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.
Fig. 1-1 Avoid Dangerous Contact
Fig. 1-2 No Tapping and No Extension Cords

3. Installation and Operating Instructions
3-1 Installation
3-1-1 Selecting Area for Installation
Select an area for installation that is suitable to the
customer’s needs.
1. Make sure that you install the unit in an area
providing good ventilation. The air conditioner
must not be blocked by any obstacles affecting the
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).
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 area not
exposed to the 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 noise.
9. Fix the unit firmly if mounted in a high place.
Caution:
It is harmful to the air conditioner if it is used in the following environments : greasy areas (including areas near
machines), salty areas such as coast areas, areas where sulfuric gas is present (such as hot spring areas), Contact
your dealer for advice.

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.

wire & switch. 2. switch is faulty.
2. check the motor 3. motor is faulty
1. check the refrigerant leakage. 1. Caused by the pipe crack
2. check the evaporator condition 2. shortage of refrigerant
( freezing, blocked with dusts, etc. ) 3. clean the evaporator & air filter.
❈Difference of temp. exists between
the suction side and the discharge
side at least 12°C
❈Standard condition
Indoor : 27°C outdoor : 35°C
1. check vibration of the pipe 1. pipes are contact with the other parts.
2. check the propeller fan and blower 2. the hex nut is loose
( not loose or broken ). 3. the parts are broken
3. check bearing noise of the motor 4. motor is faulty
4. check the compressor noise against 5. compressor is faulty
that of other compressors.
5-1-1 Check the Voltage of the power source.
5-1-2 Check weak and fragile parts.
5-1-3 Check the connection of terminals.
5-1-4 When a malfunction occurs:
➀
➁
➂
➃
The compressor does not
operate.
