Cooling

 

Upon completion of firing the KCR32C lights all lamps on the mimic display and the 

kiln is allowed to cool naturally.

 

While the kiln temperature is above 40°C the display alternates every 5 seconds be-

tween the kiln temperature and HOt.

 

When the kiln has cooled to less than 40°C the display alternates every 5 seconds 

between the kiln temperature and End.

 

To return the KCR32C back to idle condition ready for the next firing press the ►  
key (or turn off the power to the instrument

).
