1.1.4.1.2 When running in dehumidify mode, the outdoor ambient temperature restricts frequency as follows:
(only applying to the machine models with outdoor ambient temperature sensor).

1.1.5 Defrosting running
1.1.5.1 Defrosting process
When defrosting during heating operation, frequency is not controlled according to the temperature difference, and
the maximum heating frequency is displayed.
Compressor does not stop in the process of defrosting.
Defrosting beginning conditions: Heat mode, the first power on operation or the lasting time to the previous
defrosting finishing is more than 47 minutes, and the outdoor ambient temperature is continuously found to be less
than -4ｏC ( model: 09) or -5ｏC (12) during compressor running, and then defrosting starts.
Defrosting process as following illustration:
Outdoor fan Defrosting process
4-way valve Defrosting process 55S
Compressor 55S 5S Defrosting process 60S
Defrosting finish compressor restart
1.1.5.2 Air volume control during defrosting
20 seconds Low wind is firstly selected during defrosting, then indoor fan stops running.
1.1.6 Special function
1.1.6.1 Trial running
1.1.6.1.1 Beginning conditions
Pressing emergency button 5-10 seconds and buzzer sounding twice, then starts.
1.1.6.1.2 Running status
When in trial running, the display frequency of compressor is 58Hz, running mode is cool, compressor keeps on
