Single compressor preferably on vibration damper. Duplex and parallel circuits always rigid. Sun protection: If the compressor is set up outdoors, it has to be protected from direct sunlight. 10 | AQ450440081306en-US0201 © Danfoss | Climate Solutions | 2023.07... -
Page 11: Pipe Connections
Improperly installed pipes can cause cracks and tears, the result being a loss of refrigerant. Proper layout of the suction and discharge lines directly after the compressor is integral to the system’s smooth running and vibration behavior.

Page 12: Operating The Shut-Off Valves
Before opening or closing the shut-off valve, release the valve spindle seal by approx. ¼ of a turn counter-clockwise. After activating the shut-off valve, re-tighten the adjustable valve spindle seal clockwise.
