Attention :  

 

Before  switching  the  unit  on,  make  sure  that  all 

 

tubing  is  tightly  secured  and  the  flow  meter  is 

 

mounted  in  the  right  direction  of  the  cooling  water 

 

stream (see arrow).   

 
 

After verification of all electrical connections, switch 

 

the coolant monitor on (5). The green light within the 

 

main power switch is now illuminated. 

 
 

Open  then  the  water  tap  and  adjust  the  water  flow 

 

to the desired flow value shown on the lower line of 

 

the  display  (1).  During  50  seconds  after  the  initial 

 

start-up  (or  after  having  pressed  the  RESET-key 

 

(6) ), AQUASTOP® II is re-initialized and all alarms 

 

are inhibited. This gives you enough time to fill and 

 

adjust the entire installation. 

 
 

During  this  period,  a  circling  digit  on  the  display 

 

shows  the  initialisation  phase.  Occasional  alarms 

 

are  only  indicated  by  flashing  of  the  corresponding 

 

LED (4), but do not influence the connected heating 

 

and/or solenoid valve.
