Outdoor Unit
To protect the compressor from reverse
rotation when power off suddenly.
The 2-step Overload Protector is to protect
the compressor when
1/ temperature of compressor reaches 120 C
2/ high temperature or current enters into the
compressor.

Time Delay Safety Control
Automatic Restarting Control
Anti-freezing Control
• ••
• If temperature of evaporator is lower than 2°C continuously
for 4 minutes, the compressor will cease to prevent the
evaporator from freezing. Fan speed setting will not be
changed.
• ••
• When temperature of evaporator reaches 10°C,
compressor will restart.
During Cooling Mode Operation, the Time Delay Safety Control
is available.
Anti-reversing Control
7 Operation Details
7.1. Cooling Mode Operation
• ••
• When selecting the Cooling Mode Operation, the unit will operate according to the setting by the Remote Control and the
operation is as the following.
• ••
• 3 min. ---- The compressor is ceased for 3 minutes to balance the pressure in the refrigeration cycle.
• ••
• (Protection of compressor).
• ••
• 7 min. ---- The unit will automatically operate in 7 minutes even if the room temperature is not reached.
(Prevention of raising the humidity)
• ••
• If the compressor has been continuously running for 5 minutes, and the difference of temperature between intake air and
evaporator is continuously lower than 2.5°C for 2 minutes, the compressor is ceased for 3 minutes then restarts. (Time Delay
Protection Control is effective.)

Automatic Fan Speed Mode
Time Graph for cooling Operation
During Cooling Mode Operation, use remote control to select Automatic Fan Speed.
• ••
• Fan speed will be at the point between "high speed" and "medium speed".
• ••
• Deodorization control.

7.2. Soft Dry Mode Operation
• ••
• When selecting Soft Dry mode operation, the operation will be cooling until the room temperature reaches the set temp on the
remote control, and then Soft Dry will be activated. (During Soft Dry Mode the fan of indoor unit will operate at super low speed.)
• ••
• Once soft Dry mode operation is turned off, indoor fan, compressor and outdoor fan will stop for 6 minutes.
• ••
• During cooling mode operation, if the compressor ceased, it will not restart within 3 minutes.
• ••
• Same as the denotation in Cooling Operation. (P.15)
(During Soft Dry Mode Operation, compressor will stop for at least 6 min.)
• ••
• Same as the denotation in Cooling Operation. (P.15)
During Soft Dry Operation, use remote control to select Auto Fan Speed mode.
• ••
• Indoor Fan Speed is at super low.
• ••
• Deodorization control.

Standard for determining operation mode
7.3. Automatic Mode Operation
First Determination:
Second Determination:
One hour after the above determination, the unit will operate according to the table below.
1. Indoor fan operates at super low speed for 20 seconds.
2. After judging indoor air temperature, the operation is determined and operation continued at the mode determined.
3. After the operation mode has been determined, the mode does not change. However, Soft Dry mode operation includes cooling
mode operation.
4. If automatic mode operation is started while the unit is operating, operation will continue.
If current operation is in cooling mode (including the cooling mode operation when is a part of Soft Dry mode operation) it will
be maintained, and if current operation is not cooling mode, the appropriate operation mode is determined for 20 seconds at
super slow fan speed. Then the selected mode will continue.
5. Room temperature adjustment

Time graph for Air Circulation Mode Operation
7.4. Air Circulation Mode Operation
1. An additional heater may make the warm air evenly covering each corner of the room.
2. When the temperature near the ceiling reaches the setting temperature, Air Circulation Mode Operation commences at low
airflow volume. It stops when the temperature drops to 2°C below the setting temperature.
3. The vertical airflow direction louver will not swing.
7.5. Indoor Fan Motor Control
• ••
• Automatic fan speed control
When automatic fan speed set,the available range for fan speed is from H to SLo
• ••
• Manual Fan Speed Control
• ••
• Basic fan speed can be manually adjusted (Lo, Med,Hi) by using the fan speed selection button.
