    Operation Explanation of the colored segment scale of the pressure dew point indication: (suction pressure gauge) Blue -- white range (low suction pressure) results in too low a pressure dewpoint due --- Evaporator temperature too low (evaporator freeze---up) --- Dryer too large or very low air demand. Refer to chapter 1.4 Green range (normal suction pressure) results in a normal pressure dew point.
  • Page 25: Stopping The Refrigerated Dryer

    Operation  Open the shut ---off valve of the compressed air inlet slowly (admission of the compressed air).  Open the shut ---off valve of the compressed air outlet slowly. The compressed air system is now connected to the refrigerated dryer. * If the control lamp (3) does not illuminate, possibly one of the two fuses is defective.
