What to Do if Your Tank is Not Level Out of the Box
• Tank sizes for 2.5 Cubic Foot models and below: 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 rapping it on a concrete or solid floor once or
twice to level.

System Installation Steps Overview
1. Put gravel in first, then Carbon Media.
2. Add ½ cup household bleach down center distributor tube and fill tank with clean water.
The longer it soaks while you are doing everything else, the better.
3. Make the plumbing connections from your existing system to the filter, installing a 3-valve
bypass around the 7500-S filter backwash control valve.
4. Screw on, attach the control head to the tank.
5. Install the drain Line tubing and external flow control assembly (if using for model 2.0 CF or
larger)
1. Plug in the power supply and program the valve.
2. Follow the instructions to put the system online, backwash and rinse several times and
check for leaks.
Pre-Installation
1. Review your packing list to 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.
3. Pick a suitable location for your filter system on a dry level spot where it won’t be exposed
to freezing temperatures, direct sunlight, wind or rain.
4. Get all of your plumbing parts together before beginning installation.
5. After the system is installed and running, your water may be discolored, or full of Carbon or
rust, especially if you have older or corroded piping. This typically clears up over a day or
two.

Best Practices for Piping & Drain Installation
1. See typical installation (Fig 5). The Carbon Backwash filter is installed after pressure tank
on well systems.
2. Install on a level floor or surface.
3. Filter system must be installed at least 10 feet ahead of inlet to water heater to prevent
damage due to back-up hot water or use a check valve to prevent hot water back-up.
4. DO NOT install the unit in an area of direct sunlight or expose to freezing.
5. Locate the unit near an unswitched, 120 volt / 60 Hz grounded electrical outlet.
6. Make sure to connect the IN pipe to the 7500-S inlet and the OUT pipe to the outlet and
install a 3 valve bypass around the 7500-S control valve.
7. Make sure there is a working gate or ball valve before the 7500-S Carbon Filter and also one
after as shown in Fig 4. The pressure gauges are optional. A hose bib (which is a faucet that
you can attach a garden hose to) is strongly recommended after the 7500-S Filter and
before the second ball valve, for rinsing and sampling water.
8. If you will be using copper piping, do not sweat the copper pipe directly on to the 7500-S
control valve. Avoid heating up the 7500-S control valve plastic with the torch.
9. The drain can run up above the control head and out to a drain, although this may require
installing a one way, flapper-stlye check valve.
10. 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 (if running tubing into the washing
machine drain pipe, for example)
11. Your 7500-S filter must be backwashed and rinsed 2 – 3 times on start-up. During the initial
backwashes and rinses, keep the valve after the system closed.
12. After backwashing and rinsing, open the hose bib after the system and before closed valve,
and run the water until it is clear.
