How to Set the Backwash Time

How to Set the Backwash Time. For All Model #s Ending in 7000 or -7:

This is a brief overview of the 7000 valve. The button on the far left is the recycle button. The second button to the left is the up arrow, and the button on the right is the down arrow. To change the time your system backwashes, press and hold the up and down arrow buttons until the display changes. When the display changes to "DO", push the recycle button. You will now see "RT" which stands for regeneration time. Factory default setting on all EWS and CWL whole home filtration is midnight. You can change this time to any time in the day or night that is convenient for you. You can change it one minute at a time, or if you hold down one of the arrow buttons you can skip forward or backward faster to the time you desire, as demonstrated here. Here we are changing the time to 4:30am. 4:30am is now the time your filtration appliance will backwash. An afternoon or evening time will have a "pm" indicator on the top right. When you're all done simply push the recycle button.
