Page 8: Areas Of Application
- The potential control range of the compressor is 25-70 Hz. - Max. permissible current consumption must not be exceeded. At max. rotation speed therefore, the application limit can be reduced. - Use a thermal protection thermostat. - Do not operate an additional capacity controller. - O il return at low frequency must be guaranteed. 8 | AQ464037893946en-IN0201 © Danfoss | Climate Solutions | 2024.07... - Page 9 Prevent the ingress of air at all costs!

Page 13: 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 contamination (reduced pressure loss). Moisture in the refrigeration circuit can lead to crystal and hydrate formation. For this reason, we recommend using a filter drier and a sight glass with a moisture indicator. AQ464037893946en-IN0201 | 13 © Danfoss | Climate Solutions | 2024.07... -

For motor protection use a current-dependent and time-delayed overload protection device for moni- toring all three phases. Set the overload protection device so that it must be actuated within 2 hours, if there is 1.2 times the max. working current. 14 | AQ464037893946en-IN0201 © Danfoss | Climate Solutions | 2024.07... - Page 15 230 V ∆ 400 V Y Direct start Star-delta start Direct start only L1 L2 L1 L2 L1 L2 L1 L2 INFO!

Evacuate the suction and high 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 the process as often as is required. AQ464037893946en-IN0201 | 21 © Danfoss | Climate Solutions | 2024.07... -
Page 22: Refrigerant Charge
Suction gas superheat 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. Particularly in critical systems (e.g. several evaporator points), measures are recommended such as replacement of liquid traps, solenoid valve in the liquid line, etc. There should be no movement of refrigerant in the compressor while the system is at a standstill. 22 | AQ464037893946en-IN0201 © Danfoss | Climate Solutions | 2024.07... -
