RINSE OPERATION 

The  rinse  pump  will  operate  whenever  the  rinse  power 
signal  is  applied  to  the  circuit  board,  whether  directly 
from  the  dishwasher,  or  by  using  a  pressure  switch.  A 
rinse delay  feature  and  rinse  limit  feature  maximize  the 
operating capabilities of the rinse pump. 

A prime button, located on the front cover, will allow the 
rinse  pump  to  run  at  full  speed,  regardless  of  the  rinse 
potentiometer  setting.  Main  power  must  be  applied  to 
the system to prime the pump, a signal is not necessary. 

RINSE SPEED SETTING 

(1)  Turn  the  rinse  potentiometer  clockwise  to  increase 

speed of the rinse pump 

(2)  Adjust  as  needed  to  achieve  the  best  sheeting 

action. 

RINSE DELAY SETTING 

This feature delays the operation of the rinse pump for a 
programmed  time  once  the  rinse  power  signal  is 
received.  This  function  is  typically  used  to  conserve 
rinse  agent  injection  on  door-type  dishwashers  (using 
with  conveyor  machines  is  not  recommended).  The 
rinse delay range is 0 - 14 seconds. 

(1)  Turn  the  rinse  delay  potentiometer  clockwise  to 

increase. 

(2)  Turning  the  setting  to  full  minimum  shuts  off  this 

feature. 

RINSE LIMIT SETTING 

This feature will stop the rinse pump after 30 seconds of 
continuous  operation,  conserving  rinse  agent  on 
dishmachines that fill through the rinse valve. 

Slide switch to “rinse limit” to activate.
