  • Page 8: Areas Of Application

    W hen operating in the vacuum range, there is a danger of air e ntering on the suction side. This can cause chemical reactions, a pressure rise in the condenser and an elevated compressed-gas temperature. Prevent the ingress of air at all costs! 8 | AQ452034894212en-000201 © Danfoss | Climate Solutions | 2023.06...

    Evacuate the suction and discharge pressure sides using the vacuum pump. At the end of the evacuation process, the vacuum should be < 1.5 mbar when the pump is switched off. Repeat this process as often as is required. AQ452034894212en-000201 | 23 © Danfoss | Climate Solutions | 2023.06...

  • Page 24: Refrigerant Charge

    Suction gas superheating at the compressor input should be min. 7 - 10 K (check the setting of the expansion valve). The system must reach a state of equilibrium. P articularly in critical systems (e.g. several evaporator points), measures such as the use of liquid traps, solenoid valve in the liquid line, etc. are recommended. There should be no movement of refrigerant in the compressor while the system is at a standstill. 24 | AQ452034894212en-000201 © Danfoss | Climate Solutions | 2023.06...
