  • 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.
