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 R134a refrigerant.
2
Use POE oil only. Oil charge: 1550 cc.
3
Breaker size recommendation: 25 A minimum (based on RLA × 1.25).
4
Wire size should be rated for 19.8 A continuous load at 380-420V/50Hz.
