Page 13: Construction And Operation
Construction and Operation Construction and Operation Items referred to in ( ) correspond with the items in the Pipe and Instrument Flow Diagram (see chapter 5.6). Construction The main component of the refrigerated dryer comprises a combined heat exchanger (heat transmitter). -
Page 14: Refrigerant Circulation
Construction and Operation Refrigerant Circulation The dryer is able to cool the compressed air by using a refrigeration system not unlike a typical home refrigerator. Cooling is achieved by transferring heat from the compressed air to the refrigerant by vaporizing (boiling) the refrigerant, thereby turning the refrigerant into a gas. -

Page 20: Compressed Air Connection
Installation Compressed Air Connection Attention! Use flexible connecting pipes at the compressed air inlet and dis- charge to ensure vibration isolation, prevent strain on piping connec- tions and allow easy installation. To avoid damage, do not overtighten the compressed air connections. The refrigerated dryer is piped ready for operation. -
Page 21: Condensate Drain Connection
Installation Condensate Drain Connection A hose connection is provided for drainage of the condensate. See chapter 1.5 for the di- mensions. Use larger cross---sections for condensate lines longer than 16ft. Attention! Take care when fitting the condensate drainage hose that the conden- sate separated by the refrigeration dryer can flow without hindrance. -

Adjustments may not be made to these compo- nents without prior written consultation with KAESER Compressors Inc. Points to be Observed before Switching On: NON -- OBSERVANCE OF THESE OR OTHER REFERENCES (WARNING;... -
Page 23: Ready For Operation
Initial Start Ready for Operation Attention! Do not start the refrigerated dryer until completing the following: The refrigerated dryer is installed according to the conditions stated in chapter 6. All electrical connections, air piping and condensate lines are correctly connected and properly tightened. -
Page 24: Operation
Operation Operation During operation of the refrigerated dryer, condensate is separated from the compressed air. The condensate must be drained and collected in a suitable container. It must be disposed of according to Federal and local environmental codes. Collect the accumulated condensate in a container and dispose of properly.

Page 25: Starting The Refrigerated Dryer
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 26: Stopping The Refrigerated Dryer
Operation If the control lamp (2) does not extinguish after approximately 15 min- utes then a fault is apparent (see chapter 8.4.3). Do not open the compressed air shut-- off devices (inlet/outlet) until Attention! the control lamp (2) is extinguished. Open the shut ---off valve of the compressed air inlet slowly (admission of the compressed air). -
