As well as professions with comparable training that enables personnel to assemble, install, maintain and repair refrigeration and air-conditioning systems. Personnel must be capable of assessing the work to be carried out and recognizing any potential dangers. AQ450438640296en-US0301 | 5 © Danfoss | Climate Solutions | 2024.04... -

Page 8: Areas Of Application
When operating in the vacuum range, there is a danger of air entering 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 | AQ450438640296en-US0301 © Danfoss | Climate Solutions | 2024.04... -
Page 9: Compressor Assembly
Setup on an even surface or frame with sufficient load- bearing capacity. Single compressor preferably on vibration damper. Duplex and parallel circuits always rigid. Installation of pipe vibration mufflers is recommended! AQ450438640296en-US0301 | 9 © Danfoss | Climate Solutions | 2024.04... -
Page 10: Pipe Connections
As soon as the motor and the compressor reach their rated speed, the solenoid valve closes and the non-return valve opens (Fig. 6). The compressor now works under normal load.

Page 12: Operating The Shut-Off Valves
—> Service connection opened / shut-off valve opened. After activating the spindle, generally fit the spindle protection cap again and tighten with 14-16 Nm (10-12 lb-ft). This serves as a second sealing feature during operation. 12 | AQ450438640296en-US0301 © Danfoss | Climate Solutions | 2024.04... -
Page 13: Suction Pipe Filter And Filter Drier
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.

Page 14: Standard Motor, Design For Direct Or Partial Winding Start
This winding division reduces the start-up current needed for a part winding start to approx. 50% of that for a direct start. A mechanical unloaded start with bypass solenoid valve is not required. 14 | AQ450438640296en-US0301 © Danfoss | Climate Solutions | 2024.04... - Page 15 After the motor starts up via partial winding 1, partial winding 2 must be switched on after a maximum delay of one second. Failure to comply can adversely affect the service life of the motor. AQ450438640296en-US0301 | 15 © Danfoss | Climate Solutions | 2024.04...
