IMPORTANT NOTES

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.

• Protect from freezing, relieve pressure and drain system when temperatures are expected to drop below 33°F (0.6°C).

• Do not install on hot water supply lines. The maximum operating water temperature of this ﬁ lter system is 110°F (43.3°C).

• Do not install systems in areas where ambient temperatures may go above 110°F (43.3°C) or below 40°F (4.4°C).

• Do not install if water pressure exceeds 100 psi. If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve. Contact a plumbing professional if you are uncertain how to check your water pressure.

• Do not install where water hammer conditions may occur. If water hammer conditions exist you must install a water hammer arrester. Contact a plumbing professional if you are uncertain how to check for this condition.

• Where a backﬂ ow prevention device is installed on a water system, a device for controlling pressure due to thermal expansion must be installed.

• Do not use a torch or other high temperature sources near ﬁ lter system, cartridges, plastic ﬁ ttings or plastic plumbing.

• On plastic ﬁ ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic.

• Take care when using pliers or pipe wrenches to tighten plastic ﬁ ttings, as damage may occur if over tightening occurs.

• Do not install in direct sunlight or outdoors.

• Mount system in such a position as to prevent it from being struck by other items used in the area of installation.

• Ensure all tubing and ﬁ ttings are secure and free of leaks.

• SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after water is shut off.

• Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum prevention.

• Do not apply heat to any ﬁ tting connected to Bypass or Control Valve as damage may result to internal parts or connecting adapters.

• Install on a ﬂ at/level surface. It is also advisable to sweep the ﬂ oor to eliminate objects that could pierce the brine tank.

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.

IMPORTANT NOTES

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

• Since some media dissolves as it elevates pH level, it will increase the hardness. If your dwelling is equipped with a tankless water heater, the installation of a water softener may be necessary to prevent the heater coil from plugging.

SECTION 1: BEFORE INSTALLATION

Inspecting And Handling Your Filter:

Inspect the equipment for shipping damage. If damaged, notify the transportation company and request a damage inspection.

Handle the ﬁ lter with care. Damage can occur if dropped or set on sharp, uneven projections on the ﬂ oor. Do not turn the ﬁ lter 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 dealer will generally perform this service for you, and may send a sample to the factory for analysis and recommendations. Enter your below for a permanent record.

IMPORTANT NOTE:

Hydrogen sulﬁ de (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.

There are several different ﬁ lter media which can be used in this ﬁ lter. Each is designed to improve a particular aesthetic problem. NONE OF THEM SHOULD BE USED TO MAKE NON-POTABLE WATER SAFE TO DRINK. The following descriptions indicate not only what the media is designed to do, but also points out their limitations.

Neutralizer

NEUTRALIZATION (C or N Media) helps prevent corrosion of copper pipes and plumbing ﬁ xtures by correcting low pH (acidic) water conditions. This process is similar to adding lime to acidic soil or to taking an antacid. C Media is used for moderate pH correction (pH 6.0 - 6.8). N Media, which dissolves more rapidly, is used for more extreme conditions (pH 5.5 - 6.0 and as low as 5.0 under certain conditions). Both types of media are consumed during neutraliza-

tion and must be replenished periodically.

IMPORTANT NOTE

Since neutralizer media dissolves as it raises pH, it will increase the hardness. To help protect your water heater from the "scaling effect" of hard water, a Scale Inhibitor Filter or Water Softener should be installed after the neutralizer.

Activated Carbon

IMPORTANT NOTE

ACTIVATED CARBON ADSORPTION (A Media) is used to reduce chlorine, many impurities that give water an unpleasant taste or odor, and a wide variety of organic chemicals, including most pesticides, herbicides, and solvents (consult with manufacturer when attempting to reduce speciﬁ c chemical contaminants). Carbon contains millions of microscopic pores which chemically bond with these impurities to reduce them from the water. The capacity for adsorption is quite large but eventually the carbon must be replaced (the interval depends on the total quantity of impurities and amount of water used.)

Filtration Media

Filtration (F Media) is used when particle reduction is the only process required. The media is inert and does not react chemically with the water. GradedDensity media can be backwashed very efﬁ ciently and is particularly effective for the reduction of precipitated iron.

