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
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 Sediment Filter 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 or
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.
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 7500 Sediment Filter and also one after.
A hose bib (which is a faucet to which you can attach a garden hose) is strongly recommended after
the Sediment Filter and before the second ball valve.
3.
Your 7500‐S Sediment Backwash Filter must be backwashed and rinsed several times on start‐up.
During the initital backwashes and rinses, keep the valve AFTER the system closed. After
backwashing and rinsing, open up hose bib after system and before closed valve, and run the water.
If water is not clear, perform additional backwash and rinses.
4.
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 control valve plastic with the torch.
5.
You should install unions and a bypass around the valve, so that you can remove it and still have
water (See Build Your Bypass).
6.
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.
