1.>  Locate two 0-10Vdc Motor Control Boards in control panel

2.>  On intake Motor Control Board, observing "GREEN STATUS 

LIGHT", turn manual adjust potentiometer (with a small phillips-head 

screwdriver) "CCW" to increase "FLOW INDEX" or CW to reduce 

"FLOW INDEX" to match desired setting. 

(NOTE:  After long pause, 

the green status light will blink long-blinks for the "TEN COUNT" of 

the "FLOW RATE INDEX", which then is immediately followed by 
fast blinks which indicate the second digit.   For example, a Flow 

Index of 23 would be two long blinks, followed by 

three

 fast 

blinks of the "GREEN STATUS LIGHT".)