Activated Carbon

Activated carbon is generally used to reduce objectionable tastes and odors from water, chlorine being the most common. Activated carbon works primarily on the concept of adsorption. Each particle of carbon has numerous pores through which the water passes. It is in these pores that the reduction of unwanted constituents occurs. During backwash, these “collected” contaminants are knocked off and ﬂ ushed away to drain. Since the pores in the carbon are very important, the presence of sediment in the water — which can plug these pores — will greatly shorten the run time and life span of the carbon. The chlorine is reduced by a chemical reaction on the surface of the activated carbon, where the chlorine ions in the water are reduced to chloride ions, lessening the taste and odor issues associated with chlorine in the water.

The useful life of activated carbon will vary greatly depending on the water contaminants and amount of water ﬁ ltered per day. Rarely will the carbon last more than three (3) years.

Check Your Water Pressure And Pumping Rate:

Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage:

1) Minimum water pressure required at the ﬁ lter tank inlet is 20 psi (138 kPa).

CAUTION

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

IMPORTANT NOTE

If you have a municipal or a community water supply and daytime water pressure is 85 psi (586 kPa) or more, nighttime pressure may exceed 100 psi (689 kPa). Call your local water department or plant operator to obtain pressure readings. If you have a private well, the gauge on the pressure tank will indicate 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 sufﬁ cient for satisfactory BACKWASH. Although the density of a media normally determines the backwash rate, all the media discussed earlier will require the same ﬂ ow rate. These models require a 5 gpm rate (refer to SPECIFICATIONS AND OPERATING DATA for the backwash requirement for other models). To measure the pumping rate of your pump, follow these instructions:

a. Make certain no water is being drawn. Open spigot nearest pressure tank. When pump starts, close spigot and measure time (in seconds) to reﬁ ll

pressure tank (when pump shuts off). This ﬁ gure 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 ﬁ gure by CYCLE TIME and multiply by 60 to arrive at the PUMPING RATE in gallons per minute (gpm). To aid in you calculation, insert the data in the following formula:

DRAW-DOWN ______ ÷ CYCLE TIME ______ x 60 = PUMPING RATE ______ (gals.) (secs.) (gpm)

EXAMPLE: CYCLE TIME is 63 secs.; DRAWDOWN is 8 gals.; then PUMPING RATE equals:

8 gals. ÷ 63 secs. x 60 = 7.6 gpm

Locate Water Conditioning Equipment Correctly:

Select the location of your backwash system 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 drain.

3) Locate in correct relationship to other water conditioning equipment (Figure 1).

4) Locate the backwash system in the supply line BEFORE the water heater. Temperatures above 110°F (43.3°C) will damage the backwash system and void the factory warranty.

5) DO NOT install the backwash system 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 installation for easy servicing.

7) Provide a non-switched 110V, 60Hz (220V, 50Hz for speciﬁ ed systems) power source for the control valve.

WARNING

To reduce the risk associated with ingestion of contaminants:

• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

CAUTION

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

• Protect from freezing, relieve pressure and drain system when temperatures are expected to drop below 33°F (0.6°C).

• Do not install on hot water supply lines. The maximum operating water temperature of this ﬁ lter system is 110°F (43.3°C).

• Do not install systems in areas where ambient temperatures may go above 110°F (43.3°C) or below 40°F (4.4°C).

The Importance Of Your Pressure Tank:

A properly sized pressure tank will require a minimum pump cycle of 60 seconds to reﬁ ll from pump on-to-off pressure settings.

NOTE: If your pressure tank (or any part of your water system) is not functioning properly, corrective action MUST be taken before installation of your ﬁ lter.

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 backwash system, a larger model MUST be selected to accommodate the higher ﬂ ow rate plus the backwashing requirements of the backwash system. Consult your dealer for alternative instructions if the pumping rate is insufﬁ cient.

3) Remember that the backwash system 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 water heater.

CAUTION

To reduce the risk associated with property damage due to plugged water lines:

4) Before commencing the installation it is advisable to study the existing piping system and to determine the size, number and type of ﬁ ttings required.

