Technician Recommendations

• CAUTION — Voltage: This 3VI variant has a 200-230V / 3 phase / 60 Hz motor; do not operate it on a 400V network. For 380-415V/400V, choose the 4VI variant (MTZ72HN4CVE).
• Use the ODF sleeves supplied with the product on the rotalock service valves and braze the connections under nitrogen to prevent internal oxidation.
• POE oil absorbs moisture; keep the compressor sealed until the moment of installation and evacuate the system thoroughly before commissioning (moisture = acid + winding failure).
• Verify the phase sequence and direction of rotation at first start-up; do not allow more than 12 starts per hour.
• The stated capacity is based on te +5°C / tc +50°C (50Hz); confirm the actual capacity for 60Hz and your own evaporating/condensing temperatures with Danfoss Coolselector.
