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. Installation typically takes
3 to 5 hours. However, after installation the Carbon 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.
See typical installation on page 7 (Fig 2). The Carbon filter is installed after the pressure tank.
2.
Make sure to connect the IN pipe to the 7800 inlet and the OUT pipe to the outlet (see Fig 2). As
you face the 7800 control from the front, the water enters on the right and exits on the left.
From the back (see Fig 3) 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 7800 Carbon Filter 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
Carbon Filter and before the second ball valve. This makes it easy to rinse your new Carbon
Filter on start-up and gives you a place to test the water before it enters your household
plumbing.
4.
If you will be using copper piping, do not sweat the copper pipe directly on to the 7800 control
valve. Avoid heating up the 7800 control valve plastic with the torch.
5.
If have copper pipe before the Carbon Filter 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 Carbon Filter and then copper after it, if you have copper plumbing.
