7 . The system is now in the operational mode. You may start and run your system as you de-
sire. You will not have to go through the purging mode unless you “de-power” the system.
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 but-
ton to effect a fresh water flush cycle.
4. Press Auto Run Button
Note: 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. If you wish, you can
bypass the purge sequence and initiate a normal start. Pressing both “Auto Run” and
“Stop”
simultaneously anytime during the purge sequence will bypass the purge se-
quence and enable a normal start. In any case do not pressurize the system for the
first twenty minutes or more.
5. After the purge sequence. The control will alarm with the message “ Close Pressure Relief
Valve ” - Close the valve and proceed by pressing “Auto Run.”
6. 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 minutes
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.
8. 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 no bubbles anywhere in the intake hoses and the feed pump should sound
smooth after priming. If the feed pump continues to sound rough, find the reason before con-
tinuing! Inspect the system for leaks.
