Flushing the System
The system should be flushed weekly to remove sediment from the surface of the membranes. To manually flush the system, follow the steps below:
The system must be operating during the flush procedure.
Fully open the concentrate valve.
Allow the system to run for 10 to 20 minutes.
After 10 to 20 minutes, close the concentrate valve to its previous setting. Ensure the proper concentrate flow rate is going to the drain.
The system is now ready to operate.
