Connect some flexible tubing from the drain connection on the 7800 control valve to a suitable
drain such as a septic tank or drain to a sewer. It is OK to run the drain line up and over the
7800 Carbon 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.

Plug your 7800 control valve into an outlet. After being plugged in, the screen may display
“WAITING PLEASE” while it finds the service position. By default, the control valve will be set to
work like a Water Softener, but that’s not correct for this application. So, next you will need to
program the system to work as a Carbon Filter. There are a few settings that must be changed
before the system can be put into service.
