Compressor 
working current 
GMV-H224WL/A-X 
GMV-224WL/C-X 
When compressor works 
normally, the current is no 
more than 18.0A. 
GMV-H280WL/A-X 
GMV-280WL/C-X 
When compressor works 
normally, the current is no 
more than 23.0A. 
GMV-H335WL/A-X 
GMV-335WL/C-X 
When compressor works 
normally, the current is no 
more than 25.0A. 
When ambient temperature is below 35℃, IPM 
temperature is lower than 70℃. Maximum 
temperature is 80℃. 
Indoor heat 
exchanger’s inlet 
temp 
●According  to  ambient  temp,  for  a  same  IDU  in 
cool  mode,  the  inlet  temp  will  be  1℃~7℃  lower 
than  the  outlet  temp,  and 4~9℃  higher  than  the 
low pressure value. 
●For a same IDU in heat mode, the inlet temp will 
be 10℃~20℃ lower than the outlet temp. 
Indoor heat 
exchanger’s inlet 
temp 
Opening angle of 
indoor EXV 
●In cool mode, the  opening angle of indoor EXV 
varies within 40~480PLS. 
●In heat mode, the opening angle of indoor EXV 
varies within 70~480PLS. 
Number of IDUs detected by software is the same 
with the actual number. No communication error. 
Indoor  unit  can  drain  water  out  completely  and 
smoothly.  Condensate  pipe  has  no  backward 
slope  of  water;  Water  of  outdoor  unit  can  be 
drained  completely  through  drainage  pipe.  No 
water drop from unit base. 
Compressor and indoor/outdoor fan motor do not 
have strange noise. Unit can operate normally.