WARNING

To reduce the risk associated with a hazardous voltage:

5) It is also advisable to sweep the ﬂ oor to eliminate objects that could pierce the brine tank.

Step 1

IMPORTANT NOTE

CAUTION

(a) Remove the control valve by removing the latch and clamp and pulling the valve up and out of the tank. Before loading

the media into the tank, the distributor must be all the way to the bottom of the tank. It is therefore recommended that the distributor be removed and the gravel dumped out and saved. The distributor tube should then be replaced in the empty tank making sure it rests on the bottom. Use the plastic cap provided to plug the distributor tube and prevent media from entering the distributor. Material lodge in the distributor tube can enter the control valve, thus damaging it. First, pour the gravel removed earlier back into the media tank and then add the media. Utilize the centering tool to help keep the distributor tube centered in the mineral tank opening to aid in mounting the control over the distributor tube. Never add media to a level above the line on the side of the tank. Additional media may have been shipped for future replenishment.

(b) Fill the tank with water. Lubricate o-ring on tank adapter with silicone grease and reinstall the CONTROL VALVE. Make sure

the distributor tube ﬁ ts into the valve body tube adapter protruding from the bottom of the valve body.

(d) If the BYPASS VALVE/YOKE ASSEMBLY is not factory pre-installed, attach to back of CONTROL VALVE using ADAPTER COU-

PLINGS, CLIPS and SCREWS.

IMPORTANT NOTE

Never add media above line indicated on side of tank. You may have received more media than required for the initial ﬁ ll, save extra media for future replenishment.

CAUTION

To reduce the risk associated with skin, eye, and respiratory tract irritation from dust from ﬁ lter media during installation:

• Utilize a NIOSH-approved dust ﬁ lter mask and appropriate eye protection when handling and pouring gravel and ﬁ lter media.

Figure 2. LATCH

Step 2

Shut off water at main supply. On a private well systems, turn off power to pump and drain pressure tank. Make certain pressure is relieved from complete system by opening nearest faucet to drain system.

CAUTION

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

• SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after water is shut off.

Step 3

Cut main supply line as required to ﬁ t plumbing to Inlet and Outlet of Bypass Valve Assembly.

Step 4

Solder or solvent weld 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.

CAUTION

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

• Do not use a torch or other high temperature sources near ﬁ lter system, cartridges, plastic ﬁ ttings or plastic plumbing.

• On plastic ﬁ ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic.

• Take care when using pliers or pipe wrenches to tighten plastic ﬁ ttings, as damage may occur if over tightening occurs.

Step 5

CAUTION

IMPORTANT NOTE

Attach Drain Line to Drain Line Fitting. To prevent back pressure from reducing the ﬂ ow rate below 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:

a. 1/2” ID lengths up to 15 feet and heights lower or slightly higher than the control valve.

b. 5/8” ID length up to 25 feet in length and up to 4 feet above the control valve.

c. For distances higher or longer than previously stated, relocate the ﬁ lter closer to the desired discharge point or consult

factory for advice. Avoid overhead drain lines as it may prevent desirable performance.

Avoid installing drain overhead or using ﬂ exible vinyl tubing, either may result in failure.

Some areas prohibit the use of ﬂ exible drain lines. Check with local code ofﬁ cials prior to installation.

CAUTION

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

• Installation must comply with existing state or local plumbing codes..

Figure 4. DRAIN

Step 6

Position Drain Line over drain and secure ﬁ rmly. To prevent back-siphoning of sewer water, provide an air-gap of at least 2 inches or 2 pipe diameters between end of drain hose and drain (See Figure 4). Do not raise Drain Line more than 10 feet above ﬂ oor.

Step 7

Make certain both inlet and outlet knobs of bypass valve are in "bypass" position. Turn on power to well pump or completely open main supply valve. Check for leaks and correct as necessary.

Step 8

a) Manually stage control to Backwash Position (See “How To Manually Backwash Your Filter At Any Time”, Page 2-4). Open Bypass Valve approximately 1/4 of

the way to full open (“Service” Position), allowing unit to ﬁ ll slowly. This will purge entrapped air in the bed.

b) Once a steady stream of water is ﬂ owing to drain, open Bypass Valve completely. Leave unit in backwash for at least 10 minutes OR until drain line water

runs clear, whichever is longer.

