid into flush tanks and bowls and let stand. When installation is completed, flush toilets several times with iron-free water. If iron deposits or stains remain, repeat procedure until clear.SECTION 5:_BACKWASHING INSTRUCTIONS] Periodic BACKWASHING of the Chem-Free filter bed is required to flush out the entrapped iron that has accumu- lated. This procedure is performed automatically at 1:00 a.m. for a period of approximately 30 minutes, and wil not interfere with a softener regeneration which is usually set for 2:00 am. ‘TOSET BACKWASH FREQUENCY FOR NORMAL HOUSE- HOLD APPLICATIONS: To determine and set BACKWASHING FREQUENCY, follow these instructions: 1) Select BACKWASHING FREQUENCY SCHEDULE corresponding to your model 2) Locate box intersected by number of persons in your family and iron concentration of water (if iron concen- tration is between two numbers in SCHEDULE, use higher number). 3) Number in box represents number of times per 6 days timer should be set. Refer to HOW TO SET TIME. CONTROL to set timer. EXAMPLE: You have model NF1001, 4 in family and 8 ppm iron. Refer to SCHEDULE for model NF1001 and locate box intersected by 4 in family and 8 ppm iron. ‘The figure “1” in box indicates a BACKWASH frequency of one time per 6 days (ita "2" or °3" were in box, frequencies of twice or three times per six days respectively would be indicated.) NOTE: The BACKWASHING FREQUENCY SCHED- ULES are based on average water consumption rates, and are merely guides. They are not intended to be Used if water used by outside spigots, a swimming pool, geothermal heat pump, or other high water usage devices or activities are to be treated by your, Chem-Free filter. If your application includes any of these, and you have already determined your model Chem-Free filter is capable of handling the flow rates involved, refer to the next paragraph for instructions on setting BACKWASH FREQUENCY. 54 ‘TO SET BACKWASH FREQUENCY COMMERCIAL MOD- ELS AND NON-STANDARD HOUSEHOLD APPLICATIONS: It your filter is to be used for a commercial application or for reasons covered above the BACKWASHING FRE- QUENCY SCHEDULE is not applicable, determine the backwashing frequency as follows: 1) Estimate DAILY IRON REMOVAL by multiplying iron concentration by estimated daily water consumption (use 60 gals. per person per day for normal household applications) Estimated Daily Water Usage x Iron Concentration was) ‘bem = Daily ron Removal (ppm) 2) Calculate BACKWASH FREQUENCY by inserting DAILY IRON REMOVAL trom above into the following formula (refer to specifications for IRON REMOVAL, CAPACITY of your model): Iron Removal Daily Capacity Of + tron Your Mode! Removal (pom) (ppm-gals) = Backwash Frequency (Gays) The resulting number of days between backwashings should be converted to the nearest MORE FRE- QUENT obtainable timer setting (.e., a calculated ftequency of 3.7 days should be converted to a 3 day interval, and a 9.2 frequency to a 6 day interval). Itis ‘not possible, however, to set the timer less frequently than once every 6 days. It your water contains high iron concentration, manga- nese, tannins or hydrogen sulfide it may be advisable to increase the backwash frequency up to daly, if necessary. It should be noted, however, that increas- ing the frequency or duration of backwashing WILL NOT overcome an insufficient pumping rate.BACKWASHING FREQUENCY SCHEDULES MODELS: NFO750, NFO751, NFO750M, NFO7SiM 3 jo 3 ole © Pi : e 3 o g ef 7 Baie gz | <|8 °| =| ala] z) = zie & ie z|e Bl eis Els | z\s als | 2 gles Zl= z “i i 3 5 5 - Slo gle? glele o |ole SK 2 5 3| 2 a] & 8 : ° =| |e z| |e © 2 als oI Z| 3 - < ° g = «| 2 «| o g a] [z e-Fe g : = o > * & o of & e | g ge) Bl al= ‘ 7 ae a = z a Bet 2 im g| {2 of = g ale w zt ae & 8 glee? &| |» of EB] fe -|- a a eee ae a als 2 gle 2 olesé Slalsect t} 0 2 gle & Sli*s e 3 gli 52MANUAL REGENERATION KNOB RED TIME-SET BUTTON TIME OF DAY ARROW HOW TO SET THE TIME OF DAY: (1) Press and hold the red button in to disengage the drive gear. (2) Tum the large gear untithe actual time ofday is opposite the time of day pointer (3) Release the red button to again engage the drive gear. HOW TO SET THE SKIPPER WHEEL: I you are setting the TIME CONTROL after MIDNIGHT but before NOON (i.e. A.M), the red pointer on the SKIPPER, WHEEL MUST be between two numbers as shown. If you are setting the TIME CONTROL after NOON but betore MIDNIGHT (i.e. P.M.) the red pointer MUST be COVERING one of the numbers. Setting the SKIPPER WHEEL in this manner will provide a 1:00 A.M. backwashing time. CAUTION: If directions above on HOW TO SET THE ‘SKIPPER WHEEL are not followed, BACKWASHING will not take place at the appropriate time of day. HOW TO SET DAYS ON WHICH FILTER IS TO BACK- WASH: Set the days that backwash is to occur by sliding tabs on the skipper weel outward to expose trip fingers, Each tab is one 53 ‘12 HOUR GEAR SKIPPER WHEEL (SHOWS EVERY DAY REGENERATION) RED POINTER, Extend or retract fingers to obtain the desired backwashing schedule. Typically, these units are backwashed every third day.; Consult your dealer for ‘specific recommendations for your water. HOW TO MANUALLY BACKWASH YOUR FILTER AT ANY TIME, ay. ‘Tum the manual backwash knob clockwise until the knob engages the program wheal. This slight movement of the knob will start the backwash program, ‘The backwash knob will make one revolution in approxi- mately 1 1/2 hours and stop in the position shown in the drawing. Even though it takes 1 1/2 hours for the knob to complete one revolution, the backwash cycle of your unit is approximately 30 minutes in duration. NOTE: Should it become necessary to change the TIME-OF-DAY which backwash is to start, the time on 12 HOUR GEAR must be altered. For example, if 2:00 ‘a.m. regeneration time is desired instead of 1:00 a.m., set the 12 HOUR GEAR one hour earlier than actual time.SECTION 6: TROUBLESHOOTING) A.

