PENTAIR Whole House Air Injection Iron Reduction Systems Owner’s Manual

PENTAIR Whole House Air Injection Iron Reduction Systems

IMPORTANT INFORMATION

• Read these instructions carefully and determine the location of all system components before beginning installation.
• Check all applicable plumbing, building, and electrical codes for installation compliance.
• Install the system on the main water supply.
• The use of plumbers tape and/or pipe thread seal paste will be needed on all threaded connections.
• To condition all water in the home, install the Filter System close to the water supply inlet, and upstream of all other plumbing connections, except outside water pipes. Outside faucets should remain on unfiltered water.
• Systems that contain electronic components cannot be installed outside in uncovered areas.

WARNING

Installing this system in a metal (conductive) plumbing system, i.e., copper or galvanized metal, will interrupt the continuity of the plumbing system and grounding source in some homes. If your home’s electrical appliances are grounded through the plumbing system, you will need to install a bypass that consists of the same material as the existing plumbing or a grounded “jumper wire” to bridge the equipment and re-establish the contiguous conductive nature of the plumbing before using this Pentair system. Failure to do so can result in errant electricity from improperly grounded appliances or potential galvanic activity in the plumbing system, which could increase the risk of fire or injury while using your home appliances. Please consult a licensed electrician before attempting to install.

CAUTION

When adding a filtration/softening system to homes/buildings supplied by well water, the system should be installed following the pressure tank. DO NOT USE this system for pneumatic or hydropneumatic applications. If you are using a booster pump, then install this system following the booster pump. If you have questions, please call customer service.

• Approximate capacity between filter regeneration cycles.

System Tested and Certified by WQA to NSF/ANSI 372 for Lead Free Compliance only.

Order Number for the replacement media: 14816

ENVIRONMENTAL REQUIREMENTS

Location: The water filter and control cannot be exposed to outdoor elements, such as direct sunlight or atmospheric precipitation. The system may be installed in a covered, open-air structure such as a carport, residential or commercial building. Weather covers are also available through Customer Service ( Part No. 72370 ).

PRE-INSTALLATION INSTRUCTIONS

• Do not install this system where water is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
• This system must be installed in an area that is not affected by extreme heat, cold or the elements. The selected installation area must be adequate for easy service of all parts.
• This system must be installed in accordance with all applicable state and local laws and regulations.
• This system is designed to treat cold water only and can be installed on any cold water supply.

MAINTENANCE REQUIREMENTS

• Clean the backwash flow control.
• Verify that the flow meter is functioning correctly. Clean the impeller, if necessary.
• Verify the programming of the control. Reprogram, if necessary.
• Verify the minimum and maximum water pressure. Install a pressure reducer, if necessary.
• Replace the filter media every three to five years. Systems used for treatment of high iron will require replacement of the filter media more often. Call your local dealer to replace the filter media (part # 14816).

INSTALLATION INSTRUCTIONS

SAFETY PRECAUTIONS

• To prevent accident or injury, do not hoist the unit over your shoulder. Use a hand truck to transport the unit.

Notice: Do not lay the unit on its side during transportation and/or installation.

• Wear safety glasses and work gloves during installation and service.

TEST THE RAW WATER

• Test the raw water supply to ensure it meets the “Application Limitation”.

CHECK WATER PRESSURE

• Use a pressure gauge to confirm that the water pressure does not exceed 120 psi. If the water pressure does exceed this limit, install a pressure regulator on the inlet pipe of the unit. The minimum pressure for a filter is 20 psi. 60 psi is the optimum operating pressure.

CHECK THE WELL PUMP FLOW RATE

• Proper backwash is required to maintain the life of the filter media. If installed on a well, check to make sure the well pump can provide a drain flow rate of 5 gallons per minute.

LOCATE A SITE FOR THE UNIT

• There are three primary requirements needed for a site: the main water source, a drain (the drain may be a floor drain, a sewer trap, utility sink, vent stack, dry well, etc., depending on local plumbing codes) and an electrical connection. Locate the system as close to these items as practical. Avoid drain lines over 25 feet long. In most applications, bypass any outside faucets.
• Place the unit in the desired location. The location must have a level, smooth surface.
• If the system is located outdoors, protect the unit from direct sunlight. (Direct sunlight can damage the fiberglass and other system components.) If necessary, build a box or shed.

