After the backwash, the system will automatically go into the fast rinse stage. Both stages
will last for as long as you have programmed that cycle step. The control valve will return to
service status (indicated by the up-flowing meter on the left) after the backwash and rinse
are complete.
Congratulations, you are done setting up your valve!
Maintenance:
Normal Operation
-Normal service display alternates between service days, time of day and scheduled
rinsing time.
-Days remaining until the next service will count down from the day value to 1 day
remaining.
-Once the count reaches 1, a service cycle will be initiated at the next designated rinsing
time.
Troubleshooting the 7500 Carbon Filter:
Backwash Flow Rate
One problem that may occur is if you do not have enough backwash flow rate to properly clean
the Carbon filter. You can verify the backwash flow rate by running the drain line into a bucket
and timing it when the 7500 is in Cycle 1 or backwash. A 1.0 or 1.5 cubic foot system should
have 5 gallons per minute and a 2.5 cubic foot system should have 10 gallons per minute of
backwash.
