    Air cooled centrifuges: Ensure sufficient ventilation. The centrifuge 8K (B) with an air-cooled compressor should not be set up with its left side against a wall, since otherwise the hot air, which is emitted out the back, will be drawn in again as fresh air for cooling. As a result, the unit will switch off due to overheating (see also 7.2 "Error...

  • Page 24: Set-Up

    8K(B) Set-up and Connection 5.3.1 Set-up Transport the centrifuge as closely as possible to the installation site with a lifting device (e.g. forklift). Set the centrifuge down. To place the centrifuge on the castors, open the front door with the supplied square spanner (part no. 930 114) by turning it clockwise by 90°.

  • Page 25: Alignment

    8K(B) Set-up and Connection 5.3.2 Alignment For reasons of safety, the centrifuge must not be operated while it is set up on its castors! The centrifuge must be set-up stably and horizontally at the installation site. Set the centrifuge on its adjustable feet (see 5.3.1 in reverse order) To do so, turn all of the feet clockwise by hand until they touch the ground.

  • Page 26: Power Supply
