Important Warnings for R410A
- • POE oil is highly hygroscopic - keep sealed
- • Never mix with mineral oil
- • Use dedicated recovery equipment
Oil Return: High velocity in vertical risers required due to high operating pressure
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 R410A refrigerant.
2
Use POE oil only. Oil charge: 1050 cc.
3
Breaker size recommendation: 17 A minimum (based on RLA × 1.25).
4
Wire size should be rated for 13 A continuous load at 220-240V/50Hz.
