Pre-Installation

1. Review your packing list and make sure you have received all the parts before installation.
2. If you are going to be turning off the water to the house and you have an electric water heater, shut off the power to the water heater before beginning installation in case water heater is accidentally drained.
3. Pick a suitable location for your filter system on a dry level spot where it won’t be exposed to freezing temperatures. A minimum of 20 PSI is required. Maximum pressure is 90 PSI.
4. Get all of your plumbing parts together before beginning installation, and make sure you have received all of your packages before beginning or scheduling an installation. Installation typically takes 3 to 5 hours. However, after installation the Nitrate Filter must be allowed to run through a complete regeneration (backwash and rinse cycle) which can add 2 hours to the time.

Thank you for purchasing a Clean Water System!

• Please review this start‐up guide entirely before beginning to install your system, and follow the steps outlined for best results.
• Minimum pressure of 30 PSI recommended.
• Maximum pressure recommended 80 PSI.
• For indoor installation only.
• Protect from sunlight, rain, and freezing.

What to Do if Your Tank is Not Level Out of the Box:
Your black filter tank base is not glued to the bottom of your tank. Occasionally tank bases will become crooked during shipment. If you find that that your tank does not sit level on the floor, you can easily adjust it by holding the empty tank and knocking it on a concrete or solid floor once or twice to level it.

Pre-Installation

1. Review your packing list and make sure you have received all the parts before installation.
2. If you are going to be turning off the water to the house and you have an electric water heater, shut off the power to the water heater before beginning installation in case water heater is accidentally drained.
3. Pick a suitable location for your filter system on a dry level spot where it won’t be exposed to freezing temperatures. A minimum of 20 PSI is required. Maximum pressure is 90 PSI.
4. Get all of your plumbing parts together before beginning installation, and make sure you have received all of your packages before beginning or scheduling an installation.
5. Installation typically takes 3 to 5 hours. However, after installation the Nitrate Filter must be allowed to run through a complete regeneration (backwash and rinse cycle) which can 2 hours to the time.
6. After the system is installed and running, your water may be discolored particularly if you have older or corroded piping. This typically clears up over a day or two.

Best Practices for Piping & Drain Installation

1. Make sure to connect the Inlet from your water source and outlet, following arrows on control valve. Connect the External Flow Control fitting onto the Drain line.
2. Make sure there is a working gate or ball valve before the system and also one after as well as a bypass valve.
3. A hose bib (which is a faucet to which you can attach a garden hose) is strongly recommended after the Nitrate Filter and before the second ball valve. This makes it easy to rinse your new Nitrate Filter on start-up and gives you a place to test the water.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the 7500-REV2.5 control valve.
5. To connect drain line to drain, use an air-gap connection, so that if your sewer or septic tank backs up, it cannot cross connect with the drain tubing.
6. The pipe connectors are 1’ male pipe thread but you can add a reducer to reduce to ¾” pipe with common pipe fittings if needed.
7. Make sure bypass valves are closed (system is in bypass) when you first start installing and keep on bypass until you are ready to start it up with the first backwash.

How the Bypass Valve Works

• Turn knob so the valve is bypassed when installing.
• When you go to start up system turn the bypass SLOWLY to let water in and put in service.

Installation of Your System in Copper or Metal Piping Systems

• If your new filter system is to be installed in a metal (conductive) plumbing system, i.e., copper, or galvanized steel pipe, the plastic components of the system will interrupt the electrical continuity of the plumbing system.
• As a result, any stray currents from improperly grounded appliances downstream or potential galvanic activity in the plumbing system can no longer ground through the contiguous metal plumbing.
• Some homes may have been built in accordance with building codes, which encouraged the grounding of electrical appliances through the plumbing system.
• Consequently, the installation of a bypass consisting of the same material as the existing plumbing, or a grounded “jumper wire” bridging the equipment and reestablishing the contiguous conductive nature of the plumbing system must be installed prior to your systems use.
• This is simple and easy step to take if you are installing your water treatment system into copper piping.
• A simple ground jumper wire with a pipe clamp can be purchased at any Home Center, or hardware store etc. for a few dollars.

How Your Sediment Backwash Filter Works

• In the Nitrate filter, water enters the top of the tank and flows down through the media and up the distributor tube. Nitrates are attracted to the resin beads.
• During backwash, the water flow is reversed and water flows down the distributor tube and up through the media, expanding the Nitrate media, and removing sediment.
• After the backwash stage, salt brine is automatically drawn in from the brine tank which then slowly rinses through the Nitrate resin for 1 hour, allowing the Nitrates to be swapped out with harmless chloride ions.
• This entire automatic process, called ‘regeneration’ takes about 90 minutes.

The 7500-REV2.5 Control Valve tracks the amount of water that is used and will backwash based on gallons OR every 7 days, whichever comes first.

