- Page 8 When operating in the vacuum range, there is a danger of air en- tering 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 | AQ450641889580en-000402 © Danfoss | Climate Solutions | 2025.04...

- Page 12 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). 12 | AQ450641889580en-000402 © Danfoss | Climate Solutions | 2025.04...
- Page 13 If the refrigerant needs topping up after starting the compressor, it can be topped up in vapour form on the suction side, or, taking suitable precautions, also in liquid form at the inlet to the evaporator. AQ450641889580en-000402 | 13 © Danfoss | Climate Solutions | 2025.04...
- Page 14 Heavy shocks and vibrations to the shaft as well as continuous cyclic operation are to be avoided. The sealing surfaces can stick together during prolonged downtimes (e.g. winter). Therefore, run the system every 4 weeks for 10 minutes. 14 | AQ450641889580en-000402 © Danfoss | Climate Solutions | 2025.04...
- Page 15 • Initial oil change during the rst maintenance of the vehicle (at the latest after one year) • Then after every 5,000 operating hours, at the latest however after 3 years. Also clean the oil lter. • An oil change is also necessary, if the oil is very cloudy and dark, or after repairs have been carried out on the compressor.

- Page 16 • Frequent cycling • Long periods of stoppage • Material deposits / dirt from the system Due to these effects, the shaft seal can develop leaks, and it must then be replaced. 16 | AQ450641889580en-000402 © Danfoss | Climate Solutions | 2025.04...
- Page 17 When the compressor is depres- surised, undo the fastening screws of the shut-off valves. Remove the compressor using an appropri- ate hoist.
