Important Warnings for R407C
- • Zeotropic blend - expect 5-7°F glide
- • POE oil critical for R-407C compatibility
- • Not suitable for flooded evaporators
Oil Return: Adequate velocity important due to glide characteristics
General Oil Guidelines
!
Never mix MO (Mineral) and POE oils - causes chemical breakdown
💧
POE absorbs moisture - keep container sealed, minimize air exposure
✓
Check oil level through sight glass after 24 hours of operation
Installation Guidelines
1
Ensure the system is properly evacuated before charging with R407C refrigerant.
2
Use POE oil only. Oil charge: 2000 cc.
3
Breaker size recommendation: 24 A minimum (based on RLA × 1.25).
4
Wire size should be rated for 18.5 A continuous load at 380-400V/50Hz.
