Important Warnings for R407C

  • • Zeotropic blend - expect 5-7°F glide
  • • POE oil critical for R-407C compatibility
  • • Not suitable for flooded evaporators

Oil Return: Adequate velocity important due to glide characteristics

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 R407C refrigerant.

2

Use POE oil only. Oil charge: 530 cc.

3

Breaker size recommendation: 10 A minimum (based on RLA × 1.25).

4

Wire size should be rated for 7.9 A continuous load at 208-230V/60Hz.
