Page 11: General Description
Instruction book General description General description Introduction The air dryers described in this book are heatless adsorption dryers, designed to remove humidity from compressed air for industrial applications. There are different variants of the dryers, all equipped with a DC1 electronic controller. Depending on the variant, the dryer can reach a pressure dew point of -40 °C (-40 ˚F) or -70 °C (-100 ˚F). -

Page 29: Operating Instructions
Instruction book Operating instructions Danger: Check the connections of the dryer for air leaks. Air leaks could result in serious or potentially fatal conditions, such as hearing damage due to noise, harm to the skin due to pressurized air, and air embolism. Warning: The operator must read and understand all relevant safety precautions. - Page 30 Instruction book 8. Open the air supply towards the pressure dew point (PDP) sensor. Notice: Close the external inlet valve in case the compressor needs to be restarted. The high air speed in the startup phase of the compressor may damage the desiccant. During operation The LEDs for pressure dew point (PDP) warning and pressure dew point (PDP) alarm are only functional if the dryer is equipped with a pressure dew point (PDP) sensor.
