Pre-Installation
1. Review your packing list and make sure you have received all the parts before beginning 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 accidentially
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. Installation typically takes 3 to
5 hours. However, after installation the system must be allowed to run through a complete backwash
and rinse cycle.
5. After the system is installed and running your water may be discolored or full of sediment/rust,
particularly if this is older or corroded piping. This typically clears up over a day or two.
Best Practices for Piping & Drain Installation
1. See typical installation (see Fig 2). The system is installed after the pressure tank.
2. Make sure to connect the IN pipe to the Fleck 7000 inlet and the OUT pipe to the outlet (see Fig 2). As
you face the Fleck 7000 control from the front, the water enters on the right and exits on the left.
From the back (see Fig 2) the water enters on the left. The inlet and outlet are attached to the bypass
valve which is marked with arrows as well.
3. Make sure there is a working gate or ball valve before the Fleck 7000 system and also one after as
shown in Fig 2. The pressure gauges are optional and perhaps not necessary but a hose bib (which is
a faucet that you can attach a garden hose to) is strongly recommended after the neutralizer filter
and before the second ball valve. This makes it easy to rinse your new filter on start-up and gives you
a place to test the water before it enters your household plumbing. It also makes it much easier to
perform maintenance in the future.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the Fleck 7000 control
valve. Avoid heating up the Fleck 7000 control valve plastic with the torch.
5. If have copper pipe before the neutralizer and it is too difficult to change out, you may still experience
some copper staining of fixtures and have a copper residual in the water because this section of pipe
will still have acidic water flowing through it. We recommend PEX or PVC pipe up to the neutralizer
and then copper after it, if you have copper plumbing.
6. You do not need unions to install your Fleck 7000 control. If you need to remove it, the Fleck 7000
has quick-release couplings that make it easy to put the system on by-pass and remove the filter
system from the piping.
7. The drain line tubing (not supplied) is connected to a drain from the drain outlet using flexible ½” ID
tubing. Note that the drain can run up above the Fleck 7000 control and into a drain, it does not

have to drain down as the filter backwashes under line pressure from your well pump. Most plumbing
codes require an air-gap connection, so that if your sewer or septic tank backs up it cannot cross
connect with the drain tubing.
How Your Neutralizer Works
See Fig 1. In your neutralizer, the water enters the top of the tank and flows down through the media and up
the distributor tube. The downflow type neutralizer removes sediment and can be backwashed, which
cleans and re-classifies the Calcite, preventing channeling. During backwash, the water flow is reversed and
water flows down the distributor tube and up through the media, lifting and expanding the Calcite media.
During the backwash the Calcite is cleaned by the action of the water flowing through it.

Assembly and Installation Instructions
1. By hand, unscrew the entire Fleck 7000 control valve from the top of the tank (if it was shipped
screwed on). If not already done, make sure the blue cap is on top of the distributor tube, or wrap
the top of distributor tube with electrical or duct tape. You do not want Calcite to go down the
distributor tube.
2. Next, add Calcite or Calcite-blend media. If you are using a blend of Calcite and Corosex, make sure
to read page 11 for more information on using and adding blends.
3. Remove cap or tape from the top of distributor tube. Be careful not to pull up the distributor tube
when removing cap or tape.
4. If possible at this point, fill tank completely with water. This will allow the neutralizer media to settle
and eliminate the need for purging air out of the tank later.
5. Attach plastic top screen to the under-side of the Fleck 7000 control valve. It is a funnel-shaped
plastic screen that snaps on to the control valve and prevents resin from being backwashed out to
drain during the regeneration cycles.

6. Do not use pipe-joint compound, Teflon tape, Vaseline or other petroleum greases to lubricate tank
threads. Do not over-tighten when threading Fleck 7000 control valve on to tank. Do not allow hard
piping to cause stress on the Fleck 70000 valve, the pipes should not be pulling down or up on the
valve. Flexible connectors avoid this problem and are recommended.
7. See how the Fleck by-pass is connected. Note that Items 2 in Fig 4 (below) are the pipe-connectors
and the other end is what gets attached to the control valve. Items 3 are the red clips that hold the
pipe connectors to the by-pass valve - we include two extra red clips with the pipe connector kit.
Your Fleck 7000 is usually shipped in the by-pass position.
Fig 3 - Bypass Assembly
8. Lubricate the by-pass valve o-rings with vegetable oil or silicone grease and connect the bypass
assembly to the Fleck 7000 control by sliding the bypass valve firmly into the body of the Fleck7000.
Once the bypass is in far enough, you will be able to insert the red connector clips. DO NOT USE
PETROLEUM GREASE ON ANY PART OF THE FLECK 7000 CONTROL VALVE.
9. Next lubricate the end-connectors (#2 in Fig 4) with silicone grease or vegetable cooking oil and insert
them into the bypass valve, then insert the red clips (#3 in Fig 4).
10. Note that the Fleck 7000 is usually shipped in the bypass position. There is a bypass valve knob on
both the inlet and the outlet (#1 in Fig 4). You can easily tell if it is in bypass because the two holes on
the bypass knob will be in the vertical position. If the valve is in the Service position (which is the
filtering position or ‘in service’ position) the holes will be in the horizontal position. Make sure both
sides are in the by-pass position (Fig 5, below).

Fig 4 - Bypass and Service Modes
11. Do NOT remove the red clips in order to put the bypass valve in either bypass or service; it is neither
necessary nor desired to remove the red clips on the bypass valve hand knobs.
12. Now install your water pipes to the Fleck 7000 bypass end connectors. Make sure the inlet is
installed to the 'In" pipe connector on the bypass valve and outlet is on the “Out” connector.
13. Connect some flexible tubing from the drain connection on the Fleck 7000 control valve to a suitable
drain such as a septic tank or sewer drain. It is OK to run the drain line up and over the Fleck 7000
Neutralizer filter up to 4 feet above the top of the tank. If the drain line will be more than 20 feet,
use larger diameter tubing such as ¾” or 1”. Note that it is desirable to be able to run the drain line
into a bucket in order to test the backwash flow rate in the future. This is why hard piping the drain
line is discouraged: however, if you do use hard PVC piping for the drain line, and you are able to
remove the hard PVC drain piping and attach flexible tubing should you ever desire for testing
purposes, it is OK to use rigid PVC pipe for the drain. Make sure the drain tubing is firmly clamped to
the barbed fitting with a hose clamp to prevent leaks.

Fig 5 –Backwash Drain Flow Control Installation
14. Smaller neutralizer systems use a 90 degree fitting, while the larger sizes use a straight fitting. For the
straight fitting, the flow control goes in first, and then the fitting. Then simply connect your plumbing
using Teflon tape on the threads.
15. Plug your Fleck 7000 control valve into an outlet. Your Neutralizer 7000 control valve is already pre-
programmed. All you need to do is to set the time of day, and then set the number of days the
Neutralizer filter will run before it backwashes and regenerates automatically. The default number of
days between back wash is 7.
16. Press and hold either the Up or Down button until the programming icon replaces the service icon
and the parameter display reads TD. Set the time of day by pressing the up or down arrows until it is
the current time of day. When the desired time is set, press the Extra Cycle button to resume normal
operation, or wait 5 seconds and the unit will return to normal operation if no button is pressed.
17. Hold down the Up and Down buttons at the same time for 5 seconds. Set the number of days
between backwashes, typically for 7 days. If your water is very clean (no sediment or iron) you can
set the backwash frequency to as little as every 14 days, but if not it is best to leave it to backwash
every 7 days.
