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. Installation typically takes 3 to 5 hours. However, after installation the Tannin Filter must be allowed to run through a complete regeneration (backwash and rinse cycle) which can 2 hours to the time.

5. 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 Tannin Filter and before the second ball valve. This makes it easy to rinse your new Tannin 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-REV4 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 Tannin Filter Works
In the Tannin Filter, water enters the top of the tank and flows down through the media and up the distributor tube. Hardness minerals 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 Tannin resin, and removing sediment.
After the backwash stage, salt brine is automatically drawn in from the brine tank which then slowly rinses through the Tannin Resin for 1 hour, allowing hardness minerals (calcium, magnesium) to be swapped out with sodium ions in a process known as ion-exchange.
This entire automatic process, called ‘regeneration’ takes about 90 minutes.
The 7500-Rev4 Control Valve tracks the amount of water that is used and will backwash based on gallons OR every 7 days, whichever comes first.

Diagram of Typical Installation Well Water
If water is high in hardness (over 5 grains per gallon) a water softener is recommended.

Tannin Tank Assembly and Installation Instructions

1. Wrap the top of distributor tube with electrical or duct tape so that no gravel or Tannin resin 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 cover the bottom distributor screen before adding the Tannin resin.
3. Next add Tannin resin. The tank should be about 2/3rds full of media, do not fill more than 2/3rds, 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.
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 upwards and rotating to lock in place. (This is a funnel-shaped plastic screen that locks into the bottom side of control valve.
8. Lubricate the main tank O-ring with silicone grease and screw on the 7500-Rev4 control valve carefully. Do not use pipe-joint compound, vegetable oil, Teflon tape, or Vaseline or other greases to lubricate tank threads.
9. Connect bypass assembly with 1” pipe connectors to control valve install black clips and make sure valve is in bypass
10. Install inlet and outlet piping and hook up drain line tubing to drain.
11. Insert meter cable into meter cable port on bypass
12. If you are in earthquake zone, strap your backwash filter tank to wall with metal strapping.
13. Connect black 3/8” tubing to brine tank.
14. Hook up drain line tubing to drain. If needed heat up the tubing with warm water or a hair dryer to make it easier to slip over the barbed fitting on the drain port.
15. Proceed to programming your 7500-Rev4 control valve timer and backwash frequency.
16. IMPORTANT: you must program the time and then start a regeneration backwash and rinse. The tannin must run through one regeneration cycles. See following pages for instructions.

Programming Your Valve and Setting Time and Days for Backwash

How to Start a Manual Backwash: Press the Back / Regen button
Pressing “Back Regen” at any time results in an immediate manual regeneration.

2. Start with both bypass valves in the Bypass Position.
3. Press the BACK/REGEN button once to enter regneration.
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 3 or 4 minutes open bypass valve completely.
6. Allow to complete regeneration process, about 90 minutes.

CONGRATULATIONS, YOU ARE DONE SETTING UP YOUR SYSTEM!