_ Notice: _The system can only be installed outdoors in climates that do not reach freezing levels.

TURN OFF THE WATER AND DRAIN THE PLUMBING

• Turn off the water at the meter or the pressure tank.
• Drain all the pipes. Do not sweat the pipes with water in them; steam will damage plastic parts in the valve.
• To drain the plumbing system, open all the faucets in the house and flush the toilets. This procedure will allow air to enter the plumbing system. The water will drain out of the lowest faucet or outlet.

BYPASS THE OUTSIDE FAUCETS

• When possible, it is best to bypass the outside faucets. However, in some cases the outside faucets can not be accessed. In this situation the bypass valve should be used whenever watering outside for extended periods of time. If the installation is outside or in a garage a faucet can be installed on the inlet water side to provide an option for untreated water.

INSTALL THE CHECK VALVE

• Install the check valve (supplied) on the raw water supply feeding the tank. The check valve must be installed in vertical, upflow position with a minimum 12” water column above the check valve (Part No.19736). Please see figures below.
• Connect the treated water pipe to the OUTLET pipe connection of the bypass valve. When looking at the front of the unit, the outlet is the pipe connection on the RIGHT side of the valve.

CONNECT THE PLUMBING TO THE BYPASS VALVE

• Do not point the soldering torch directly at the system. The thermoplastic material will last a lifetime, within normal operating temperatures, but will melt in a torch flame.
• To prevent hot water from backing up into the conditioner, avoid short connections of pipe between the conditioner and the hot water heater. If you can’t avoid a short connection, move the equipment to another location. As a last resort, install a check valve. If the check valve causes “water hammer”, install a water hammer suppressor.
• Connect the raw water pipe to the INLET pipe connection of the bypass valve. When looking at the front of the unit, the inlet is the pipe connection on the LEFT side of the valve.
• Connect the raw water pipe to the OUTLET pipe connection of the bypass valve. When looking at the front of the unit, the inlet is the pipe connection on the RIGHT side of the valve.

TURN ON THE WATER AND TEST FOR LEAKS, FLUSH THE PLUMBING

• Before turning the water back on, place the system in the bypass position, then close all of the faucets except one cold water tap from a bath tub.
• Turn the water on slowly and allow the water to flow out the bath tub for several minutes to remove any dirt, solder, glue, etc. from the plumbing system.
• Once the water runs clear, turn the bypass valve handles to the service position and allow the water to fill the system. It is common for the first few gallons of water to show some color ( range to brown) for a few minutes. Once the water runs clear shut off the bath tub.
• The system will now pressurize allowing you to check for any leaks.

FLUSH THE REMAINING DEBRIS FROM THE SYSTEM

• To flush the remaining untreated water from the plumbing, turn on all the faucets in the house and flush the toilets (approximately two to three minutes per faucet).
• Run hot water in the bathtub to remove any remaining untreated water.

INSTALL THE DRAIN LINE AND AIR GAP

• Using the supplied drain line fitting use plumber’s tape on the threads and attach to the top of the valve. Run 1/2 inch ID flexible drain line tubing (not supplied) to an appropriate drain. Most local codes require an air gap. See pictures on the next page. The Air-Gap is not provided with the product.

Notice

Drain line may be plumbed with rigid pipe or PEX, if required by local code. The drain connection on the valve will accommodate any standard 3/4 inch NPT fitting.

Notice

The regeneration cycle is a simple backwash to refresh the filter bed, followed by an intake of air to establish an air head in the tank. Since no regeneration chemicals are added, the discharge water may be drained to the outside and used for irrigation in climates where freezing is not a concern. Please note that iron in the drain water may cause staining, so avoid situations where the water may splash onto walls, vehicles, patios, etc.

INSTALL THE AIR CHECK ASSEMBLY

Air check assembly should be assembled as shown below, with the screen pointing up. Be sure that the molded arrow on the air check valve points down.

Special attention for situations where a Filter and a Softener are installed together:

CONTROL INFORMATION

POWER ON LED

A green LED is ON when power is applied to the control and the microprocessor is operating properly.

SERVICE REQUIRED

If the message “For Service Call” or “Service Required” displays in the window of the control without showing the time of day, the control valve has encountered a problem, such as failure to reach the proper position during regeneration. The valve, the motor assembly, and board must be checked to diagnose and fix this problem.

