3. The system is now in the operational mode. You may start and run your system as you
desire. You will not have to go through the purging mode unless you “de-power” the sys-
tem. If you do, you can bypass the purging mode by pushing “Stop” and “Auto Run”
buttons at the same time. It is best to use the “Auto Run” button which defaults to the
automatic fresh water rinse. If you shut down the system from the “Stop” button then use
the “Auto Store” button to effect a fresh water flush cycle.
Note: You can bypass the purge sequence and initiate a normal start at any time by
Pressing both “Auto Run” and “Stop” simultaneously. This will bypass the
purge sequence and enable a normal start.
If you must stop the purge sequence for any reason, the control will default
back to the beginning of the purging mode to protect your system.
Do not bypass the purge mode unless you are sure that the chemicals are
purged from the system or you will permanently damage the membrane.
1. After the purge sequence, the control will alarm with the message “Close pressure relief
valve”. Close the valve and proceed by pressing “Auto Run.”
2. The system is now running under pressure and making water. The display will read
“purging product water.” This mode dumps the product water overboard for ten min-
utes in case there is any residual chemicals in the membrane. Carefully inspect for leaks
over the entire system! Shut down the system and repair any leaks you find.
4. Check that the system is operating within its normal parameters. Compare with the chart
on the next page.
The system will go into a start mode and the feed pump will start shortly after. The system
should prime within 60-90 seconds. Check the strainer and the brine discharge for water
flow. There should be few bubbles anywhere in the intake hoses and the feed pump should
sound smooth after priming. After confirming that the system is primed, inspect for leaks.
Note: The reject light will be on whenever the
product water is being rejected or not being made.
When the product water is below 750 PPM the
green (Good) light will show that water is going
to the tank.
