Page 8: Areas Of Application
For operation with frequency converter: - The maximum current and power consumption must not be exceeded. In the case of operation above the mains frequency, the application limit can therefore be limited. (For more on the subject of frequency converters, see chapter 5.8, p. 18) 8 | AQ451923867809en-000301 © Danfoss | Climate Solutions | 2024.07... - Page 9 Prevent the ingress of air at all costs!

Superheating can damage the valve. Remove the pipe supports therefore from the valve for soldering and accordingly cool the valve body during and after soldering. Only solder using inert gas to inhibit oxidation products (scale). 10 | AQ451923867809en-000301 © Danfoss | Climate Solutions | 2024.07... -
Page 11: Pipes
A rule of thumb: Always lay the first pipe section starting from the shut-off valve downwards and parallel to the drive shaft. Rigid As short as fixed point possible Fig. 6 AQ451923867809en-000301 | 11 © Danfoss | Climate Solutions | 2024.07... -
Page 12: Operating The Shut-Off Valves
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. 12 | AQ451923867809en-000301 © Danfoss | Climate Solutions | 2024.07... -

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. AQ451923867809en-000301 | 19 © Danfoss | Climate Solutions | 2024.07... -

Only then may the speed of the compressor be reduced. Check the oil level by: The oil must be visible in the sightglass. ATTENTION I f larger quantities of oil have to be topped up, there is a risk of oil hammer effects. If this is the case check the oil return! 20 | AQ451923867809en-000301 © Danfoss | Climate Solutions | 2024.07... -

Close the shut-off valves on the compressor. Drain the refrigerant (it must not be discharged into the environment) and dispose of it according to the regulations. When the compressor is depressurised, undo the fastening screws of the shut-off valves. Remove the compressor using an appropriate hoist. Dispose of the oil inside in accordance with the applicable national regulations. AQ451923867809en-000301 | 23 © Danfoss | Climate Solutions | 2024.07... -
