Note: You can bypass the purge sequence and initiate a normal start at any time by Pressing
“Auto Run” and “Stop” simultaneously. This will bypass the purge sequence and ena-
ble 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. Be
sure to purge the system of chemicals for at least twenty minutes. DO NOT BYPASS
THE PURGE MODE UNLESS YOU ARE ABSOLUTELY SURE THAT THE CHEMICALS ARE
PURGED FROM THE SYSTEM, OR YOU WILL PERMANENTLY DAMAGE THE MEM-
BRANE.
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. If the system has been pre-
served with propylene glycol, flip the toggle switch to RUN MANUAL and run the system
with the PRESSURE RELIEF VALVE OPEN for 4-6 hours to purge the propylene glycol (see
pages 44-45).
2. The system is now running under pressure and making water. The display will read
“PURGING PRODUCT WATER,” and count down another ten minutes while it purges any re-
sidual chemicals from the membrane and product lines. After ten minutes, if product water
is below 750 PPM it will send the product water to the tank. Carefully inspect for leaks over
the entire system. Shut down the system and repair any leaks you find.
3. The system is now operational, and you may run your system as you desire. When beginning
to make water it is best to use the Auto Run button which defaults to the automatic fresh
water flush after the unit is finished making water. If you shut down the system by pressing
the Stop button the system will not fresh water flush. If you do stop the system using the
Stop button, use the Auto Store button to effect a fresh water flush. You should fresh wa-
ter flush your watermaker after every use.
4. Check that the system is operating within its normal parameters. Compare with the parame-
ters on the next page.
The system will go into a starting mode and the feed pump will start shortly thereafter. The
fresh water flush solenoid will open, allowing water from your pressurized fresh water system
to help prime the pump. The system should prime within 30-90 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 sys-
tem 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.
