Important Warnings for R290
- • HIGHLY FLAMMABLE (A3) - explosion-proof equipment required
- • Both MO and POE compatible
- • Follow strict charge limits per IEC 60335-2-89
Oil Return: Excellent solubility with both oil types
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 R290 refrigerant.
2
Use POE oil only. Oil charge: 180 cc.
3
Breaker size recommendation: 4 A minimum (based on RLA × 1.25).
4
Wire size should be rated for 2.5 A continuous load at 115V.
