1. Warning: Prior to repair, disconnect the
power cord from the circuit breaker.
2. Use proper parts: Use only exact replace-
ment 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 equip-
ment 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
tapping 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, mea-
sure the resistance between the power cord
and the ground terminal. The resistance
must be greater than 30 megaohms.
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 surround-
ing area.

Operating Instructions and Installation
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 controller
2. COOL MODE : The unit operates according
to the difference between the setting and
room temperature. (18°C~30°C)
3. HEAT MODE : The unit operates according
to the difference between the setting and
room temperature.(16°C~30°C)
*Prevention against cold wind : For about
3~5 minutes after initial operation, thermo
control or “de-ice”, the indoor fan will
either not operate or operate very slowly,
then switch to the selected fan speed. This
period is to allow the indoor unit's heat-
exchanger to prewarm before emitting
warm air.
*High temperature release function : The
outdoor unit for and compressor ON/OFF
control for safety operation, when the over-
heat is heat exchanger of indoor unit.
*De-ice : Deicing operation is controlled by
indoor unit's heat exchanger temperature
and accumulating time of compressor's
operation.
De-ice ends by sensing of the processing
time by de-ice Condition.
4. 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)
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 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.
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 droped by 1°C each
1hour.
When the temperature has been droped by
total of 2°C, that temperature is main-
tained.
7. FAN SPEED : Manual (3 step), Auto (4 step)
Fan speed automatically varies depending
on both the difference between setting and
the room temperature.
