1. Precautions

Samsung Electronics 1-1

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 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.

airflow near the air inlet and the air outlet.

2. Make sure that you install the unit in an area that

allows 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 (at least 1 meter clearance).

Timer indicator Temperature indicator

1) Off :

When room temperature is lowered by using the air conditioner, the gas within the thermostat

will contract and cause a break in the electrical contact. The compressor will stop.

After the compressor stops, the room temperature will rise.

2) On :

As the room temperature increases to a selected level, the gas of the thermostat expands

causing electrical contact, which provides source of electric power to the compressor.

the room temperature will fall and the cycle will repeat.

3) Control Operation :

By turning control knob clockwise(toward higher numbers), the temperature 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¡C

Cool air will be ceased below 28~32.5¡C

Level 12 : Cool air will be supplied above 11~17¡C

Cool air will be ceased below 7~13¡C

¥ Slowly turn the Fan Selector Switch in the following order : to LOW FAN, HIGH FAN, LOW COOL, HIGH COOL.

¥ OFF : All functions will be off.

¥ LOW FAN : The circulation of air is low.

¥ HIGH FAN : The circulation of air is maximum.

¥ LOW COOL : Circulation, cooling, and humidity removal are low(all simultaneousy operated).

¥ HIGH COOL : Circulation, cooling, and humidity removal are maximum(all simultaneously operated).

4-2 Checking the Oil

4-2-1 Oil quality

4-2-2 Changing and adding 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).

Put approximately 10cc oil into a transparent container and test it.
