Important Warnings for R22
- • R-22 is being phased out - consider system upgrade
- • AB (Alkylbenzene) oil also compatible
- • Never mix with POE oil
Oil Return: Good miscibility with mineral oil at normal operating temps
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 R22 refrigerant.
2
Use Mineral oil only. Oil charge: 420 cc.
3
Breaker size recommendation: 8 A minimum (based on RLA × 1.25).
4
Wire size should be rated for 6.2 A continuous load at 220-240V/50Hz.
