temp is, the smaller temp difference is. If
ambient temp is 25~35 ℃ in cool mode,
system’s high pressure value will be within
44~53℃.
●In heat mode, if ambient temp is above -5℃,
system’s high pressure value is within 40~52℃.
If ambient temp is low and many IDUs are
turned on, the high pressure will be lower.

●When ambient temp in cool mode is 25~35℃,
the low pressure value is 0~8℃.
●When ambient temp in heat mode is above
-5℃, the low pressure value is -15~8℃.

●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.

not have strange noise. Unit can operate
normally.
6 Common Malfunctions and Troubleshooting
Warning:
① If there is abnormal condition (e.g. unpleasant smell), turn unit off and disconnect power
immediately. Then contact Gree authorized service center. If unit continues operation
despite the abnormal condition, it may get damaged and lead to electric shock or fire
hazard.
② Do not repair the air conditioner by yourself. Improper maintenance may lead electric
shock or fire hazard. Please contact Gree authorized service center for maintenance.
