System Start-up
Prior to start-up
1. Check all connections to be sure they are secure.
2. Turn on feed water valve and check for leaks. (Turn off
and correct leaks if leaks occur.)
3. Close product water valve and wait five minutes and let
the systems pressurize to see if leaks result.
4. If there are no leaks, leave the product valve closed and
proceed to System Flush.
System Flush and Operation Check
To make sure RO/DI system is operating correctly, follow
these simple procedures:
1. Open the product water valve and allow the system to run
until there is no air in the water stream.
2. Close product water valve and re-fill the system.
3. Allow system to process water until the tank is full or the
system is pressurized. Check for leaks and confirm that
the water going to the drain has stopped.
NOTE: The system is “OFF” when the drain water stops.
4. Open the product water valve again and allow tank or
system to empty for a second time.
Do not use this water
.
5. Close the product valve and allow the tank or system to re
-fill. Check the water quality using a TDS meter,
conductivity meter or resistivity meter. When the system is
producing the quality needed, it is flushed and ready for
operation. A RO/DI system that is working properly, will
typically produce water at “0” ppm of TDS or lower.
