The additional refrigerant charge amount recommended is a guideline for longer piping application.
The actual charge required may be different from the guideline due to different application and variation
in site conditions.
Diagram shows typical charging method:
Note : R22 - Nil
R-410A - Nil
Avoid prolong exposure of an opened compressor, or the internal part of refrigerant piping to moist
air. The POE oil in the compressor and piping can absorb moisture from air.
CAUTION FOR R-410A
