Operating Instructions
1. AUTO MODE : In this mode, operation
mode(COOL, HEAT) is selected automati-
cally by the room temperature of initial
operation.
∆T= -1°C, -2°C, 0°C, +1°C, +2°C
∆T is controlled by setting temperature
up/down key of remote control
2. COOL MODE : The unit operates accord-
ing to the difference between the setting
and room temperature. (18°C~30°C)
3. HEAT MODE : The unit operates accord-
ing to the difference between the setting
and room temperature.(16°C~30°C)
*Prevention against cold wind : In order to
prevent the cool air from flowing out at
the heat mode, the indoor fan does not
operate or operates very slowly in the
following cases. At this time, the indoor
heat exchanger will be preheating.
- For 3~5 minutes after the initial
operation
- For deicing operation
- The operation of an indoor fan in
accordance with the temperature of an
indoor heat exchanger
*High temperature release function : It is a
function to detect an outdoor overload by
the sensor of an indoor heat exchanger
and to turn the outdoor fan or the
compressor ON/OFF for safety.
*Deice : Deicing operation is controlled
by indoor unit's heat exchanger tempera-
ture and accumulating time of compres-
sor's operation.
Deice ends by sensing of the processing
time by deice condition.
4. DRY MODE : Has 3 states, each deter-
mined by room temperature.
The unit operates in DRY mode.
*Compressor ON/OFF Time is controlled
compulsorily(can not set up the fan
speed, always breeze).
*Protective function : Low temperature
release. (Prevention against freeze)
5. TURBO MODE : This mode is available in
AUTO, COOL, HEAT, DRY, FAN MODE.
When this button is pressed at first, the
air conditioner is operated “powerful”
state for 30 minutes regardless of the set
temperature, room temperature.
When this button is pressed again, or
when the operating time is 30 minutes,
turbo operation mode is canceled and
returned to the previous mode.
*But, if you press the TURBO button in
DRY or FAN mode that is changed with
AUTO mode automatically.
6. SLEEP MODE : Sleep mode is available
only in COOL or HEAT mode.
The operation will stop after 6 hours.
*In COOL mode : The setting temperature
is automatically raised by 1°C each 1hour
When the temperature has been raised by
total of 2°C, that temperature is main-
tained.
*In HEAT mode : The setting temperature
is automatically dropped by 1°C each
1hour.
When the temperature has been dropped
by total of 2°C, that temperature is main-
tained.

8. COMPULSORY OPERATION :
For operating the air conditioner without
the remote control.
*The air conditioner starts up in the most
suitable mode for the room temperature:
9. SWING : BLADE-H is rotated vertically by
