Technician's Tips
- When using A2L refrigerants (R455A/R454C), comply with the applicable safety/ventilation standards.
- Braze the brazed/ODF connections under nitrogen to prevent internal oxidation.
- POE oil absorbs moisture; evacuate the system thoroughly before commissioning.
- The stated capacity is at HBP conditions (te +7.2°C / tc +54.4°C); confirm for your own conditions with Danfoss Coolselector.
