3. Mate the drain line adapter with the external flow control and brine line connection.

Installation of Your System in Copper or Metal Piping Systems:

If you are using copper or metal piping systems, follow these additional instructions:

• Do not sweat the copper pipe directly onto the 7500-C control valve to avoid damaging the valve body with excessive heat.
• Install unions and a bypass around the valve to allow for easy removal while still maintaining water flow (see Build Your Bypass).
• To connect the drain line to the drain, use an air-gap connection to prevent cross-connections in case of sewer or septic tank backups.

Best Practices for Piping & Drain Installation:
NOTE: YOU MUST USE THE UNION ADAPTORS TO CONNECT THE PLUMBING TO THIS UNIT. THESE UNIONS ARE SPECIFICALLY DESIGNED FOR THIS PURPOSE. WARRANTY WILL BE VOIDED IF DAMAGE OR CRACKING TO THE CONTROL HEAD IS CAUSED BY NOT FOLLOWING THESE INSTRUCTIONS. DO NOT USE ANY THREAD TAPE OR COMPOUND ON VALVE TO FITTING INTERFACE. THE SEALS ARE ALL THAT IS NEEDED. ONLY HAND TIGHTEN THESE FITTINGS TO THE VALVE AS WELL. THE OTHER END OF THE UNION IS A STANDARD 2” MNPT AND YOU CAN FOLLOW STATNDARD PLUMBING PRACTICES FOR THIS CONNECTION USING FLEX-LINES WITH WASHERS, THREAD TAPE, OR COMPOUND.

Making Connection to the Inlet Port using the Union Adaptor

Mating Connection to the Outlet Port using the Union / Flow Meter Adaptor

Mating the Drain Line Adaptor with the External flow control and Brine Line connection

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. Assemble all fittings into the 3 provided valve fitting prior to installion to the head. These seal with the blue seals and if overtightened can damage the valve body.
2. Make sure there is a working gate or ball valve before the 7500 Softener and also one after as well as a bypass valve. A hose bib (which is a faucet to which you can attach a garden hose) is strongly recommended after the Softener and before the second ball valve. This makes it easy to test the water before it enters your piping.
3. If you will be using copper piping, do not sweat the copper pipe directly on to the 7500-C control valve. Avoid heating up the control valve plastic with the torch.
4. You should install unions and a bypass around the valve, so that you can remove it and still have water (See Build Your Bypass).
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.

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.

How Your Softener Works

Fig. 1: In the softener, water enters the top of the tank and flows down through the media and up the distributor tube.

• Hardness minerals are drawn to the resin beads in the softener where they are removed.
• During regeneration the first cycle in the process backwashes and cleans the softener resin. Water flow is reversed and water flows down the distributor tube and up through the media, lifting and expanding the softening media, and removing any trapped particles.
• After the backwash stage, salt brine is automatically drawn in from the brine tank which then slowly rinses through the softening resin for 1 hour, allowing the hardness minerals to be swapped out with harmless sodium or potassium ions.
• This entire automatic process, called ‘regeneration’ takes about 90 minutes. Typically, the softener filter is set to regenerate based on gallons used and time to occur during the middle of the night when no water is being used.

Assembly and Installation Instructions

1. Wrap the top of distributor tube with electrical or duct tape so that no gravel or Carbon 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 cover the bottom distributor screen before adding the Resin media. (Note: for 10 cu/ft systems, place the two bags of ¼” x ½” gravel (larger size) into the tank first then followed by the two bags of 1/8” x ¼” gravel (smaller size).
3. Next add the Resin media. 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. Lubricate the main tank O-ring and screw on 7500 control valve carefully. Do not use pipe-joint compound, vegetable oil, Teflon tape, or Vaseline or other petroleum greases to lubricate tank threads.
7. Connect your brine line tubing to the brine tank. Fill your brine tank with coarse water softener salt.
8. Next, install the top screen mount to the control valve by aligning the five-hole pattern and installing the machine screws out of your kit.
9. Thread the top screen to underside of 7500-C control valve. The Control valve is now ready to install onto the cylinder. Do not use wrenches hand tighten only.

Programming Your Valve and Setting Time and Days for Backwash

Next, you will need to program the system to work as a Softener. There are a few settings that must be changed before the system can be put into service. Plug in the control valve and begin the programming instructions

IMPORTANT: Before any operation, the valve menu must be unlocked. If the button lock indicator is displayed, press and hold both the Up and Down buttons for 5 seconds. A sound will indicate the menu is unlocked. The menu will re-lock automatically after 1 minute of inactivity.

1. To begin programming your valve, unlock the menu and press the Menu/Confirm button. This puts the valve into program display mode, indicated by the Enquiry/Setting icon being displayed. The Enquiry/Setting icon is displayed whenever you are changing the parameter of a programming mode.
2. The sequence of programming modes is shown in the diagram below. To switch between modes, press the up or down button according to which direction your mode is. The modes can only be changed when the Enquiry/Setting button is displayed, and you are not currently modifying any other parameter.
