If the system has been pickled or stored, use the “New System Startup” procedure. 
 
1.  Check to see that the inlet seacock is open. 
2.  Push the “Auto Run”  one or more times.  The machine will run for one hour for each 

time the button is pushed, then shut off and automatically do a fresh water flush.   If you 
receive a “System Stalled” error code, there is no flow in the system. Open the pressure 
relief valve on the Clark Pump and bleed the air out of the feed pump.  

3.  Run the system until you have filled your tank or have made enough to meet your re-

quirements for several days.   

4.  When the unit shuts down it will enter the “Auto Store” mode, which will flush the unit 

every five days unless you run it to make water,  the unit is de-powered, or the “Stop” 
button is pressed. 

5.  You may stop the system at any time with the “Stop” button, but if you do it will not 

flush itself or go into “Auto Flush” mode. 

 
You may now leave the system unattended for up to five days without further attention 
We recommend operating the system for longer periods and effecting a fresh water flush 
rather than running the machine every day and not flushing the system. Remember that you 
need to run the system almost a half hour to make the flushing water. You may notice that 
the system output is higher while charging your batteries  as the machine is voltage sensitive. 

Warning! Understanding automatic fresh water flush system is essential for it to be effec-
tive. 
1.  Make sure that the system has continuous power. Shutting down power will reset control. 
2.  Make sure that the potable water system is “on” and that there is adequate water in the 

tank for the extended period.
