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.
● System's normal high pressure value is within
20~25º C(68~77° F) According to the change in
ambient temp and system operational capacity,
system's high pressure value is 10~40
º C(50~104° F) higher than ambient temp The higher
ambient temp is, the smaller temp difference is.
º C(° F)
● When ambient temp is 25~35ºC(77~95°F),
system's high pressure value in cooling mode is
44~53º C(111.2~127.4° F).
● When ambient temp is -5~10º C(23~50° F),
system's high pres sure value in heating mode is
40~52º C(104~125.6° F).
● When ambient temp is 25~35ºC(77~95°F),
system's low pressure value in cooling mode is
0~8º C(32~46.4° F).
º C(° F)
● When ambient temp is -5~10º C(23~50° F),
system's low pressure value in heating mode is
-15~5º C(5~41° F).
● In cooling mode, heating electronic expansion
valve remains 480PLS.
● In heating mode, the opening angle of adjustable
PLS
electronic expansion valve varies within
120~480PLS.
