1. Precautions
11) Cut off the power.
● Make sure to cut off the power before repair. If not, you may
be damaged by an electric shock.
12) Do not install an outdoor unit on the apartment outside
wall(or equivalent) for safety.
● Installing an outdoor unit on the apartment outside wall(or
equivalent) is prohibited for the safety purpose. Service will
not be available for the outdoor unit where our servicemen
can not access and the cost of moving the outdoor unit to
the service area will be borne by the customer.
● If requested by the customer, you shall discourage him to
install an outdoor unit on the apartment outside wall(or
equivalent).
13) Keep the drain hose outlet free.
● Otherwise, air flow will get slow, which may hinder cooling
capacity.
● Also, dew may be laden on the service valve.
14) Use of Certified Parts
● Use certified parts only. (An electric contact part, if broken
down, shall not be repaired but replaced with a new one.
Remodeling shall be prohibited. In no case, the customer
shall repair the product on his own because this is danger-
ous enough to bring about breakdown or fire.)
15) Ban on Middle Connection of Power Cord
● Do not cut the power cord in the middle to be connected to
other power cord nor use a middle socket between two
power cords. This is dangerous enough to bring about
breakdown or fire.
16) Check Insulation
● After assembly, be sure to check insulation resistance.
(Use an insulation ohmmeter to measure the insulation
resistance between the power cord and the earthing wire.
Do not supply power until it reads 30MΩ.)
17) Be sure to keep the symmetry of the product.
● Otherwise, you may hear vibration noise.
18) Caution for Children
● Keep children off the product while it is in repair.
Otherwise, they might be endangered.
19) Be sure to put the indoor or outdoor unit free of corrosive
gases such as sulfuric water, ammonium and sulfuric
gas.
● Otherwise, copper tubes or soldered parts could be
corroded causing refrigerant leak.
10) Arrangement of surroundings
● After repair finishes, clean the air conditioner and its
surroundings and inform the customer of what it is like.

Operation Instruction & Installation
11Samsung Electronics
1. AUTO MODE : In this mode, operation mode(COOL,
HEAT) is selected automatically 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 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 tempera-
ture.(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 temperature and accumulating time of
compressor's operation.
Deice ends by sensing of the processing time by deice
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 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 automatical-
ly raised by 1°C each 1hour When the temperature
has been raised by total of 2°C, that temperature is
maintained.
*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 maintained.
7. FAN SPEED : Manual (3 step), Auto (4 step)
Fan speed automatically varies depending on both the
difference between setting and the room temperature.
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:
