1. Precautions
Samsung Electronics 1-1
1. Precautions
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
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.
Fig. 1-1 Avoid Dangerous Contact
Fig. 1-2 No Tapping and No Extension Cords
Fig. 1-3 No Kids Nearby!

3-1 Installation
3-1-1 Selecting Area for Installation
1. Make sure that you install the unit in an area
providing good ventilation. The air conditioner
must not be blocked by any obstacle affecting the
air flow near the air inlet and air outlet.
2. Make sure that you install the unit in an area that
allow good air handling. The installation area
must be able to endure vibration from the unit.
3. Make sure that you install the unit away from
heat or vapor.
4. Make sure that you install the unit in an area
which is cool and has adequate space.
5. Make sure that you install the unit in an area
away from TVs, audio units, cordless phones,
fluorescent lighting fixtures and other electrical
appliances (obtain a clearance of at least one
meter).
6. Make sure that you install the unit in an area
which provides easy drainage for condensed
water.
7. Make sure that you install the unit in an area not
exposed to rain or direct sunlight.
(Install a separate sunblind if exposed to direct
sunlight.)
8. Make sure that you install the unit in an area
allowing good air movement. Do not install it in
a space that would cause noise amplification of

3-2-1 THERMOSTAT
OFF :
When the room temperature is lowered by the air
conditioner, the gas within the thermostat will
contract and cause a break in the electric
contact. The compressor will then stop.
After the compressor stops, the room
temperature will rise
ON :
As the room temperature increases to a
selected level, the gas within the thermostat
expands, causing electric contact, which
provides the source of electric power to the
compressor. The room temperature will fall
and the cycle will repeat.
Control Operation :
By turning the control knob clockwise(toward
higher numbers), the temperatures will be cooler.
By turning the control knob counterclockwise
(toward lower numbers), the temperature will be
warmer.
Level 1 : Cool air will be supplied above 30~35°
Level 1 : Cool air will be ceased below 28~32.5°
Level 10 : Cool air will be supplied above 17.4~20.4°
Level 1 : Cool air will be ceased below 14.4~17.4°
3-2-2 Operation
The fan selector switch offers high and low fan cooling control levels to assure maximum comfort.
The two fan speeds allow you to economically circulate room air flow on days when intense cooling is
not required. When combined with the thermostat(set to call for conditioned air), these controls cool,
dehumidify, filter, and circulate room air, with the fan continuing to circulate air even when the
compressor is turned off.
3-2-3 Timer control
The timer enables the air conditioner to operate for a specified period of time, and then turns off auto-
matically while the user is sleeping, shopping, etc.. To use this function, set the ti to the desired time, and
the air conditioner will automatically shut itself off after running for the selected period ot timer.
Utility bills can be reduced and comfortable temperatures maintained with the use of the timer.
For continuous operation, set the timer control to “continue”.
3-2-4 Air swing switch
• On ( ) : Automatic oscillation distributes the air flow throughout the room.
(controls left the right and left blade-V.)
• Off ( ) : Maintains a fixed direction of air flow, Set the Air switch to OFF at the instant the wave fins
come to the desired position.

3-2-5 Fan speed switch
The fan speed switch offers high and low fan cooling control levels to assure maximum comfort.
The two fan speeds allow you to economically circulate room air flow on days when intense cooling is
not required. When combined with the thermostat(set to activate the air conditioner)hese controls cool,
dehumidify, filter, and circulate room air, with the fan continuing to circulate air while the compressor is
turned off.
3-2-6 Ventillation switch
Use the ventillation switch to exhaust stale air.
• Open position : The air inside the room circulates while the outdoor air is introduced inside.
• Closed position : The air inside the room circulates while the outdoor air is not introduced inside.
3-2-7 Energy Saver switch
The energy saver switch controls the fan.
• ENERGY SAVER OFF : The fan runs all the time, while the compressor cycle on and off.
• ENERGY SAVER ON : The fan and compressor cycle on and off together. This results in wider
variations of room temperature and humidity.
NOTE : If only the fan operation is desired, set the energy saver switch to “OFF”
The fan will not run with the switch setting combination at “FAN” of mode control and
“ON” of energy saver switch.

4-2 Checking the oil
4-2-1 Oil quality
4-2-2 Replacing and refilling the refrigerant oil
1. Change the compressor - DO NOT recharge the oil as the compressor itself is
already charged.
2. Change the condenser .... add 50cc
3. Change the evaporator .... add 50cc
4. When the refrigerant is replaced .... add 30cc oil.
5. After vacuum is completed, the oil is filled through the high pressure side.
6. In the event of a refrigerant leak, generally it is not necessary to add oil.
(Unless the oil has leaked significantly.)
Fill the transparent container with 10cc of oil, and then conduct the test.
