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
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, measure
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 surrounding
area.

Operating Instructions and Installation
Samsung Electronics3-2
1. AUTO CHANGEOVER FUNCTION :
*To operate in the “Auto change over” mode,
set the MODE on “AUTO”.
*According to the outdoor and indoor tem-
peratures while starting the operation, one of
the modes from the cooling, dehumidifying
and heating is selected automatically to
operate.
*The operation mode shall be set again if the
other condition different from that of the
operating conditions(cooling, heating, dehu-
midifying mode) is kept for 60 minutes dur-
ing the change-over operation.
1) Mode selection for operation start
2) Mode selection during the operation
2. COOL MODE : The unit operates accord-
ing to the difference between the setting
and room temperature.(setting Temp.:
18°C~30°C)
3. HEAT MODE : The unit operates accord-
ing to the difference between the setting
and room temperature.(setting Temp.:
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 until emitting
warm air.

Operating Instructions and Installation
*High temperature release function : The
outdoor unit and compressor ON/OFF is
controlled for safety operation when heat
exchanger of indoor unit is over heated.
*De-ice : Deicing operation is controlled
by outdoor unit's heat exchanger tempera-
ture and accumulating time of compres-
sor's operation.
De-ice ends by sensing of the processing
time by de-ice Condition.
4. DRY MODE :
*According to the difference between the
set temperature (Ts) and indoor tempera-
ture (Tr), the operation frequency of com-
pressor is controlled as each area.
(Cooling area/COMPor ON/OFF
area/Monitoring area)
➟ Cooling area : same as the cool mode
➟ COMPor ON/OFF area : repeat of
COMPor frequency 36[Hz] for 4 minutes
operation/0[Hz](off) for 6 minutes
➟ Monitoring area : COMPor off.
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 in “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, it is changed into
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 the difference between setting and the
room temperature.
8. COMPULSORY OPERATION :
For operating the air conditioner without
the remote controller, the tact key in
indoor unit can be used.
When started with this key, the mode is
set on “AUTO”.
The operating is the same function as
AUTO MODE in the remote controller.
Each time you press this key, 5WAY
function is changed in the following order;
STD(standard) ➝ NATURE ➝
POWER(High-speed) ➝ Saving(Power-
Saving) ➝ SILENCE
❊ STD(standard)( ) : General operation
Mode
❊ NATURE( ) : The unit is operated
according to health
pattern control
❊ POWER( ) : The unit is operated in
powerful state
❊ SAVING( ) : The unit is operated in
power saving state
❊ SILENCE( ) : The unit is operated
quitely
Each mode has Auto(Cool or Heat) operation
designed in advance.
9. SWING : BLADE-H is rotated vertically by
the stepping motor.
*Memory louver : When ON/OFF button
is pressed at stop state, the BLADE-H
returns to its original location which is
operating state before stop.
