Page 13: Transport
Transport Transport Check the packaging for visible loss or damage. If no visible damage can be ascertained, place the unit in close proximity to the place of installation and unpack the device. During this procedure, the chiller must always remain in an upright position. The components may be damaged when the unit is tilted or turned upside down. -
Page 14: Installation
Installation Installation Place of installation Note! Ambient conditions! In the event that the chiller is not installed under suitable ambient conditions, the ability of the device to condense refrigerant gas is impaired. This can result in a higher load of the refrigerating compressor, and in a loss of efficiency and performance of the chiller. -
Page 15: Installation Plan
Installation Installation plan Air compressor Aftercooler Condensate separator Prefilter Bypass group Chiller Compressed-air tank Final filter BEKOMAT condensate drain Installation type A straight upstream of the application is recommended. Installation type B is NOT recommended because of the low compressed air temperature there will be condensation outside of the pipes and vessel and the air will be rewarmed. -

Page 19: Electrical Connections
Installation Electrical connections Danger! Supply voltage! The connection to the electric mains should only be carried out by qualified skilled personnel and must correspond to the legal provisions in force in your region. Prior to connecting the device, please check the name plate to avoid exceeding the indicated values. The voltage tolerance is +/- 10%. -
Page 20: Condensate Drain
Start-up Condensate drain Danger! Compressed air and condensate under pressure! The condensate is discharged at system pressure. The drain pipe needs to be secured. Never direct the condensate drain pipe at persons. The chiller is delivered with an already integrated electronically level-controlled BEKOMAT condensate drain. Connect the condensate drain with a collection system or container by properly screwing it on. -
Page 21: Initial Start-Up
Start-up Initial start-up Note! The chiller must not be started up more than six times an hour. Wait at least five minutes prior to every restart. The user is responsible for the compliance with these provisions. Irreparable damage can be caused by starting up the device too often. -
Page 22: Start-Up And Shut Down
Start-up Start-up and shut down During short-term shut down (max. two to three days), it is advisable to leave the chiller and the control panel connected to the supply current circuit. Otherwise, it would be necessary at a restart of the chiller to wait two hours, until the oil in the compressor has reached the specified operating temperature. -
