Step 18: if there's no error during operation for about 40min, system will automatically confirm
that debugging is finished and then stop. System resumes standby condition and displays as below:

Step 19: after debugging is finished, some functions can be set up according to project's actual
needs. For specific details, please refer to System Functions Setup. If no special requirements, skip
this step.
Step 20: deliver the product to user and inform user about usage precautions.

º C(° F)
● When system compressor starts up, temp of
º C(° F)
discharge tube or casing top in cooling mode is
within 70~95º C (158~203° F), and at least 10
º C(° F)
º C(50° F) higher than system high pressure
saturation temp; Temp in heating mode is within
65~80º C(149~176° F), and at least 10º C(50° F)
º C(° F)
higher than system high pressure saturation temp.
● When inverter compressor starts but inverter
compressor 2 stops, the discharge tube temperature
º C(° F)
of inverter compressor 2 is almost the same with
ambient temp.
● In cooling mode, defrost temp1 is 5~11ºC
(41~51.8° F) lower than system high pressure value;
º C(° F)
● In heating mode, defrost temp1 is about 2ºC
(35.6° F) different from system low pressure value.
