1. Warning: Prior to repair, disconnect the
power cord from the circuit breaker.
2. Use proper parts: Use only exact replacement
parts. (Also, we recommend replacing parts
rather than repairing them.)
3. Use the proper tools: Use the proper tools
and test equipment, and know how to use
them. Using defective tools or test equipment
may cause problems later-intermittent contact,
for example.
4. Power Cord: Prior to repair, check the power
cord and replace it if necessary.
5. Avoid using an extension cord, and avoid tap-
ping into a power cord. This practice may
result in malfunction or fire.
6. After completing repairs and reassembly,
check the insulation resistance. Procedure:
Prior to applying power, measure the resis-
tance between the power cord and the ground
terminal. The resistance must be greater than
30 megohms.
7. Make sure that the grounds are adequate.
8. Make sure that the installation conditions are
satisfactory. Relocate the unit if necessary.
9. Keep children away from the unit while it is
being repaired.
10. Be sure to clean the unit and its surrounding
area.

Operating Instructions and Installation
1. AUTO MODE : In this mode, operation
COOL mode is selected automatically by the
room temperature of initial operation.
∆T= -1°, -2°C, 0°C+1°C+2°C
∆T is controlled by setting temperature
up/down key of remote controller
* FAN SPEED : AUTO
2. COOL MODE : The unit operates according
to the difference between the setting and
room temperature. (18°C~30°C)
3. DRY MODE : Has 3 states, each determined
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)
4. TURBO MODE : This mode is available in
AUTO, COOL, DRY, FAN MODE.
When this button is pressed at first, the air
conditioner is operated “powerful” state for
30 minutes regardless of the set tempera-
ture, 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.
5. SLEEP MODE : Sleep mode is available
only in COOL 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.
6. FAN SPEED : Manual (3 step), Auto (4 step)
Fan speed automatically varies depending
