Important Warnings for R32

  • • R-32 is mildly flammable (A2L) - avoid open flames
  • • POE oil absorbs moisture - minimize air exposure
  • • Lower viscosity preferred due to better miscibility

Oil Return: Good oil return characteristics due to excellent miscibility

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 R32 refrigerant.

2

Use POE oil only. Oil charge: 900 cc.

3

Breaker size recommendation: 25 A minimum (based on RLA × 1.25).

4

Wire size should be rated for 20 A continuous load at 220-240V/50Hz.