Filter Tank Assembly and Installation Instructions

1. Wrap the top of distributor tube with electrical or duct tape so that no gravelor Nitrate media will go down the distributor tube when adding the media.

2. Add the filter gravel that came with your order. You want the gravel to coverthe bottom distributor screen before adding the Nitrate media.

3. Next add Nitrate media. The tank should be about 2/3rds full of media, do not fill more than2/3rds, even if there is some media left over.

4. Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube when removing cap or tape.

5. Fill tank completely with water. This will allow the Nitrate Backwash Filter media to settle and reduce the need of purging the air out of the tank later. Allow nitrate to soak for at least 1 hour but 24 hours or more is OK.

6. Add a small amount of silicone grease to the inner O‐ring, where the distribution tube goes.

7. Next, install the top screen by inserting upwardsand rotating to lock in place. (This is a funnel‐shaped plastic screen that locks into the bottomside of control valve.

8. Lubricate the main tank O‐ring with silicone grease andscrew on the 7500‐REV2.5 control valve carefully. Do notuse pipe‐joint compound, vegetable oil, Teflon tape, orVaseline or other grease.

9. Connect bypass assembly with 1” pipe connectors tocontrol valve install black clips and make sure valve is inbypass position.

10. Insert meter cable into meter cable port on bypass.

11. Install inlet and outlet piping and hook up drain line tubing to drain.

12. If you are in earthquake zone, strap your backwash filter tank to wall with metal strapping.
    

13. Proceed to programming your 7500‐REV2.5 control valve timer and backwash frequency.

14.   IMPORTANT: you must program the time and then start a backwash and rinse. The filter system must be backwashed and rinsed several times before using. See following pages for instructions.

Determine Nitrate in Grains per Gallon and Set Capacity

• This refers to the number of gallons your 7500-REV2.5 is set to backwash.
• If we know your water’s nitrate and sulfate levels, we will preset this for you.

1. Step 1 : Note capacity of resin: 18,000 grains per cubic foot. For example, if you have a 2.0 cubic system, it has the capacity to remove 36,000 grains equivalent of nitrate and sulfate. These nitrate systems remove sulfate as well as nitrate. The nitrate resin capacity is rated as ‘grains per gallon’ of calcium carbonate, so we need to convert the sulfate parts per million to grains per gallon equivalent.

2. Step 2: Note the nitrate level in your well water as nitrogen: for example you have 44 PPM nitrate

3. Step 3: Note the sulfate level in your well water: for example you have 60 PPM sulfate

4. Step 4: Multiply the nitrate level by 0.81. Nitrate level = (Nitrate) ppm x 0.81 = ppm as CaC04

5. Step 5: Sulfate: Multiply the sulfate level x 1.04 (Sulfate) ppm x 1.04 = ppm as CaC04
   Example

6. 44 PPM x 0.81 = 36 grains

7. 30 PPM x 1.04 = 31 grains

8. Step 6: Compute the Total grains = 67 grains per gallon

• Total capacity of 2.0 Cubic Foot Nitrate system 36,000 grains divided by 67 grains = 537 gallons. Therefore set the Capacity to every 500 gallons.
• Set Regen Time This is the time your system will backwash.  Default is 2:00 AM
• Set Backwash Time Length Set for 10 minutes. This is the first cycle.
• Set B. S. R. Time “Brine Slow Rinse” time. Set for 60 minutes. This is where the potassium permanganate solution is drawn in to the system.
• Set Secondary Backwash Time Set for 8 minutes.
• Set Fast Rinse Time Set for 8 minutes.
• Set B. R. Time ”Brine Refill” – this is where the brine tank refills with water. Pick your nitrate filter size and enter minutes.

B.R. Times

0.75 CF| 8 MIN.
1.0 CF| 10 MIN.
1.5 CF| 11 MIN.
2.0 CF| 9 MIN.
2.5 CF| 11 MIN.
3.0 CF| 7 MIN.

• Maximum Days for Regen. Set to 4 Days. This refers to the days between each backwash. The recommended initial setting for the Nitrate Filter is every 4 days for families or heavy use and every 7 days for 1 to 2 persons in the home.

Start the First Backwash

1. After programming, the system must be run through 2 or 3 backwash/rinse regeneration cycles to clean the new filter media.
2. Start with both bypass valves in the Bypass Position.
3. Press the BACK/REGEN button once to enter the backwashing cycle.
4. When the backwash icon is displayed, slowly open the bypass to a quarter position to make the water flow into the tank and out the backwash drain line to drain.
5. After several minutes open bypass valve completely.
6. After the backwash, the system will automatically go into the fast rinse stage. The control valve will return to service status (indicated by the up flowing meter on the left).
