7500-REV2.5 Tannin Filter Installation & Startup Guide
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‐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.
