Important Warnings for R404A
- • High GWP refrigerant - being phased down
- • POE oil highly hygroscopic
- • Higher viscosity for low-temp applications
Oil Return: Low-temp systems need proper oil separator and suction line sizing
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 R404A refrigerant.
2
Use BSE32 oil only. Oil charge: 1900 cc.
3
Breaker size recommendation: 13 A minimum (based on RLA × 1.25).
4
Wire size should be rated for 10 A continuous load at 380-420V/3/50Hz.