Notice: It is normal for the message ‘For Service Call’ followed by a phone number to scroll across the second line of the display. The time of day & capacity remaining will appear on line 1 during normal operation.

TIME CLOCK

The time clock maintains the time of day for an extended period of time in the event of power loss. A super capacitor provides this function and eliminates the need of a battery. In the event the power is off past the charge of the capacitor only the time of day is lost. The rest of the programming is stored in the memory and will not need to be reprogrammed. When the power is restored, the clock will restart at 8 AM and will need to be reset.

REGENERATION

Once an immediate regeneration is requested, a complete regeneration must occur to clear the request. Once the regeneration starts, it must finish or the computer board will not clear. Manually walk (scroll) the control through regeneration to clear the computer board. If the regeneration is aborted and the request is not cleared, another immediate regeneration will occur.

HIGH-SPEED MOTOR OPERATION IN THE REGENERATION MODE

High-speed motor operation is achieved while stepping the control through the regeneration cycle. Pressing the scroll button a second time, while in regeneration, activates the higher speed.

PROGRAM LEVELS

To enter any of the program levels, the control must display the time of day and gallons of capacity remaining (Service Mode). The system have three program levels available:

1. The Installer’s Level: To access the Installer’s Level, you must enter the five key sequence code located on page 10. Please refer to pages 10 – 12 for programming information.
2. The End User’s Level: The End User’s Level does not require a special code to access. Please refer to page 14 for programming information.
3. The Diagnostic Level: Please refer to page 15 for information.

When a whole house filter and a softener are installed side by side, the preferred approach is to run a separate drain line from each unit all the way to the point of termination. If this is not done, there is the potential for drain water from the filter to back feed through the softener and overfill the brine tank, especially when drain lines are run overhead. (Please note that back feed goes only into the brine tank, not the service line.)

If circumstances require you to tie the drain lines together, please use one of the following methods to avoid back feed issues:

• Option 1: Run the drain lines from both systems to the point of termination, and tee them together before the air gap. (See figures below)
• Option 2: Install a PVC check valve with a light spring on the Softener side to prevent backflow to the Softener. (See figure below)

HOW TO PROGRAM THE INSTALLER’S LEVEL

KEY BUTTONS

1. SCROLL BUTTON
2. UP ARROW
3. DOWN ARROW

• To begin, verify that the control is in Service Mode.
  • Time of Day GL Remaining
• Press the DOWN ARROW and hold it for 5 seconds; the control will display:
  • System Check

Within 10 seconds, enter the following key sequence:

• DOWN ARROW

• DOWN ARROW

The control is now in the Installer’s Level. Use the SCROLL BUTTON to advance through the different settings. The following settings are available in the Installer’s Level:

1. CAPACITY

   • The control will display:
   • Capacity: 1000 GL3
   • Press the UP or DOWN ARROW to change the volume of treated water between regenerations. The gallons are in increments of 100. The setting range is 100 to 999,999 gallons (maximum limit).
   • Determining the proper regeneration frequency is based on the amount of daily water use and the amount of Iron in the water. There is no exact science here and its best to reply on personal experience. In most Iron applications, regenerations no more than three days apart is the normal treatment. When sulfur is present, daily regeneration maybe needed depending on the amount. See DAYS OVERRIDE. Press the SCROLL BUTTON to advance to the next setting.

2. RESERVE CAPACITY
   The control will display:

   • Rsrv: 200 GL Fxd
   • To adjust the reserve, press the SCROLL BUTTON. Use the UP OR DOWN ARROW to set the reserve capacity in increments of 10 gallons, up to 70% capacity of the bed.
   • To calculate the reserve capacity, take the number of people in the home and multiply it by 70 gallons per day. The reserve capacity will equal one day of water use.
   • Example: 3 people X 70 gallons per day = 210 gallons (suggested reserve capacity)
   • If you prefer, you can select a Variable Reserve. While at the Reserve screen when “Fxd” is flashing,press the UP or DOWN ARROW. The control will display:

• *  **Rsrv:** Variable

• The reserve capacity will be calculated automatically, based on the daily water consumption. The initial setting is 25% of the capacity, which will adjust over time to accurately reflect daily water use.
• Press the SCROLL BUTTON to advance to the next setting.

TIME OF REGENERATION

The control will display:

• * Regen @ 2:00 am

• Press the UP or DOWN ARROW to adjust the time of regeneration.
  • Regeneration should be set for a time when water use is minimal. 2:00 AM is good for most households.

