4.3 Rectification factor for heating defrosting
When outdoor environment has satisfied certain condition (temperature and humidity), frosting and
defrosting might occur, at this time, heating capacity of the unit will be attenuated, therefore, when
calculating heating load model selection, please add defrosting rectification factor.
Defrosting rectification factor is as follow:

5.1 Outdoor Unit Noise Curve
Test method for noise
:
Test environment: Semi-anechoic room, the noise will be a little bit higher in actual operation due to
environmental change.
Noise curve test point is as follow:
GMV-224WM/G-X GMV-280WM/G-X
