Technician Tips

• Braze the solder/ODF connections under nitrogen to prevent internal oxidation.
• POE oil is hygroscopic; keep the compressor sealed until installation and evacuate the system thoroughly before commissioning (moisture = acid + winding failure).
• Scroll direction of rotation is critical; verify the phase sequence at first start-up (in reverse rotation no pressure builds up and noise increases).
• The stated capacity is at HBP (te +7.2°C / tc +54.4°C) conditions; confirm the actual capacity for your own evaporating/condensing temperatures with Danfoss Coolselector.