LISTED ABOVE, CONSEQUENTLY, THE FOLLOWING STEPS SHOULD READ AS FOLLOWS: Ti Step 1 (a) (b) (c) (a) (e) (f) (9) SECTION 71 & 3P972) If MEDIA is already in MEDIA TANK, proceed to Step 2. If MEDIA is shipped separately, remove CONTROL VALVE by disassembling quick release CLAMP (see Fig. 8, P.3-4 - 3P976 & 5P235, P.3-1 - 3P971 & 3P972). Remove center DISTRIBUTOR tube and pour GRAVEL out of MEDIA TANK into a bucket. Place DISTRIBUTOR back into MEDIA TANK making sure it rests on the bottom center of TANK. Lubricate inside of bell end of CENTERING TOOL, provided, with silicone grease and place over end of DISTRIBUTOR. Add GRAVEL removed in (b), back to MEDIA TANK while holding down on CENTERING TOOL. Add MEDIA to MEDIA TANK while holding down on CENTERING TOOL and holding DISTRIBUTOR in center of TANK. NEVER ADD MEDIA ABOVE LINE INDICATED ON SIDE OF TANK. You may have received more MEDIA than required for the initial fill, save extra MEDIA for future replenishments. Reattach CONTROL VALVE making sure DISTRIBUTOR goes into tube adaptor protruding from bottom of VALVE.NT & NF START-UP BACKWASHING INSTRUCTIONS FOR PRE-WASHED CATALYST MEDIA Ongoing product testing Indicates the Catalyst Media can support higher backwash rates without danger of loss of media, therefore the drain line flow control button is now being omitted from all Catalyst Filters. Chem-Free Filters still have drain line flow control buttons. Failure to perform following procedure may result in loss of media upon Initial backwash: 1) Install unit per installation instructions. 2) With unit bypass valve in *bypass" position, manually index control valve to "backwash" postion. (Refer to instruction manual.) 3) Open bypass valve approximately 1/2 open. This will allow unit to fill slowly from the bottom up, thus eliminating air entrapment which can occur if unit is filled with water from the top. 4) Once a steady flow of water is going to drain, completely open bypass valve to "service" position. 5) Allow unit to continue to "backwash" to drain for approximately 15 minutes. Advance control valve to "rapid rinse" position to compact the bed for service. 6) You may wish to manually initiate an automatic regeneration and allow unit to cycle through the steps of "backwash" and “rapid rinse" to verify proper operation of system and further clean the bed. 7) During this initial regeneration you should observe the flow to drain to make sure well and well pump are capable of maintaining a steady flow rate. Ifthe pump or well recovery is not adequate, i.e., system pressure continuously decreases, the fiter will not properly clean Itself of fitered material and will eventually fail. NOTE: When installing a Catalyst Filter do not install drain line overhead or use flexible vinyl tubing, either will result in failure of the system. :‘eBid BEG owen Auedwiog ey Mold Jequinn Jequiny lees 1ePoW “eo1yJ0 sno Bunoeluoo uayM elqeteAe oq Pinoys e1ojo104) Pue YOU UE Jo GOUENSs} e10}9q peysenbed 2 IM Jequinu [EYES BULL “e}EId4OEq AAIEA OU 10 J8AOD @AIEA JO.]UOD OU JOUYO 0} PareUpe S1 eyeId BIE EY “(Mojeq eunBy 898) Jequinu jepow yun ey) 0} xeU eyeId BIEP oY) UO peyeoo| JqWiNU jeUEs YUN BUY epnjou!

Use of any lubricant, other than a silicone paste (not spray) material, as manufactured by Dow Coming, will damage the control valve body, intemal parts and timer gears and will void warranty. Spray lubricants, such as WD40, or silicone sprays which may contain petroleum components, and other lubricants like Vasoline, Crisco and most oils will soften and deteriorate any plastic parts they may contact. 2. Media lodged in control valve due to improper start-up upon installation, after adding replenishment media’ or rebedding is not covered under warranty. Media can be flushed into the valve when air passes through the bed while the filter is being backwashed. PROPER START-UP: ‘A.