Notice: The system diverts untreated water to the home during regeneration. If any water is drawn during regeneration, some untreated water will enter the plumbing system and possibly the hot water tank. Keep in mind that the regeneration cycle can last up to two hours after the starting time.

• Press the SCROLL BUTTON to advance to the next setting.

DAYS OVERRIDE

The control will display:

Override: 3 days

• Press the UP or DOWN ARROW to set the number of days between regenerations. The setting range is 1 to 7 days. 3 days is a good starting point for most installations.

Notice: This setting “overrides” the flow meter in the sense that it forces the system to regenerate after the selected number of days has passed, even if the gallon capacity setting has not been reached.

CYCLE 1 – BACKWASH
The control will display:

Backwash: 10 min

• Press the UP or DOWN ARROW to change the length of the backwash cycle. The setting range is 5 to 99 minutes. We do not recommend a backwash of less than 10 minutes for an iron filter. Press the SCROLL BUTTON to advance to the next setting.

CYCLE 2 – AIR FILL

The control will display:

• AIR FILL: 13 min
• Press the UP or DOWN ARROW to change the length of the air fill cycle. The setting range is 8 to 30 minutes.

Notice: This cycle controls the amount of air head in the tank. 13 minutes is a good starting point for installations. Press the SCROLL BUTTON to advance the next setting.

1. CYCLE 3 – RINSE
   The control will display:

   • RINSE: 3 min
   • Press the UP or DOWN ARROW to change the length of the fast rinse. The setting range is 0 to 99 minutes (maximum limit).

Note: In most applications, this setting will not need adjusting. Press the SCROLL BUTTON to advance to the next setting.

SERVICE PHONE NUMBER

The control will display:

1. Change Phone? No
2. 000-000-0000

• If you do not want to change the phone number, leave this setting at NO. Press SCROLL to advance to EXIT.
• To change the number, select YES; Press the UP or DOWN ARROW and then enter the service phone number. Press SCROLL to advance through the digits.
• After setting the number, press SCROLL to exit the installer’s level, the screen will display:
  • Exit
• Press the UP or DOWN ARROW to exit the Installer’s Level.

Notice: If you need to recheck settings or make a change, pressing SCROLL when “EXIT” is displayed will take you back to the start of Installer Settings.

Caution: TO ACTIVATE THE NEW SETTINGS, YOU MUST EXECUTE A COMPLETE REGENERATION. IF YOU DO NOT MANUALLY REGENERATE THE SYSTEM, THE SETTINGS WILL NOT BECOME ACTIVE UNTIL THE UNIT HAS COMPLETED THE NEXT SCHEDULED REGENERATION.

SYSTEM START UP INSTRUCTIONS

Notice: To avoid damage, do not regenerate the filter for a minimum of 24 hours!

1. Confirm the system is plumbed correctly: inlet on left, outlet on right – Is the drain properly connected? If there is a softener or any other filter place the system(s) on by pass. Follow the softener start up instructions after the Iron Filter is complete
2. Open a faucet without an aerator such as a bath tub or outdoor faucet and close all others. Turn on the water and allow the system to rinse for a minimum of 10 to 15 minutes to get rid of all fines. (You can’t rinse too much)
3. Advance to backwash: Press SCROLL button 2 times. The display will start a 10 second count down. At zero the motor will start and advance valve to cycle 1 (backwash). Allow the air to purge (2 to 3 seconds) then immediately advance the valve to the next cycle by pressing and holding briefly the SCROLL button. The Mineral takes 24 hours to saturate so we advance quickly to avoid the mineral from lifting.
4. Once the motor starts, release the SCROLL button. The valve will advance to cycle 2 (AIR FILL). The system will pull air from outside through the air check valve. Make sure it advances through the whole AIR FILL step to get the initial air in the tank by allowing the system to complete the cycle.
5. Flush the remaining water from system and verify gallon counter: while the water is flowing, check the gallons remaining on the home screen and verify that the number is decreasing. This will confirm that the system is counting gallons. Run a faucet on the hot water side until it runs cold to drain the hot water tank.

Notice: This system is an aeration-type system so it is to be expected that the water will be cloudy and sometimes milky, especially when using hot water. This is normal and by allowing the water to sit for a few minutes the air will disappear.

HOW TO PROGRAM THE END USER’S LEVEL
