Max. permissible operating LP = Low pressure : 100/150 bar pressure (LP/HP) HP = High pressure AQ452526009526en-000401| 9 © Danfoss | Climate Solutions | 2023.12...
  • Page 10: Compressor Assembly

    Do not use in a corrosive, dusty, damp atmosphere or a com- bustible environment. Setup on an even surface or frame with sufficient load-bearing capacity. Single compressor preferably on vibration damper. Compound connection basically rigid. 10 | AQ452526009526en-000401 © Danfoss | Climate Solutions | 2023.12...
  • Page 11: Connecting The Pipelines - Solder System

    After assembly, it is necessary to check the collar. The gasket must not be damaged. At least 80 % of the cutting face has to be covered. After check-up, screw on and tighten again as described above. AQ452526009526en-000401| 11 © Danfoss | Climate Solutions | 2023.12...

    Before opening or closing the shut-off valve, release the valve spindle seal by approx. of a turn counter-clockwise. After activating the shut-off valve, re-tighten the adjustable valve spindle seal clockwise.

  • Page 14: Operating Mode Of The Lockable Service Connections

    For systems with long pipes and higher degree of contamination, a filter on the suction-side is recommended. The filter has to be be renewed depending on the degree of contamina- tion (reduced pressure loss). 14 | AQ452526009526en-000401 © Danfoss | Climate Solutions | 2023.12...

  • Page 19: Oil Sump Heater

    For start-up and low speed operation, a voltage boost of 10-20V is recommended to slightly reduce the motor current and compensate for voltage drops through the compressor supply line (and filtering devices, if present). AQ452526009526en-000401| 19 © Danfoss | Climate Solutions | 2023.12...