IMPORTANT NOTE

Filters containing activated carbon or F media must be saturated for at least 2 hours prior to subjecting the unit to full backwash ﬂ ow rates. Failure to do this may result in loss of mineral during initial backwash procedure.

Step 9

After this preliminary backwash, manually advance Control Valve to “Service” position and plug valve into a 110V, 60Hz properly grounded non-switched power source.

Step 10

Set time of day (See How To Set Time Control) and set Backwash Frequency (See Determining Backwash Frequency). Installation is now complete.

IMPORTANT NOTE

During the initial backwashings, a small amount of media may be observed in drain water. This is normal and beneﬁ cial for efﬁ cient operation of your ﬁ lter system.

Step 11

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.” Check drain water at end of rapid rinse cycle. If water is cloudy, repeat the backwash process.

IMPORTANT NOTE

Restore Fuel Supply or power to Water Heater.

Determining Backwash Frequency

The exact backwash frequency depends on the quality of the raw water, but it is recommended that ﬁ lters containing Activated Carbon, Birm, Filter Ag or Filter Sand be programmed to backwash at least once every six days. If pressure drop becomes excessive or contaminant reappears in the treated water before six days, increase the frequency. Filters containing Neutralizer should be backwashed every other day to prevent the media particles from “cementing” together. See “How to Set Time Control” for procedure.

3) Release the red button to again engage the drive wheel.

How To Set The Skipper Wheel

If you are setting the Time Control after Midnight but before Noon, the red pointer on the Skipper Wheel must be between two numbers (as shown). If you are setting the Time Control after Noon, but before Midnight, 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.

IMPORTANT NOTE

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 Backwash

Set the days that backwash is to occur by sliding tabs on the skipper wheel outward to expose trip ﬁ ngers. Each tab is one day. Extend or retract ﬁ ngers to obtain the desired backwashing schedule. Typically, these units are backwashed every third day. Consult your dealer for their recommendations for your water.

How To Manually Backwash Your Filter At Any Time

Turn the manual backwash knob clockwise until the knob engages the program wheel. This slight movement of the knob will start the backwash program.

The backwash knob will make one revolution in approximately 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 might be about 20 minutes in duration.

In any event, ﬁ ltered water may be drawn after rinse water stops ﬂ owing from the ﬁ lter drain line.

IMPORTANT NOTE

Should it be 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. is desired instead of 1:00 a.m., set the 12 hour gear one hour earlier than actual time.

Page 13

CAUTION

SECTION 3: MAINTENANCE

1) At least every six months you should check the time of day setting. Power outages will cause the unit to lose time.

2) If your unit contains Activated Carbon, you must replace the carbon and gravel underbed at least every three (3) years. Replacement may be required sooner if the taste and odor being reduced reappears in the treated water or pressure drop due to fouling of the media becomes excessive.

3) Filtration media will last an indeﬁ nite period of time. It may be necessary to replace it, if the pressure drop across the ﬁ lter becomes too great or ﬁ ltration results drop.

4) Neutralizer media, (C or N) must be replenished at least annually. Measure down from the top of the tank, comparing the current level with the mark. If the level is down by more than three (3) inches, add media

To Replenish (Rebed) Media

Pressure must be relieved on system by turning both Inlet and Outlet knobs of Bypass Valve to “Bypass” position and manually rotating Control Valve to “Backwash” position.

(a) Remove the control valve by removing the latch and clamp and pulling the valve up and out of the tank. Before loading the media into the tank, the dis-

tributor must be all the way to the bottom of the tank. It is therefore recommended that the distributor be removed and the gravel dumped out and saved. The distributor tube should then be replaced in the empty tank making sure it rests on the bottom. Use the plastic cap provided to plug the distributor tube and prevent media from entering the distributor. Material lodge in the distributor tube can enter the control valve, thus damaging it. First, pour the gravel removed earlier back into the media tank and then add the media. Utilize the centering tool to help keep the distributor tube centered in the mineral tank opening to aid in mounting the control over the distributor tube. Never add media to a level above the line on the side of the tank. Additional media may have been shipped for future replenishment.
